frank_solo Posted May 13, 2011 Share Posted May 13, 2011 Ok so I'm still having problems. This is what I need: I want a function to echo a message if a username does not pass my requirments. - Only letters and / or numbers - Must start with a letter (not a number) - No spaces The current code is not working for me. Please help }else if (!(eregi('/[A-Za-z0-9-]+',($_POST["username"])))){ echo "<p> </p><p> </p><p> </p><br />Must only contain numbers and letters and cannot exceed 10 characters.<p> </p><p> </p><a href='javascript:javascript:history.go(-1)'>Click here to go back to previous page</a>"; Quote Link to comment Share on other sites More sharing options...
