Installation

1. Add dependency with composer

2. Register the bundle in your Kernel

How to use

First select the annotation you want to use and add it to your controller action, you have to provide form class and parameter name, also parameter has to have a type.

While FOSRestBundle is not dependency, my examples are with FOSRestBundle and this is mainly used with it.

Before:

After:

The Request enters controller action only if everything in form is valid, else it will return validation errors.

Annotations

There are 3 options you can set when adding annotation to your action:

• formType - FQCN of your form type.
• parameter - parameter name you will be using in your action. (parameter has to have a type)
• clearMissing - if some value is not sent this will by default set it to null for POST/PUT but for PATCH this value will be ignored. You can control this on your own if you want.

Post

In POST we take your parameter and from type you provided. We create new Object and populate data from Request and if everything is valid we populate the parameter in your action and we let Request enter your action else we return form errors.

Patch/Put

Here we depend on Symfony ParamConverter and we expect that the parameter you provided is already a populated object. If you add {id} parameter to your route and type-hint it with Doctrine Entity, Symfony ParamConverter will already do that. If everything is valid we let Request enter your action else we return form errors.
