if the second email input is filled in the second row then there is also one checkbox should be checked and so on.
#for ($i = 0; $i < 4; $i++)
<input type="email" id="email" name="email[]">
<input type="checkbox" name="task[{{ $i }}][]" value="sign">
<input type="checkbox" name="task[{{ $i }}][]" value="initial">

this is the code in my controller its not catch the task field if it's null.
$validatedData = $request->validate([
'email.0' => 'required_without_all:email.*|email',
'email.1' => 'nullable|email',
'email.2' => 'nullable|email',
'email.3' => 'nullable|email',
'task.*' => 'required_if:email.*,filled',
]);

Answer 1

I have searched a lot everywhere but the following code worked for me:
$request->validate([
'email.*' => 'nullable|email',
'email.0' => 'required|email',
'task.0' => 'required_with:email.0',
'task.1' => 'required_with:email.1',
'task.2' => 'required_with:email.2',
'task.3' => 'required_with:email.3',
]);

You can try this
First, change the field name like below
Here I used data as an array index in order to map the email, sign, date, and initial fields under the same index
#for ($i = 1; $i <= 4; $i++)
<input type="email" id="email" name="data[{{ $i }}][email]">
<input type="checkbox" name="data[{{ $i }}][sign]" value="sign">
<input type="checkbox" name="data[{{ $i }}][initial]" value="initial">
<input type="checkbox" name="data[{{ $i }}][date]" value="date">
<input type="checkbox" name="data[{{ $i }}][cc]" value="cc"
#endfor
Once you pass email in the first box and select the initial option and keep the rest unchanged and add dd($request->all()) in the controller you will output as given below.
array:2 [▼
"data" => array:4 [▼
1 => array:2 [▼
"email" => "someemail#gmail.com"
"initial" => "initial"
]
2 => array:1 [▼
"email" => null
]
3 => array:1 [▼
"email" => null
]
4 => array:1 [▼
"email" => null
]
]
]
Now add Laravel validation with the given below
$request->validate([
'data' => 'required|array',
'data.*.sign' => 'sometimes|required_with:data.*.email',
'data.*.date' => 'sometimes|required_with:data.*.email',
'data.*.cc' => 'sometimes|required_with:data.*.email',
'data.*.initial' => 'required_with:data.*.email',
'data.*.email' => 'required_with:data.*.sign|required_with:data.*.cc|required_with:data.*.date|required_with:data.*.initial',
]);
This will validate the form data both ways around.
NOTE: You must add some custom validation to check if non of the values are selected.
I hope you find this helpful.

<?php
class CourseLevelsRequest
{
private array $rules = [
'course_levels' => 'required|array',
];
public function __construct()
{
$this->makeValidationRules();
request()->validate($this->rules);
// your custom logic
}
private function makeValidationRules(): void
{
collect(request('course_levels'))->each(function ($courseLevelRequest, $index) {
$this->rules['course_levels.'.$index.'.course_id'] = 'required';
$this->rules['course_levels.'.$index.'.level'] = 'required|string|max:255';
$this->rules['course_levels.'.$index.'.programmatic_course_level_name']
= 'required|string|max:255|unique:course_levels,programmatic_course_level_name,'.$courseLevelRequest['id'];
$this->rules['course_levels.'.$index.'.fee'] = 'required|numeric';
});
}
}
Here, I have full control of validation rules
