fix to make it work with WPG2 plugin & other php-generated images calls.
-
Hello !
Maybe this isn’t perfect yet, but I made an update of the tb_post_thumb function of Post thumb.Using this, the plugin works with images insert into posts via URLS : for example; this
https://www.monsite.com/main.php?g2_view=core.DownloadItem&g2_itemId=38&g2_GALLERYSID=626998fb440fbf8ab52fdde92af223bbwould not work with the original function but works with this fix.
function tb_post_thumb($generate=false, $alt_text='', $resize_width = 0, $resize_height = 0, $crop_x = 0, $crop_y = 0) { global $post; $settings = get_option('post_thumbnail_settings'); // dir to save thumbnail to $save_dir = $dest_path['dirname']."/{$settings['folder_name']}"; //GALLERY2 MOD : this has been moved from above // find an image from your domain if (preg_match('/<img (.*?)src="https?:\/\/(www\.)?'.str_replace('/','\/',$settings['domain_name']).'\/(.*?)"/i',$post->post_content,$matches)) { // put matches into recognizable vars // fix later, assumes document root will match url structure $the_image = $settings['base_path'] . '/' . $matches[3]; ///GALLERY2 MOD - IMGS TAGS $the_image_url = $settings['full_domain_name'] .
