如何在wordpress中将当前用户名插入数据库

Question

if(isset($_POST['submit'])){
$tablename = 'student_reg'; 
$data = array(
'user' => [$current_user],
'name' => $_POST['name'],
'age' => $_POST['age'],
'address' => $_POST['address'],
'telnumber' => $_POST['telnumber'],
'exam' => $_POST['exam'],
);
global $wpdb, $current_user;
$current_user = wp_get_current_user();
$current_username = $current_user->user_login;

$wpdb->insert($tablename, $data, $format=NULL);
}

我想将当前用户名插入数据库，但它不起作用。任何人都可以帮我解决这个问题。

在您的代码中引用变量的顺序存在问题。尝试将$current_user 和$current_username 添加到块的顶部，并删除'user' => [$current_username], 行中的方括号

if(isset($_POST['submit'])){
  global $wpdb;
  $current_user = wp_get_current_user();
  $current_username = $current_user->user_login;

  $tablename = 'student_reg'; 
  $data = array(
    'user' => $current_username,
    'name' => $_POST['name'],
    'age' => $_POST['age'],
    'address' => $_POST['address'],
    'telnumber' => $_POST['telnumber'],
    'exam' => $_POST['exam'],
  );

  $wpdb->insert($tablename, $data, $format=NULL);
}
