Cold Fusion String Function LEFT placement?
I'm trying to use the LEFT(string,count) function in Cold Fusion to concatenate a longtext MySQL display on a page. However, I do not like the variable results because I set a specific character count versus it concatenating at a paragraph break or end of a sentence.
ie: If I have a longtext database field that is 500 characters long and includes paragraph breaks and I only have room on my page to display 75 characters (for design purposes) before I create a link to display the remainder of the text (e.g. <read more>), I want the break of the character to not be mid word or mid-sentence BUT also not to exceed the 75 characters. In other words, I want it to stop at the end of a sentence BEFORE 75 characters.
Because every record has variable characters, i can't simply do a specific character search other than a period with a space following it.
I need the best (least) code to have it analyze the database field results and stop the display per the above.
My current code is:
#Left(ParagraphFormat(desc
which produces broken words with the ellipses following (which is okay)

you can try counting words and display the only one that you need . read thishttp://www.coldfusionjedi.com/index.cfm/2007/8/2/Counting-Word-Instances-in-a-String

azadisaryev:
The "abbreviate" UDF works... except it gets rid of my PARAGRAPHFORMAT function... which i need.
My code is:
#abbreviate(ParagraphForma
It displays properly without breaking any words, but it ignores the database carriage returns... which I want. Any ideas?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
BTW: The reason it didn't work is that the udf abbreviate() removes html tags. So when you call it _after_ ParagraphFormat(), it removes the <p> tags that ParagraphFormat() just added...
^^^ yep, what _agx_ said - switch the functions around.

Thanks for the points. But in all fairness - Azadi was the one who suggested the UDF in the first place. It seems fair that he get some of the points ... ? :)

since I already awarded points (my mistake for not seeing the original post) how do I change it after the fact?
Isn't there an option for "Request Assistance" or "Reallocate"? (Sorry, I dont' ask questions on EE much. So I'm not sure)
