Edit – This answer is no longer accurate for the current version of ACF, see their documentation Use the acf_save_post hook. function my_acf_save_post( $post_id ) { // vars $fields = false; // load from post if( isset($_POST[‘fields’]) ) { $fields = $_POST[‘fields’]; } // … } // run before ACF saves the $_POST[‘fields’] data add_action(‘acf_save_post’, … Read more
That’s because ‘meta_key’ and ‘meta_value’ are not public query vars. In other words, you can’t use them in URLs directly, nor should you. Instead, register a specific query var, like so: function register_my_qv() { global $wp; $wp->add_query_var( ‘my_qv’ ); } add_action( ‘init’, ‘register_my_qv’ ); Then, you can go to a URL like this: ?my_qv=foobar All … Read more
I would simply filter the_title so that it outputs the appropriate custom-field data for your custom post type: <?php function theme_slug_filter_the_title( $title ) { global $post; if ( ’employee’ == get_post_type( $post ) ) { $custom = ( get_post_custom( $post->ID ) ? get_post_custom( $post->ID ) : false ); $custom_title = ( isset( $custom[‘name’][0] ) ? … Read more
that could be caused by post revision being saved, and you should use wp_insert_post_data anytime you want to do something before the post is saved, here is an example plugin i just cooked up to test it and it looks like this: <?php /* Plugin Name: wpse37901 Plugin URI: http://en.bainternet.info Description: answer to http://wordpress.stackexchange.com/questions/37901/save-both-current-and-new-version-of-post-meta Version: … Read more
Edited again to demonstrate adding and removing filters: Include these general functions in your functions.php. These are the filters you will invoke for the loops where you want to limit your query by these two meta values: function date_check_join( $join ) { global $wpdb; $join .= ” JOIN “.$wpdb->postmeta.” AS startdate ON (“.$wpdb->posts.”.ID = startdate.post_id … Read more
First, just pass your arguments to the constructor of WP_Query as this is both cleaner, and the way you’re supposed to do it according to the Codex documentation of the class. You should be constructing things like this: $my_key_query_args = array( ‘post_type’ => ‘attachment’, ‘post_status’ => ‘inherit’, ‘meta_query’ => array( array( ‘key’ => ‘my_key’, ‘value’ … Read more
Change your nonce verify to actually verify and update post meta, else do nothing. But don’t use exit at the top of your template. // top of page if ( isset( $_POST[‘drw_inventory’] ) && wp_verify_nonce($_POST[‘drw_inventory’],’update_drw_postmeta’) ) { //if nonce check succeeds. global $post; $postid = $post->ID; $data = $_POST[‘priceone’]; update_post_meta($postid,’metakey’,$data); } // in single.php $priceone … Read more
Just do a query with WP_Query using the Custom Field parameters (meta_query) to look for posts with the meta key and the value – exemplary code: // args to query for your key $args = array( ‘post_type’ => ‘your_post_type’, ‘meta_query’ => array( array( ‘key’ => ‘videoid’, ‘value’ => $new_posts_videoid // for example: ‘111’ ) ), … Read more
The short answer: you need to modify the query for your single event post to include the metadata, so only posts with matching name, year, and month will be returned. I’ll show you the complete code I used to test this. I made a few changes to your code and simplified a few things, so … Read more
When you save an array as post meta, WordPress will serialize it to a string and save that string. Let’s take a simple array: array ( 1 => array ( ‘url’ => “https://wordpress.stackexchange.com/”, ‘title’ => ‘Home’ ), 3 => array ( ‘url’ => ‘http://wordpress.stackexchange.com/’, ‘title’ => ‘WordPress Stack Exchange’ ), 4 => array ( ‘url’ … Read more
