No Need for SQL queries in the template. function wpse_72594_get_attachments( $id, $mime=”” ) { $args = array( ‘post_type’ => ‘attachment’, ‘post_mime_type’ => $mime, ‘post_parent’ => $id ); $attachments = get_posts($args); if ($attachments) return $attachments; return false; } Then call the function like this (300 is the post ID): wpse_72594_get_attachments(300), grabs all attachments wpse_72594_get_attachments(300, ‘image’ ), … Read more
In single.php i put this code, from this link (thank you Wyck) https://stackoverflow.com/questions/14277794/wordpress-3-5-own-gallery-with-included-images-doesnt-work preg_match(‘/\/’, $post_content, $ids); $array_id = explode(“,”, $ids[1]); print_r($array_id); Now I can use gallery shortcode
This may do.. [custom_gallery style=”1″ cat=”35″ link=”image” description=”0″ size=”200×200″ limit=”10″]
You are correct. The menu_order is no longer used for media in the gallery. Not sure if this is by design or an oversight. Could be by design since you can now include media in a gallery even if it is not “attached” to the page/post. In any case, below is the method I use … Read more
Image data is stored as if it were a post, or a CPT, so you can treat it like one. $album_id = get_the_id(); $img = new WP_Query(array(‘p’=>$album_id,’post_type’=>’attachment’)); var_dump($img->posts[0]->post_content); Or, a little more complicated,… $album_id = get_the_id(); $img = new WP_Query(array(‘p’=>$album_id,’post_type’=>’attachment’)); if (!empty($img->posts[0])) { var_dump($img->posts[0]->post_content); } get_the_ID will return the ID of the current post so … Read more
Your shortcode function callback must return the output, like this: function gamma_gallery( $attr ) { $html=””; // your stuff, where all the output is assigned to the $html variable return $html; } or you could try the output buffering: function gamma_gallery( $attr ) { $html=””; ob_start(); // your stuff $html = ob_get_contents(); ob_end_clean(); return $html; … Read more
You could use preg_replace() but I think it’s much easier to overwrite the $output via the post_gallery filter and then remove the filter after the first run: /** * Remove the output of the first gallery * * @param string $output * @param array $attr * @return string $output */ function wpse125903_remove_the_first_gallery( $output, $attr ) … Read more
I came across a solution for your functions.php from the following site that looks like it will do the trick. More detail on the implementation here: http://oikos.org.uk/2011/09/tech-notes-using-resized-images-in-wordpress-galleries-and-lightboxes/ Snippet below: function oikos_get_attachment_link_filter( $content, $post_id, $size, $permalink ) { // Only do this if we’re getting the file URL if (! $permalink) { // This returns an … Read more
You can use the same filter, just replace the type: add_filter(‘acf/update_value/type=gallery’, ‘my_acf_update_value’, 10, 3); All fields extend the same base class, so they also share the same basic filters.
You can override many of the Gallery Settings using the media_view_settings filter: /** /* Gallery Default Settings /* @param Array $settings /* @return Array $settings */ function theme_gallery_defaults( $settings ) { $settings[‘galleryDefaults’][‘columns’] = 5; return $settings; } add_filter( ‘media_view_settings’, ‘theme_gallery_defaults’ ); To change more settings, the easiest way is to use Developer Tools to inspect … Read more
