Trying to put info from files into database

Does $file contain the the path or just the file name ?
Get_file_info need the path as well as the file name.
You might be better of using just the file helper.

PHP Code:

$this->load->helper('file');
    
    $files = get_filenames('./images/gallery/',TRUE); //TRUE to include the path with the file name
    
    foreach($files as $file) {
        
        $get_info = get_file_info($file);
        
        $data = array( 
            'category' => 'uncategorised',
            'image_name' => $get_info['name'],
            'alt' => $get_info['name'],
            'full_path' => $get_info['server_path'],
            'image_width' => '800',
            'image_height' => '600'
        );
        $this->add_content($data, 'gallery_images'); 


But I am not sure if this will include sub-folder. you will need to do a var_dump be sure.
Have a look at the helpers documentation to see what is available.

A good decision is based on knowledge and not on numbers. - Plato
