I want to remove the First Name and Last Name fields from this page. So, I can run a str_replace() to remove the lines.

In this case, I have $search and $replace … but I need $subject [Ref – http://php.net/manual/en/function.str-replace.php]

How to get the $subject ?

OR, anybody know any other way to do this?

  1. you could use the output buffer, to construct your page?

    ob_start();
require_once(ABSPATH. 'wp-admin/profile.php');
$subject = ob_get_clean();

    and then do a search and replace against that?

    hope this helps 🙂
