Question

我有两个名为＆＃39; posts＆＃39;和照片＆＃39;照片＆＃39;表存储＆＃39; post＆＃39;的图像。一篇文章可以有很多照片，所以关系是一对多的。我已经设法创建了商店方法，我已经创建了一个视图来显示包含照片的帖子。以下是功能：

public function show($titleslug) {
        $post = Post::where('titleslug', '=', $titleslug)->first();
        $images = $post->photos;
        return view('dashboard/posts/show', compact('post','images', $post, $images));
}

节目视图：

<div class="contentpanel">
    <div class="row blog-content">
        <div class="col-sm-12">
            <div class="panel panel-default panel-blog">
                <div class="panel-body">
                    <div class="panel-body">

                        <ul class="blog-meta">

我希望能够从节目视图中删除图像，该怎么做？我需要为它创建一个函数吗？如果是这样，那么该功能将如何？这就是全部，谢谢，对不起要求太多了

Answer 1

首先，通过添加以下内容编辑视图中的delete form：

...
<input type="hidden" name="image_id" value="{{ $images->id }}" /> // Assuming that photo id is in your $images object
...

然后，您可以从POST创建与image/delete功能相关联的delete路由controller，以删除预期的图片：

public function delete() {
    $image_id = $request->only('image_id');

    $image = Photo::where('id', '=', $image_id)->delete(); // Assuming that you have a Photo model

    return view('dashboard/posts/show');
}

删除属于帖子的文件？
