Laravel validation not showing errors
提问by markstewie
This is probably a simple fix... but I can't get validation to work.
这可能是一个简单的修复......但我无法验证工作。
I've simplified my test back to this...
我已经将我的测试简化为这个......
$input = array(
'name' => ''
);
$rules = array(
'name' => 'required|min:3|max:50|alpha'
);
$v = Validator::make($input, $rules);
And even though 'name' is required and has all the other rules the validator doesn't contain any errors.
即使“名称”是必需的并且具有所有其他规则，验证器也不包含任何错误。
dd($v->errors); // returns NULL
However
然而
dd($v->fails()); // returns bool(true)
Why are there no error messages? When I dump the whole $v object there are no messages to be seen anywhere. Very confused... help appreciated. Thanks.
为什么没有错误信息？当我转储整个 $v 对象时，在任何地方都看不到任何消息。非常困惑...帮助表示赞赏。谢谢。

I've simplified this even further. I've put this directly in a view to test...
我已经进一步简化了这一点。我已经把它直接放在一个视图中来测试......
<?php
$input = array(
'name' => ''
);
$rules = array(
'name' => 'required'
);
$v = Validator::make($input, $rules);
dd($v);
?>
I still get exactly the same problem?
我仍然遇到完全相同的问题？
Here is the $v object
这是 $v 对象
object(Laravel\Validator)#32 (9) {
["attributes"]=>
array(1) {
["name"]=>
string(0) ""
}
["errors"]=>
NULL
["rules":protected]=>
array(1) {
["name"]=>
array(1) {
[0]=>
string(8) "required"
}
}
["messages":protected]=>
array(0) {
}
["db":protected]=>
NULL
["bundle":protected]=>
string(11) "application"
["language":protected]=>
NULL
["size_rules":protected]=>
array(4) {
[0]=>
string(4) "size"
[1]=>
string(7) "between"
[2]=>
string(3) "min"
[3]=>
string(3) "max"
}
["numeric_rules":protected]=>
array(2) {
[0]=>
string(7) "numeric"
[1]=>
string(7) "integer"
}
}
Is something in my installation/setup broken?
我的安装/设置中有什么问题吗？

You have to test your Validator before there are any errors. Try this:
您必须在出现任何错误之前测试您的验证器。尝试这个：
if ($v->fails()) {
dd($v->errors);
}
回答by Andrew
I think you need to call $v->passesor $v->failsfirst, for it to actually evaluate your validation rules and generate errors. Then you can use...
我认为您需要先调用$v->passes或$v->fails，以便它实际评估您的验证规则并生成错误。然后就可以用...
dd($v->errors->all());
