Action Hook Chaining

[tomdchi]

Is it possible to execute a action hook from within another action hook? Example would be if I needed to use the InvoiceCreationPreEmail hook but only during cron run where I would use the DailyCronJob hook.

Or is there any other way to have the InvoiceCreationPreEmail hook only execute during cron run?

I think all of the functions that are set as hooks are available, so couldn't you just call the function you want to run from within the cron hook function?

I thought about that as well, but it all depends on what order it runs in. I kinda have a feeling it will not work like that. The best solution would likely to be to hook into the InvoiceCreationPreEmail and find a way to determine if the cron is running or not. A quick hack would be to just check to see what the time is.

Well perhaps. It is easily tested with a few debug statements and the use of PHP's get_defined_functions().

 

Failing any of that, perhaps you could just use an include_once statement to ensure the correct hook file is included and then call the function.
