Laravel 模型事件：delete() 不会从存储中删除文件

发布于01月04日

我正在使用FilePond进行图像上传.它为上传的图像生成随机字符串，并以数组的形式保存在数据库中.

我try 执行以下操作，它会删除记录，但不会删除与其关联的文件.

Since it's an array, I tried this:个

foreach($this->attachments as $attachment) {
            if(File::exists(storage_path($attachment))) {
                Storage::delete($attachment);
            }
        }

我还try 了这个:

if(Storage::exists($this->attachments))
{
  Storage::delete($this->attachments);
}

注: 我使用Filament作为管理仪表板.

这些文件将在storage/app/public/vehicle-images保存

我做了php artisan storage:link次，所以公共文件夹显示``Public/store/Vehicle-Images```

推荐答案

在本例中，文件位于:Laravel/storage/app/public/vehicle-images

$filename = 'test.txt';

if(\File::exists(storage_path('app/public/vehicle-images/'.$filename))){
   \File::delete(storage_path('app/public/vehicle-images/'.$filename));
}

为了更好地了解文件的位置，在此之后，您只需执行循环判断/删除即可.

你可以在这里阅读更多:https://laravel.com/docs/9.x/filesystem#the-public-disk

您还可以在以后为该文件夹指定一个磁盘，以使其更易于访问.

Finally:个

foreach($this->attachments as $attachment) {

    //Option #1: if $attachment == file.txt
    //use this code:
    if(\File::exists(storage_path('app/public/vehicle-images/'.$attachment))){
       \File::delete(storage_path('app/public/vehicle-images/'.$attachment));
    }
    
    //Option #2: if $attachment == vehicle-images/file.txt
    //use this code:
    if(\File::exists(storage_path('app/public/'.$attachment))){
       \File::delete(storage_path('app/public/'.$attachment));
    }

}
