Depends what you are getting back from the ‘date_event’ post-meta field. That’s probably the culprit here — if it’s an actual date with a month and day, it’s not going to match what you are getting from date(‘Y’), which is just going to be ‘2018’. You can check the value in ‘date_event’ on any of … Read more
The add_post_metadata and update_post_metadata filters are meant to allow filtering whether a specific meta data should be saved (added/updated) or not, only. The default value (of $check) is a null, and if you return anything other than exactly null (i.e. !== null), the meta data will not be saved (into the database). However, the add_metadata() … Read more
As @Sally CJ noted in the comment to your question, you should just omit the meta key: $meta = get_post_meta( $post->ID, ”, true ); echo $meta[‘car_year’]; // 2005 In PHP 7.1 you can use array destructing: [ ‘image_meta’ => $image_meta, ‘car_year’ => $car_year, ‘car_mileage’ => $car_mileage, ‘car_price’ => $car_price, ‘car_model’ => $car_model, ] = get_post_meta( … Read more
Did you try something like this: $loop = new WP_Query( array( ‘post_type’ => ‘business_club’, ‘meta_value’ => ‘United Kingdom’, ‘order’ => ‘ASC’, ‘orderby’ => ‘meta_value’, ‘meta_key’ => ‘zone’ ) ); while ( $loop->have_posts() ) : $loop->the_post(); I don’t know yet if you can do the then orderby town and title.
Change your form as suggested: function startdate() { global $post; $custom = get_post_custom($post->ID); echo “<label>Startdates</label><br/>”; for ($i=0; $i<count($custom[“startdate”]);$i++) { echo “<input type=\”text\” name=\”startdate[“.$i.”]\” value=\””.$custom[“startdate”][$i].”\” />”; } } You’ll have to remove and reinstate your individual postmeta entries: add_action(‘save_post’, ‘save_details’); function save_details($post_id) { if ($parent_id = wp_is_post_revision($post_id)) $post_id = $parent_id; if (!empty($_POST[‘startdate’]) && is_array($_POST[‘startdate’])) { delete_post_meta($post_id, … Read more
Found the solution in this post: update_post_meta and update_field ony working when saving the post The solution is to use update_field because update_post_meta uses a different method to update fields than ACF does. Do note that this is the correct order of using the code update_field($meta_key, $meta_value, $post_ID);.
In my personal opinion, this can get a bit resource intensive, so you will need to implement some type of cache system, or even look at transient What you want to do is to extent your current post view function or even create one on the side for this. You would want to capture each … Read more
It looks like you need to use update_post_meta() https://codex.wordpress.org/Function_Reference/update_post_meta Source: WP Codex The function update_post_meta() updates the value of an existing meta key (custom field) for the specified post. This may be used in place of add_post_meta() function. The first thing this function will do is make sure that $meta_key already exists on $post_id. If … Read more
One call to get_post_meta() fetches all met keys and values for that post. All these values are then stored in the cache. The next call will just fetch the data from the cache. So you can safely call that function multiple times. In details: get_post_meta() calls get_metadata(‘post’, $post_id, $key, $single); get_metadata() checks the cache and … Read more
The get_post_meta() function can help to get the meta field but will not retrieve different size. Assuming _pf_photo1 embed the attachment id, you can do something like that: // Note the “_id” suffix $attachment_id = get_post_meta($post->ID, ‘_pf_photo1_id’, true); Last parameter for this function can not be ‘medium’, Now,you can use $attachment_id with different function depending … Read more
