grab TV value and conditionally output formatted TV values

Hiya,

I have created a TV called "offer-categories", this TV outputs checkboxes that are assigned to a template used to create venue homepages. Each venue can belong to more than one offer category.

I need a snippet that can grab values from TV’s on the venue template. So I need to grab [*offer-categories*], the logo path from [*venue-logo*] and the value from the first offer [*venue-offer-1*] and also the page ID for the venue in Modx.

I then need to output these values on an offers index page thus:

<h2>Category: Dining</h2>

<ul>
<li>
<a href="[~id~]"><img src="[*venue-logo*]" alt="[*pagetitle*]" /></a>
<h3><a href="[~id~]">[*pagetitle*]</a></h3>
<p>[*venue-offer-1*]</p>
</li>
</ul>

There are about 70 venues and they are all assigned to one or more of 5 offer categories.

So the logic is:

Where Ultimate Parent id = 15 > (venue category container) search through child items (venue pages) + where offer-categories TV = Dining
Grab the above mentioned TV values and output each record set in formatted html

Elseif offer=categories = Food To Go
Grab TV values....

I’ve had a look at the getTV function though I’m struggling to adapt it for my needs.

Could anyone lend a helping hand?

I think you can use Ditto together with the getField-snippet
If you have a TV in your ultimateparent ’category’

use Ditto with something like that:

together with getField which should return the category of the ultimateparent:

I’m not sure if this works, but something like that should do it.

Thanks Bruno,

From your code I’m still wondering how I would grab the various TV values. Would it be something along these lines?



So the above seems to say, where parent id=15, get all child item fields (pagetitle,alias,venue-logo,venue-offer-1) where TV offer-categories = Dining. And then format the output as per the template file.

offer-format tpl:

The penny finally dropped. I can do this with a pure Ditto solution as suggested by Bruno. I wasn’t aware that Ditto could grab custom template variable values without the help of something like getField.

Anyhow this is the Ditto call I’m using and the same tpl as above:



Thanks for your help.
