Getting all variables

[93-interactive]

Hi,

i am using h2o for a new cms and for the plugin system it is necessary
to get all variables in the template.

I have solved this so far by scanning through $h2o->nodelist->list and
get everything which is a instance of VariableNode.

Unfortunately this only works for templates not extending other
templates.

For now i solved this by getting all instances of Extends_Tag and then
create a new h2o object and scan for instances of VariableNode there.

This is not good, as for every extension i have to create a new h2o
object, is there a simple way to get all variables in a template,
including from parent templates?

Hello there,

H2o_Context object is where you want to look at, it holds all the variable in the template. You will be able access a instance of context object in any Tag class, look for the render methods "render($context)".

Thanks

thank you, unfortunately i think i did not understand.

If i var_dump $h2o->context, before rendering it is null, so i tried
the following:

$context = new H2o_Context($h2o->defaultContext(), $h2o->options);
var_dump($context);

Still i did not find where the variables are to find.
