如何以Laravel中的单一形式上传来自两个不同文件上传字段的多个图像

Question

如何从我的表单中的两个单独的文件上传选项中传递多个图像文件，然后存储到数据库中？这是我的模式和控制器代码。

Schema::create('images', function (Blueprint $table) {
        $table->increments('image_id');
        $table->increments('book_id')->unsigned();
        $table->string('coverPageImage');
        $table->string('previewPageImage');
        $table->timestamps();
  });

表单字段：BookId，文件上传以进行coverPageImage，文件上传的文件上传PreviewPageImage。coverPageImage和PreviewPageImage都通过了多个图像。

我能够将图像上传到文件夹中并保存到数据库中以进行单个文件上传。

$product_images = $request->file('coverPageImage');
foreach($product_images as $product_image){
   $coverImage_name = $product_image->getClientOriginalName();
   $upload = $product_image->move('images', $coverImage_name); 
   Image::create([
     'book_id' => $book_id,
     'cover_images' => $coverImage_name
      ]);
}
$preview_pages = $request->file('previewPageImage')
foreach($preview_pages as $preview_image){
   $previewImage_name = $preview_image->getClientOriginalName();
   $upload = $preview_image->move('images', $previewImage_name); 
      Image::create([
        'book_id' => $book_id,
        'preview_images' => $previewImage_name
      ]);
    }

我想使用以下方式：

 Image::create([
    'book_id' => $book_id,
    'cover_images' => $coverImage_name,
    'preview_images' => $previewImage_name
 ]);

，但是我在使用两个不同的文件图上使用foreach循环时被卡住了。任何建议或提示。

如果您确定$coverImage_name和$previewImage_name之间总是有1：1的关系，那么您可以将它们推入数组，循环循环数组，然后从内。

$images = [];
$product_images = $request->file('coverPageImage');
foreach ($product_images as $idx => $product_image){
    $coverImage_name = $product_image->getClientOriginalName();
    $upload = $product_image->move('images', $coverImage_name);
    $images[$idx]['cover_image'] = $coverImage_name;  
} 
$preview_pages = $request->file('previewPageImage')
foreach($preview_pages as $idx => $preview_image){
    $previewImage_name = $preview_image->getClientOriginalName();
    $upload = $preview_image->move('images', $previewImage_name); 
    $images[$idx]['preview_image'] = $previewImage_name;
}
foreach($images as $idx => $arr) {
    Image::create([
        'book_id' => $book_id,
        'cover_images' => isset($arr['cover_image']) ? $arr['cover_image'] : null,
        'preview_image' => isset($arr['preview_image']) ? $arr['preview_image'] : null
    ]);
}
