The solution is to use a different hook which fires after post meta data has been saved by Gutenberg to the WP API. After reading this related discussion on Github and inspecting this code by n7studios, I discovered that rest_after_insert_post is a hook to use. So, the way to reliably check for the existence of … Read more
While you can do this with WP_Query, I’d do this the way you are trying to avoid– save a list in a separate key. The “pros” strongly outweigh the “cons” in my mind. LIKE queries with wildcards, especially with leading wildcards, are not efficient– aka, “slow” and a LIKE query on serialized data is going … Read more
I have found an answer at this article entitled “Excluding Categories from the_category();”: function the_category_filter($thelist,$separator=” “) { // list the IDs of the categories to exclude $exclude = array(4,5); // create an empty array $exclude2 = array(); // loop through the excluded IDs and get their actual names foreach($exclude as $c) { // store the … Read more
Use another custom field with the URL and call it something like leetpress_website_url then change your code to this: <?php if ( get_post_meta( $post->ID, “leetpress_website”, true ) ){ echo ‘<div class=”pros”><p><strong>Movie Website: </strong><a href=”‘ . get_post_meta( $post->ID, “leetpress_website_url”, true ).'”>’ . get_post_meta( $post->ID, “leetpress_website”, true ) . ‘</a></p></div>’; } ?>
You’re calling get_post_meta() in two different ways: the first, leaving $single unset (it defaults to false) will get you the full array of meta entries for the given key; the second, setting $single to true, will get only the first item with that key. What you want, I believe, is an array of user IDs … Read more
You don’t need to change any code. get_the_date without an argument will use the date_format option in your WordPress settings. The option F j, Y will substitute F as “September”, but if you have a translation of “September” it will be used. Comments have suggested the use of date_i18n. This is used automatically when you … Read more
wp_update_post isn’t used for updating custom fields (ie postmeta content) – you should use update_post_meta
From codex: $meta_value (mixed) (required) The value of the custom field you will add. An array will be serialized into a string. Default: None So <?php add_post_meta(7, ‘fruit’, ‘banana’, ‘apple’, ‘tornado’, ‘bob saget’) To grab them you can also use http://codex.wordpress.org/Function_Reference/get_post_custom_values besides just get_post_meta.
It’s unclear what the postmeta actually does so it could effect your website in any number of ways.At best it will just clear the field / option and the user will need to re-enter it for that specific page.At worst it could change a pages layout or orphan a media file in your media library … Read more
This question is off-topic because your is a simple PHP error, not related to WordPress. You are trying to check if a variable is empty using: if ( $meta != $empty ) { but this is not the right way, in fact this code compare the target variable $meta with another variable $empty that is … Read more
