regex_replace

A regular expression search and replace on a variable. Use the preg_replace() syntax from the PHP manual.

Basic usage

{$myVar|regex_replace:"/foo/":"bar"}

Note

Although Smarty supplies this regex convenience modifier, it is usually better to apply regular expressions in PHP, either via custom functions or modifiers. Regular expressions are considered application code and are not part of presentation logic.

Parameters

Parameter Position	Type	Required	Description
1	string	Yes	This is the regular expression to be replaced.
2	string	Yes	This is the string of text to replace with.

Examples

<?php

$smarty->assign('articleTitle', "Infertility unlikely to\nbe passed on, experts say.");

Where template is:

{* replace each carriage return, tab and new line with a space *}

{$articleTitle}
{$articleTitle|regex_replace:"/[\r\t\n]/":" "}

Will output:

Infertility unlikely to
be passed on, experts say.
Infertility unlikely to be passed on, experts say.
