Question

I am pretty new to codeigniter and just building my first application with it, but I am abit stumped when it comes to generating a thumbnail from an image.

The image uploads correctly but the thumb isnt generating and I am getting no errors 🙁

I hope someone can give me a helping hand, chances are I am just being a tit and its something really simple like mis spelling var.

Heres the code for my image model:

<?php

class Image_model extends CI_Model {

        var $image_path;

        function Image_model(){

            parent::__construct();

            $this->image_path = realpath(APPPATH.'../'.$this->config->item('dir_dynamic_images'));

        }

        function do_upload(){

            $config = array(
                    'allowed_types' => "jpeg|gif|jpg|png",
                    'upload_path' => $this->image_path,
                    'max_size' => 2000
            );

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

            $this->upload->do_upload();
            $image_data = $this->upload->data();



            $config = array(
                'source_image' => $image_data['full_path'],
                'new_image' => $this->image_path . '/thumbs',
                'maintain_ratio' => true,
                'width' => 200,
                'height' => 200
            );

            echo $config['new_image'];

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

        }               

    }
?>

I think you need to set the create_thumb parameter to true and specify the image library-

 $config = array(
                'image_library' => 'gd2',
                'source_image' => $image_data['full_path'],
                'create_thumb' => true,
                'new_image' => $this->image_path . '/thumbs',
                'maintain_ratio' => true,
                'width' => 200,
                'height' => 200
            );

try finding the error with –

if(!$this->image_lib->resize()) 
{ 
   echo $this->image_lib->display_errors(); 
}
