Stopping this "uuuuuuuuuuuuuu"

[Kaplanconstruct]

I have a textarea in my form and I'm trying to stop users from entering long lines of text with no spaces. If they do, it expands my table off the page. I havent found away to make the line break within the table. I need some server side technique for assuring that a user uses spaces. So if a word is long than say 30 characters with no space I want to reject the post.

Any ideas? Thanks in advance!

I would also like to stop repeat characters in a row, like uuuuuuuuu. If anyone has an idea on how to stop that

[Newsgroup_User]

treat the user's text as a list with multiple delimiters - space, comma,
fullstop, colon, semi-colon, exclamation mark, question mark, etc - and
apply appropriate cf list functions to it to check the input for long
words and words with multiople repeated characters, though i would
probably not bother with the latter one myself...

Azadi - I have looked through all the list functions and cant come up with a combination that will work to resolve my issue.
I would assume it would be a function that would look for a space and count characters after that space. Do you know of a cf function that will do this? Thanks

i was meant to edit my email to say just "functions" instead of "cf list
functions" before posting, but thn forgot... sorry....

what i had in mind was simple loop over multiple-delimiters-list and
check length of each list element.

I wrote a blog entry on this awhile back using a built-in JRun class file. It may help you.

Hi,

Try this 'differentChars' udf.

http://cflib.org/udf.cfm?ID=994

You can determine the bogus entry by the occurances returned by this udf.

Are you also trying to keep users from entering URL addresses? Because these can easily be longer than 30 characters. If you break these up the link most likely won't work. Just thought I'd throw that out there...

Thanks everyone!

Yeah CFMXPrGrmR youre right I would make it a lot longer than 30.

C_wigginton, I checked that blog out and it looks like that wordwrap is what I'm looking for I'm going to give it a try tonight.

Daverms that udf looks good if I dont use it for this I'm definitely going to use if for passwords.

Azadi yeah now that I'm thinking about it I'm not sure its worth messing with the repeat characters, at least for this part.

The easiest way would also be very basic. Loop over the content as a list with a delimiter of " " (space). Any other delimeters would not necessarily tell you if there was a long word because it could be part of the long word like uuuuu,uuuu

Then check the length of each part of the list.

So something like this:

<cfset test = "A BC DEF HIJK LMNOPQ">
<cfset tooLong = false>
<cfloop list="#test#" index="x" delimiters=" ">
<cfif LEN(x) GT 30><cfset tooLong = true></cfif>
</cfloop>

You could throw in there some code to check if it is an email address or URL very easily. And of course you would change "test" for your variable.

Dinghus - thanks for the sample! I think that should work perfectly
