Help with an AJAX function

[Joe Blow]

I have someone helping me out with a minor modification on my vB 4.2.1 forum who is having trouble with an AJAX function.

A custom checkbox userfield needs to be updated. Here is the line for the AJAX request:

var postData = {"do" : "saveuserfield", "fieldid" : "5", "securitytoken" : SECURITYTOKEN, "userfield" : {"value" : cValue}};

How do you set the userfield array for this request, since there is no documentation for it? The function that is being called is saveuserfield and is located in ajax.php

Any ideas?

Any help appreciated!

Here's some code from clientscript/vbulletin_profilefield_edit.js:

var A = new vB_Hidden_Form(null);
A.add_variables_from_object(this.element);
YAHOO.util.Connect.asyncRequest("POST", fetch_ajax_url("ajax.php"), {success: this.post_save, failure: this.request_timeout, timeout: vB_Default_Timeout, scope: this}, SESSIONURL + "securitytoken=" + SECURITYTOKEN + "&do=saveuserfield&fieldid=" + this.fieldid + "&" + A.build_query_string())



this.element is the form object that has the fields for the profilefield being edited. You can also just call the vB_Hidden_Form function add_variable() for each variable to be added, if there's no form object. The code for vB_Hidden_Form is in clientscript/vbulletin-core.js.
