If not, the 1_3 and 1_6 will need to change.</p> <p>Also, you said "Robert R" but this will create "robert r" since you are using strtolower. </p> https://legacy.forums.gravityhelp.com/topic/username-of-first-name-and-first-letter-last-name#post-114275 Fri, 04 Jan 2013 22:48:42 +0000 RobertR 114275@https://legacy.forums.gravityhelp.com/ <p>Is it possible to assign a username to a new user using the First Name + 1st letter of the Surname? Like Robert R., I think I'm in the right direction using <a href="http://php.net/manual/en/function.substr.php" rel="nofollow">http://php.net/manual/en/function.substr.php</a><br /> but can't get it work. Any suggestions on this are welcome!</p> <pre><code>&lt;?php add_filter(&#39;gform_username&#39;, &#39;auto_username&#39;); function auto_username($username){ $username = strtolower(rgpost(&#39;input_1_3&#39;) . $string[0];(rgpost(&#39;input_1_4&#39;))); if(empty($username)) return $username; if(!function_exists(&#39;username_exists&#39;)) require_once(ABSPATH . WPINC . &quot;/registration.php&quot;); if(username_exists($username)){ $i = 2; while(username_exists($username . $i)){ $i++; } $username = $username . $i; }; return $username; } ?&gt;</code></pre>
