How to pass variables to Anonymous method in Laravel-CodePudding

I want to pass the request parameter to the method, but i fail every time. I am beginner in PHP.

public function changeModel(Request $request)
    {
        $u1 = $request->U;
        
        Schema::table('planspieldatas', function (Blueprint $table) {
            $table->renameColumn('U1', $u1);
    });
    
        Artisan::call('migrate');
        return redirect('/pssettings')->with('success-upload', 'Daten für Markt'.$u1);
    }

I am not able to pass the $u1 variable to the Schema::table method. Is there any option to change the coloumn names in sql from the front end.

CodePudding user response：

You are using Closure method so you need to use use() method to pass variables like

Schema::table('planspieldatas', function (Blueprint $table) use ($u1) {
        $table->renameColumn('U1', $u1);
});
