Cart update in laravel - laravel

Question

have a form like this. This is an update form, i just need to update qty foreach product in cart.
But i have tried to explode each results and not work... it return object2array conversion error... its the first time that i get this error How i can save this in DB?
<form action="update">
#foreach($products as $product)
<input type="text" name="products[]">
<input type="text" name="qty[]">
#endforeach
<input type="submit" calss="btn btn-primary">
This is my controller:
Route::post('aggiorna', function() {
$quantita = Input::all();
$carrelli = \App\Models\Carrello::where('entry_by', \Session::get('uid'))->get();
$quantita = explode(',', $quantita);
$i = 0;
foreach($carrelli as $carrello) {
$carrello->quantita = $quantita[$i];
$i = $i++;
}
return Redirect::to('carrello');
});
Thanks in advance.

Answer 1

you do the iteration for each $carreli that exist on your database, however you never save the value.
Route::post('aggiorna', function() {
$quantita = Input::all();
$carrelli = \App\Models\Carrello::where('entry_by', \Session::get('uid'))->get();
$quantita = explode(',', $quantita);
$i = 0;
foreach($carrelli as $carrello) {
$carrello->quantita = $quantita[$i];
$i = $i++;
$carrelo->save();
}
return Redirect::to('carrello');
});
add the $carrelo->save(); after you update the value in order to save it on db.
Also careful when you use Input::all();. That means that your data array contains both products and quantities. I would suggest using the following code:
Route::post('aggiorna', function() {
$quantita = Input::get('qty');
$products = Input::get('products');
$carrelli = \App\Models\Carrello::where('entry_by', \Session::get('uid'))->get();
$quantita = explode(',', $quantita);
$products = explode(',', $products);
$i = 0;
foreach($carrelli as $carrello) {
$carrello->quantita = $quantita[$i];
$carrello->products = $products[$i];
$i = $i++;
$carrelo->save();
}
return Redirect::to('carrello');
});
However since i do not know what you are trying to achieve, I posted both solutions here.
