Paymill ideal scenario (for our webapp)

A user goes to the Profile area of my webapp.
The user then selects the tab Payment.
A form for collecting credit card data is shown in the user's Profile > Payment area.

The Profile > Payment form doesn't involve any transaction, it is just to "save" their credit card data (on Paymill servers, not ours) for later use, on future purchases on our webapp.

That way the user doesn't need to re-enter over and over his credit card deatils each time he wants to make a purchase, smoothing as much as possible the checkout process.

Procesando tarjetas de crédito en tu webapp: Paymill VS PayPal

TL;DR PayPal fatal. Paymill molamil.

Integración del proceso de checkout

PayPal no ofrece en España un método de pago que se integre por completo con tu webapp. La integración más básica Pago estándar consiste básicamente en redirigirte a PayPal e introducir ahí los datos de tu tarjeta. Es decir, la clásica página estándar de checkout de PayPal, con su típico look & feel.

La alternativa algo más avanzada, Pasarela integral, permite que en esa página externa de PayPal se pueda personalizar el logo... y algún que otro detalle (según PayPal "hasta 21 elementos gráficos").

	/**
	* PHP Regex to validate a Twitter hashtag
	*
	* Useful for validating a text input (an HTML form in your CMS or custom application) that must be a valid Twitter hashtag.
	* Valid examples: #a, #_, #_1, #_a, #1a, #áéìôü, #123hàsh_täg446
	* Invalid examples: #1, ##hashtag, #hash-tag, #hash.tag, #hash tag, #hashtag!, (any hashtag that is more than 140 characters long, hash symbol included)
	*
	* Regex explanation:
	* First, the lookahead assertion (?=.{2,140}$) checks the minimum and max length, as explained here http://stackoverflow.com/a/4223213/1441613

	function my_the_title($title) {
