Hello all,

because I just don't know where and what to search for:

What hook (or similar) can I use, if I want to verify/modify data entered
into a content elements BE-Form before it is saved?

Detailed example: If the user uploads a file as part of the content element
I want to fill the file size of that file into a db field automatically
instead of letting the user enter the data. But how to hook in?

And as add on: How do I define which data of a content element is shown in
the summary when WEB/PAGE is selected, i.e. in the list of content elements
in column normal?

Thanx in advance,
--

You need to search in t3lib/class.tcemain.php. Look in function named
process_datamap(). You will find at least three hooks there. All of them
accept parameters from record array. But examine the functin carefully
because parameters may have unexpected values to you (like negative pid,
which is not a pid but a pointer to another content element, etc).

Thanx for that great pointer, somehow I think I begin to understand
something more....

One add-on:

Setting a hook works fine up to the point where I discovered that the
return of the hook function isn't used by the caller at all. I want to
modify/set the value of a field that then should be shown in the form as it
would have been entered, but when I set $incomingFieldArray['field'] in my
function, the process_datamap() doesn't care.

Is there a way to modify $incomingFieldArray in the way I would like?

Maybe important: More detailed the thing I miss is that the data I set (and
which can be verified even in the post-Hook doesn't get shown in the form.
How can I achive this?

i use processDatamap_afterDatabaseOperations hook
and in my function i reference the variables :
processDatamap_postProcessFieldArray ($status, $table, $id, &
$fieldArray, &$pObj)

this way i can modify and add data to the field array, since i reference
the pObj variable, i use it to return warning and errors to the editor

hope this helps,

Serge

Oh yes,

If you want data stored in fields not editable by the user, define them
in the tca, but do not put them in the types array, i have used it this
way and works like a charm, or better, put them in the types array, but
dont give none admins access (using "exclude" => 1 in the tca)

The thing I struggle with is, that as soon as I set the type in TCA
= "none" to make it read-only the datafield seems not to be processed by
that hook anymore. I tested it several times and could reproduce it.

So setting it to admin only might give the same result, but I would call it
a hack only.

Anyway, thanx for your help.
