Hi There,
I am using your excellent 'Basic auto' template and have everything working including an RSS feed of the used bikes (as per instructions http://www.interactivetools.com/docs/cmsbuilder/rss_feeds.html).
However, there are 2 things I would like to be able to do:
1 - It is important for me to have an image with each item listed. I have tried all sorts of stuff but can't get it working. I know that I am very close as after following these instructions: http://www.interactivetools.com/docs/cmsbuilder/uploads.html) I can see the correct URL in the source! For some reason though it just isn't doing the last bit lol!
2 - Also is it possible to limit the length of a description to a certain amount of characters?
Many thanks in advance

Hi 8BG,
RSS feeds can be finicky, but this should work to display an image.
In general, any time you want to treat code as "code" in an RSS feed, you need to surround the code with CDATA tags.
Note: You'll have to add the URL to change the relative image thumbURLpath location to absolute.
As far as limiting characters, here are 2 excerpts from my CMSB Cookbook that may help.
DISPLAYING THE FIRST X CHARACTERS ON A LISTING PAGE
Add this at the top of the page or before you want to invoke the character limiting function:
and then where you want to display your content:
LIMITING THE NUMBER OF WORDS SHOWN IN A PAGE
If you use the character limiting function that’s exactly what you’ll get, and words can be cut off. But if you want to limit the word count, Dave shares his usual uncanny wisdom:
Put this code at the top of your page, or before you want to invoke the word limiting function:
Then put this code where you want the words limited (to 5 words):
Hope that gets you started.
Best,
Jerry Kornbluth

I am using the wysiwyg editor with barely any formatting at all but i do have several paragraphs. Limiting the words is making it all one paragraph. How can I keep my paragraphs?
Re: [rez] Show images in RSS feed / Also limited description length

Hi rez,
Do you mean makes it all one paragraph on the list page that is limited or on the detail page?
What does the source code look like with and without the limit words function?

Jerry

Hi rez,
Use this version of maxWords to keep your paragraph formatting.
Let me know if that works for you.

Hi Tim,
What is the nature of the problem you're encountering? If you could clarify what's happening and attach the .php file you're working with, I can take a look for you.
Hope this helps.

Hi,
What's happening is that you're outputting the content of your about record in two different places:
You're only using the maxWords function the second time. Trying changing the code to this:
Hope this helps.
