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.
