我有一个不断重复的验证问题

Question

我正在尝试验证一个名称，确保该名称不被使用，但由于某种原因，验证错误一直在重复它，我希望它在用户使用之前显示“名称已经在使用“但我得到的这个名字已经在usename中已经在usename中已经在usename中已经在usename中已经在usename中已经在使用中”。我怎么能阻止它？

    $types = array();
$result = mysql_query("SELECT * FROM `im_album` WHERE username = '".$user_data['username']."'  ");

while(($row =  mysql_fetch_assoc($result))) {
    $types[] = $row['name'];
}
if (isset($_POST['img_album'])) {
       $al_name = $_POST['name'];
       $al_description = $_POST['description'];
       $mode = $_POST['mode'];

       if(empty($al_name)){
           $errors[] = 'album name required';
           }

        if (strlen($al_name) > 55 || strlen($al_name) > 255) {
            $errors[] = 'name fields are to long ';

        }
        foreach($types  as $album){
            if ($al_name == $album) 
             $errors[] = "name already in use";

        }};
        echo output_errors($errors);

Answer 1

foreach($types  as $album){
        if ($al_name == $album) {
           $errors[] = "name already in use";
           break;
        }
}

尝试这段代码，而不是那里的代码。
