使用 foreach 循环删除 laravel 中的多条记录

Question

我正在尝试使用 product_id 删除多张图片，我可以一次删除一张图片，但我正在弄清楚如何将 $i=0 之类的变量插入到循环中，但它在 laravel 中不起作用。到目前为止这是我的代码

   public function ImageDelete($slider_id)
{
    //int $i=0; Had introduced this but doesn't work
    $slider = Products::findOrFail($slider_id);
       foreach($slider as $product){
          $product_images=$slider->images()->get();
           $image_path = public_path().'\images2\'.$product_images[0]->filename;
           File::delete($image_path);
         //$i++;
    }
    $slider->delete();

    return response()->json(['success'=>'Pics deleted successfully!']);
}

Answer 1

findOrFail方法return只有一项。所以你不能迭代它。

您可以使用 each method

$product = Products::findOrFail($id);
$images = $product->images()->get();

$images->each(function ($file, $key) {
  $filePath = public_path("images2/") . $file->filename;
  File::delete($filePath);
});

// Delete the product
$product->delete();

Answer 2

试试这个：

   public function ImageDelete($slider_id)
{
    $product = Products::find($slider_id);

    $product_images=$product->images()->get();

       foreach($product_images as $product_image){
           $image_path = public_path().'\images2\'.$product_image->filename;
           File::delete($image_path);
        }
    $product->delete();

    return response()->json(['success'=>'Pics deleted successfully!']);
}
