php - 循环遍历错误消息包，然后创建一个新数组

Question

我正在尝试遍历错误消息包 ($validator->errors()->getMessages()) 数组并将其对象推送到另一个数组 ($error)

$error = array();
$validator = Validator::make($request->all(),[
    'username' => 'required|unique:User',
    'password' => 'required',
    'fullname' => 'required|unique:Profile',
    'email' => 'required|email|unique:Profile'
]);

if($validator->fails()) :
    foreach($validator->errors()->getMessages() as $m => $key):
        array_push($error,$key);
    endforeach;
endif;

然后循环到新数组($error)并基于新数组对象($str)创建一个字符串

$str = '<ul class="c_red padding_zero margin_zero menu">';
foreach($error as $e ){ // this is the line 113
    $str.= '<li>'.$e.'</li>';
}
$str.='</ul>';

return array('success' => false,  'message' => $error );

但它返回一个错误

Array to string conversion line 113

这是不循环到 $error 数组以创建 $str 字符串时的响应

{"success":false,"message":[["The username field is required."],["The password > field is required."],["The fullname field is required."],["The email field is > required."]]}

错误中的每个键可能包含多个错误，因此它将是一个字符串...

所以你可以这样做:

if($validator->fails()) :
    foreach($validator->errors()->getMessages() as $validationErrors):
        if (is_array($validationErrors)) {
            foreach($validationErrors as $validationError):
                $error[] = $validationError;
            endforeach;
        } else {
            $error[] = $validationErrors;
        }
    endforeach;
endif;

在这里，您将获得所有错误消息的数组...
