如果用户单击保存，我如何确保删除多个图像

问题描述

我相信这可以通过jquery完成。我有一个编辑预览，允许用户删除图像。每幅图像都有一个x按钮，如果单击该按钮会指向 destroyImg 功能。这里的问题是，删除操作甚至在用户单击保存按钮之前发生。目的是如果用户单击“保存”，则仅允许销毁打算删除的许多图像。 enter image description here

后控制器

public function destroyImg(images $images,$id)
{
    $try = images::find($id); 
    $try->delete();
   
    if (Auth::guard('web')->check()){
        $user = Auth::guard('web')->id() ;
        return redirect()->route('home',['user'=>$user]);
    }
    if (Auth::guard('SuperAdmin')->check()){
        $admin = Auth::guard('SuperAdmin')->id() ;
        return redirect()->route('admin.dashboard',['admin'=>$admin]);
    }
}

public function update(Post $post,Request $request)
{
    
    $data = request()->validate(['about' => 'required',]);
    $post->update( $data);
    if($request->hasFile('image')) {
        $files = $request->file('image');
        foreach($files as $file) {
             
            $name = time().'-'.$file->getClientOriginalName();
            $name = str_replace('','-',$name);
            echo $name;
                
            $file->move('images',$name);
                
            $post->images()->create(['image' => $name ]);
        }
    }

    if (Auth::guard('web')->check()) {
        $user = Auth::guard('web')->id() ;
        return redirect()->route('home',['user'=>$user]);
    }

    if (Auth::guard('SuperAdmin')->check()) {
        $admin = Auth::guard('SuperAdmin')->id() ;
        return redirect()->route('admin.dashboard',['admin'=>$admin]);
    }
}

路线

Route::delete('/trash/img-edit/{oneimage}','PostController@editDestroyImg')->name('edit.delete');
Route::patch('/p/update/{post}','PostController@update')->name('post.update');
