I am using codeigniter file uploading class to upload files and images in my local folder.I am using the code below, it's working fine.
public function do_upload() {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg|pdf|txt|sql';
$config['max_size'] = 8048000;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile')) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('Emp_details_view', $error);
}
else {
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
Now, my question is how to remove previously added file when uploading new one.
You can use unlink() function to delete your previous image
unlink('image-path/image-name');
first save your filename in a database table then when unlinking take that value from database and unlink. here uploads is the foldername .
unlink("uploads/".$val['image']);
$val['image'] contains imagename from db.
I am trying to make a helper for Image Uploading. Can I extend the library inside a custom helper? I had try to use it and it never works.
<?php
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
function FileUploadd($r)
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload($r))
{
echo $this->upload->display_errors();
}
else
{
$Dder=$this->upload->data();
return $Dder['file_name'];
}
}
I see you want to call the library inside your helper and not to extend it. You should call get_instance() first because $this only works oncontrollers and models. If you want to use a helper or library you need to call the get Codeigniter's instance first
Your code should look like this:
class Your_helper_name{
private $CI;
function __construct(){
$this->CI =& get_instance();
}
function FileUploadd($r) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->CI->load->library('upload', $config);
if ( ! $this->CI->upload->do_upload($r))
{
echo $this->CI->upload->display_errors();
}
else
{
$Dder=$this->CI->upload->data();
return $Dder['file_name'];
}
}
}
Let me know if you need clarification. If this answers your question, please mark this as answer. Thanks!
i am using simple ci file uploading class , it works fine on localserver but when shifting it to production server it does not work , it simply says page not responding ..
Can any one help on this ..
Please check my code
<?php
class Upload extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
public function index()
{
$this->load->view('upload_form', array('error' => ' ' ));
}
public function do_upload()
{
$config['upload_path'] = './assets/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile'))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
}
?>
You’ll need a destination directory for your uploaded images set file permissions to 777.
I'm brand new to codeigniter and am trying to rename my image to be the next auto incremented number in the table.
I was looking into using
$id = $this->db->insert_id();
But am still unsure how to add 1 to that value and use it for my file name. I've got image resizing all set just need to rename and I'm set.
Any help would be much appreciated!!! Thanks so much!
Controller:
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if ( !$this->upload->do_upload() )
{
$error = array('error' => $this->upload->display_errors());
redirect('index.php/success');
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->resize($data['upload_data']['full_path'], $data['upload_data']['file_name']);
redirect('index.php/success');
echo $img;
}
// Update Record to save filename
}
function resize($path, $file){
$config['image_library']= 'gd2';
$config['source_image']= $path;
$config['create_thumb']= TRUE;
$config['maintain_ration']= TRUE;
$config['width']= 320;
$config['height']= 196;
$config['new_image']='./uploads/'.$file;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
Get the last number of the id column which you have set to auto increment.You can use sql Max() function to that.Then simply add a 1 to that and use it for the image renaming.That's it!!!
In view
<?php echo form_open_multipart('welcome/do_upload');?>
<input type="file" name="userfile" size="20" />
In controler
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['overwrite'] = TRUE;
$config['encrypt_name'] = FALSE;
$config['remove_spaces'] = TRUE;
if ( ! is_dir($config['upload_path']) ) die("THE UPLOAD DIRECTORY DOES NOT EXIST");
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile')) {
echo 'error';
} else {
return array('upload_data' => $this->upload->data());
}
}
And I call this function like this
$this->data['data'] = $this->do_upload();
and view this image:
<ul>
<?php foreach ($data['upload_data'] as $item => $value):?>
<li><?php echo $item;?>: <?php echo $value;?></li>
<?php endforeach; ?>
</ul>
I don't know what's the error.
It seems the problem is you send the form request to welcome/do_upload, and call the Welcome::do_upload() method in another one by $this->do_upload().
Hence when you call the $this->do_upload(); within your second method, the $_FILES array would be empty.
And that's why var_dump($data['upload_data']); returns NULL.
If you want to upload the file from welcome/second_method, send the form request to the welcome/second_method where you call $this->do_upload();.
Then change the form helper function (within the View) as follows1:
// Change the 'second_method' to your method name
echo form_open_multipart('welcome/second_method');
File Uploading with CodeIgniter
CodeIgniter has documented the Uploading process very well, by using the File Uploading library.
You could take a look at the sample code in the user guide; And also, in order to get a better understanding of the uploading configs, Check the Config items Explanation section at the end of the manual page.
