Solution 2
As Muhammad Yasin said there are plugins I'd recommend:
http://wordpress.org/extend/plugins/more-fields/
if you want to do it yourself in code look at: add_meta_box
<?php add_meta_box( $id, $title, $callback, $post_type, $context, $priority, $callback_args ); ?>
You can register boxes per post type.
Solution 3
If you want to create a custom meta box inside a custom post type you will need to use 3 functions.
A function to create a custom "meta boxes" block/screen on your post edit screen:
add_meta_boxes_{$post_type}
A function to add a input field to change/show your custom meta
And finally a function to save your meta along with the rest of the post when you click save on the post edit screen:
save_post_{$post->post_type}
In your case, a custom checkbox would look like this:
add_action( 'add_meta_boxes_products', 'meta_box_for_products' );
function meta_box_for_products( $post ){
add_meta_box( 'my_meta_box_custom_id', __( 'Additional info', 'textdomain' ), 'my_custom_meta_box_html_output', 'products', 'normal', 'low' );
}
function my_custom_meta_box_html_output( $post ) {
wp_nonce_field( basename( __FILE__ ), 'my_custom_meta_box_nonce' ); //used later for security
echo '<p><input type="checkbox" name="is_this_featured" value="checked" '.get_post_meta($post->ID, 'team_member_title', true).'/><label for="is_this_featured">'.__('Featured Product?', 'textdomain').'</label></p>';
}
add_action( 'save_post_team_member', 'team_member_save_meta_boxes_data', 10, 2 );
function team_member_save_meta_boxes_data( $post_id ){
// check for nonce to top xss
if ( !isset( $_POST['my_custom_meta_box_nonce'] ) || !wp_verify_nonce( $_POST['my_custom_meta_box_nonce'], basename( __FILE__ ) ) ){
return;
}
// check for correct user capabilities - stop internal xss from customers
if ( ! current_user_can( 'edit_post', $post_id ) ){
return;
}
// update fields
if ( isset( $_REQUEST['is_this_featured'] ) ) {
update_post_meta( $post_id, 'is_this_featured', sanitize_text_field( $_POST['is_this_featured'] ) );
}
}

Good morning.
I have created a custom post type called 'Products'. I want to create a custom field (is metabox the correct term?) where my client can tick a box to determine whether a given post within this CPT is a featured post.
Here is the code in my functions.php to create the 'Products' CPT:
function products_custom_init() { $labels = array( 'name' => _x('Products', 'post type general name'), 'singular_name' => _x('Product', 'post type singular name'), 'add_new' => _x('Add New', 'products'), 'add_new_item' => __('Add New Product'), 'edit_item' => __('Edit Product'), 'new_item' => __('New Product'), 'view_item' => __('View Product'), 'search_items' => __('Search Products'), 'not_found' => __('Nothing found'), 'not_found_in_trash' => __('Nothing found in Trash'), 'parent_item_colon' => '' ); $args = array( 'labels' => $labels, 'public' => true, 'publicly_queryable' => true, 'show_ui' => true, 'show_in_menu' => true, 'show_in_nav_menus' => false, 'query_var' => true, 'rewrite' => array('slug','pages'), 'capability_type' => 'post', 'hierarchical' => true, 'menu_position' => 5, 'supports' => array('title','editor','thumbnail','excerpt',) ); register_post_type( 'products' , $args ); } add_action( 'init', 'products_custom_init' );
So how do I add the 'featured' metabox / custom field to only Products posts?
Many thanks,
Cynthia
