@EVAL binding with Image widget TV

Hi

Simple stuff I am sure, I am using a TV to hold an image. easy.

But I also need the URL for the image. Having searched for a solution, Ryan Thrash reccomends using another TV and @EVAL binding to get the URL and simply calling a second TV when you need just the url and not <img src...etc.

But being new I dont know how to form the @EVAL binding

I am guessing it’s something like @EVAL return ([*imageTV*]) but cant quite get it to work.

Any help appreciated - thanks all

You’ll need to use the API function getTemplateVarOutput() for that.

Thanks - but if I have the image widget wont that mean the output of the tv is <img etc on not the url?

just trying to play with it now :-

@EVAL getTemplateVarOutput(’projectImage’)

There are other TV API functions, one of them should just return the content of the TV rather than its output.

thanks found getTemplateVar etc

still working on the syntax though...thats my biggest problem..

thanks for the help ;-)

Yeah, I didn’t give you any examples because I’m always stumbling through those by trial-and-error, then never think to actually make a record of what I did!

I know the feeling! best -

ok I have got his far, I am using the following @EVAL on a tv called projectImageURL



in the default value field of the tv.

But the document Identifer is being evaluated from the page on which I am calling ditto. How do I get the tv that the @EVAL is "filling in" (projectImageURL) to always reference the original doc itself - if you understand. SO that all

projectImageURLs come from projectImageMap on each doc?

Also from the array do I extract the image name:-



? thanks
