I have created a helper that requires some parameters and should upload a file, the function works for images however not for zip files. I searched on google and even added a MY_upload.php -> http://codeigniter.com/bug_tracker/bug/6780/
however I still have the problem so I used print_r to display the array of the uploaded files, the image is fine however the zip array is empty:
Array
(
[file_name] =>
[file_type] =>
[file_path] =>
[full_path] =>
[raw_name] =>
[orig_name] =>
[file_ext] =>
[file_size] =>
[is_image] =>
[image_width] =>
[image_height] =>
[image_type] =>
[image_size_str] =>
)
Array
(
[file_name] => 2385b959279b5e3cd451fee54273512c.png
[file_type] => image/png
[file_path] => I:/wamp/www/e-commerce/sources/images/
[full_path] => I:/wamp/www/e-commerce/sources/images/2385b959279b5e3cd451fee54273512c.png
[raw_name] => 2385b959279b5e3cd451fee54273512c
[orig_name] => 1269770869_Art_Artdesigner.lv_.png
[file_ext] => .png
[file_size] => 15.43
[is_image] => 1
[image_width] => 113
[image_height] => 128
[image_type] => png
[image_size_str] => width="113" height="128"
)
this is the function helper
function multiple_upload($name = 'userfile', $upload_dir = 'sources/images/', $allowed_types = 'gif|jpg|jpeg|jpe|png', $size)
{
$CI =& get_instance();
$config['upload_path'] = realpath($upload_dir);
$config['allowed_types'] = $allowed_types;
$config['max_size'] = $size;
$config['overwrite'] = FALSE;
$config['encrypt_name'] = TRUE;
$ffiles = $CI->upload->data();
echo "<pre>";
print_r($ffiles);
echo "</pre>";
$CI->upload->initialize($config);
$errors = FALSE;
if(!$CI->upload->do_upload($name))://I believe this is causing the problem but I'm new to codeigniter so no idea where to look for errors
$errors = TRUE;
else:
// Build a file array from all uploaded files
$files = $CI->upload->data();
endif;
// There was errors, we have to delete the uploaded files
if($errors):
#unlink($files['full_path']);
return false;
else:
return $files;
endif;
}//end of multiple_upload()
and this is the code in my controller
if(!$s_thumb = multiple_upload('small_thumb', 'sources/images/', 'gif|jpg|jpeg|jpe|png', 1024)): //http://www.matisse.net/bitcalc/
$data['feedback'] = '<div class="error">Could not upload the small thumbnail!</div>';
$error = TRUE;
endif;
if(!$main_file = multiple_upload('main_file', 'sources/items/', 'zip', 307200)):
$data['feedback'] = '<div class="error">Could not upload the main file!</div>';
$error = TRUE;
endif;
found the solution -> codeigniter.com/forums/viewthread/149027 Adding force-download to the allowed mime types
I got 'application/octet-stream' in $_FILES['your_file_name']['type'] , so I had to add 'application/octet-stream' in the mime types for 'zip' (in /config/mimes.php) .
The value of $_FILES['your_file_name']['type'] seems to differ based on browser/platform.

I created a custom form from a buildForm function. In this form, I would like add an image field.
I can do that via this code :
$form['main']['image'] = array(
'#type' => 'text_format',
'#title' => t('image'),
'#default_value' => array(10),
);
I can upload and remove the image from my form. However, when I upload an image, I haven't this preview.
I mean, when I create a content via the Drupal UI. I can add a preconfigured "image" field. When I upload an image via this "image" field, I have a preview of the image.
And here, when I create the field element programmatically, I haven't a preview of the image when I upload her.
How use api Drupal for have the preview of the image when I upload her via my "image" field ?
So here is how I got my form to display the thumbnail image. What I basically did was take the code in ImageWidget::process, put it in a theme preprocessor and set the #theme property of the element to image_widget.
