CodeIgniter renaming image to be the next id in db table - image

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!!!

How to remove existing file when uploading new one in codeigniter file uploading?

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.

how to get upload file name in codeigniter

Hi i'm trying to upload image to a folder and image name in database
in view
echo form_open_multipart('subscribers_c/actioncreate',array('class'=>'form'));`enter code here`
<input type='file' name='img'>
in controller
$config['upload_path'] ='./assets/uploads/subscribers_photos'; //The path where the image will be save
$config['allowed_types'] = 'gif|jpg|png'; //Images extensions accepted
$config['max_size'] = '2048';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config); //Load the upload CI library
if (!$this->upload->do_upload('img'))
{
$uploadError = array('upload_error' => $this->upload->display_errors());
//$this->set_flashdata('msg_error', $uploadError, site_url().'/subscribers_c/actioncreate');
}
$file_info = $this->upload->data('img');
$img_name = $file_info['file_name'];
$data=array(
'chit_fund_id'=>$this->input->post('cid'),
'first_name'=>$this->input->post('fname'),
'last_name'=>$this->input->post('lname'),
'dob'=>$this->input->post('bd'),
'gender'=>$this->input->post('g'),
'contact_number'=>$this->input->post('mob'),
'address'=>$this->input->post('add'),
'email_id'=>$this->input->post('eml'),
'bid_status'=>$this->input->post('b_status'),
'user_status'=>$this->input->post('u_status'),
'image_name'=>$img_name,
);
//print_r($data);
image_name is not having any value
how to get image name .
Instead of img in upload data
$file_info = $this->upload->data('img');
Try
$file_info = $this->upload->data();
$img = $file_info['file_name'];
And on here $config['upload_path'] = './assets/uploads/subscribers_photos'; end with /
Like $config['upload_path'] = './assets/uploads/subscribers_photos/';
Inside the view call the form_upload function(if needed, your one is also correct):
<?php echo form_upload('pic'); ?>
Inside controller function for upload:
$img_name = $_FILES["pic"]["name"];
By using this code you will get the file name.
$img_name = $this->upload->data('file_name');

How to upload image in CodeIgniter?

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://code.tutsplus.com/tutorials/how-to-upload-files-with-codeigniter-and-ajax--net-21684
http://runnable.com/UhIc93EfFJEMAADX/how-to-upload-file-in-codeigniter

http://code.tutsplus.com/tutorials/how-to-upload-files-with-codeigniter-and-ajax--net-21684
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();
}

upload size limit in codeigniter

I have a page where user can register. He uploads a profile picture in the process. I want to limit the size but there is not much emphasis on codeigniter documentation except for $config['maxsize']. I tried the following but I don't get any messages. I set the size to 10 (KB) just for testing. Do I have to handle it somehow to get the message across to my view?
public function add_user()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '10';
//$config['max_width'] = '1024';
//$config['max_height'] = '768';
$this->load->library('upload', $config);
$fullImagePath;
if (isset($_FILES['userfile']) && !empty($_FILES['userfile']['name']))
{
if ($this->upload->do_upload('userfile'))
{
// set a $_POST value for 'image' that we can use later
...
By the way this code is in my Model.
#Chetan Wadhwa,
Are you sure the size is in Bytes(Not in KB). Refer codeigniter documentation: http://www.codeigniter.com/user_guide/libraries/file_uploading.html, must be in KB.
This Size is not in KB it is in Bytes so for 10KB you should write (10*1024) Bytes or "10240"
You don't need to handle the error message CI will take care that in this case so please follow the upload class tutorial which specified in codeIgniter userguide.
<?php
class upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index()
{
$this->load->view('upload_form', array('error' => ' ' ));
}
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';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$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);
}
}

CodeIgniter - Write file names to database from multiple images

I have an upload form with two file upload fields. I am trying to upload the files, and then write the file names to the same row in a database. I have everything working except the file names get written to their own row. I am guessing it's because I am making two separate calls to the model, but I am not sure how to go about doing it in one call since they each have their own "if" statement.
To make my question clear. How do I write the names of two uploaded files to the same row in the database?
Any ideas would be great. This is the code I am working with. Thanks.
View:
<?php echo form_open_multipart('upload_controller'); ?>
<p>
<input type="file" name="userfile">
</p>
<p>
<input type="file" name="userfile1">
</p>
<p><?php echo form_submit('submit', 'Upload them files!') ?></p>
<?php form_close() ?>
Controller:
if (isset($_POST['submit'])) {
$this->load->library('upload');
if (!empty($_FILES['userfile']['name'])) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->upload->initialize($config);
// Upload file 1
if ($this->upload->do_upload('userfile')) {
$img = $this->upload->data();
$file_name = $img['file_name'];
$this->load->model('upload_file', 'upload_model');
$this->upload_model->upload_file1($file_name);
}
}
if (!empty($_FILES['userfile1']['name'])) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->upload->initialize($config);
// Upload file 2
if ($this->upload->do_upload('userfile1')) {
$img = $this->upload->data();
$file_name = $img['file_name'];
$this->load->model('upload_file', 'upload_model');
$this->upload_model->upload_file2($file_name);
} else {
echo $this->upload->display_errors();
}
}
} else {
$this->load->view("upload_form");
}
Model:
public function upload_file1($file_name) {
$data = array('file1' => $file_name);
$this->db->insert('images_table', $data);
}
public function upload_file2($file_name) {
$data = array('file2' => $file_name);
$this->db->insert('images_table', $data);
}
Database row:
| id | file1 | file2 |
Try like this(if you have the number of files....in your case it is "2" )
$this->load->model('upload_file', 'upload_model');
for($i=1;$i<=$numimg;$i++) //in your case $numimg = 2;
{
if($this->upload->do_upload('File'.$i)) //File1,File2 are filenames
{
$img_data = $this->upload->data();
$images[$i] = $img_data['file_name'];
}
}
$data['Image'] = implode(',',$images);
$this->upload_model->upload_file($data);
at your model:
public function upload_file2($data)
{
$data = array('file_name' => $data['Image']);
$this->db->insert('images_table', $data);
}
That's it.If you want to retrive it from database use
$images = explode(',',$data->file_name);
it will give you an array of image names.
