Hi there,

Running Revo 2.1.3pl.
Have a blank template:

[[!testing1234]]
[[*promo_title]]

Code in testing1234:

$hello = $modx->resource->getMany('TemplateVars');
foreach($hello as $failtown)
{
    echo '<p>Name: '.$failtown->get('name').'| Value:'.$failtown->get('value').'</p>';

}

First time the page runs I see all TV's printed, and I see the last TV promo_title printed also.
A cache file is generated.
When I press F5, I get a list of all the TV's, but the values are blank!!! Whats weird is the promo_title is not. It has a value.

Problem: Why are the TV's available in a template, but blank on the second load when I query them in a snippet?!?
Have I gone mad?

Hi
Did you try to simply call your TV uncached ?

[[!testing1234]]
[[!*promo_title]]  // just put an exclamation mark at the start of the call to make it uncached

Not sure it solves your problem, but I think it could be a part of the problem....

And to answer your question, yes TVs are avalaible in templates (they are TEMPLATES Variables after all)...

Cheers

If I call the snippet cached...its fine....but thats not what I want!! I need to get the latest code from the Db each time...it fails after the first fetch?!?!

You want the following to get the raw TV value in the Snippet:

$failtown->getValue($modx->resource->id);

Or this to get the fully processed output as would be rendered by the TV tag:

$failtown->renderOutput($modx->resource->id);