Your image element in your form class should look like this:
$form['profile_image'] = [
'#type' => 'managed_file',
'#title' => t('Profile Picture'),
'#upload_validators' => array(
'file_validate_extensions' => array('gif png jpg jpeg'),
'file_validate_size' => array(25600000),
),
**'#theme' => 'image_widget',**
**'#preview_image_style' => 'medium',**
'#upload_location' => 'public://profile-pictures',
'#required' => TRUE,
];
In your name_of_default_theme.theme file, you need the following:
function name_of_default_theme_preprocess_image_widget(&$variables) {
$element = $variables['element'];
$variables['attributes'] = array('class' => array('image-widget', 'js-form-managed-file', 'form-managed-file', 'clearfix'));
if (!empty($element['fids']['#value'])) {
$file = reset($element['#files']);
$element['file_' . $file->id()]['filename']['#suffix'] = ' <span class="file-size">(' . format_size($file->getSize()) . ')</span> ';
$file_variables = array(
'style_name' => $element['#preview_image_style'],
'uri' => $file->getFileUri(),
);
// Determine image dimensions.
if (isset($element['#value']['width']) && isset($element['#value']['height'])) {
$file_variables['width'] = $element['#value']['width'];
$file_variables['height'] = $element['#value']['height'];
} else {
$image = \Drupal::service('image.factory')->get($file->getFileUri());
if ($image->isValid()) {
$file_variables['width'] = $image->getWidth();
$file_variables['height'] = $image->getHeight();
}
else {
$file_variables['width'] = $file_variables['height'] = NULL;
}
}
$element['preview'] = array(
'#weight' => -10,
'#theme' => 'image_style',
'#width' => $file_variables['width'],
'#height' => $file_variables['height'],
'#style_name' => $file_variables['style_name'],
'#uri' => $file_variables['uri'],
);
// Store the dimensions in the form so the file doesn't have to be
// accessed again. This is important for remote files.
$element['width'] = array(
'#type' => 'hidden',
'#value' => $file_variables['width'],
);
$element['height'] = array(
'#type' => 'hidden',
'#value' => $file_variables['height'],
);
}
$variables['data'] = array();
foreach (Element::children($element) as $child) {
$variables['data'][$child] = $element[$child];
}
}
The solution works well, but the image module is missing a class with the #FormElement annotation. That is why the element isn't rendered properly.
Can you try with managed_file type?
'#type' => 'managed_file'
First some clarifications, then some observations and then the code that worked for me.
Clarifications:
I am using Drupal 9, but the solution proposed below may work also
for Drupal 8.
By "default temporary directory" I mean the directory defined in the following settings
file
[DrupalrootDirectory]/sites/default/settings.php
using
$settings['file_temp_path'] = '/The/Absolute/Path/To/Your/Temporary/Directory';
or defined by your operating system and that you can check in the Drupal administration
menu:
[YourSiteWebAddress]/admin/config/media/file-system
When something is written inside square brackets [], like this, [DrupalrootDirectory], it means that you should replace it with the actual name in your system, Drupal installation or custom module/file, without the square brackets.
Observations:
No need to create apriory any directories inside the default
temporary directory. They will be created automatically.
When you click the Remove button (which appears automatically as soon you upload a file in your custom form), the image file and the thumbnail files are deleted from the default temporary directory.
It does not matter if you define your default temporary directory inside the default site location,
e.g.,
[DrupalrootDirectory]/sites/default/files
or outside it, for example,
[DrupalrootDirectory]/sites/other/files
In my case, I defined it to:
[DrupalrootDirectory]/sites/default/files/temp
No need to make changes to .htaccess (in Apache server) file inside the default temporary directory or
inside
[DrupalrootDirectory]/sites/default/files
Keep them as Drupal created them.
No need to change file rights to "777" inside the default temporary directory, "775" is enough.
Check that your Drupal installation is actually creating thumbnails for images uploaded using the
administration menu:
[YourSiteWebAddress]/admin/content/media
when using the "Add media" link
[YourSiteWebAddress]/media/add/image
No need to make any other changes inside Drupal settings
file
[DrupalrootDirectory]/sites/default/settings.php
The code that worked for me:
It is based in the code published above by "Je Suis Alrick". But his code was not working for me, neither I could not find in which part of his code the thumbnail image was actually created. In my search for it, this post helped
Generate programmatically image styles with Drupal 8
So, here is the final code:
In your custom module, in the custom form file, most probably located
in:
[DrupalrootDirectory]/modules/custom/[NameOfYourCustomModule]/src/Form/[NameOfYourCustomForm].php
you add the element to be used to upload the image file:
$form['profile_image'] = [
'#type' => 'managed_file',
'#title' => t('Profile Picture'),
'#upload_validators' => array(
'file_validate_extensions' => array('gif png jpg jpeg'),
'file_validate_size' => array(25600000),
),
'#theme' => 'image_widget',
'#preview_image_style' => 'medium',
'#required' => TRUE,
];
So far, the same as in the code of "Je Suis Alrick", except that I deleted the definition for '#upload_location', so the default temporary directory will be used avoiding security complaints.
