This isn’t a WP question, but moreso a general form issue. Regardless, a checkbox will not pass anything if unchecked, and 1 or on if checked. // Sanitize user input. $my_data = $_POST[‘home_slider_display’] ? true : false; // Update the meta field in the database. update_post_meta( $post_id, ‘home_slider_display’, $my_data );
When in doubt use the API. Let’s say the structure of $wp_meta_boxes will change or go away one day. remove_meta_box() will still work, because the API is a contract between core and developers. Unsetting some keys in a global variable might break. unset() is easier to write when you want to remove a whole group: … Read more
Try Fieldmanager. It was built with repeating groups being priority #1. Your new code would look something like this: add_action( ‘init’, function() { $fm = new Fieldmanager_Group( array( ‘name’ => ‘artists’, ‘limit’ => 0, ‘label’ => ‘New Artist’, ‘label_macro’ => array( ‘Artist: %s’, ‘name’ ), ‘add_more_label’ => ‘Add another Artist’, ‘children’ => array( ‘name’ => … Read more
As Apple might’ve put it “There’s a plugin for that” 🙂 (Faster Image Insert)
<?php $meta = get_post_meta( $post->ID, ‘Meta’, true ); $lan = qtrans_getLanguage(); $meta_lan = qtrans_use( $lan, $meta, true ); echo $meta_lan; ?> then enter your custom field data using the qtranslate comments: <!–:ca–>CA<!–:–><!–:es–>ES<!–:–><!–:en–>EN<!–:–>
Just add the class to the markup you are generating in the callback.
You cannot use a real metabox to do that, hook into edit_form_after_title instead. Here is a simple example: add_action( ‘edit_form_after_title’, ‘wpse_87478_pseudo_metabox’ ); add_action( ‘save_post’, ‘wpse_87478_save_metabox’ ); function wpse_87478_pseudo_metabox() { global $post; $key = ‘_wpse_87478’; if ( empty ( $post ) || ‘post’ !== get_post_type( $GLOBALS[‘post’] ) ) return; if ( ! $content = get_post_meta( $post->ID, … Read more
Define an array of post types, and register the metabox for each one separately: function add_custom_meta_box() { $post_types = array ( ‘post’, ‘page’, ‘event’ ); foreach( $post_types as $post_type ) { add_meta_box( ‘custom_meta_box’, // $id ‘Custom Meta Box’, // $title ‘show_custom_meta_box’, // $callback $post_type, ‘normal’, // $context ‘high’ // $priority ); } }
Yes, it is possible to limit the drag and drop functionality of your boxes. All one needs to do is find the right selectors for the specific boxes it wants to target. When you use $(“.meta-box-sortables”).[…] you are targeting all elements in the page with the class of meta-box-sortables. If, however, you add a custom … Read more
Users can drag and drop meta boxes and WordPress will save the order. So, in a sense, the order in which they were originally rendered does not matter. You know which one comes first because when you call add_meta_box it simply pushes your meta box’s args onto a global array called $wp_meta_boxes. Whichever call to … Read more
