in thread Eugh, regex :(

Oops, just saw that! Changed it, still getting errors :(

It seems to be from this line still, cos if I comment it out - the rest of the script works fine:

$post_message =~ s|\Q[img]\E([\?\%\:\/a-zA-Z0-9_\-\.]+)\Q[/img]\E|[img]$1[/img]|sig;
(the above is just a more basic version of what I'm trying, to see if I can try and track down whats going on)

Driving me nuts :(

Cheers

Andy

    Ah, looks like you've stumbled into a perl parsing trap:

    s||$1[/|

    This code tries to interpolate the @1 array, the index starts with a slash, parsed as the begin of a matching pattern, but missing the closing slash, that's why you get the Search pattern not terminated error. Escaping the [ with a backslash should make all things fine.
