Remove "Last Name" Field on Open Registration

What’s the best way to remove only the “Last Name” Field of the default form for Open Registration?

Thank-you for your inquiry.

When you say “the default form for Open Registration?”, are you referring to the registration form available at /wp-login.php?action=register, or s2Member’s Free Registration Forms?

Sorry for the confusion. I need to have the last name removed from the Registration process. I an using the PayPal Pro registration form.

I have copied the PayPal Pro form into my theme’s directory and will be modifying it there.

My client wants it to be the Landing page with the least amount of input:
First Name
E-Mail address
Choose a password

Thanks in advance for your support.

Thanks for the follow-up :-)

Removing the Last Name only (from a Pro Form template) will not work as expected. Even if you remove the Last Name field from display, server-side validation will fail, because the Last Name was not entered. I suppose you could fake a Last Name through a hidden input field though; if you don’t mind fake Last Names showing up in the Dashboard for each User. Maybe something like a period “.” would be easier to deal with.

You will need to edit your Custom Pro Form template.
