I have a multiple file upload which sends an array of image files to Laravel. The images array can be accessed fine, but the validation rules I specified are always returning false because the value is an array, not a file.
I'm using a Request with a rules function, defined as:
public function rules()
{
$rules = [
'name' => 'required|max:500',
'code' => 'required|unique:products|max:500',
'description' => 'required',
'image' => 'image|max:4000',
];
return $rules;
}
I considered extending the validate function in Illuminate\Validation\Validator, but didn't have much luck (not really sure how to define it, tried a few different ways but always either got errors or it just didn't have any effect).
Can anyone suggest a way I can handle validation of an array of files globally, without having to do more manual validation by iterating my files.
public function rules()
{
$rules = [
'name' => 'required|max:500',
'code' => 'required|unique:products|max:500',
'description' => 'required'
];
$nbr = count($this->input('image')) - 1;
foreach(range(0, $nbr) as $index) {
$rules['image.' . $index] = 'image|max:4000';
}
return $rules;
}
@bestmomo Very elegant :) Thanks!
i know its kinda old post but doesn't the new 5.2 have a native .* to validate multiple inputs ? https://laravel.com/docs/5.2/validation#validating-arrays or is it different from the above approach ?
@ctf0 it does not work if you wish to validate the array value. I.e. you cannot do:
image.* => image
You have to do something like
image.*.file => image
@canfiax really !!! why in the gods name they don't include this in the docs ?!! , anyway i will test it today and get back to u, thanx for ur help :)
This thread has the answer - at least it works for me :) https://laracasts.com/discuss/channels/general-discussion/array-validation-is-not-working/
Specifically: this comment from @malhayek
@canfiax that didnt work, its as in the docs, simply image.*
will validate each item in the array but the error will always come back as required
@canflax Amazingly that worked! Thanks!
this code solved my problem for validating array of images. (name of image field in form is : file)
$request->validate([
'product_code' => 'required|string',
'product_name' => 'required|string',
'product_price' => 'required|string',
'file' => 'nullable', //name of image field in form
'file.*' => 'max:2048|image' //name of image field in form
]);
