Autofill field

[JeffD]

I created a method that will autofill a field with the sum of 2 fields. How will I trigger the function inside the field and how will I pass the value of the 2 fields to the function? Here is the snippet of my code:

<class id="UserRequest">
<fields>
<field id="var1" xsi:type="AttributeInteger" _delta="define">
<sql>va1</sql>
<default_value>
<is_null_allowed>false</is_null_allowed>
</default_value></field>
<field id="var2" xsi:type="AttributeInteger" _delta="define">
<sql>var2</sql>
<default_value>
<is_null_allowed>false</is_null_allowed>
</default_value></field>
<field id="total" xsi:type="AttributeInteger" _delta="define">
<sql>total</sql>
<default_value>
<is_null_allowed>false</is_null_allowed>
</default_value></field>
</fields>
<methods>
<method id="SumNumber" _delta="define">
<static>false</static>
<access>public</access>

<![CDATA
public function SumNumber($v1, $v2)
{
$total = $v1 + $v2;
return $total;
}
]>
</ code>
</method>
</methods></class>

You'd need to hook in some methods. I would personally use AfterInsert() and AfterUpdate(); and then call the SumNumber() function.
