Updating custom field values

[mcpacific]

I'm creating some custom modules that require Custom Fields. I would like to have some fields use default values, supplied via Client's Details, such as:

 

$emailaddress = $params['customfields']['Email Address'];
if (!$emailaddress) $emailaddress = $params['clientsdetails']['email']);

 

However, I think it would be nice for the user to see that these fields could be left blank, and if so, they would be populated with the user's information. This could be done via the "Description" in the Product setup > Custom Fields I suppose, but maybe there's a better way.

 

All this works fine except these default values don't get updated in the table tblcustomfieldsvalues. To do this, a simple update_query seems to be in order, such as:

 

update_query("tblcustomfieldsvalues",array("value"=>$emailaddress),array("fieldid"=>XX,"relid"=>$params['serviceid']));

 

However, this assumes fieldid is known. This will value will be different in each WHMCS database using this module. How would I compose the update query to update a range of custom field values at once?

I also need an answer to this question.
