If i create an array and convert it into JSON, will it be faster if i call 12 meta fields one by one or call the JSON, parse it and then have the variables? Virtually no difference. The meta API means that all meta keys/fields/values are pulled into memory from the database at most once … Read more
Are you outputting the saved data to the edit post page before saving the post? If not you may be getting a empty $_POST[‘collection-topics’] data and then saving empty or null data. I would do a check before doing add_post_meta() if ( empty($_POST[‘collection-topics’]) ) return;
If you want to fetch the data from a custom field named wpse_desc: then here’s one way to do that with your code snippet: function wpse_custom_meta_description() { // Nothing to do if ( ! is_single() ) return; // Fetch our custom field value $desc = get_post_meta( get_queried_object_id(), ‘wpse_desc’, true ); // Output if( ! empty( … Read more
Sometimes one just needs to ask to understand what the issue is. DELETE FROM `db_name`.`wp_postmeta` WHERE `wp_postmeta`. `meta_key` LIKE ‘_field_name[%]’ did the trick.
Sometimes when working with a larger block of HTML it is easier to just close your PHP tags and type the HTML directly instead of trying to echo your HTML within PHP. Yes, you should be able to echo your HTML as well. Edit: I want to take a closer look at the context from … Read more
You need to register your meta field first, then you can insert / update it into a post using rest api. https://codex.wordpress.org/Function_Reference/register_meta $object_type=”post”; $args1 = array( ‘type’ => ‘string’, ‘description’ => ‘My Meta Key Description’, ‘single’ => true, ‘show_in_rest’ => true, ); register_meta( $object_type, ‘MyMetaKey’, $args1 ); Hope it helps
There is a line in the code reference, which is used to save the meta values: $slug = “post”; if($slug != $post->post_type) { return $post_id; } This will simply end the function if you are not on a post. To allow saving data on a page, use this instead (remove the $slug): if(‘post’ != $post->post_type … Read more
Finally i got answer. post_type=event&meta_query%5B0%5D%5Bkey%5D=date_short_order&meta_query%5B0%5D%5Bvalue%5D=$today&meta_query%5B0%5D%5Bcompare%5D=%3C&meta_query%5B0%5D%5Btype%5D=DATE post_type=event&meta_query%5B0%5D%5Bkey%5D=date_short_order&meta_query%5B0%5D%5Bvalue%5D=$today&meta_query%5B0%5D%5Bcompare%5D=%3C&meta_query%5B0%5D%5Btype%5D=DATE
Creating a shortcode is fairly simple, it only needs a shortcode name and maybe some arguments. Here is a simple one for you: add_shortcode(‘my-shortcode’,’my_shortcode_function’); function my_shortcode_function(){ return ‘<div id=”search-nacionalidad”><p class=”‘. get_field(‘nacionalidad’).’ noselect” title=”‘.get_field(‘nacionalidad’).'” alt=”‘. get_field(‘nacionalidad’).'”>’.get_field(‘nacionalidad’).'</p></div>’; } Now, using [my-shortcode] exactly does what your code does. However I’m not sure how do you use this, whether … Read more
If you are storing your meta values as a single string separated by commas, you can use the native PHP explode() to store them in an array: $ct = get_post_meta($post->ID, ‘ct’, true); // Store them in an array $country_array = explode(‘,’ , $ct); // Run a loop and echo them foreach( $country_array as $key => … Read more
