new image in update form didn't change - php

Question

I made an update form wherein in i can edit and update current uploads in my renting shop project.
but i've been having this problem wherein the image isn't changing both in the page and database, but when i checked the storage/public/images it stores the same current image whenever i try to try again.
but the rest in my form is working fine and already changeable except the image.
Here is in my CarsController.php
public function update(Request $request, $id)
{
$car = Car::find($id);
$car->car_brand = $request->car_brand;
$car->car_name = $request->car_name;
$car->description = $request->description;
$car->car_type_id = $request->car_type_id;
if ($request->hasFile('image_location')) {
Storage::disk('public')->delete($car->image_location); // remove the old file.
$path = $request->image_location->store('images', 'public'); // save the new image.
$car->image_location = $path;
}
$car->save();
$request->session()->flash('message', 'The item has been updated.');
return redirect('/selections');
}
Here's the form
<div class="form-group">
<label>Image</label>
<input type="file" class="form-control" name="image_location" required>
</div>
i don't know what could possibly wrong. anyone please enlighten me. Thanks in advance. Anyway the migrated column name is image_location
also here's in my store()
public function store(Request $request)
{
$car = new car;
$car->car_brand = $request->car_brand;
$car->car_name = $request->car_name;
$car->description = $request->description;
$car->car_type_id = $request->car_type_id;
$path = $request->image_location->store('images', 'public');
$car->image_location = $path;
$car->availability = $request->availability;
$car->save();
$request->session()->flash('message', 'The item has been added.');
return redirect('/selections');
}

I'm afraid your code works perfectly for me.
You could try adding some log lines and see where the problem lies:
use Illuminate\Support\Facades\Log;
if ($request->hasFile('image_location')) {
Log::debug('File has been found in request.');
// Check if the old car image exists.
Log::debug($car->image_location . (Storage::disk('public')
->exists($car->image_location)? ' exists': ' does not exist'));
Storage::disk('public')->delete($car->image_location); // Remove the old file.
// Check if the old car image (if it existed) has been deleted.
Log::debug($car->image_location . (Storage::disk('public')
->exists($car->image_location)? ' exists': 'does not exist'));
$path = $request->image_location->store('images', 'public'); // save the new image.
// Check if the new file has been saved correctly.
Log::debug($path . (Storage::disk('public')
->exists($path)? ' exists': 'does not exist'));
$car->image_location = $path;
}
After uploading a new image, my storage/logs/laravel.log shows:
[2019-12-28 10:18:03] local.DEBUG: File has been found in request.
[2019-12-28 10:18:03] local.DEBUG: images/WPMkdG56f4YXsd3IUJ3Ar1DbXF0QmtDz9bs0lKoI.gif exists
