Appendr is a small plugin to allow template strings to be changed in child templates., (*2)
$ composer require vierbergenlars/appendr:*, (*3)
Register the extension with your Twig environment, (*4)
<?php
// ...
$twig = new Twig_Environment($loader);
$twig->addFunction(new \Twig_SimpleFunction('headTitle', new \vierbergenlars\Appendr));
// headTitle is just an example name, you can name it anything you want.
<!DOCTYPE html>
<html>
<head>
<title>{{ headTitle('Website Name') }}</title>
{% do headTitle().setSeparator('~') %}
{% do headTitle().setDefaultAttachOrder('APPEND') %}
</head>
<body>
{# ... #}
</body>
</html>
{% extends 'base.twig' %}
{% do headTitle('Page name', 'PREPEND') %}
All methods are chainable (except the getters)., (*5)
Assuming headTitle is an instance of appendr., (*6)
headTitle().append('Title') (Same as headTitle('Title', 'APPEND') )headTitle().prepend('Title') (Same as headTitle('Title', 'PREPEND') )headTitle().set('New Title') (Same as headTitle('New Title', 'SET') )headTitle().getSeparator()headTitle().setSeparator('~')headTitle().getDefaultAttachOrder()headTitle().setDefaultAttachOrder('APPEND') (Also 'PREPEND' and 'SET')headTitle().getPattern()headTitle().setPattern('_/°° %s °°\_') (printf syntax, the pattern is used for each part that is added)Default options can be passed when registering the Twig function., (*7)
<?php
use vierbergenlars\Appendr;
// ...
$twig = new Twig_Environment($loader);
// Set default options in the constructor. (null skips an option)
$appendr = new Appendr('~', '_/°° %s °°\_', Appendr::APPEND);
// And register the Twig function
$twig->addFunction(new \Twig_SimpleFunction('fancyTitle', $appendr));
// Or set them on the instance later
$appendr->setSeparator('~');
$appendr->setPattern('_/°° %s °°\_');
$appendr->setDefaultAttachOrder(Appendr::APPEND);
