Laravel foreach input all update fails because of form token - php

Question

I recently found my problem what is causing my form error.
I create a form post and loop throuh them
public function update()
{
$input = Input::all();
foreach ($input as $key => $value) {
$update = Setting::find($key);
$update->value = $value;
$update->save();
}
return Redirect::back();
}
The problem is i get the following error
Creating default object from empty value
Because the token is included in the form post what Laravel automaticly renders to a form
if i stop using Laravel form open and use the html form tag it all works fine.
Is there any way to bypass this with laravel form open or should i use the html form tag?

Answer 1

change
$input = Input::all();
to
$input = Input::except('_token');

Answer 2

Make sure your $update = Setting::find($key); returns a valid object, because, that error should be triggered when $update is NULL or not defined and you are trying to use this in your code
$update->value = $value;
This warning Creating default object from empty value occurs when E_STRICT is on in the system, but this is not the real problem, instead, you are not getting the desired result, most probably Setting::find($key) is not getting the thing you asked for and creating a new Setting object instead, check your model and make sure you are passing the right value in ::find($key), key should be primary key.
Update :
Also remember, when your using
$input = Input::all();
foreach ($input as $key => $value) { ... }
In this case, $key will be the name of your input/field used in the form and it may contain hidden _token field but _token is probably not available in the database as a field/column. So, you may try to get everything except _token
$input = Input::except('_token'); // get everything without _token
to get everything without _token field (but not sure if this solves the problem or not).
