Model event for deleting files

[DevMushref]

I've found few discussions here requesting/asking how to delete files from storage. So here is how I did it.

In your model file

Create a public function called delete().

Within it you have few options to make

1- If the file is single and NOT required:

if (!is_null($this->attachment) && File::exists('storage/' . $this->attachment)) {
   File::delete('storage/' . $this->statement);
}

2 - If the file is single and IS required:

if (File::exists('storage/' . $this->attachment)) {
   File::delete('storage/' . $this->statement);
}

3- If the files are multiple and are NOT required:

foreach ($this->images as $image) {
     if (!is_null($this->images) && File::exists('storage/' . $image)) {
         File::delete('storage/' . $image);
    }
}

4- If the files are multiple and ARE required:

foreach ($this->images as $image) {
     if ((File::exists('storage/' . $image)) {
         File::delete('storage/' . $image);
    }
}

Why is_null()?

When I tried to delete a record that doesn't have multiple images uploaded, I get an error saying that the image directory is NULL.
So what I basically did is tell the software that if the array is NOT null aka !is_null() and the files DO exist, then delete them.

Don't forget to add parent::delete(); at the end of your delete() method to delete the records too.

How does the code read the directory URL?

It always saves in the storage/ folder. In your Filament resource, if you set the directory then it will be part of the $record saved in database.

For example:

I have a FileUpload filed that saves files in a folder called reports:

Forms\Components\FileUpload::make('attachment')
     ->image()
     ->directory('reports')

If you want to call the image in a custom blade then you should call it like so:

<img src="storage/ {{ $record->attachment }}" />

The URL will be storage/ + reports/image.png. If no directory was set: storage/ + image.png.

So always keep in mind that Filament saves the directory name (if available) as well as the image name.

Hope it helped in your case!