The important part here is:
the definition of the '#theme', which may be any name, but in this case is 'image_widget';
and the definition of '#preview_image_style', which must be the machine name of one of the image styles defined in your Drupal installation, that you can check in your administration
menu
[YourSiteWebAddress]/admin/config/media/image-styles
For this case the style 'medium' will be used, which is one of the image styles created by default by Drupal.
Then, in the module file of your custom module, named [NameOfYourCustomModule].module and most probably located
in:
[DrupalrootDirectory]/modules/custom/[NameOfYourCustomModule]/
You will need to paste the following code:
<?php
use Drupal\image\Entity\ImageStyle;
function [NameOfYourCustomModule]_preprocess_image_widget(&$variables) {
$element = $variables['element'];
$variables['attributes'] = array('class' => array('image-widget', 'js-form-managed-file', 'form-managed-file', 'clearfix'));
if (!empty($element['fids']['#value'])) {
$file = reset($element['#files']);
$element['file_' . $file->id()]['filename']['#suffix'] = ' <span class="file-size">(' . format_size($file->getSize()) . ')</span> ';
$file_variables = array(
'style_name' => $element['#preview_image_style'],
'uri' => $file->getFileUri(),
);
// Determine image dimensions.
if (isset($element['width']['#value']) && isset($element['height']['#value'])) {
$file_variables['width'] = $element['width']['#value'];
$file_variables['height'] = $element['height']['#value'];
} else {
$image = \Drupal::service('image.factory')->get($file->getFileUri());
if ($image->isValid()) {
$file_variables['width'] = $image->getWidth();
$file_variables['height'] = $image->getHeight();
$style = ImageStyle::load($file_variables['style_name']);
$image_uri = $file->getFileUri();
$destination = $style->buildUri($image_uri);
$style->createDerivative($image_uri, $destination);
}
else {
$file_variables['width'] = $file_variables['height'] = NULL;
}
}
$element['preview'] = array(
'#weight' => -10,
'#theme' => 'image_style',
'#width' => $file_variables['width'],
'#height' => $file_variables['height'],
'#style_name' => $file_variables['style_name'],
'#uri' => $file_variables['uri'],
);
// Store the dimensions in the form so the file doesn't have to be
// accessed again. This is important for remote files.
$element['width'] = array(
'#type' => 'hidden',
'#value' => $file_variables['width'],
);
$element['height'] = array(
'#type' => 'hidden',
'#value' => $file_variables['height'],
);
}
$variables['data'] = array();
foreach (\Drupal\Core\Render\Element::children($element) as $child) {
$variables['data'][$child] = $element[$child];
}
}
You should note that at the end of the name of the function, the name of the theme 'image_widget' is included, which tells Drupal to process your form element using the defined above function: [NameOfYourCustomModule]_preprocess_image_widget
What have I added?
The line at the
top:
use Drupal\image\Entity\ImageStyle;
And the following four lines that actually create the image thumbnail inside the default temporary directory:
$style = ImageStyle::load($file_variables['style_name']);
$image_uri = $file->getFileUri();
$destination = $style->buildUri($image_uri);
$style->createDerivative($image_uri, $destination);
With the addition of these five lines I got it working!
