Laravel 5 validate cloned fields using form request - php

Question

I have a form using cloneya jQuery plugin to clone form elements. The elements that will be cloned looks like so:
<div class="form-group">
<label for="name">Item name</label>
<input class="form-control" name="name[]" type="text">
</div>
<div class="form-group">
<label for="count">Item count</label>
<input class="form-control" name="count[]" type="text">
</div>
As you can see, each input will be an array instead of string. I want to validate those using Laravel Form Request. Here's my rules:
public function rules()
{
return [
'name' => 'required|between:3,50',
'count' => 'required|integer|min:1',
];
}
But that's not working. When I submitted the form, I got the following error message:
htmlentities() expects parameter 1 to be string, array given
I've been searching for solution, but can't find the appropriate one. Any suggestion would be appreciated!

Basically, in your rules() method, you need to determine how many name and count elements there are in the POST and then create rules for each of them:
public function rules()
{
$rules = [];
foreach ($this->request->get('name') as $index => $val) {
$rules['name.' . $index] = 'required|between:3,50';
}
foreach ($this->request->get('count') as $index => $val) {
$rules['count.' . $index] = 'required|integer|min:1';
}
return $rules;
}
