I have a custom post 'events'. For each post there is a gallery attached. On a main galley page i am displaying featured images from each post . Now i want that when person clicks on this featured image , he should be taken to a new template where images from the embedded gallery of the post are displayed using get_post_gallery(). I can't use permalink because it will take me to the 'single-event'.

How can i do it ? Please help me out.

  • You need to give more details. How is the gallery attached? What is get_post_gallery()? ...... – cybmeta Jul 29 '14 at 11:30
  • I attached the gallery using <add media> at the top of main content area . Then i created the the gallery. get_post_gallery is the method of getting the gallery of the current post i am using in single-events.php to get and display the gallery. Using get_post_gallery is not necessary if there is some another way. – terminator Jul 29 '14 at 11:40
  • I didn't know about get_post_gallery(), sorry, now I know what it is. So, the gallery is not attached, it is embeded. And what you need is a separate template to display the gallery embeded in the post? Am I right? – cybmeta Jul 29 '14 at 11:51
  • of course you are right . that is exactly what ii want to do – terminator Jul 29 '14 at 12:11
  • Any ideas how to do so – terminator Jul 29 '14 at 15:02

I think one good possibility is to add a endpoint to permalink for galleries and then check the template to include in the template_include filter:

add_action('init', function() {
    add_rewrite_endpoint( 'gallery', EP_PERMALINK );
});
add_filter( 'template_include', function($template) {
    if ( get_query_var( 'gallery' ) ) {
        return get_stylesheet_directory() . '/single-event-gallery.php';
    }
    return $template;
});

Now, create the file single-event-gallery.php and put it in your theme folder. You can copy the content of single-event.php and replace the_content() with:

if ( get_post_gallery() ) {
     echo get_post_gallery();
} else {
     echo "No gallery found";
}

You must use URLs like mysite.com/event/a-event-post/gallery/1 ("1" is a random value, any value after "gallery/1" is valid).

I tink it is a simple, fast and easy solution but with these problems:

  • It adds the endpoint rewrite rules to all permalinks
  • It needs some value after gallery in the URL

To avoid that problems we can define a custom rewrite rule only for "event" post type and define a custom query var to use in the template_include fiter.

add_action( 'init', 'cyb_event_gallery_rewrite_rule' );
function cyb_event_gallery_rewrite_rule() {
    add_rewrite_rule( '^event/([^/]+)/gallery/?$', 'index.php?event=$matches[1]&gallery=yes', 'top' );
}

add_filter( 'query_vars', 'cyb_register_gallery_query_var' );
function cyb_register_gallery_query_var( $vars ) {
    $vars[] = 'gallery';
    return $vars;
}

add_filter( 'template_include', function($template) {
    if ( get_query_var( 'gallery' ) ) {
        return get_stylesheet_directory() . '/single-event-gallery.php';
    }
    return $template;
});

Now you can use URL like mysite.com/event/a-event-post/gallery/. You can generate the URL inside the loop of parent post with (or similar, depends on your permalink settings):

$gallery_url = get_permalink() . 'gallery/';

Note: after you apply this code you need to flush the rewrite rules of your site. You can do that visiting the permalinks settings page and clicking in "save".

  • THANKS A LOT FOR HELPING ME OUT. BUT TH THING IS ITS GOING OVER MY HEAD. I copied all of the above code in functions.php What href="" do i need to give to the featured images on the gallery page – terminator Aug 1 '14 at 7:19
  • If you use the first way, you must use URL like mysite.com/event/a-event-post/gallery/1 (with some value after "gallery"). If you use the second way you can use mysite.com/event/a-event-post/gallery/ (without any value after "gallery"). And don't forget to flush the rewrite rules of your site. – cybmeta Aug 1 '14 at 9:22
  • I am using the second method.Now do i need to just add mysite.com/event/a-event-post/gallery/ to the href of feature images on gallery or page . – terminator Aug 1 '14 at 9:51
  • Yes, that is. And remember to create the single-event-gallery.php template file. If my answer fix your problem and help you, please mark it as accepted. Thank you. – cybmeta Aug 1 '14 at 12:24
  • i used href="localhost/basswaves/a-event-post/gallery" but it gives me error object not found. i created the single-events-gallery.php . 'events ' is the custom post – terminator Aug 4 '14 at 16:08
