README

Adds PHP's preg_replace function as a Twig filter.

Requirements

This plugin requires Craft CMS 3.x or 4.x

Installation

To install the plugin, follow these instructions.

1. Open your terminal and go to your Craft project:

cd /path/to/project

1. Then tell Composer to load the plugin:

composer require emandiev/regex-replace-twig-filter

1. In the Control Panel, go to Settings → Plugins and click the “Install” button for Regex Replace Twig Filter.

Usage

{{ entry.heading|preg_replace('~pattern~', 'replacement') }}

Any backslashes in the regular expression must to be double-escaped \\ to work properly.

How is this different from Craft's replace filter?

In short, the preg_replace filter offers a more direct call to PHP's preg_replace function.

Craft's filter allows for both normal string and regex replacements but slightly limits the regex replacement functionality.

Example 1

preg_replace allows you to use any delimiter, while replace works only with forward slashes /.

{{ entry.heading|preg_replace('~pattern~', 'replacement') }}

Example 2

The replace filter performs str_replace when an array is passed and always ignores the $limit parameter.

preg_replace binds all it's parameters to PHP's function.

This allows you to pass arrays for the $pattern and $replacement parameters, and an integer for the $limit parameter.

{{ entry.heading|preg_replace(['~pattern1~', '~pattern2~'], ['replacement1', 'replacement2'], 3) }}
