$enddatevar = get_post_meta( $post_id, $key = ‘enddate’, $single = false); $post_id is not defined, either declare it beforehand, or use $post->ID. update_post_meta( $post->ID, ‘promote’, ‘$enddatevar’ ); ‘$enddatevar’ shouldnt be inside quotes.
Add a third parameter in the get_post_meta() function as true, that will return the single value of the current post meta, if you don’t set it it will return an array of the values. What is happening now is that internally the query is trying to compare the meta_value with an array instead of a … Read more
I don’t have a good way to query a title string to fill in the content You can use wp_get_document_title() to get the document title. So for example in your case: (see the docs for details on esc_attr()) <?php // Put the title (string) in a variable. $title_esc = esc_attr( wp_get_document_title() ); ?> <meta property=’og:title’ … Read more
If the data you placed at the beginning of your question is the result of your database query (I’m unsure by how your question is worded), you will want to take that query result and use the PHP function unserialize() to convert that data to an array, then you can access your data from that … Read more
No, it’s not possible to do this using the get_users function the way that you’ve outlined it, because get_users doesn’t accept a meta_query argument the same way that get_posts does. I see two approaches to get your desired result: either 1) get the users, then sort them afterwards, or 2) use $wpdb to write a … Read more
You are Storing multiple values into one single meta entry, instead of storing each value on its own meta entry (which would be the optimal approach). But still you can make it work that way. According to the docs, for the WP Query match operator you can use: Possible values are ‘=’, ‘!=’, ‘>’, ‘>=’, … Read more
There are lots of actions you can hook into to do this, I think the best once to use would be wp or template_redirect. Using either of those actions the code would be like this, this code goes into the functions.php add_action(‘wp’, ‘bt_update_user_homepage_meta’); function bt_update_user_homepage_meta () { // get user id, if user is not … Read more
Ok so we have things, and we want to favourite/unfavourite them as done. First, we need 2 functions: saeed_is_favourited( int $post_id, string $thing_to_favourite ) ( where $thing_to_favourite is the thing we’re marking as saved/favourited/etc, and $default is the value to return if we don’t know yet saeed_set_favourited( int $post_id, string $thing_to_favourite, bool $favourited ) where … Read more
What you get is fine, it’s the image id, now you just need to loop them and output the structure that you want, for example. if (!empty($images = get_comment_meta( $comment->comment_ID , ‘reviews-images’, true ))) { foreach ($images as $image_id) { $image_src = wp_get_attachment_image_src($image_id, ‘full’); // Now you have the image src, $image_src, you can do … Read more
you can also store it like yyyy-mm-dd and and use $date_array = explode( ‘-‘, $date_string ); to make it into an easy to manage array. or even better change it into a unix timestamp with $unix_time = strtotime( $date_string ); php loves to work with unix time stamps, it’s the native format. and when you’re … Read more
