[SOLVED] Markup conditionally output based on template variable

Hello all,

I have a chunk which is used as a Ditto template:

<dt>[+pagetitle+], <a rel="external" href="[+authorurl+]">[+description+]</a></dt>
<dd><blockquote>[+content+]</blockquote></dd>

The parts in red I would like only to appear if my authorurl template variable has a value.

How do I go about making this the case? I think I need to use a snippet, but feel like I need some guidance. Many thanks.

Check out PHx

examples here (though not with Ditto):

And here’s a snippet approach

Thanks for the pointers. I’m trying the PHx route as it seems that could be useful to know about in future.

My Ditto call:



’testimonial’ chunk (my Ditto template):



[*authorurl*] is a template variable (url) which may or may not have a value.

{{testimonialauthorwithlink}} chunk:


{{testimonialauthorwithoutlink}} chunk:


However, I’m not getting anything appearing, whether or not the authorurl template variable has a value.

Can anyone see where I may be going wrong?

Not sure what to try next, so if anyone can suggest something I’d appreciate it - thanks.

David,

I’ve tested your code and it works fine except for two things:

1. The TV value returned is not the individual children documents’ but the parent document’s - so, using your example ditto call, the parent’s (document 6) TV value is returned for all the displayed documents. I suppose you want the children documents’ TV value returned.

By the way, why do you need the chunk {{testimonialauthorwithoutlink}}? I ask since if the TV is empty, there’s no url so why display [*authorurl*]?

2. [+description+] - does not return anything even when the field is not empty

Now, I have never used ditto so I know just very basic stuff about and don’t know about the [+description+]

What version of Ditto are you using? There’s a version from which PHx comes with Ditto so no need for a separate install. I’ll let the gurus weigh in on this...

cheers/k

IANAG, but I think PHx can be applied to what was stated in the original post quite simply: I view the "phx" pseudo-placeholder as a last resort.

[+description+] works for me in a Ditto template chunk - reproduces the Description field of the document in question.

Thanks for the insight. Not only wasn’t [+description+] not working but I kept getting parse errors on the front end ..something about prePHx not found in one of the ditto files.

Tried your code and it worked a treat - the correct TV values are output plus the {+description+]. Brilliant! David will be happy

cheers/k

EDIT: Getting the errors again:

Fatal error: Class ’prePHx’ not found in C:\wamp\www\modxtests\assets\snippets\ditto\classes\ditto.class.inc.php on line 329

It’s not important to me since was testing this for David but an answer to this issue might help someone else. Thanks

Thanks a lot guys - it’s working fine, and I’m sure I’ll use this method again and again in future. Here’s what I have now:

There will always be a testimonial author assigned to the entry, but not always a url. {{testimonialauthorwithoutlink}} was just `[*authorurl*]`, and in writing this reply I’ve just realised that it should have been `[*description*]` instead (which provided the author). I could’ve just put `[*description*]` straight in without using another chunk.

Thanks again for the great help.
