I think I’d build that upon and already existing plugin that does the counting for me. I have made quite good experience with Post Views Counter as it also lets you use it in WP_Query. But WP-PostViews looks promising as well. Choose one. Next I’d query posts by view count from a WordPress cron event … Read more
‘meta_query’ is what you’re looking for: http://scribu.net/wordpress/advanced-metadata-queries.html
You can use update_post_meta() to save an array of values. It will be automatically serialized and unserialized. update_post_meta($post_id, ‘math’, array($a, $b, $c));
Have you checked the classes on your <body> element? It depends on the theme but WordPress has a function body_class() that dynamically adds a bunch of useful classes in there. It may look like this: <body class=”archive category category-news category-2 two-column content-sidebar”> As you can see it is a powerful helper as you can easily … Read more
$parent_post is an object, update_post_meta requires the ID, so should be: update_post_meta( $parent_post->ID, ‘average_wr’, $commentdata );
There may not be a need for a custom query, but I’d recommend it rather than hitting the database: – once for the WP_Query – once more for each post entry And then manually working out the math in PHP. Do it all at once with one MySQL statement. select sum(PM.meta_value) from wp_postmeta PM join … Read more
I assume you are trying to add metadata to the header, such as Open Graph. To do so, you can hook into wp_head and output your content there directly. Add this piece of code to your theme’s (or your child theme’s) functions.php file: //Hook to wp_head add_action(‘wp_head’,’add_my_metadata’); function add_my_metadata(){ // Echo any content your wish … Read more
get_post_meta takes 3 params, not two: get_post_meta( int $post_id, string $key = ”, bool $single = false ) As you can see, the third param is false by default. It means, that if you don’t pass it, the function will return an array with all custom fields for that key. If you have only one meta field with key prep_time, you’ll get: Array( … Read more
You shouldn’t change serialised PHP data structures directly. Serialised data contains the length of each value, and by changing a section of text, that length is no longer correct, and PHP runs into a fatal error and crashes. I don’t know what you are doing, but you should not modify serialised PHP strings manually.
This line is wrong: ‘meta_key’ => ‘adminscore’ + ‘user_like’ + ‘_count-views_all’ + ‘comment_count’, ‘meta_key’ only accepts string value. What you need is an additional meta key, e.g. “totalscore” that holds the total value of the scores you have for all the meta values. You can manually run a php function that calculates and store the … Read more