Nice answer thx, only change I'd make is using Token for upload location, and Bytes for file upload size, although I guess it depends on the use case. Something like the below (stripped out most of the code for the sake of simplicity.
namespace Drupal\my_module\Form;
use Drupal\Core\Form\FormBase;
use Drupal\Core\Form\FormStateInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Drupal\Core\Session\AccountProxyInterface;
use Drupal\Component\Utility\Bytes;
use Drupal\Core\Utility\Token;
class SampleForm extends FormBase
{
protected $currentUser;
protected $token;
public function __construct(AccountProxyInterface $current_user, Token $token) {
$this->currentUser = $current_user;
$this->token = $token;
}
public static function create(ContainerInterface $container)
{
return new static(
$container->get('current_user'),
$container->get('token')
);
}
/**
* {#inheritdoc}
*/
public function buildForm(array $form, FormStateInterface $form_state) {
$form['sample_image'] = [
'#type' => 'managed_file',
'#title' => t('Profile Picture'),
'#upload_validators' => array(
'file_validate_extensions' => array('gif png jpg jpeg'),
'file_validate_size' => file_upload_max_size() / pow(Bytes::KILOBYTE, 2) . 'M',
),
'#theme' => 'image_widget',
'#preview_image_style' => 'medium',
'#upload_location' => $this->token->replace('private://[date:custom:Y]-[date:custom:m]'),
'#required' => TRUE,
];
return $form;
}
}

i am using drupal_validate_form on a node listing page .
it is validating it correctly only for 1st item after that it is not checking validation.
here is my code
foreach($result as $r){
$node_form = (object) array(
'uid' => $user->uid,
'type' => 'MY_CONTENT_TYPE',
'language' => LANGUAGE_NONE,
);
$form = drupal_get_form('MY_CONTENT_TYPE_node_form',$node_form);
$form['#submit'] = array('#type' => 'submit', '#value' => t('Next'));
$old_fs = #unserialize($r->form_state);
$old_fs['values']['uid'] = $user->uid;
$node = (object) array(
'uid' => $user->uid,
'type' => 'MY_CONTENT_TYPE',
'language' => LANGUAGE_NONE,
);
node_object_prepare($node);
$form_state = array();
$form_state['build_info']['args'] = array($node);
$form_state['values'] = $old_fs['values'];
$form_state['values']['op'] = t('Save');
$form_state['submitted'] = 1;
$form_state['complete form'] = array();
$form_state['triggering_element'] = array('#parents'=>array('next'),'#button_type'=>'submit');
unset($form['#token']);
drupal_validate_form('MY_CONTENT_TYPE_node_form', $form, $form_state);
$errors = form_get_errors();
$noOfError = 'empty';
if (!empty($errors)) {
$noOfError = count($errors);
}
form_clear_error();
}
thank You in advance
Finally i have to reset need_validation in $form .
Because every time form get for validation it will chack $form['#needs_validation'] in _form_validate();
so i added another line after
$form = drupal_get_form('MY_CONTENT_TYPE_node_form',$node_form);
$form['#needs_validation'] = TRUE;
and it will validate every form in that loop
I'm running over this problem which I was trying for the last few hours
I'm having an image upload with some details to store in db.
I store the details and image path, working like a charm. Now comes the edit part.
I'm trying to check if the input file is empty, if so update just the details, else delete the image and reupload new image. The problem is this:
If the input file is empty it updates everything no problem, if is not empty it is updating the details, but the image is the same, doesn't get deleted or reuploaded.
here is the code
$image_input = $this->input->post('image');
if(isset($image_input) && !empty($image_input))
{
$this->db->where('id', $id);
$img = $this->db->get('menus_category', 1);
if($img->num_rows() > 0)
{
$row = $img->row();
$original_image = $row->image;
$desktop_image = $row->desk_img;
$mobile_image = $row->mob_img;
$thumb_image = $row->thumb;
$unlink_image = unlink('./uploads/menus/' . $original_image);
$unlink_desk = unlink('./uploads/menus/desk/' . $desktop_image);
$unlink_mob = unlink('./uploads/menus/mobile/' . $mobile_image);
$unlink_thumb = unlink('./uploads/menus/thumbs/' . $thumb_image);
if($unlink_desk && $unlink_image && $unlink_mob && $unlink_thumb)
{
$config = array(
'upload_path' => './uploads/menus',
'allowed_types' => 'gif|jpg|jpeg|png',
'max_size' => '15000'
);
$this->upload->initialize($config);
if ($this->upload->do_upload('image'))
{
$image_data = $this->upload->data();
$this->load->library('image_lib');
// thumb resize
$thumbnail = 'thumb_' . $image_data['file_name'];
$thumb = array(
'image_library' => 'GD2',
'source_image' => $image_data['full_path'],
