[Resolved] Preg warning message: Compilation Failed

[gcohen]

I ran what I think is a pretty standard regex, but when no match is found, I get the following error. When there is a match, the error doesn't appear. Any ideas?

Warning: Compilation failed: nothing to repeat at offset 1 in filename.php on line 61

The code is below:

$regex = '/^' . $arrayGetScale['Validation_String'] . '+$/';
	if (!(preg_match($regex, $_REQUEST[$questionID]))) {
		reportError($sis_root_path, "One or more questions were answered improperly.");
	}

Thanks for your help.

Your $arrayGetScale['Validation_String'] variable is blank or null. That gives you a regex like this:

/^+$/

The + thing needs something to repeat, but there is nothing, so you get that error.

Ah, stupid mistake on my part. I had several textboxes on the form, and it would run the above code for each one...but only some had $arrayGetScale['Validation_String'] values.

Thanks for your help.
