How to oEmbed from custom field, responsive to container size and responsive

I completed the task with fitvids.js by using the plugin FitVids for WordPress. Chris Coyier describes the integration with WordPress in his screencast Integrating FitVids.js into WordPress (on YouTube). My custom field name is video_url. I used the following code in my template: <?php if (!((get_post_meta($post->ID, ‘video_url’, TRUE))==”)) { echo wp_oembed_get( get_post_meta($post->ID, “video_url”, true) ); … Read more

Order by meta_value_num DESC and meta_value ASC on WP 4.0

I’ve went through a couple of scenarios and even went and digged into trac and make and came up with the following make.wordpress.org A more powerful orderby in wordpress 4.0 trac ticket #17065 None of the issues … Read more

Getting Bootstrap accordion working in WordPress loop with custom post type (collapsing issue)

Never mind I got it. I used <?php the_ID(); ?> to set unique id’s but even so that was not the problem. Turns out the first accordion had a class of “in” so the real question was How can I only give a class to the first post of a loop? and I did that … Read more

Multiple meta values for same meta_key adding on “Preview Changes” hit but not on saving or updating post

But I’d love to accept an answer more appropriate to the situation: After @ialocin’s suggestion, I got that, the $post_id wasn’t accurate … Read more

Detect meta value changes when post is updated (post_updated)

Like @SamuelElh comment this is how I solved it: add_action(‘updated_post_meta’, ‘check_meta_change’, 0, 4); function check_meta_change($meta_id, $post_id, $meta_key, $meta_value) { if( ‘<ENTER YOUR META KEY>’ == $meta_key ) { // do stuff } }

Need help adding custom field to category

Checkboxes are a bit different than text inputs. The main changes below are in the save function and with handling the checked attribute. The value of show_category will be yes if it’s been checked or an empty string for unchecked. Keep in mind that if the show_category meta was never saved it will be unset, … Read more

Get updated meta data after save_post hook

Apparently in order to get the meta value right after saving the post, you have to either get the $_REQUEST[‘my_meta_value’] directly, or, if you need to update the database right away, you have to use update_post_meta() in your save_post action.

How to make an meta_query optional?

It’s not so difficult. All you have to do is to add a condition and check if the book_id param is passed. You can even check if this param is correct (for example if the book_id should be a number, then you can check if it is): add_filter( ‘rest_gallery_query’, function( $args ) { if ( … Read more

ACF – get_field() using ‘option’ as post_id not working

I just had the same problem. It’s insanely poorly documented on ACF’s pages (as in, not there at all). The core of your problem is, that you have spaces in your options-page names. And when you access it, using the ‘ID’, then you have to use the ‘page_title’, but where all spaces are replaced by … Read more
