Question

I keep getting this error:

Warning: preg_match()
[function.preg-match]: Unknown
modifier ‘t’ in
D:\xampp\htdocs\administrator\components\com_smms\functions\plugin.php
on line 235

on:

$PageContent = preg_replace($result->module_pregmatch, '', $PageContent);

I do a var_dump on the $result->module_pregmatch and I get the following:

string '/<title>(.*)</title>/Ui' (length=23)

string '/<meta[^>]*name=["|\']description["|\'][^>]*content=["|\'](.*)["|\']\s*\/>/Ui' (length=77)

Can someone please tell me what I’m doing wrong? I’ve been stuck on this error for way too long…

Answer 1

You are using forward-slashes as your regex pattern delimeter, so /<title>(.*)</title>/Ui' will not work (</title> has a forward slash).

You should be able to escape the forward slash or use a different delimiter that is not contained within the pattern, for example

'/<title>(.*)<\/title>/Ui' //(esacaping)

or

'~<title>(.*)</title>~Ui' //different delimiter
