Question

这是我为所有控制器使用的一般功能所做的HelperController

namespace App\Http\Controllers;

use Session;
use Redirect;
use App\Http\Requests;
use Illuminate\Http\Request;

class HelperController extends Controller
{

public function UploadImage($UploadImage,$folder)
{
    if($UploadImage->isValid() && $UploadImage->getMaxFilesize()>=$UploadImage->getSize())
    {
        if($UploadImage->guessExtension()=='jpeg' || $UploadImage->guessExtension()=='jpg' || $UploadImage->guessExtension()=='gif' || $UploadImage->guessExtension()=='png')
        {
            $destinationPath = public_path().'/assets/images/'.$folder.'/';
            $uploadedFilename = time().'_'.$UploadImage->getClientOriginalName();
            $UploadImage->move($destinationPath,$uploadedFilename);

            return $uploadedFilename;
        } else {
            return Redirect::to('/profile')->with('errorMessage','Extension Issue');
            // or
            // return back()->with('errorMessage','Extension Issue');
            // or
            // return "extension";
        }
    } else {
        return Redirect::to('/profile')->with('errorMessage','Size Issue');
        // or
        // return back()->with('errorMessage','Size Issue');
        // or
        // return "size";
    }
}

public function beautifyRole($role)
{
    return ucwords(str_replace('_',' ',$role));
}

}

这是Profile Controller我使用HelperController的UploadImage函数上传图片

namespace App\Http\Controllers;

use Auth;
use App\User;
use App\Http\Requests;
use Illuminate\Http\Request;

class ProfileController extends Controller
{

public function UpdateProfile(Request $request)
{

    $User = User::where('id',Auth::User()->id)->first();

    $User->name = $request->Input('name');
    $User->email = $request->Input('email');
    $User->password = bcrypt($request->Input('password'));

    // Check if New Avatar if Uploaded
    if($request->avatar!=null){
        $HelpUpload = new HelperController;
        $avatar = $HelpUpload->UploadImage($request->avatar,'users');

        /*
        if($avatar=='size'){
            return back()->with('errorMessage','File Size Issue');
        } elseif($avatar=='extension'){
            return back()->with('errorMessage','File Extension Issue');
        } else {
            $User->avatar = $avatar;
        }
        */
    }

    $User->save();

    return Redirect('/profile')->with('successMessage','Profile Updated Successfully');

}

}

但是如果不满足尺寸或扩展条件则存在问题，我希望页面重定向到上一页或直接重定向到配置文件页面。相反，它会返回到UploadProfile函数并始终显示＆＃34; Profile已成功更新＆＃34;即使发生任何错误也要留言。

我想删除UpdateProfile函数上的控件结构。它在我返回错误消息然后在更新配置文件功能上检查它时有效。

我们可以直接从HelperController中的UploadImage函数重定向到配置文件页面，而无需返回到正常的函数。

如果您的图片上传功能不像

那样，您可以使用redirect()->back()方法和错误消息

return redirect()->back()->withErrors("Your error message");

Laravel：直接重定向到页面而不返回到以前的功能
