Validate input file image array in laravel 4
提问by Diego Castro
I have a form like this that can have multiples images[] field:
我有一个这样的表单，可以有多个图像 [] 字段：
{{ Form::open(array('url' => 'foo/bar', 'files' => true)) }}
<input type="file" name="images[]">
{{ Form::close() }}
How can I validate this field with laravel 4 validation? I tried this rule but it didn't work:
如何使用 Laravel 4 验证来验证此字段？我试过这条规则，但没有奏效：
$rules = array('images[]' => 'required|image');

First of all are you running "images[]" over a loop? There is plenty of code examples for laravel 4 that actually don't work at all... And people who wrote them don't know how to use var_dump()...
首先，您是否在循环中运行“图像 []”？有很多 Laravel 4 的代码示例实际上根本不起作用......编写它们的人不知道如何使用 var_dump()......
If not - your probably running validation over a array of objects, try check:
如果不是 - 您可能正在对一组对象进行验证，请尝试检查：
var_dump(Input::file('files'));
So now after this lecture, lets run a for loop (had some issue with foreach idk why):
所以现在在本次讲座之后，让我们运行一个 for 循环（为什么 foreach idk 有一些问题）：
$files = Input::file('images');
$filesCount = count($files);
for ($i=0; $i < $filesCount; $i++)
{
$file = $files[$i];
$input = array(
'upload' => $files[$i]
);
$rules = array(
'upload' => 'image|max:15500'
);
$validation = Validator::make($input, $rules);
}
And now you can run your validation. Laravel4 only tries to valid mime type... so its vulnerable.
现在您可以运行您的验证。Laravel4 只尝试有效的 mime 类型......所以它很容易受到攻击。
