Execute only 1 POST function at a time

My problem is that I have 2 same routes for POST but each one of them is assigned to a different button.

If I run first form with action 'BuilderController@testing' everything works fine but other one 'BuilderController@postDB is giving me an error:

$image->getClientOriginalExtension();

Which is part of 'Buildercontroller@testing, so what I want to do is if I run @postDB ignore function @testing but if I run @testing ignore @postDB.

Blade:

@extends('layouts.master') @section('title', 'Website Builder') @section('content')
<meta name="csrf-token" content="" />
<div class=flex-container>
    <div class="flex-item templates">

        @foreach ($templates as $template)
        <a class="content-link" href="">
        <img class="template_img" src=""/>
        </a> @endforeach
