Welcome to WordPress SO. You may already have solved the issue as suggested by @Stevish, but just in order to avoid promoting the idea of checkboxes somehow being bad or difficult, I’d like to point out, that they’re perfectly okay and logical. 🙂 What is the problem in your first snippet, is the additional closing … Read more
There’s a few ways to achieve this but here’s one which supports an unknown depth of children, for example where you have nested groups within groups. Given the field key “field_{some_hash}” of the field, this function will retrieve the field, and its parent most field, and so on until we reach the top of the … Read more
IDs always show in links in admin area, like /wp-admin/post.php?post=2164&action=edit There are also some plugins that simplify this, quick search came up with Simply Show IDs.
you can do that with hooking a simple function to save_post hook add_action(‘save_post’,’my_rating_field’); function my_rating_field($post_id){ global $post; // verify if this is an auto save routine. // If it is our form has not been submitted, so we dont want to do anything if ( defined( ‘DOING_AUTOSAVE’ ) && DOING_AUTOSAVE ) return; // verify this … Read more
The reason why in the code, you show there, that delete_post_meta() is run first, is because add_post_meta() is run after it. If the delete wasn’t done first then you would end up with multiple entries stored in the meta table. To be honest it would be better to use update_post_meta() rather than both delete_post_meta() and … Read more
As simple as this: $the_posts_you_want = get_posts( array( ‘meta_key’ => ‘project_id’ ) ); foreach ( $the_posts_you_want as $post ) { // Do whatever you need in here… // Read further how to inspect the post object: http://wordpress.stackexchange.com/questions/13063/how-to-inspect-global-variables-in-wordpress // echo each meta key echo $post->whatever; // or save it into a new array for further processing … Read more
Short answer: NO! I’ve asked a similar question before mysql order by serialized data? and the answer i got is: The only possible case when serialized data is acceptable is when you don’t need to search , filter or order by through that data. In all other cases – store your data as a separated … Read more
I had trouble with a similar issue of sorting posts from a custom post type in a specified order on their archive page. I used http://wordpress.org/extend/plugins/sort-query-posts/. The plugin lets you sort posts by author, comment_count, date, id, menu_order, modified, parent, or title. It only requires you to add the following lines <?php query_posts(array(‘post_type’=>’post_type_name’, ‘posts_per_page’ => … Read more
So, I would refactor this a bit: <?php $featured = ( has_post_thumbnail() ? get_post_thumbnail() : false ); $first_img = false; $custom = false; if ( ! $featured ) { // No featured image; look for attached images and get the first one $attachments = get_children( ‘post_type=attachment&orderby=menu_order&post_mime_type=image&post_parent=”.$post->ID ); $first_img = ( $attachments ? wp_get_attachment_image_src($attachments[0]->ID, “thumbnail-size’) : … Read more
I can’t tell here whether or not you have the WordPress API available to you. (Is this code that is being run from within an instance of WordPress, or is it being run by an external script on the WordPress database, without bootstrapping WordPress itself?) If you have the WordPress API, it is easy to … Read more
