Hello!
Please tell how to use correctly property set in TV output render? How to retrieve properties in descendant of class modTemplateVarOutputRender?
Firstly I've created property set with required properties and wrote in content construction kind of [[*mytv@propset]].

The properties are mainly intended just to set placeholder values. If you can have your render class return the placeholders to display, MODX will replace them with their values.

If that doesn't work, you can get the property set directly (though it's discouraged):

$pSet = $modx->getObject('modPropertySet', arrray('name' => 'propset'));

if ($pSet) {
   $properties = $pSet->getProperties();
}

Another way to go would be to call a snippet:

[[!snippetName@propset? &tvName=`mytv`]]

The snippet could load your rendering class, get the TV value for a given resource, get the properties from the $scriptProperties array, and return the appropriate content.

Yet another option, would be to create System Settings rather than a property set. Then you can get their values in your class like this:

$setting = $mod->getOption('settingName', null);

The idea is to avoid using snippet and use tv output class as a snippet with parameters. In manager gui it is possible to attach property set to TV, but I can't understand how to extract these properties. sad

At the moment of invoking method

getObject('modPropertySet', arrray('name' => 'propset'));

name of property set must be known.

MODX will process this tag by getting the TV and replacing any placeholders in the TV that match keys in the property set before returning a value.

[[*mytv@propset]]

AFAIK, there's no way to hook into this process, and since a TV can have more than one property set attached to it, there's no way to get one without knowing the name.

You could call a snippet like this:

[[!MySnippet? 
    &propertySet=`name_or_id_of_property_set` 
    &tv=`name_or_id_of_tv`
]]

That way you could do whatever you want with the TV and property set.

It's difficult to advise you on this, since you haven't said what you're trying to accomplish and why. I suspect that a property set is not the best way to solve your problem.
