edited June 2012 in Modules
I have 5 image upload fields. I am trying to resize all 5 images, at the moment when the script runs it will only resize one of the 5. Heres the code

function on_after_post($values)
{
$CI =& get_instance();
$CI->load->library('image_lib');

// create the thumbnail if an image is uploaded
if (!empty($CI->upload))
{
$data = $CI->upload->data();
if (!empty($data['full_path']))
{
$thumb_img300 = assets_server_path('prod/300/'.$this->thumb_name($data['file_name']), 'images');

// create thumb 300 height
$config = array();
$config['source_image'] = $data['full_path'];
$config['create_thumb'] = FALSE;
$config['new_image'] = $thumb_img300;
$config['width'] = 200;
$config['height'] = 300;
$config['master_dim'] = 'auto';
$config['maintain_ratio'] = TRUE;
//$CI->image_lib->clear();
$CI->image_lib->initialize($config);
if(!$this->image_lib->resize()) echo $this->image_lib->display_errors();
}

}
return $values;
}

    Is that the complete code?

    upload->data() gets you an array of information for a file, from the docs: This is a helper function that returns an array containing all of the data related to the file you uploaded.

    So it's per file, hence only saving one.

    So would you have to foreach the upload data? I have 5 upload fields

    If I use a multifile class on my image upload field, how can I access the path for each uploaded image inside my on_after_post hook for processing (using a loop, I guess)?

    There is a property set on the model called "upload_data" which contains an array of the uploaded data that you should be able to access from within your on_after_post hook
