If you want to and only need to do what @tf suggested, what is just to take care of displaying a 0 if no value is present, you can construct a function to do so like this: function wpse121165_return_carprice() { $ecpt_carprice = get_post_meta($post->ID, ‘ecpt_carprice’, true); if(! empty( $ecpt_carprice ) ){ return $ecpt_carprice; } else { … Read more
You’re right to use ‘save_post’ action hook. Try this: <?php add_action(‘save_post’, ‘some_function’); function some_function($post_id) { if(get_post_type($post_id) != “VA_LISTING_PTYPE”) return; $meta_value = get_post_meta( $post_id, ‘featured-cat’, true ); if($meta_value != 1) return; update_post_meta($post_id, ‘website’, ”); update_post_meta($post_id, ‘twitter’, ”); update_post_meta($post_id, ‘facebook’, ”); } if you’re on WordPress 3.7 or higher, you can use it this way: add_action(‘save_post_VA_LISTING_PTYPE’, ‘some_function’); … Read more
$response_radio = $_POST[‘meta-radio’]; if ($response_radio==”radio-one”) { //do your stuff } elseif ($response_radio==”radio-two”) { //do other stuff } I think this is what you are looking for
Perhaps using SQL statement? Direct SQL queries are very dangerous, especially when updating the DB. At the very least you will get any object cache out of sync and you might miss execution of import action and filters. If this update is something that is rarely done it is better that it will take one … Read more
I would strongly suggest to separate the products and not to put them all into one array. Or even to create a taxonomy companies, but this is more up to the while design and maybe a bad idea. Nevertheless this is a nice question to solve, so let’s play. So, the ‘prefix_products’ meta key is … Read more
ACF Upload Image in repeater from front-end with custom form? – add_post_meta()
Correct processing of `$_POST`, following WordPress Coding Standards
Lets break this down, Advanced Custom Fields (ACF) does save the data as custom field/post meta, I guess it seems all to obvious, but it is better to confirm it, and ElasticPress does set up custom fields automatically to include them into the search index. ElasticPress does this unless the meta data is hidden, which … Read more
If you want both posts that have and do not have a meta key, you need an OR relation meta query to select both posts with key and those where it does not exist. $args = array( ‘meta_query’ => array( ‘relation’ => ‘OR’, array( ‘key’ => ‘_post_like_count’, ‘compare’ => ‘EXISTS’ ), array( ‘key’ => ‘_post_like_count’, … Read more
Q1 Yes, you can store serialized arrays as a single meta key, eg: update_post_meta( $post_id, ‘my_items’, array( 1, 2, 3, 4 ); Furthermore, you can store multiple values against a single meta key, eg: add_post_meta( $post_id, ‘my_items’, 1 ); add_post_meta( $post_id, ‘my_items’, 2 ); The latter is preferred because meta queries can be more efficiently … Read more
