How to check if request array is empty in laravel?
I have an input field in a form. Its is an array type. How can i check if the field is empty or not?
<td><input type="text" name="exam_name[]" placeholder="Exam Name" class="form-control name_list" /></td>
When i dd($request->exan_name) it shows null. But if i didn't gave any value to the field and submits, null value is inserting into database. How can i prevent it?

@MichalOravec When i run this code without any input, it shows "Field is not empty"
if($request->has('exam_name')) {
dd('field is not empty.');
} else {
dd('field is empty.');
}

@akhilmurali Then do
$request->validation([
'exam_name' => 'required|array',
'exam_name.*' => 'required|string',
]);
