Hi I got inspired by this and created a very basic module to have these actions available in Rules http://drupal.org/project/rules_switch_user What do you think? Regards, mimo On Tuesday 22 Jan 2013 15:00:38 Lluís Forns wrote:
Ok.
Till now I have created a pair of actions; one which I call at the start of my rule to impersonate "node changing user", and one at last to change back. Using this I can call scheduled rules with the user who triggered them. It is all I need to the moment, so I will stop looking further into batching actions (limited time).
Thanks.

drupal_static() is not equivalent to PHP static. The example you've given is using PHP static and yes, it will not be available in another function.

I know we are going OT, but I also want to understand this;
what about:
function mymodule_complex_calculation() {
static $cache; if (isset($cache)) {
return $cache;
} // Otherwise we need to perform our calculations // ...some complex calculation that returns $cache = complex_calculation(); return $cache;
}

You are saying that if I instantiate a variable in
"mymodule_impersonate()"
it will not be available in "mymodule_unimpersonate()"?

You "think" wrongly. A static variable has local scope to the function declaring the static variable.

I think static are also available to other functions, use them to
store
cached information across my code and they work.

Static variables are only saved for a single function. Global
variables
are available to all functions during a single page request. Session variables are available to all page requests during a session.

Darren, thanks for the link. What is the difference between using global or static to save the data?
