TangoMan Callback Twig Extension Bundle
=======================================

[](#tangoman-callback-twig-extension-bundle)

**TangoMan Callback Twig Extension Bundle** provides simple callback function for twig which avoids unnecessary callbacks to stack up indefinitely in users query string.

🧩 Purpose of the `Callback` Class
---------------------------------

[](#-purpose-of-the-callback-class)

This class defines a Twig extension that introduces a custom function called `callback`. Its main job is to **generate clean URLs** by **removing `callback` parameters from query strings**, which can help avoid issues where multiple callbacks get appended indefinitely and make sure users query parameters are not lost in the process.

🔧 `callbackFunction()`
----------------------

[](#-callbackfunction)

```
public function callbackFunction($route = null, $parameters = [])
```

- **Behavior**:
    - If no route is provided -> use the current request URI.
    - If a route is specified -> generate a full URL using Symfony's router.
- **Core logic**:
    - Parses the URL.
    - Removes the `callback` parameter from the query string.
    - Reconstructs and returns the cleaned URL.

✨ Real-Life Use Case
--------------------

[](#-real-life-use-case)

Imagine you're building a redirect system where callbacks are passed through URLs. If multiple redirects occur (e.g., login flow, third-party auth, or form submissions), you might get URLs like this:

```
https://example.com/page?callback=https://another.com?callback=...

```

This class avoids that endless loop by **stripping the `callback`** query parameter from the final URL so it stays nice and tidy.

📦 Installation
==============
