display a partial section

[brantGuy]

Im currently using

#Left(qGetArticles1.event, '50')#

to display a teaser for an event or an article...it just displays the first 50 characters...the problem with this is that it indiscriminantly cuts a word off anywhere...how can i ask it to go to 50 characters then cut the display off at the next blank space...

Appriciate any help...

Thanks

I use my old code for this still

listDeleteAt(left(qGetArticles1.event,50),listLen(qGetArticles1.event," ")," ")

But I kinda like Left(qGetArticles1.event,REFind('[[:space:]]',qGetArticles1.event,50)) now.

Thanks guys, worked like a charm....

 

[brantGuy]

can I use a similar technique to break a long article in to pages...

like display first 1500 characters, then look for paragraph break

at the paragraph break, insert link to new page.

 

[r937]

i don't see why not...

... but how do you detect a paragraph?

sure can

page 2 startPoint should be at 1500 + end of paragraph and end at startPoint + (1500 + endofparagraph)

paragraph is a tough one because it is not always the same...
