Unknown modifier '6' in /includes/modules/additional_images.php on line 48

[scottmcclean]

Hi all,
I am getting the following error but am not sure why....

PHP Warning: preg_match() [<a href='function.preg-match'>function.preg-match</a>]: Unknown modifier '6' in /includes/modules/additional_images.php on line 48

The corresponding code on line 48 is:
if(preg_match("/" . $products_image_base . "/i", $file) == "1") {

Can anyone point me in the right direction as to what the "unknown modifier" is?

many thanks

You've probably got an image whose filename contains characters which are confusing the regex, such as apostrophes or square brackets or parentheses.

See the Similar Threads section below for some related discussion.

Thanks DrByte,
firstly, apologies for late response. I have gone through the images and I did find one or two that did contain parentheses. But I am now getting another type of warning:

preg_match() [<a href='function.preg-match'>function.preg-match</a>]: Unknown modifier '3' in /includes/modules/additional_images.php on line 48.

I cannot figure this out...however, is this a "major" problem that needs to be tracked down and fixed, or is there a way to suppress these debug files - I am getting them every couple of minutes and have to keep clearing down the cache every other day.

I would really appreciate your steer on this.

Other than letters and numbers and periods, why are you using other symbols in your image filenames? Is there any reason why you can't change that?

[scottmcclean]

The only other symbols that i Can see are the underscore "_" and some hyphens (-).

I will go through and change these to see if that is the problem.

Many thanks

You could change that line to say this instead (taken from v1.5.0beta):

 if(preg_match('/\Q' . $products_image_base . '\E/i', $file) == 1) {
