Twig: Slug with Regex in Twig?

Question

I want to slugify a value, for example "slugName = Spain & Italy"

When I make my slug in TWIG {{ slugName|slugify }}, the result is Spain_amp_Italy

Is it possible to set a REGEX in Twig, so that my "&" for example will be translated in "and" ? THANKS

Consider making your own twig filter: http://symfony.com/doc/current/cookbook/templating/twig_extension.html It's a useful skill to master and will let your slugify exactly how you want. Hint: Take a look at twig's slugify source code. — Cerad, Apr 16 '15 at 15:15

You could concatenate multiple filters, and use a simple function replace():

{{ slugName| replace({'&': 'and'}) | slugify }}

Yes, I've tested it with a string. Could you check what's the value of `slugName` for you? – Alessandro Lai Apr 16 '15 at 15:01
When I make {{ '&tt&'| replace({'&': '-'})|slugify }} the value is "tt" – Zwen2012 Apr 16 '15 at 15:06
That's because `slugify` removes trailing and starting spaces or `-` – Alessandro Lai Apr 16 '15 at 15:26

You can create a custom function to do this

<?php
$twig->addFilter(new Twig_Filter('ampersand_to_and', function( $string = '' ) {

    return preg_replace('/(&amp;|&)/m', 'and', $string );
}));

and then you can use it as follows:

<p>{{ 'Spain & Italy'|ampersand_to_and }}</p>
<p>{{ 'Spain &amp; Italy'|ampersand_to_and }}</p>
