Regex Over Multiple Lines in DCT

Hello,

I am trying to validate user input in a textarea (multi-line). The Regex I have validates the first line the user enters but not any line after that. Is there a way to validate multiple lines in a textarea?

Here is my Regex.......
[0-9 a-zA-Z-_]+[,][0-9 a-zA-Z-_]+[[][0-9]+[]];

Thanks,
-Chuck

You can use the "m" option to span multiple lines in a regular expression. So, basically, the ^ would refer to the beginning of the search string and $ would refer to the end, as always, but the "m" provides multi-line support.

Thanks Dave,

How would the syntax go? I tried ......
[0-9 a-zA-Z-_]+[,][0-9 a-zA-Z-_]+[[][0-9]+[]];\m
&
^[0-9 a-zA-Z-_]+[,][0-9 a-zA-Z-_]+[[][0-9]+[]];\m?$
with no luck.

Are you doing it in Perl or in Javascript? Post your code in more context so I can get an idea of how you're using it.

This is in the DCT itself.

<textarea validation-regex="^[0-9 a-zA-Z-_]+[,][0-9 a-zA-Z-_]+[[][0-9]+[]];\m?$" required="t" cols="41" rows="4">

Oh, yikes. Okay, I don't think there's a way to do that, but you can certainly validate it on the FormAPI side and I THINK it'll accept the "m" option.

var re = new RegExp("^[0-9 a-zA-Z-_]+[,][0-9 a-zA-Z-_]+[[][0-9]+[]];","m");
if (!(string.match(re))) {
--- throw error and return false ---
}

In addition to the thread that Michael referenced you might also want to look at http://devnet.interwoven.com/site.fcgi/techlib/047665 (Note: the stylesheet for the KB articles unfortunately tends to use a rather-hard-to-read coloring for 'pre' formatted code - so you may need to copy the text and paste it into something else to read it)
