Laravel:表单验证字符串长度错误消息导致异常

Question

在尝试实现基于Laravel长度的验证时

'password' => array(
    'required',
    'alpha_dash',
    'Min:7'
)

并在我的视图中输出错误消息

{{
    $errors->first(
        'password',
        '<span class="error">:message</span>'
    )
}}

我明白了

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()

调试,似乎是真的.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
)

你可以看到消息实际上包含一个密码数组,它似乎依赖于输入类型,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.
    )
)

而其余的,不要

[email] => Array (
    [0] => The email format is invalid.
)

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.

谢谢你的帮助.

您的规则条目有误.它必须是

'password' => 'required|alpha_dash|min:7'
