Laravel: Form validation string-length error messages cause exception
提问by domwrap
When trying to implement Laravel's length based validation
尝试实现 Laravel 基于长度的验证时
'password' => array(
'required',
'alpha_dash',
'Min:7'
)
and outputting error messages in my view
并在我看来输出错误消息
{{
$errors->first(
'password',
'<span class="error">:message</span>'
)
}}
I get
我得到
Unhandled Exception
Message:
Array to string conversion
Location:
_avalog\laravel\messages.php on line 188
Stack Trace:
#0 _avalog\laravel\laravel.php(42): Laravel\Error::native(8, 'Array to string...', '_avalog...', 188)
#1 [internal function]: Laravel\{closure}(8, 'Array to string...', '_avalog...', 188, Array)
#2 _avalog\laravel\messages.php(188): str_replace(':message', Array, 'get('password', 'get()
Debugging, it appears to be true. If I print_r( $validation );
调试了一下，好像是真的。如果我print_r( $validation );
Laravel\Validator Object (
[attributes] => Array (
[username] => fred
[email] =>
[password] => asd
[csrf_token] => DWg3CUfqtMZkIRfyZXNEqygvWUHsGS9SQMue2V4S
)
[errors] => Laravel\Messages Object (
[messages] => Array (
[email] => Array (
[0] => The email field is required.
)
[password] => Array (
[0] => Array (
[numeric] => The password must be at least 7.
[file] => The password must be at least 7 kilobytes.
[string] => The password must be at least 7 characters.
)
)
)
[format] => :message
)
You can see that messages does in fact contain an array for password which appears to be dependent upon input type, even though I've specified in the rule it is alphadash
您可以看到消息实际上包含一个似乎取决于输入类型的密码数组，即使我在规则中指定它是 alphadash
[password] => Array (
[0] => Array (
[numeric] => The password must be at least 7.
[file] => The password must be at least 7 kilobytes.
[string] => The password must be at least 7 characters.
)
)
Whereas the rest, do not
而其余的，不要
[email] => Array (
[0] => The email format is invalid.
)
Looking at messages.phpin Laravel framework, it has nothing to handle such array-based messaging so I assume I am doing something wrong before it gets there, but I don't know what.
看着messages.php在Laravel框架，它没有任何处理这种基于阵列的消息，所以我认为我做的事情错了，它到那里之前，但我不知道是什么。
Thanks for your help.
谢谢你的帮助。

'password.min' => "Password can not be less than 6 characters.",
'password.min' => "密码不能少于 6 个字符。",
$custom_validation_messages = array(
'password.min' => "Password can not be less than 6 characters.",
'password.required' => "Password is required"
);
$validator = Validator::make($data, [
//'email' => ['required','unique:users,email','email','max:255'],
'email' => ['required','email','max:255'],
'password' => 'required|min:6|confirmed'
],$custom_validation_messages);
