Question

我在laravel的用户表中有多个字段，但是我只想从用户表中删除图像，请让我知道该过程。这是我的usercontroller.php文件。

public function userprofile(Request $request)
{

    $user = DB::table('users')->where('id',Auth::user()->id)->get();
    //dd($user);
    $userWish = DB::table('package_wishlist')->where('user_id',Auth::user()->id)->where('is_active',1)->count();

    $userComp = DB::table('package_comparison')->where('user_id',Auth::user()->id)->where('is_active',1)->count();

    $bookings = DB::table('agent_bookings')
                ->where('cust_email',Auth::user()->email)->get();
     return view('user/profile',['bookings'=>$bookings,'user'=>$user[0],'userWish'=>$userWish,'userComp'=>$userComp]);

}

public function imagedestroy($id)
{
    $image = DB::table('users')->where('id', $id)->get();
    $file= $image->user_image;
    $filename = public_path().'/uploads/user_uploads/'.$image;
    File::delete($filename);
}

这是我的profile.blade.php文件。

@foreach($user as $delimage)
 <a onclick="event.preventDefault();
  document.getElementById('delete-image-form').submit();" 
 class="btn btn-default btn-sm btn-block">Delete</a>
 <form id="delete-image-form" method="POST" action="{{ 
 route('delimage.imagedestroy', $delimage->id) }}"  
 style="display: none;">
  @method('DELETE')
  @csrf
</form>
@endforeach

我的web.php文件是这个...

Route::get('/userprofile', 'CustomHomeController@userprofile')->name('userprofile');
Route::get('/userprofile/{id}', 'CustomHomeController@imagedestroy')->name('imagedestroy');

使用first（）代替get（）。 get（）为您提供一个集合，您需要对其进行迭代以获取属性。这样就无法获得

这样的用户的图片

$image = DB::table('users')->where('id', $id)->get();
$file= $image->user_image; //this won't work.

尝试

public function imagedestroy($id)
{
    $image = DB::table('users')->where('id', $id)->first();
    $file= $image->user_image;
    $filename = public_path().'/uploads/user_uploads/'.$image;
    File::delete($filename);
}

您的userprofile方法应该像

public function userprofile(Request $request)
{

    $user = DB::table('users')->where('id',Auth::user()->id)->first();
    //dd($user);
    $userWish = DB::table('package_wishlist')->where('user_id',Auth::user()->id)->where('is_active',1)->count();

    $userComp = DB::table('package_comparison')->where('user_id',Auth::user()->id)->where('is_active',1)->count();

    $bookings = DB::table('agent_bookings')
                ->where('cust_email',Auth::user()->email)->get();
     return view('user/profile',['bookings'=>$bookings,'user'=>$user,'userWish'=>$userWish,'userComp'=>$userComp]);

}

因此，您无需在视图中进行迭代。只需使用

<a onclick="event.preventDefault();
  document.getElementById('delete-image-form').submit();" 
 class="btn btn-default btn-sm btn-block">Delete</a>
<form id="delete-image-form" method="POST" action="{{ 
 route('imagedestroy', $user->id) }}"  
 style="display: none;">
  @method('DELETE')
  @csrf
</form>
