[development] #just_before_validation ?

[Bèr Kessels]

Hi,

I am looking for the following: I want to generate the title of a node from 
content in that node. 

Hence I need to hook into the node submission on several places.

First: hook_form_alter, to make the title field hidden
Then just *before* validation to capture the node content and fill a title. So 
that all possible validation hooks can still run, but that the title has a 
value.

Any idea what kind of hook, or #callback I should be looking at?

#validate is not a good option, since I think it is important to run all the 
normal validations on that title field. But maybe the trick is to set that 
#validate, and inside that callback function fill the title value and then 
call all the validation hooks from there? I am personally not a fan of using 
validation to cahnge values. Validation is for.... validation. 

Also important is, that this needs a POST, because I have to grab info from 
that POSTed node.

Bèr
