拉维尔的表格更新结果是302

我面临一个302重定向问题,同时发布数据,以更新所有已成功更新的内容,但我得到302和我的页面重定向的图像除外。

这是我的表格代码:

{!! Form::model($post, ['method' => 'PATCH','route' => ['posts.update', $post->id],'data-parsley-validate' => '','class' => 'form-horizontal','files'=>true,'name'=>'updateabout']) !!}

    <br>

{!! Form::close() !!} 

还有我的控制器:

public function update(Request $request, $id)
{
    // Validate the data
    $postdata = Post::find($id);

    //print_r($post);

    if ($request->input('slug') == $postdata->slug) {
        //echo 'slug match';
        //exit();
        $this->validate($request, [
            'title'            => 'required|max:255',
            'category_id'      => 'required|integer',
            'long_description' => 'required',
        ]);
    } else {
        //echo 'new slug matching';
        //exit();
        $this->validate($request, [
            'title'            => 'required|max:255',
            'slug'             => 'required|alpha_dash|min:5|max:255|unique:posts,slug',
            'category_id'      => 'required|integer',
            'long_description' => 'required',
        ]);
    }

    if ($request->hasFile('imagemain')) {

        //echo 'request has old file to unlink ';
        // exit();
        //unlink($request->get('image'));
        // Get filename with the extension
        $filenameWithExt = $request->file('imagemain')->getClientOriginalName();
        // Get just filename
        $filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
        // Get just ext
        $extension = $request->file('imagemain')->getClientOriginalExtension();
        $fileNameToStore = $filename . '_' . time() . '.' . $extension;
        // Upload Image
        $path = $request->file('imagemain')->move('public/blogsimages', $fileNameToStore);
        // Filename to store
        echo $fileNameToStore = $path;
    } else {
        $fileNameToStore = $request->input('imageold');
        // exit();
    }

    // Save the data to the database
    $post = Post::find($id);

    $post->title = $request->input('title');
    $post->slug = $request->input('slug');
    $post->category_id = $request->input('category_id');
    $post->description = $request->input('description');
    $post->short_description = $request->input('short_description');
    $post->date = $request->input('date');
    $post->image = $fileNameToStore;
    $post->meta_title = $request->input('meta_title');
    $post->meta_keywords = $request->input('meta_keywords');
    $post->authorname = $request->input('authorname');

    $post->save();

    if (isset($request->tags)) {
        $post->tags()->sync($request->tags);
    } else {
        $post->tags()->sync([]);
    }

    // set flash data with success message
    Session::flash('success', 'This post was successfully saved.');

    // redirect with flash data to posts.show
    return redirect()->route('posts.show', $post->id);
}

当我发布数据时,除显示302的图像和表格外,所有内容都按照要求更新,以下是屏幕截图: 我的路线是: Route::resource('posts', 'PostController');
