Do I actually have to return $postID in each case, in the code below?
This is code required for capturing the values of custom fields I've added to the WP post and page editor. Got the idea from here: http://apartmentonesix.com/2009/03/creating-user-friendly-custom-fields-by-modifying-the-post-page/
add_action('save_post', 'custom_add_save');
function custom_add_save($postID){
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return $postID;
}
else
{
// called after a post or page is saved
if($parent_id = wp_is_post_revision($postID))
{
$postID = $parent_id;
}
if ($_POST['my_customHeader'])
{
update_custom_meta($postID, $_POST['my_customHeader'], 'my_customHeader');
}
else
{
update_custom_meta($postID, '', 'my_customHeader');
}
if ($_POST['my_customTitle'])
{
update_custom_meta($postID, $_POST['my_customTitle'], 'my_customTitle');
}
else
{
update_custom_meta($postID, '', 'my_customTitle');
}
}
return $postID; //IS THIS EVEN NECESSARY?
}
function update_custom_meta($postID, $newvalue, $field_name) {
// To create new meta
if(!get_post_meta($postID, $field_name)){
add_post_meta($postID, $field_name, $newvalue);
}else{
// or to update existing meta
update_post_meta($postID, $field_name, $newvalue);
}
}