'new_image' => $image_data['file_path'] . 'thumbs/' . $thumbnail,
'maintain_ratio' => TRUE,
'width' => '90',
'height' => '90'
);
$this->image_lib->initialize($thumb);
$this->image_lib->resize();
$this->image_lib->clear();
// mobile resize
$mob = 'mob_' . $image_data['file_name'];
$thumb_mob = array(
'image_library' => 'GD2',
'source_image' => $image_data['full_path'],
'new_image' => $image_data['file_path'] . 'mobile/' . $mob,
'maintain_ratio' => FALSE,
'width' => '290',
'height' => '83'
);
$this->image_lib->initialize($thumb_mob);
$this->image_lib->resize();
$this->image_lib->clear();
// desktop resize
$desk = 'desk_' . $image_data['file_name'];
$thumb_desk = array(
'image_library' => 'GD2',
'source_image' => $image_data['full_path'],
'new_image' => $image_data['file_path'] . 'desk/' . $desk,
'maintain_ratio' => FALSE,
'width' => '700',
'height' => '200'
);
$this->image_lib->initialize($thumb_desk);
$this->image_lib->resize();
$this->image_lib->clear();
// insert path and details to database
$data = array(
'title' => $input['title'],
'slug' => $this->_check_slug($input['title']),
'description' => $input['description'],
'image' => $image_data['file_name'],
'desk_img' => $desk,
'mob_img' => $mob,
'thumb' => $thumbnail
);
$this->db->where('id', $id);
return $this->db->update('menus_category', $data);
}
else
{
echo $this->image_lib->display_errors();
}
}
}
}
else
{
$data2 = array(
'title' => $input['title'],
'slug' => $this->_check_slug($input['slug']),
'description' => $input['description']
);
$this->db->where('id', $id);
return $this->db->update('menus_category', $data2);
}
Note: the else statement works fine, but the first if the problem. Now I changed the if to just if(isset($image_input)) ... and if file input is not empty is reuploading the picture and updating the details fine, but if I update only the details with no picture, it is deleting the picture that is already uploaded and is not updating. (I think this is the problem but I can't figure out how to fix it).
If you will to give me some help or to put me on right direction I will be thankful.
Thanks guys
First, this would be a comment asking a question, but I don't have enough reputation do add one just yet...
If you could post your HTML form, that would be helpful, but without that...
1) I assume the form you are submitting has enctype="multipart/form-data" in the opening tag.
2) On line 2 of your code here, $this->input->post('image'), is 'image' from a form input of type file? If so, your statement won't work as 'image' is part of the $_FILES array and not $_POST anymore. Meaning when you go to check it, it is always going to be empty (or non-existent).
To verify that your form is submitting the way you think it is, do this just before the first line in the code you have in your post:
var_dump($_POST);
var_dump($_FILES);
exit; // don't let anything run after the dumps.
let me know if that puts you in the right direction or not.
Having a little trouble in getting image attachment urls in wordpress. This is my code so far:
<?php // find images attached to this post / page.
global $post;
$thumb_ID = get_post_thumbnail_id( $post->ID );
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'numberposts' => -1,
'orderby' => 'menu_order',
'order' => 'ASC',
'exclude' => $thumb_ID,
'post_parent' => $post->ID
);
$images = get_posts($args);
?>
<?php // Loop through the images and show them
if($images)
{
foreach($images as $image)
{
echo wp_get_attachment_image_url($image->ID, $size='attached-image');
}
}
?>
Which returns nothing. If I swap out wp_get_attachment_image_url($image->ID, $size='attached-image'); for wp_get_attachment_image($image->ID, $size='attached-image'); this works fine, but brings in the image rather than just the url.
The following code will loop through all image attachments and output the src url. Note that there are two methods shown, depending on your need.
<?php
global $post;
$args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_mime_type' => 'image', 'post_status' => null, 'post_parent' => $post->ID );
$attachments = get_posts($args);
if ($attachments) {
foreach ( $attachments as $attachment ) {
// Method #1: Allows you to define the image size
$src = wp_get_attachment_image_src( $attachment->ID, "attached-image");
if ($src) {echo $src[0];}
// Method #2: Would always return the "attached-image" size
echo $attachment->guid;
}
}
?>
i have a problem while uploading and resizing images in a loop.
can anyone please provide me the working sample of code of codeigniter for uploading and resizing at the same time in a loop.
