我创建了一个带有自定义帖子选项的侧边栏框,但我似乎无法将其余的帖子数据保存到数据库中。

add_action('admin_menu', 'my_post_options_box');
function my_post_options_box() {
add_meta_box('post_info', 'Column Height Info', 'custom_post_info', 'post', 'side', 'high');
}
//Adds the actual option box
function custom_post_info() {

add_action('save_post', 'custom_add_save');
function custom_add_save($postID){
// called after a post or page is saved
if($parent_id = wp_is_post_revision($postID))
{
$postID = $parent_id;
}
if ($_POST['column_type']) {
update_custom_meta($postID, $_POST['column_type'], 'column_type');
}
if ($_POST['header_size']) {
update_custom_meta($postID, $_POST['header_size'], 'header_size');
}
}
function update_custom_meta($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);
}
}
?>
我手动将 column_type 和 header_size 添加到 post 表中,但数据没有进入数据库。帮助!!!
