I would like to know how I can determine if a post/page has an image gallery (not documents/videos etc)?
I am not talking about gallery shortcode as shown here Check if post/page has gallery?
so that
if (has_gallery = true){
//Do Something
}
else {
// Do Something else
}
You could use get_posts
and search for image attachments.
<?php
$images = get_posts(array(
'post_parent' => $the_parent_to_check, // whatever this is
'post_type' => 'attachment', // attachments
'post_mime_type' => 'image', // only image attachments
'post_status' => 'inherit', // attachments have this status
));
if($images)
{
// has images
}
else
{
// no images. :(
}
Might be more efficient to write a custom SQL query to check for the count. Depends on whether you want to do something with the attachment posts or not.