I want to upload and resize images uploaded from the form. There will be more than 1 images so i have to upload them in loop.
My code first uploads the image then resizes it. 1ts images is uploaded and resized correctly but during 2nd loop the image is uploaded but not resized. It throws this error:
Your server does not support the GD
function required to process this type
of image.
I have tried the clear function too
$this->image_lib->clear();
can anyone please help
Dont load image_lib multiple times. Add image_lib in autoload libs and change
$this->load->library('image_lib', $config);
to
$this->image_lib->initialize($config);
I had the same problem but this seemed to work:
// Do upload
if (! $this->upload->do_upload($image_name)) {
// return errors
return array('errors' => $this->upload->display_errors());
}
$data = $this->upload->data();
$config_manip = array(
'image_library' => 'gd2',
'source_image' => "./assets/uploads/{$data['file_name']}",
'new_image' => "./assets/uploads/thumbs/{$data['file_name']}",
'create_thumb' => true,
'thumb_marker' => '',
'maintain_ratio' => true,
'width' => 140,
'height' => 140
);
// Create thumbnail
$this->load->library('image_lib');

Notice the Create Thumbnail goes:
Load Library,
Resize Image,
CLEAR,
Initialize Config
I was putting the clear after the initialize which was causing the same error you're getting.
Here is a working code from my image gallery controller. This function uploads a batch of images, resizes them and saves them to database.
public function create_photo_batch() {
$this->load->library('image_lib');
$this->load->library('upload');
// Get albums list for dropdown
$this->data['albums'] = $this->gallery_m->get_albums_list();
if(isset($_FILES['images']) && $_FILES['images']['size'] > 0) {
$album_id = $this->input->post('albumid');
$images = array();
$ret = array();
// Upload
$files = $_FILES['images'];
foreach ($files['name'] as $key => $image) {
$_FILES['images[]']['name']= $files['name'][$key];
$_FILES['images[]']['type']= $files['type'][$key];
$_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
$_FILES['images[]']['error']= $files['error'][$key];
$_FILES['images[]']['size']= $files['size'][$key];
$upload_config = array(
'allowed_types' => 'jpg|jpeg|gif|png',
'upload_path' => realpath(APPPATH . "../uploads/gallery"),
'max_size' => 5000,
'remove_spaces' => TRUE,
'file_name' => md5(time())
);
$this->upload->initialize($upload_config);
if ($this->upload->do_upload('images[]')) {
$image_data = $this->upload->data();
$images[] = $image_data['file_name'];
} else {
$this->session->set_flashdata('error', $this->upload->display_errors() );
redirect('admin/gallery/create_photo_batch');
}
}
// Resize
foreach ($images as $image) {
$resize_config = array(
'source_image' => realpath(APPPATH . '../uploads/gallery') .'/'. $image,
'new_image' => realpath(APPPATH . '../uploads/gallery/thumbs'),
'maintain_ratio' => TRUE,
'width' => 500,
'height' => 500
);
$this->image_lib->initialize($resize_config);
if ( ! $this->image_lib->resize() ) {
echo $this->image_lib->display_errors();
die;
}
$this->image_lib->clear();
}
// Save to db
foreach ($images as $image) {
$ret[] = array(
'AlbumID' => (int) $album_id,
'Url' => $image,
'IsActive' => 1
);
}
$this->gallery_m->save_images($ret);
redirect('admin/gallery/album/'.$album_id);
}
//Load view
$this->data['subview'] = 'admin/gallery/photo_upload_batch_view';
$this->load->view('admin/_layout_main', $this->data);
}
Your error message suggest that it's not the loop that is the problem, but rather that the 2nd file is of a different filetype than the 1st. And that the underlying server don't have the needed libraries (http://www.libgd.org/Main_Page) installed to handle that file type.
$config['image_library'] = 'gd2';
$config['source_image'] = './assets/upload_images/A.jpg';
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 1600;
$config['height'] = 900;
$config['new_image'] = './assets/upload_images/'.$randy;
$this->load->library('image_lib', $config);
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
I had same problem but solved these by this code.
