$formValues field names

Question

Editing the work flow messages, I'm looking for the field names preceded by $formValues.
More specific I would like to include a line displaying the origin of the contribution in the work flow message "Contributions - Receipt (off-line)".
Where to find all the field names that can be used?

Answer 1

Without knowing on what form you are exactly, there is bound to be something like contributionId or contributionID in your form.

You can find the name in the $form object (try debugging the object for the specific name) and then use $contributionId = $form->getVar('_contributionID') to get the field and use it in your hook (assuming you are using a hook).
