So I came back to this after practice and implemented some of the Alchemy setup, meaning all the inputs have names like name=”_movies[3]Metabox repeating fields – radio buttons not saving correctly” where 3 is the iteration we’re on in the loop. Create the Metabox // metaboxes should be registered on the add_meta_boxes hook add_action(‘add_meta_boxes’, ‘add_meta_boxes’ … Read more
You are using get_option() wrong, first variant, so take another look at the get_option() documentation. Basically you can’t directly access an array element with the function, it just doesn’t support it. The second variant should be possible, but you need at least PHP 5.4 – if I’m not totally mistaken; I don’t know anything about … Read more
I’m not sure you understand the logic of WP_Query. Rather than explain in words, here’s a code example; $query = new WP_Query( array( ‘meta_key’ => ‘Old ID’, ‘meta_value’ => $atts[‘oldid’] ) ); if ( $query->have_posts() ) return $query->posts[0]->post_title; return ”; Check out the codex on interacting with WP_Query. UPDATE: To use the query as you … Read more
When multiple meta values are used for same meta key, WordPress store the values in different database rows. So every array, is stored in one row. Initial Data Let’s assume you have an array like this: $family = [ ‘father’ => [ ‘John’, ‘Doe’, 40 ], ‘mother’ => [ ‘Jane’, ‘White’, 39 ], ‘child_1’ => … Read more
You can use get_the_title() to return the current post title in the loop.
Using get_sites() in WP 4.6+ It looks like wp_get_sites() will be deprecated in WP 4.6. The new replacement is: function get_sites( $args = array() ) { $query = new WP_Site_Query(); return $query->query( $args ); } Very similar to get_posts() and WP_Query. It supports various useful parameters and filters. Here’s what the inline documentation says about … Read more
This is a stupendously expensive query, you can mitigate but you can’t eliminate the performance issues. So lets start with the low hanging fruit and work our way up to the big problems posts_per_page Always set a maximum, even if it’s one you never expect to reach. -1 is asking for trouble: There’s no upper … Read more
I figured out what I was doing wrong. A simple beginners mistake. Array_reverse was working properly, but I wasn’t then reassigning the reversed array back to the $home_shows WP_Query, hence not seeing any change. Here is the answer, and my revised code. <?php $args = array( ‘post_type’ => ‘show’, ‘posts_per_page’ => 5, ‘order’ => ‘DESC’, … Read more
Normally you would just specify a meta_value, e.g.: $args = array( ‘post_type’ => ‘business’, ‘meta_query’ => array( array( ‘key’ => ‘specials’, ‘value’ => ‘these are not the specials you are looking for – Obi Wan Kenobi’ ) ) ); However because your post meta is actually a data structure, a serialised PHP array/object, that’s not … Read more
@EAMann’s answer is correct, but there’s already a build in WordPress function for fetching all registered post types: get_post_types <?php // hook into init late, so everything is registered // you can also use get_post_types where ever. Any time after init is usually fine. add_action( ‘init’, ‘wpse34410_init’, 0, 99 ); function wpse34410_init() { $types = … Read more
