Debugging in WordPress The following could/should be set in the wp-config.php file of your local(!!) installation – never do this on a live site, especially not when you got caching activated! define( ‘WP_CACHE’, false ); // Show the development files for scripts/stylesheets and don’t combine them define( ‘COMPRESS_CSS’, false ); define( ‘SCRIPT_DEBUG’, true ); define( … Read more
There were three issues: The first wasn’t visible in the code presented. a wp_register_styles call was put into the constructor, which caused errors and somehow prevented saving post metadata. Second, the date field was a HTML5 date field, which conflisted with jQuery’s datepicker. Changing it to a text field fixed that. Third, the final if … Read more
Ok, with the use of this ‘plugin’ (JareDatch). It works like a charm. add_filter( ‘cmb_meta_boxes’, ‘cmb_sample_metaboxes’ ); /** * Define the metabox and field configurations. ** @param array $meta_boxes * @return array */ function cmb_sample_metaboxes( array $meta_boxes ) { // Start with an underscore to hide fields from custom fields list $prefix = ‘_cmb_’; $meta_boxes[] … Read more
I would recommend executing two separate queries, each one differing from the other via a meta_query against your post custom meta key value. $current_query_args = array( ‘post_type’ => ‘recipient’, ‘meta_query’ => array( array( ‘key’ => ‘yes_current’, ‘value’ => ‘on’, ‘compare’ => ‘=’ ) ) ); $current_query = new WP_Query( $current_query_args ); if ( $current_query->have_posts() ) … Read more
I am not sure exactly what you are trying to ‘extend’, or how you want to extend it, but you can alter posts types with add_post_type_support, remove_post_type_support, and a few other functions. You can add metaboxes to the post type with add_meta_box setting the $post_type argument to the name used to register your post type. … Read more
Solution I created array outside the while loop and checked if the value is in array or not. <?php $args = array(‘post_type’ => ‘posttype’); $emptyvalue = “”; $optionname = “optionname”; $the_query = new WP_Query($args); $output =”<select name=””.$optionname.””> <option value=””.$emptyvalue.””>Location</option>'”; $arr = array(); while ( $the_query->have_posts() ) : $the_query->next_post(); $id= $the_query->post->ID; $location = get_post_meta($id, ‘institution_location’, true); … Read more
The problem was in how the the categories were stored in the array that didn’t go with the meta box code. To resolve the issue I’ve used a function (kindly provided by Jonathan Kuhn) that wrapped the categories in a way that I could use with the mate box code. Here’s the function: // Wrap … Read more
esc_url() is not a validator. Use PHP’s filter functions for that. Example: // $url is now an URL or FALSE $url = filter_var( ‘http://example.com’, FILTER_VALIDATE_URL ); if ( $url ) # update post meta else # delete post meta
It is probably here: if ( !wp_verify_nonce( $_POST[‘address_noncename’], plugin_basename(__FILE__) )) { return $post->ID; } You are using $_POST[‘address_noncename’] but aren’t checking to see if it exists before you do. That is going to trigger the warning you mentioned about an “undefined index”. If that warning prints to the screen before the headers are sent, you … Read more
You’ll need to use meta_query along with meta_(key|value|compare) to interact with two different keys and get the order you want. <?php $q = new WP_Query(array( ‘post_type’ => ‘my_project’, ‘nopaging’ => true, // same as posts_per_page => 1, ‘order’ => $order, ‘orderby’ => ‘is_featured_position’, // your position key here ‘meta_key’ => ‘is_featured_position’, // also here, see … Read more
