Create a form in form builder to use as the registration form. The form should have 'Add to Contacts' ticked as its action so fields can be matched up with the attributes of the Contact node type.
You can place the registration form on the website with the <wt:form action="register"/> tag
Example:
<wt:if test="![wt:wt.request.fid]"> <wt:addButton type="General" source="Content" caption="Add a Content Block" noteditable="Date,Intro,Expires On,Expires,Force to Archive" /> <wt:list type="General" source="Content" template="Elements/General"/> </wt:if> <div id="form"> <wt:if test="[wt:wt.vars.wtFormError]"> <strong style="color: red">[wt:wt.vars.wtFormError]</strong> </wt:if> <wt:form source="Register As Member" action="register"/> </div>
If you would like the form to add the member to a certain Member Group, add a hidden field called 'Member Group' to the form and set its default value to the name of the member group.
