I'm using the Textile plug-in on a new project and it's spawning PHP errors all over the place and complaining thusly:

A PHP Error was encountered Severity: 8192

Message: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead

Filename: textile/pi.textile.php

Line Number: 918

Not one I've run into before but this is occurring in my local dev env on a new MacBook so it's a fresh install of MAMP running PHP 5.5.3.

Any ideas???

Update: I only see the PHP error in the front end templates when logged in as Admin.

The function generating the error is 'footNoteRef':

function footnoteRef($text)
    return preg_replace('/(?<=\S)\[([0-9]+)\](\s)?/Ue',
        '$this->footnoteID(\'\1\',\'\2\')', $text);


  • As I just tweeted to you - could you post the function where this is occurring. – madebyhippo Dec 6 '13 at 11:44
  • There you go. It's 'footnoteRef' that's throwing the error. – Nathan Pitman Dec 6 '13 at 11:53

According to http://uk1.php.net/preg_replace , the /e modifier was removed in PHP 5.5.0 . If you downgrade PHP to pre-5.5.0, then the error will go away. Alternatively, in your config.php file set error_reporting(E_ALL ^ E_DEPRECATED); to hide deprecated warnings.

Alternatively, upgrade Textile - but it looks like http://devot-ee.com/add-ons/textile-editor-helper-teh hasn't been upgraded in some time.

=== Added after you posted the code ==

Try changing

function footnoteRef($text)
    return preg_replace('/(?<=\S)\[([0-9]+)\](\s)?/Ue',
        '$this->footnoteID(\'\1\',\'\2\')', $text);

to (untested)

function footnoteRef($text)
    return preg_replace_callback('/(?<=\S)\[([0-9]+)\](\s)?/U',
function ($matches) {
            return $this->footnoteID($matches[1],$matches[2]);
  • Hoorah, this worked out the box. Thanks Richy. – Nathan Pitman Dec 6 '13 at 12:08

So, if you remove everything from the function as it is and replace it with the following:

                   create_function('$matches','return $this->footnoteID($matches[1],$matches[2])'), $text);

This is totally untested, but I think it's right. No doubt if it's not, someone will chime in - Regular Expressions are not my forte.

  • Didn't work for me, I got another PHP error but thanks anyway. Pretty sure it's just missing a character here or there. :) – Nathan Pitman Dec 6 '13 at 12:09
  • Whats the error? – madebyhippo Dec 6 '13 at 12:13