Also there are couple of articles/samples about the file uploading in CodeIgniter, you might want to consider:

http://hashem.ir/CodeIgniter/libraries/file_uploading.html (CodeIgniter 3.0-dev User Guide)
Just as a side-note: Make sure that you've loaded the url and form helper functions before using the CodeIgniter sample code:
// Load the helper files within the Controller
$this->load->helper('form');
$this->load->helper('url');
// Load the helper files within the application/config/autoload
$autoload['helper'] = array('form', 'url');
1. The form must be "multipart" type for file uploading. Hence you should use `form_open_multipart()` helper function which returns:

Simple Image upload in codeigniter
Find below code for easy image upload:
public function doupload()
{
$upload_path="https://localhost/project/profile"
$uid='10'; //creare seperate folder for each user
$upPath=upload_path."/".$uid;
if(!file_exists($upPath))
{
mkdir($upPath, 0777, true);
}
$config = array(
'upload_path' => $upPath,
'allowed_types' => "gif|jpg|png|jpeg",
'overwrite' => TRUE,
'max_size' => "2048000",
'max_height' => "768",
'max_width' => "1024"
);
$this->load->library('upload', $config);
if(!$this->upload->do_upload('userpic'))
{
$data['imageError'] = $this->upload->display_errors();
}
else
{
$imageDetailArray = $this->upload->data();
$image = $imageDetailArray['file_name'];
}
}
//this is the code you have to use in you controller
$config['upload_path'] = './uploads/';
// directory (http://localhost/codeigniter/index.php/your directory)
$config['allowed_types'] = 'gif|jpg|png|jpeg';
//Image type
$config['max_size'] = 0;
// I have chosen max size no limit
$new_name = time() . '-' . $_FILES["txt_file"]['name'];
//Added time function in image name for no duplicate image
$config['file_name'] = $new_name;
//Stored the new name into $config['file_name']
$this->load->library('upload', $config);
if (!$this->upload->do_upload() && !empty($_FILES['txt_file']['name'])) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('production/create_images', $error);
} else {
$upload_data = $this->upload->data();
}
Change the code like this. It works perfectly:
public function uploadImageFile() //gallery insert
{
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$new_image_name = time() . str_replace(str_split(' ()\\/,:*?"<>|'), '',
$_FILES['image_file']['name']);
$config['upload_path'] = 'uploads/gallery/';
$config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
$config['file_name'] = $new_image_name;
$config['max_size'] = '0';
$config['max_width'] = '0';
$config['max_height'] = '0';
$config['$min_width'] = '0';
$config['min_height'] = '0';
$this->load->library('upload', $config);
$upload = $this->upload->do_upload('image_file');
$title=$this->input->post('title');
$value=array('title'=>$title,'image_name'=>
$new_image_name,'crop_name'=>$crop_image_name);}
$image_folder = APPPATH . "../images/owner_profile/" . $_POST ['mob_no'] [0] . $na;
if (isset ( $_FILES ['image'] ) && $_FILES ['image'] ['error'] == 0) {
list ( $a, $b ) = explode ( '.', $_FILES ['image'] ['name'] );
$b = end ( explode ( '.', $_FILES ['image'] ['name'] ) );
$up = move_uploaded_file ( $_FILES ['image'] ['tmp_name'], $image_folder . "." . $b );
$path = ($_POST ['mob_no'] [0] . $na . "." . $b);
Below code for an uploading a single file at a time.
This is correct and perfect to upload a single file.
Read all commented instructions and follow the code.
Definitely, it is worked.
public function upload_file() {
***// Upload folder location***
$config['upload_path'] = './public/upload/';
***// Allowed file type***
$config['allowed_types'] = 'jpg|jpeg|png|pdf';
***// Max size, i will set 2MB***
$config['max_size'] = '2024';
$config['max_width'] = '1024';
$config['max_height'] = '768';
***// load upload library***
$this->load->library('upload', $config);
***// do_upload is the method, to send the particular image and file on that
// particular
// location that is detail in $config['upload_path'].
// In bracks will set name upload, here you need to set input name attribute
// value.***
if($this->upload->do_upload('upload')) {
$data = $this->upload->data();
$post['upload'] = $data['file_name'];
} else {
$error = array('error' => $this->upload->display_errors());
}
}
check $this->upload->initialize($config); this works fine for me
$new_image_name = "imgName".time() . str_replace(str_split(' ()\\/,:*?"<>|'), '',
$_FILES['userfile']['name']);
$config = array();
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
$config['file_name'] = $new_image_name;
$config['max_size'] = '0';
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|mp4|jpeg';
$config['file_name'] = url_title("imgsclogo");
$config['max_size'] = '0';
$config['overwrite'] = FALSE;
$this->upload->initialize($config);
$this->upload->do_upload();
$data = $this->upload->data();
}
