Insert array into database with Laravel

I have a form that returns an array with the values:

Número: {{Form::text('tel[]')}}
Proprietário: {{Form::select('proprietario[]',['Aluno'=>'Aluno','Pai'=>'Pai'])}}
Tipo: {{Form::select('tipo[]'['Pessoal'=>'Pessoal', 'Comercial'=>'Comercial'])}}

I’m trying to put it in the bank like this:

    $telefone=$_POST['tel'];    
    $proprietario=$_POST['proprietario'];
    $tipo=$_POST['tipo'];
    if(count($telefone)>0){
        for ($i = 0; $i < count($telefone); $i++) {
            $tel->numero=$telefone[$i];
            $tel->proprietario=$proprietario[$i];
            $tel->tipo=$tipo[$i];
        }
    }

The problem is that it is only inserting the last value of the array. What I am doing wrong?

See if in the generated html the name this one with clasps.

Yes. Displaying the page’s source code

you already did dd($telefone) to see what is stored?

Already, it is storing the data correctly in the variable. The impression I have, is that the for does not traverse the array, but I gave a echo in the $i and it’s okay.

What is the array of your entire collection, can make a echo '<pre>' . print_r($_POST); die(); ?

Yes, I can. The data is being captured by $_POST correctly.

It’s kind of weird! $_POST in Laravel?!?!? would not be Input::get?

$tel->tipo=$tipo[$i]; the equals signal for a normal variable within a loop, stores only one value, and they are being replaced until the last one arrives, so you only get the references of the last index of the traversed array.

Depends on your database.

Arrays represent more than one datum.

So I think the correct form would be, taking for example users and their various phones.

$dadosUsuario = Input::only('nome', 'email', 'idade');

$usuario = Usuario::create($dadosUsuario);

foreach((array) Input::get('telefones') as $telefone) 
{
      $dadosTelefone[] = [
            'usuario_id' => $usuario->id, 
            'telefone'   => $telefone

      ];
}

If you are "insert a array in the bank" will have to do gambiarras as json_encode:

 $dadosUsuario = Input::only('nome', 'email', 'idade', 'telefones');

 $dadosUsuario['telefones'] = json_encode($telefones);

 Usuario::create($dadosUsuario);

This last example is highly recommendable rsrsrs

In your case

I notice your coding pattern on Laravel is a little different than I’m used to seeing.

But I believe that this information is valid in all cases.

You are only entering the last value, because for you to enter in the bank, you have to call the method save at each iteration.

$telefone = $_POST['tel'];    

$proprietario = $_POST['proprietario'];

$tipo = $_POST['tipo'];

// Chamar o count a cada iteração é ruim

$count = count($telefone); 

if ($count > 0) {

    for ($i = 0; $i < $count; $i++) {
        $tel->numero = $telefone[$i];
        $tel->proprietario = $proprietario[$i];
        $tel->tipo = $tipo[$i];

        $tel->save(); // Salva o paranauê
    }
}
