Call Snippet from chunk with parameters

Hi,

I’m using ditto to output some documents through a chunk. Ditto doesn’t seem to allow me to truncate specific placeholder text so I thought I’d just call a snippet from within the chunk and do my truncating from php. But so far while the call to the snippet works I can’t figure out how to pass it the text.

Example chunk below.



Thanks for any help.

Try with backticks not single quotes

Yes I tried that before.

This causes the snippet call to fail and the chunk just displays:

[[truncateText? &truncText=`content text here
` ]]

"content text here" being the placeholder text.

I don’t see why what you’re doing shouldn’t work (especially with the back-ticks in place), but what about sending the document ID (e.g. &docID=`22`) in the snippet call instead of the content itself.

Then your snippet code could do this:


Alternately, you could just fill in the summary field for each document. Make it a truncated version of the content (you could write code to automate this) and then use the summary TV instead of the content TV.

Thanks Bob,

I managed to pass the doc id but not the way you suggested. I had to drop the quotes:



Using id works this way because there are no spaces in the document id, but if there are spaces in the passed variable the call fails. This is fair enough but, why do any form of quotation marks cause the snippet call to fail?

That should be backticks `...` not any kind of quote marks.

By any kind of quote mark I included back tics `...`

It makes no difference using back tics, the call still fails in the same way.

You might call the snippet uncached.

Yes I tried this too.



Is the response. So the snippet call fails.

But don’t worry I took BobRay’s initial sugesstion and just passed the document id. It doesn’t contain spaces so doesn’t need to use back ticks.

Thanks!

I don’t know enough about MODx’s inner workings to be sure, but I think passing the document ID will also be a little faster and put less demand on the server than passing the entire contents of the document as a parameter.
