Updating multiple records using Laravel 5.3 model binding - php

Question

I am pulling multiple records from MySQL and looping through model binding and filling all the input fields with some data.
Now, I may change 2 or 10 or all 26 fields and hit update button. I want to update all the records. Now, I don't know how $id works here? usually I update single record and I have $id which I can find and update only that field.
But that's not the case here. I am pulling 13 records(or 26 fields). 13 field_1 and 13 field_2. How to update all?
mycode
Database
Table
-id
-name
-field1 (updating this one)
-field2 (updating this one)
Routes
Route::get('/cat' , 'AdminController#cat');
Route::patch('/cat/{$id}/update','AdminController#cat_update');
Controller
public function cat(){
$cattfs = Catf::all();
return view('/cat',compact('cattfs'));
}
public function cat_update(Request $request, $id) // id = 1
{
$rules = array(
'field1' => 'required',
'field2' => 'required'
);
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails()) {
return Redirect()->back()->withErrors($validator);
} else {
$cat = Cattf::find($id); //This wont work :/
$cat ->field1 = Input::get('field1');
$cat ->field2 = Input::get('field2');
$cat ->save();
return redirect('/cat');
}
}

I don't think you can do this with Model binding (correct me if I'm wrong someone).
What you can instead do is generate an array of data to post to your controller.
For example:
{!! Form::open(['route' => 'catupdate']) !!}
#foreach ($cattos as $catto)
<tr>
<td>{{$catto->name}}</td>
<td>{!! Form::text('categories['.$catto->id.'][field1]', null, ['class'=>'form-control']) !!}</td>
<td>{!! Form::text('categories['.$catto->id.'][field2]', null, ['class'=>'form-control']) !!}</td>
</tr>
#endforeach
{!! Form::close() !!}
You should then receive an array in your controller, which you can loop around and update each record.
public function catupdate()
{
$categories = request()->input('categories');
foreach($categories as $id => $values) {
$cat = Cattf::find($id);
$cat->field1 = $values['field1'];
$cat->field2 = $values['field2'];
$cat->save();
}
}
You can then also validate the array by doing the following in your Request file
public function rules()
{
return [
'categories.*.field1' => 'required',
'categories.*.field2' => 'required'
];
}
this is untested and is an example demonstrating the concept
