Laravel - Upload to Existing Model Record - laravel

Question

Maybe it's because I'm tired, but I can't seem to get a simple upload working for one of my models.
On the show details page of my customers (who are NOT users) model, I have a simple form where a user can upload the logo of the customer.
The form:
<form enctype="multipart/form-data" action="/customers/i/{{$customer->url_string}}" method="POST">
<input type="file" name="logoUpload">
<input type="hidden" name="_token" value="{{csrf_token()}}">
<input type="submit" class="pull-right btn btn-sm btn-primary" value="Upload">
</form>
The Controller:
public function logoUpload(Request $request){
if($request->hasFile('logoUpload')){
$path = Storage::putFile('public/customer/uploads', new File(request('logoUpload')));
$customer->car_logo = $path;
$customer->save();
return back();
}
}
I know the issue is that I haven't defined $customer in the controller since the file does actually store itself in the correct folder after I click submit, but it does not hit the database at all.
Update
The current customer details url:
http://localhost:8000/customers/i/dsdado9a98w78721
The web definition for the post route:
Route::post('/customers/i/{customer}', 'CustomerController#logoUpload');

Answer 1

You have to create a hidden field in your form that contains the customer id and then use it in your controller to update it with the new file path, here is an example:
View
<form enctype="multipart/form-data" action="/customers/i/{{$customer->url_string}}" method="POST">
<input type="file" name="logoUpload">
<input type="hidden" name="_token" value="{{csrf_token()}}">
<!-- customer_id field -->
<input type="hidden" name="customer_id" value="{{$customer->id}}">
<input type="submit" class="pull-right btn btn-sm btn-primary" value="Upload">
</form>
Controller
public function logoUpload(Request $request){
if($request->hasFile('logoUpload')){
$path = Storage::putFile('public/customer/uploads', new File(request('logoUpload')));
// get customer
$customer = Customer::find($request->customer_id);
$customer->car_logo = $path;
$customer->save();
return back();
}
}

You have some options, here is a simple one, with only adjusting that controller method:
public function logoUpload(Request $request, $customer)
{
$customer = Customer::where('url_string', $customer)->firstOrFail();
if($request->hasFile('logoUpload')){
$path = Storage::putFile('public/customer/uploads', new File(request('logoUpload')));
$customer->car_logo = $path;
$customer->save();
return back();
}
...
}
We have added a parameter to the method signature to accept the route parameter. We then find the model via url_string matching that parameter.
You also could setup route model binding as well to do the resolving of that model based on the route parameter for you.
