我试图在这种情况下获得用户metada我将在WP_List_Table
类中找到用户名或用户名或姓。由于我有一个名为users_id
的字段,我存储wp_users.ID
值,然后我在函数get_sql_results()
中执行了此操作:
private function get_sql_results()
{
global $wpdb;
$search = ( isset($_REQUEST['s']) ) ? $_REQUEST['s'] : false;
$do_search = ( $search ) ? " WHERE firstname LIKE '%$search%' OR lastname LIKE '%$search%' OR foid LIKE '%$search%' OR no_frequent LIKE '%$search%' " : '';
$args = array('id', 'firstname', 'lastname', 'foid', 'no_frequent', 'users_id', 'create_time');
$sql_select = implode(', ', $args);
$sql_results = $wpdb->get_results("SELECT " . $sql_select . " FROM " . $wpdb->prefix . "ftraveler $do_search ORDER BY $this->orderby $this->order ");
return $sql_results;
}
所以我到达users_id
。然后在函数get_columns()
中,我显示如下值:
public function get_columns()
{
$columns = array(
'id' => __('ID'),
'users_id' => __('WP User'),
'firstname' => __('Firstname'),
'lastname' => __('Lastname'),
'foid' => __('Passport'),
'no_frequent' => __('Frequent No'),
'create_time' => __('Created on')
);
return $columns;
}
但是,当我显示用户名或名字或姓氏时,显示用户ID,我怀疑的地方,我如何使用get_user_metadata($user_id)
函数得到值并显示在结果表中?< / p>
答案 0 :(得分:1)
您必须迭代$sql_results
并使用自定义users_id
替换get_user_metadata($users_id)
。类似的东西:
foreach( $sql_results as $key => $value ) {
$new_value = do_something_with( get_user_metadata( $value->users_id ) );
$sql_results[$key]->users_id = $new_value;
}
return $sql_results;
