Your third parameter of get_post_meta() is set to false. This means it will return an array. Even though you didn’t set a value for this custom field, it will still record an array element in the DB – so empty() will return false. Try switching to true for your third param. That should return an … Read more
Technically, third party plugins are off-topic for this site. However this is an easy one – in the Custom Fields page in the admin area, go into your field group. Scroll right down to the bottom and there’s a section allowing you to “hide” elements in the post. Select the “content” option here and you’re … Read more
I would not use custom fields or shortcodes for this functionality, I would look at filters. the_content filter and the loop_end action (just make sure that your theme uses while ( have_posts() ) in single post pages) comes to immediate mind here. These are two options which requires no modification of any of your files … Read more
I just tested this and it works. <?php function toCall(){ global $wpdb; $togos = $wpdb->get_results(“SELECT * FROM $wpdb->postmeta WHERE meta_key=’_nelioefi_url'”); return $togos; } foreach (toCall() as $go) { global $wpdb; $wpdb->update( $wpdb->postmeta, array( ‘meta_key’ => ‘external_thumbnail’, // string // ‘column2’ => ‘value2’ // integer (number) ), array( ‘meta_id’ => $go->meta_id ) ); }; ?> You … Read more
Put simply, you don’t, and you shouldn’t The Problems Race Conditions Make the Data Super Unreliable Updating post meta, options, terms, etc is not an atomic operation. You need to fetch the view count, add 1 to it, then send it back to the database. During that process, another page load is occuring which does … Read more
You have created a custom field by altering the post table in the database. Custom fields in WordPress API are considered meta fields; such fields are stored in wp_postmeta table and that is the table used by functions like add_post_meta() and the rest of the functions and methods related with post custom/meta fields. You can … Read more
You need to use {old_status}to{new_status} hook. And use draft and publish statuses. This hook will only be executed when your post will change status from draft to publish. function wpse_288250_send_email( $post ) { $post_id = $post->ID; if( wp_is_post_revision( $post_id ) ) { return; } $post_url = get_permalink( $post_id ); $subject=”Your post is published!”; $message = … Read more
Neither option are the correct option for your use case Your question is barking up the wrong tree, because you neglected to mention that you intend to search for these posts based on the values the meta holds. If you’re displaying a post, you can use either method, though the first is cleaner/simpler to handle … Read more
The documentation for this is contradictory, but I believe wp_sitemeta is meant to only store information for sites in the wp_sites table, which only stores the main site in a network. It would make more sense to store each site’s template_color in their individual wp_[BLOGID]_options tables. However, keeping the data as-is, you may be able … Read more
Pages are posts, you just need to change the post_type to page: $args_automobile_just_launched_bike = array( ‘posts_per_page’ => 3, ‘post_type’ => ‘page’, ‘order’ => ‘DESC’, ‘meta_query’ => array( array( ‘key’ => ‘wpcf-new-launch-bikes’, ‘value’ => ‘1’, ), ), );
