Laravel : store array of input

@Nicho

@php $email = count($numbers); @endphp

where $numbers come from? You need to use wire:model or something else to update variable dynamically. Otherwise send the form first with number input only and display second form with email input based on user entered number.

@AungHtetPaing__ The $numbers actually a collumn in the table, because in the controller there's $email->numbers, so i think by doing the $numbers i think it should work, this is my first time of using array method in laravel

@Nicho

count(): Argument #1 ($value) must be of type Countable|array, null given

You are getting that error because $numbers is null. You didn't send $numbers from controller. Am I right? And you should make email input array. No need to save numbers to table if you loop and save email one by one(5 rows for 5 emails).

<tr>
            <td>
                <label>Email.{{$i}}</label>
                <input type="text" required class="form-control @error ('email') is-invalid @enderror" 
                id="email" name="email[]" autocomplete="off">
            </td>
        </tr>

public function store(Request $request){
        $numbers= $request->numbers;
        $emails = $request->email;
		
        for($count = 0; $count < count($numbers); $count++){
            emails::create([
				'email' => $emails[$count]
			]);
        }
        return redirect ('/home/');
    }

@AungHtetPaing__ Yess i didn't put the $numbers in the controller, in the controller i put $email->numbers = $request->numbers because i want it to get the number value first, then it show how many email input it need like in this case

Input case :

How many book : 5

Email number 1 : [email protected]
Email number 2 : [email protected]
Email number 3: [email protected]
Email number 4: [email protected]

@AungHtetPaing__ Ok my bad, i should made the email input array. Thank you for the correction

@Nicho

Yess i didn't put the $numbers in the controller, in the controller i put $email->numbers = $request->numbers

You still don't get what I am talking. If you use variable in blade, you need to sent data from controller. So in your case

public function create() {
	$numbers = 5;
	return view('blade', compact('numbers'));
}

// in blade
count($numbers);

do you get my point now?

Ok my bad, i should made the email input array. Thank you for the correction

So count(): Argument #1 ($value) must be of type Countable|array, null given solved?

@AungHtetPaing__ I tried to follow it like this

The controller :

public function store(Request $request){
        $numbers = $request->numbers;
        $emails = $request->email;
        for($count = 0; $count < count($numbers); $count++){
            emails::create([
                'email'=>$emails[$count]
            ]);
        }
        return redirect ('/home/');
    }

The blade :

<form action="{{route('EmailStore')}}" method="post">
    @csrf
    <div class="form-group">
        <label>How many people</label>
        <input type="text" required class="form-control @error ('numbers') is-invalid @enderror" 
        id="numbers" name="numbers" autocomplete="off">
    </div>
    @php
        $emails = count($numbers);
    @endphp
    @for ($i = 0; $i < $emails; $i++)
        <tr>
            <td>
                <label>Email.{{$i}}</label>
                <input type="text" required class="form-control @error ('email') is-invalid @enderror" 
                id="email" name="email[]" autocomplete="off">
            </td>
        </tr>
    @endfor
    <button type="submit" class="btn btn-info" id="btn_submit" 
        style="background-color: #eefa69; border:none; color:black">Submit</button>
</form>

And still got the error count(): Argument #1 ($value) must be of type Countable|array, null given

@Nicho I can't explain anymore. The error is simple your $numbers is null. So make sure it is not null. I already explained in previous replies.
