The code can upload picture from all field but it only resize the first picture.
Anyone can help me ?

Sorry for my bad English.

//set config for upload image

    $config['upload_path'] = './images/product/';

    $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';

    $config['encrypt_name'] = TRUE;

    //$config['quality'] = '80%'; 

    //$config['max_size'] = '100';

    //$config['max_width']  = '1024';

    //$config['max_height']  = '768';

    $this->load->library('upload', $config);

    //end set config

    for($i = 1; $i <= 10; $i ++)

    {

     if ( $_POST['checkP' . $i] != "" )

     {

      $field_name = "pPicture" . $i;

      if ( ! $this->upload->do_upload($field_name) )

      {

       $message = "Hình ảnh không đúng định dạng hoặc quá lớn";

      }

      else

      {

       $uploadData = $this->upload->data();

       //resize image

       $config['image_library'] = 'gd2';

       $config['source_image'] = $uploadData['full_path'];

       $config['width'] = 60;

       $config['height'] = 90;

       //$config['create_thumb'] = TRUE;

       //$config['maintain_ratio'] = TRUE;

       $config['new_image'] = './images/product_thumb/' . $uploadData['file_name'] ;

       $this->load->library('image_lib', $config);

       //end set thumbs config

       $this->image_lib->resize();

       $this->product_model->update_productpicture($idProduct, $i, $uploadData['file_name']);

      }

     }

    }

Hi Lamhuy,

try it this way - should work:

Code:
&lt;?php

function yourmethod(){

 // ... more of your code before

 $uploadData = $this->upload->data();

 // from here change code to

 $this->_resize_mood($uploadData);

 $this->product_model->update_productpicture($idProduct, $i, $uploadData['file_name']);

}

function _resize_mood($uploadData)

{

 $config['image_library'] = 'gd2';

 $config['source_image'] = $uploadData['full_path'].$uploadData['file_name'];

 $config['create_thumb'] = FALSE;

 $config['maintain_ratio'] = TRUE;

 $config['width'] = 60;

 $config['height'] = 90;

 $this->image_lib->clear();

 $this->image_lib->initialize($config);

 $this->image_lib->resize();

}

?&gt;

The important part is where you fire the clear function. I like tp put
such code into an extra function - you could copy that lines into your
upload method directly of course.

Code:
function _do_upload_file()

 {

     //upload path and config

  $config['upload_path']   = './assets/uploads/userfiles/';

     $config['allowed_types'] = 'png|jpg|gif|jpeg';

     $config['max_size'] = '3000';

     $this->load->library('upload', $config);

  $this->upload->initialize($config); 

     if (!$this->upload->do_upload())

     {

         $this->form_validation->set_message('_do_upload_file', $this->upload->display_errors());

         return FALSE;

     }

     else

   $filedata = $this->upload->data();

Quote:but what i want to do is resize it before it does any of that

On PHP base you can't resize the image before uploading
(if its that what you meant)

What you can do is something like that:

Code:
// return "$filedata" like you have it now instead of "TRUE"

// or set a class property like $this->filedata in your upload function and pass it

$filedata = $this->_do_upload_file(); 

when calling the resize function.

if ($filedata !== FALSE){

$this->_resize_mood($filedata); // see provided code a few posts ago and edit format

}

In case you have your "_do_upload_file" function as a callback
as a form-validation rule just set up a new callback function
and fire the upload and resize function inside the callback.
