Proof of concept for toggling tv groups with a select TV in MODX.

readme.md

This plugin has a dedicated repository now. You can find it here:

https://github.com/pepebe/toggleTVSet

I'll listen to bug reports and any advice that comes around.

In ther future this will hopefully develop into a proper package that can be installed by the MODx package manager.

Thanks for taking interest in my work.

getTVLabel.snippet.php

<?php
/*
getTVLabel snippet for modx 2.3

Version:
------------------
v0.0.1 (2015-03-06 16:44)

Author:

Problem:
------------------
You have a selectTV with these input options: "Standard==4||Carousel==8||Cover==9,10||Jumbotron==5,6,7"
In your template you want 
* to use [[$[[*selectTV]]]] 
* to call [[$Standard]] or [[$Carousel]].

In this case you need the selected label instead of the current value.

This snippet will retrieve the label of the value you have selected.

Usage:
------------------------------------------------------
If your TV is not prefixed, use the snippet like this:
[[*Header:getTVLabel]]

If you are working in getResources/pdoResources, etc and your TV is prefixed (example [[+tv.Header]], etc.), use it like this:
[[+tv.Header:getTVLabel=`tv.`]]

getTVNames.snippet.php

<?php

/* 
Output filter to retrieve names of TVs from a list of TV ids
[email protected]

Idea:
Use it with toogleTVSet plugin (included below) to handel different template options.

Usage:
This is a simple output filter. 
You can use it in snippets like getResources or pdoTools to add TVs to your query:

Example:
&includeTVs=`[[*Header:getTVNames]]`

*/

$tvNames = array();

$tvIds = explode(',' ,$input);

foreach($tvIds as $tvId){
    $tv = $modx->getObject('modTemplateVar', $tvId);
    $tvNames[] = $tv->get('name');
}

$tvNames = implode(',',$tvNames);

return $tvNames;
