我正在开发一个wp插件，它支持自定义帖子类型，因为我已经创建了一个metabox，一切都很顺利。当我在metabox字段中输入值时，它不会显示在管理面板中，因为它将存储在数据库中（wp\\U Posteta表）。有人能告诉我我的代码出了什么问题吗。
//Create Meta box
function astest_add_metabox(){
add_meta_box("astestimonial_metaboxes", "AS-Testimonial Client Information", "astestimonial_meta_box", "astestimonial", "side", "low");
}
add_action(\'add_meta_boxes\',\'astest_add_metabox\');
//html code
function astestimonial_meta_box($post_id){
wp_nonce_field(\'astest_meta_box\',\'astest_meta_box_nonce\');
$clientname = get_post_meta($post->ID,\'clientname_value\',\'true\');
echo\'<label for="client_name_val">\';
_e(\'Name: \', \'astestimonial_textdomain\');
echo\'</label>\';
echo\'<input type="text" id="clientname_value" name="clientname_value" value="\'.esc_attr($clientname).\'" />\';
//save post
function as_testi_save_data($post_id){
global $post;
if(isset($_POST[\'post_type\']) && ($_POST[\'post_type\'] == "astestimonial"))
{
$cli_name_data = $_POST[\'clientname_value\'];
update_post_meta($post_id, \'clientname_value\', $cli_name_data);
}
}
add_action("save_post", "as_testi_save_data");
有人能找出这有什么问题吗。。谢谢

您忘记申报全局$post
//Create Meta box
function astest_add_metabox() {
add_meta_box("astestimonial_metaboxes", "AS-Testimonial Client Information", "astestimonial_meta_box", "astestimonial", "side", "low");
}
add_action(\'add_meta_boxes\',\'astest_add_metabox\');
//html code
function astestimonial_meta_box() {
global $post;
wp_nonce_field(\'astest_meta_box\',\'astest_meta_box_nonce\');
$clientname = get_post_meta($post->ID,\'clientname_value\',true);
echo\'<label for="client_name_val">\';
_e(\'Name: \', \'astestimonial_textdomain\');
echo\'</label>\';
echo\'<input type="text" id="clientname_value" name="clientname_value" value="\'.esc_attr($clientname).\'" />\';
}
//save post
function as_testi_save_data($post_id){
if(isset($_POST[\'post_type\']) && ($_POST[\'post_type\'] == "astestimonial")) {
$cli_name_data = $_POST[\'clientname_value\'];
update_post_meta($post_id, \'clientname_value\', $cli_name_data);
}
}
add_action("save_post", "as_testi_save_data");
