Laravel - 重定向到路由 POST

Question

如果验证器失败，我尝试重定向我的 POSTform，但它不起作用，因为它不是 GET 路由。我有一个用于选择产品的第一页，发布到第二页以向产品添加一个模型。如果验证器失败，我想重定向到第二页。

验证:

if ($validator->fails()) {
        return redirect('admin/modele/create')
             ->withErrors($validator)
             ->withInput();
}

路线:

Route::get('modele/select/product', 'ModeleController@selectProduct')->name('modele.selectProduct'); //get page for select product
Route::post('modele/selected/product', 'ModeleController@selectedProduct')->name('modele.selectedProduct');  //the product is selected, send it to form page
Route::post('modele/create/product/{produit}', 'ModeleController@storea')->name('modele.storea'); //is a store custom

Controller :

public function selectProduct() 
    {
        //
          $lesProduits = Produit::pluck('nom', 'id');
          return view('admin/modele/select', compact('lesProduits'));

    }

     public function selectedProduct(Request $request) 
    {
        //

            $unProduit = $request->get('produit');
            $id = ($request->get('produit'));

            $unProduit = Produit::where('id', $id)->pluck('nom', 'id');
            $uneCategorie = Produit::find($id)->categorie;
            $produit = Produit::find($id);
           //dd($uneCategorie)   ;
            //$categorie = $unProduit->categorie->id;

            return view('admin/modele/create', compact('unProduit', 'uneCategorie', 'produit'));

    }
public function storea(Request $request, $produit_id)
    {
        //
        $validator = Validator::make($request->all(), [
            'ref' => 'required|max:255',
            'prixHT' => 'required|max:9|numeric',
            'prixHTpromo' => 'max:9|numeric',
            'quantite' => 'required|numeric|max:255',
            't1' => 'max:255',
             't2' => 'max:255',
             't3' => 'max:255',
             't4' => 'max:255',
             't5' => 'max:255',
             't6' => 'max:255',
             't7' => 'max:255',
             't8' => 'max:255',
             't9' => 'max:255',
             't10' => 'max:255',
            'image' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048',

        ]);

        if ($validator->fails()) {
             return redirect('admin/modele/create')
                        ->withErrors($validator)
                        ->withInput();
        }
        else
        {        
            $unModele = New Modele();
            $unModele->produit_id = $produit_id;
            $unModele->ref = $request->get('ref');
            $unModele->prixHT = $request->get('prixHT');
            if ($request->get('prixHTpromo') != null)
            {
               $unModele->prixHPromoHT = $request->get('prixHTpromo');   
            }      
            $unModele->quantiteDebut = $request->get('quantite');
            for ($i = 1; $i < 11; $i++)
            {
                $name = 't'.$i;
                $nameDB = 'info'.$i;
                if ($request->get($name) != null)
                {
                    $unModele->$nameDB = $request->get($name);
                }
            }
            // photo 0,1             
            if($request->file('image') != null) // && $uneActualite->url != null)
            {
                //image code here
            }
            else
            {
                $unModele->image=null;
            }
          /////////////////////////
            $unModele->save();
            $request->session()->flash("success","Modèle ajouté.");
            return redirect(route('modele.index'));        
        }


    }

选择页面:

     {!! Form::open(array('route' => 'modele.selectedProduct')) !!}


                            <div class="form-group">
                 {!! Form::label('produit', 'Produit') !!}
                 {!! Form::select('produit',$lesProduits, null, array('class' => 'form-control')) !!}
                            </div>
                @if ($errors->has('produit'))
                            <div class="alert alert-danger" role="alert">
                                <ul>
                                    @foreach ($errors->get('produit') as $message) 
                                        <li>{{$message}}</li>
                                    @endforeach
                                </ul>
                            </div>
                            @endif




                            <button type="submit" class="btn btn-primary col-lg-12"><span class="glyphicon glyphicon-ok" aria-hidden="true"></span></button>
                            {!! Form::close() !!}

创建模型页面:

                    {!! Form::open(array('route' => ['modele.storea', $produit->id],'enctype' => 'multipart/form-data')) !!}


                    <div class="form-group">

我知道这已经很旧了，但我遇到了类似的问题，这是我的解决方案，重写以匹配主题所有者的帖子:

路线:

Route::match(['get','post'],'modele/selected/product', 'ModeleController@selectedProduct')->name('modele.selectedProduct');

Controller

$unProduit = $request->get('produit')??session('_old_input')['produit_id'];

创建模型页面

{{ Form::hidden('produit_id', $unProduit->id) }}

这至少适用于 Laravel 5.6 和 PHP 7+
