Adding fields with Datamanager?

[endquote]

In the vB announcements forum, it says: "Naturally, plugins can attach themselves to the data managers, allowing you to add code that runs before or after saving, or even to add new fields."

Has anyone figured out the add new fields bit yet?

Nope, as far as I can see you have to hack the DM class(s) to add new fields, if this is not the case then someone please tell me how to do it, because I have had to do it this way.

For every Datamanager there is a name_start Hook where you can add custom fields.

Example for the User Datamanager :
Hook: userdata_start
Code:

PHP Code:

$this->validfields['myfield'] = array(TYPE_STR, REQ_NO, 'if ($data != 'notallowed') { return true; } else {return false; }')); 


This adds a new field myfield which is not required and will accept strings other then 'notallowed'.

Awsome. Now the question is, do many areas of vBulletin use data managers?

Actually, this doesn't work. I had to change it to this ;

$this->validfields['myfield'] = array(TYPE_STR, REQ_NO[high], 'if ($data != 'notallowed') { return true; } else {return false; }')[/high]);

With the highlighted bit being optional (and not used by me).

Right. Slight mistake on my end.
But at least I was willing to post the correct code

Of course the fieldname must be the key.

Finally got some license issues sorted out so now I can view the code. I basically got it once you pointed out that hook in the constructor though.

Another question would be... I don't suppose there's any way to automatically add fields to the actual db tables with a plugin? At least not without checking if the field was there every time your DM ran, which would be dumb. Can that be done with the "plugin definitions xml file"? I haven't really looked into that yet.

Sounds like you'll have to get the user to manually run an install script or query unfortunatly.

Its a good idea to be able to add "run once" queries though.
