Stop user from deleting a set file name not working

After some more thinking about it I have got it all most working now.

In my foreach loop I have done a check like below.

if ($this->config->item('image_path') . $path == $no_image_check) {

PHP Code:

   public function delete() {
        $json = array();

        if (!$json) {

            $no_image_check = $this->config->item('image_path') . 'catalog/no_image.jpg';

            foreach ($this->input->post('path') as $path) {

                if ($this->config->item('image_path') . $path == $no_image_check) {

                    $json['error'] = 'Your Selected File Can\'t be removed!';

                } else {

                    if (is_dir($this->config->item('image_path') . $path)) {

                        rmdir($this->config->item('image_path') . $path);
                        rmdir($this->config->item('image_cache_path') . $path);

                        $json['success'] = 'Your Selected Folder Has Been Removed!';

                    } elseif (is_file($this->config->item('image_path') . $path)) {

                        unlink($this->config->item('image_path') . $path);
                        unlink($this->config->item('image_cache_path') . $path);

                        $json['success'] = 'Your Selected File Has Been Removed!';

                    }
                }
                
            }
            
        }

    $this->output->set_content_type('Content-Type: application/json');
   $this->output->set_output(json_encode($json));

} 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
