Image validation not working If using ajaxForm - validation

Question

I tried googling and saw other questions posted at this forum but could not find any solution for my issue. I am using Jquery ajaxForm method to submit form. My form contains one file field too in the form that can be used to upload a picture. I have defined the validation in my model. But the issue is even i am uploading a correct jpg file, still i am getting error message that
Argument 1 passed to Illuminate\\Validation\\Factory::make() must be of the type array, object given.
Javascript Code
$('#create_form').ajaxForm({
dataType:'JSON',
success: function(response){
alert(response);
}
}).submit();
Controllder Code
if ($file = Input::file('picture')) {
$validator = Validator::make($file, User::$file_rules);
if ($validator->fails()) {
$messages = $validator->messages();
foreach ($messages->all(':message') as $message) {
echo $message; exit;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
// do rest
}
}
Model Code
public static $file_rules = array(
'picture' => 'required|max:2048|mimes:jpeg,jpg,bmp,png,gif'
);
POST Request
I know that my validation defined in the model expects an array. But by passing $file in the validator, an object is passed. Then i changed the code like:
$validator = Validator::make(array('picture' => $file->getClientOriginalName()), User::$file_rules);
Now i am getting error:
The picture must be a file of type: jpg, JPEG, png,gif.

Answer 1

The problem is you pass file object directly to validate. Validator::make() method takes all four parameters as array. Moreover, you need to pass the whole file object as value so that Validator can validate mime type, size, etc. That's why your code should be like that.
$input = array('picture' => Input::file('picture'));
$validator = Validator::make($input, User::$file_rules);
if ($validator->fails()) {
$messages = $validator->messages();
foreach ($messages->all(':message') as $message) {
echo $message; exit;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
// do rest
}
Hope it will be useful for you.

Try rule like this.
$rules = array(
'picture' => 'image|mimes:jpeg,jpg,bmp,png,gif'
);
or try removing 'mimes'
