If you are referring to the shortcode, then you can use the get_post_gallery() or get_post_galleries() function to retrieve the gallery data such as ids (a list of IDs separated with comma) and src (an array of image URLs). Sample code #1: (using get_post_gallery()) 1234 is the ID of the post containing the shortcode. $galry = … Read more
It isn’t documented but if we take a look to the gallery block, we see it passes an extra prop to the MediaUpload component. Try to pass gallery as well as multiple to the component.
Have you added any images to the page in which you are using the gallery? The shortcode won’t work without there actually being attachments on said post.
I would go with Categories + Posts, if there’s no data in-between that gets in the way.
For simple galleries, I usually code something up using Magic Fields. It gives the client an easy to use interface for adding images via the media library, with drag-and-drop reordering. Then I’ll use a jQuery slider on the front-end, or I’ll write my own.
You would have to create custom templates, but your reference page is fully achievable using the NextGen Gallery plugin.
Put this code in your functions.php and check. function custom_gallery( $output, $attr ){ global $post, $wp_locale; static $instance = 0; $instance++; // We’re trusting author input, so let’s at least make sure it looks like a valid orderby statement if ( isset( $attr[‘orderby’] ) ) { $attr[‘orderby’] = sanitize_sql_orderby( $attr[‘orderby’] ); if ( !$attr[‘orderby’] ) … Read more
You can get the attached media to a post using get_children. IE: get the first attached image for post ID == 14 $args = array( ‘post_mime_type’ => ‘image’, ‘numberposts’ => 1, ‘post_parent’ => 14, ‘post_type’ => ‘attachment’ ); $first_attached_image = get_children( $args );
Okay, I had the same problem and just solved it by adding an “exclude” field to the shortcode. Like so… You have to just pull the ID number of the file you don’t want to show. This works without adding any functions or edits to the theme.
Like always is WordPress, there is a filter to do this, without the need of a regular expression, that might fail if anything changes. Here is the code for the output: <?php add_filter(‘wp_get_attachment_image_attributes’, function($attr, $attachment){ unset($attr[‘alt’]); // Just deleting the alt attr return $attr; }, 10, 2); $url = wp_get_attachment_url( $attachment->ID ); $name = esc_attr( … Read more
