想要用用户组合框值选择制作数组。

<?php

include_once $_SERVER['DOCUMENT_ROOT'].'/datacentre/admin/includes/db_connect.php';

class User {
	
	function getPermission( $email, $perms) {
	
		   if ($stmt = $mysqli->prepare("SELECT members.email , groups.permission FROM members 
		                                  JOIN groups ON members.group_id = groups.group_id 
										  WHERE email = ? LIMIT 1")) {
        $stmt->bind_param('s', $email);  // Bind "$email" to parameter.
        $stmt->execute();    // Execute the prepared query.
        $stmt->store_result();
        // get variables from result.
        $stmt->bind_result($user_email, $user_perms);
		print "yes we can ".$user_perms;
		exit();
		
		if($perms & $user_perms)
		{return true;
	      exit();}
	
	return false;
     exit();  
}
		
	}


?>

我想创建一个数组,使用Next_Click按钮参数逐步添加到数组。我卡住了,请帮助。 接收&#34;未处理的类型&#39; System.InvalidOperationException&#39;发生在WindowsBase.dll&#34;

我不明白你为什么这样做。 (奇怪的) 但问题可能是由于在将值设置为array [Step]之后未将gotResponse设置为false。
