Laravel 8 - Image not deleted from storage + not updating when "Edit" - php

Question

possible "duplicate": Laravel - Delete images from storage / update post
I want laravel to delete the old image and replace it with new uploaded image in the edit form. I tried doing this:
if( $request->hasfile('violationStatement') ) {
$destination = 'violations/' . $violation->violationStatement;
// Deletes the file if it exists
if( File::exists($destination) ) {
File::delete($destination);
}
$file = $request->file('violationStatement');
$extension = $file->getClientOriginalExtension();
$filename = time() . '.' . $extension;
$file->move('violations/', $filename);
$violation->violationStatement = $filename;
}
$violation->update();
But the image is not deleted nor updating. In addition, I want to have a condition when I just want to edit data without uploading new image...
Here is the routing:
// Traffic Violations
Route::controller(TrafficViolationController::class)->group(function () {
Route::get('violations', 'index')->name('violations.index'); // Index page (DataTable)
Route::get('violations/create', 'create')->name('violations.create'); // The form for adding new records
Route::post('violations/create', 'store')->name('violations.store'); // Add new to DB
Route::get('violations/edit/{violation}', 'edit')->name('violations.edit'); // The form for editing records
Route::put('violations/edit/{violation}', 'update')->name('violations.update'); // Update record to DB
Route::get('violations/{violation}', 'destroy')->name('violations.destroy'); // Delete from DB
});

Answer 1

First make sure of namespace
use Illuminate\Support\Facades\File;
Then edit $violation->update() to $violation->save();
And if the path in public folder use this method public_path() as this
$destination = public_path('violations/' . $violation->violationStatement);
But if the path in storage folder use this method storage_path() as this
$destination = storage_path('violations/' . $violation->violationStatement);

Answer 2

I use Intervention\Image\Facades\Image for uploading image And Illuminate\Support\Facades\File For Manage Directories. below Code replace Pic If Exist. think now you have 123.jpg and you want replace it. it replace old pic with new one. if your image name is difference you can delete old one.
use Illuminate\Support\Facades\File;
use Intervention\Image\Facades\Image;
//Get Data Of uploaded pic
$file = $request->file('violationStatement');
$srcPath = $file->getRealPath();
$size = $file->getSize(); // if You Need Pic Size
$extension = $file->getClientOriginalExtension();
//Start Uploading
$Image = Image::make($srcPath);
$destPath = public_path("violations");
File::ensureDirectoryExists($destPath); // Check Directory Exist Or Make
$filename = time() . '.' . $extension;
$Image->save($destPath.'/'.$filename);
at last I suggest add some unique thing to Your Image Name because it may two user upload picture at Same Time!!! and One Picture replaced.
