Object of class Illuminate\Validation\Validator could not be converted to string

问题

I'm yet to understand what needed to be fixed in the code making it to generate the error. What is to be put right?

This is the code:

public function store(Request $request){

        $validator = Validator::make($request->all(), [
                'user_id'                       => 'required|numeric',
                'company_id'                    => 'required|numeric',
                'product_id'                    => 'required|numeric',

                'tankerTotankerDesc'            => 'alpha_num|min:5',
                'tankerTakeOverDesc'            => 'alpha_num|min:5',
                'costFreightInsuranceDesc'      => 'alpha_num|min:5',
                'freightOnBoardDesc'            => 'alpha_num|min:5',

                'tankerTotankerPrice'           => 'numeric|required_with:tankerTotankerDesc',
                'tankerTakeOverPrice'           => 'numeric|required_with:tankerTakeOverDesc',
                'costFreightInsurancePrice'     => 'numeric|required_with:costFreightInsuranceDesc',
                'freightOnBoardPrice'           => 'numeric|required_with:freightOnBoardDesc',

                'optional_procedure'            => 'alpha_num|min:5',
                'optional_procedure_price'      => 'numeric|required_with:optional_procedure',
                'business_type'                 => 'required'
        ]);

        if ($validator->fails()) {
            redirect()->route('productUniqueCreate', $validator)->with('message', 'Record successfully created');
        }else{
           $product_id = $request->product_id;       
           $procurementUnique = ProcurementUnique::firstOrNew(array('product_id'=>$product_id));
           $procurementUnique->user_id     = $user_id;
           $procurementUnique->company_id  = $request->company_id;
           $procurementUnique->product_id  = $product_id;
           $procurementUnique->productname = $request->productname;

           $procurementUnique->ttt_description    = $request->tankerTotankerDesc;
           $procurementUnique->tto_description    = $request->tankerTakeOverDesc;
           $procurementUnique->cif_description    = $request->costFreightInsuranceDesc;
           $procurementUnique->fob_description    = $request->freightOnBoardDesc;
           $procurementUnique->optional_procedure = $request->optional_procedure;

           $procurementUnique->ttt_price    = $request->tankerTotankerPrice;
           $procurementUnique->tto_price    = $request->tankerTakeOverPrice;
           $procurementUnique->cif_price    = $request->costFreightInsurancePrice;
           $procurementUnique->fob_price    = $request->freightOnBoardPrice;
           $procurementUnique->optional_procedure_price = $request->optional_procedure_price;

           $procurementUnique->business_type    = $request->business_type;
           $procurementUnique->save();

            return redirect()->route('productUniqueCreate', $product_id)->with('message', 'Record successfully created');
        }
    }

Your problem is with this line..

redirect()->route('productUniqueCreate', $validator)->with('message', 'Record successfully created');

Remove the $validator.

redirect()->route('productUniqueCreate')->with('message', 'Record successfully created')->withErrors($validator);
