Laravel validation for Array not working

Question

I have the following naming conventions for input fields.

course_details[0][d_Total_Score]
course_details[1][d_Total_Score]
course_details[2][d_Total_Score]

Now I want to validate these fields with some rules. The following is the code I tried.

$validatedData = $request->validate([
    'course_details.0.d_Total_Score' => 'required',
    'course_details.1.d_Total_Score' => 'required',
    'course_details.2.d_Total_Score' => 'required'
]);

I have taken reference from here

But this doesn't seem to be working.

HTML CODE:

<input placeholder="SAT score " class="form-control form-control-sm valid" id="d_Score_Sub_Category_SAT" name="course_details[0][d_Total_Score]" value="" aria-invalid="false" type="text">

RESOLVED: As d3jn said, the validations should not override anywhere.

First of all, you can actually use wilcard syntax and let Laravel iterate through your corse_details with one rule: 'course_details.*.d_Total_Score' => 'required'. More about it here. Also provide code of where are you using this rules - in FormRequest class? Using Validator? Are there any exceptions? We need more info. — d3jn

Check dd($request->input('course_details')) when you send your requests. I assume "this doesn't seem to be working" means you are not getting any errors even when not specifying d_Total_Score. Or is it the opposite and you are always getting validation errors? — d3jn

I am getting array ( 'd_Total_Score' => NULL, ), for example. But it is required. And the form is getting submitted. But it should not. — Dushyant Joshi

Based on what dd($request->input('course_details')) showed there might be other input with the name="course_details[d_Total_Score]" somewhere after your original inputs and it's overriding the value that is sent with the request. — d3jn

You should be able to achieve what you are looking for like this:

course_details.*.d_Total_Score' => 'required'

I recently wrote something similar and I did it like this:

'contacts.*.name' => 'nullable|string|max:255',
'contacts.*.email' => 'nullable|email|max:255',
'contacts.*.phone' => 'nullable|phone:US|max:255',

My HTML looks like this:

<input class="form-control{{ $errors->has('contacts') ? ' is-invalid' : '' }}" id="contacts" name="contacts[0][name]" type="text" value="">
<input class="form-control{{ $errors->has('contacts') ? ' is-invalid' : '' }}" id="contacts" name="contacts[0][email]" type="text" value="">
<input class="form-control{{ $errors->has('contacts') ? ' is-invalid' : '' }}" id="contacts" name="contacts[0][phone]" type="text" value="">

<input class="form-control{{ $errors->has('contacts') ? ' is-invalid' : '' }}" id="contacts" name="contacts[1][name]" type="text" value="">
<input class="form-control{{ $errors->has('contacts') ? ' is-invalid' : '' }}" id="contacts" name="contacts[1][email]" type="text" value="">
<input class="form-control{{ $errors->has('contacts') ? ' is-invalid' : '' }}" id="contacts" name="contacts[2][name]" type="text" value="">

... so on

When you say it doesn't work, do you mean it's passing the validation or are you seeing errors? @DushyantJoshi

it is passing the validation. Means is is not being called.
