This works: $images = get_children( array( ‘post_parent’ => $post->ID, ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image’, ‘orderby’ => ‘menu_order’, ‘order’ => ‘ASC’, ‘numberposts’ => 999 )); if ( $images ) { $total_images = count( $images ); } The variable $total_images will hold the count of images in your gallery.
There are no filter hook called captiontag. You can change the value of the caption html tag by specifying the captiontag option when inserting the shortcode. From the gallery shortcode codex page: captiontag the name of the XHTML tag used to enclose each caption. The default is “dd”. For example, to change the gallery markup … Read more
You need to use the wp_enqueue_script function (in your functions.php file) to call the relevant scripts you need. It allows for both built-in libraries and to add any custom that you’re including in your theme.
This is actually quite easy: You just hijack the short code handler for image captions, grab the post_content (the image description) and set its content as a value for the attribute caption. Then you call the original shortcode handler. The following example requires the shortcode attribute desc set to 1 to make the magic work: … Read more
You can use javascript/jquery to solve this. When you insert a gallery in a wordpress posts, the whole gallery is wrapped by a div with id like “gallery-1” but also a class that’s always “gallery”. Also, every item is surrounded by two other “dl” and “dt”, with class “gallery-item” and “gallery-icon” respectively. So, you can … Read more
These functions will help: //function to get next or previous keys in an array function array_navigate($array, $key){ $keys = array_keys($array); $index = array_flip($keys); $return = array(); $return[‘prev’] = (isset($keys[$index[$key]-1])) ? $keys[$index[$key]-1] : end($keys); $return[‘next’] = (isset($keys[$index[$key]+1])) ? $keys[$index[$key]+1] : current($keys); return $return; } function previous_attachment_ID($att_post){ //get the attachments which share the same post parent $images … Read more
I’ve written answer to How to paginate attachments in a secondary query as gallery?, which can be used for solving this problem. Like @wpmudev-ari said the shortcode can be rewritten, or a new shortcode could be created. I explain below – B. – how this can be done. Additionally there is a very simple solution … Read more
If you’re working within a template file, this code should work. However, I didn’t test it. <?php echo do_shortcode(”); ?>
try : if (strpos($post->post_content,'[gallery’) === false){ $gallery = 0; }else{ $gallery = 1; }
Perhaps there’s a manageable way to shift the images from being store as attachments (aka posts) to being stored in an array that’s kept at the parent post level. I think it’s going to depend on how much you need to manipulate the images, delete them, etc. Shifting to another table might help but it … Read more
