manalnor Posted May 20, 2011 Share Posted May 20, 2011 Hello friends, I've tried to search over the Internet but didn't found any tutorial how to do the following :- let say we have form with input username and input email just 2 field HTML Code <form> <table> <tr> <td>Username :</td> <td><input id="username" size="20" type="text" name="username"></td> </tr> <tr> <td>Email :</td> <td><input id="email" size="20" type="text" name="email"></td> </tr> </table> </form> As you can see no submit button cause we will only check out if username and/or email is not stored already, by using ajax My problem : i can only check out for username (1 field) but i can not check for 2 fields or more and i want to know how to apply it for 2 fields (username and email) Here is my idea for only one field (username) I'll add in the HTML code this <td><div id="status"></div></td> and will add this java code <SCRIPT type="text/javascript"> pic1 = new Image(16, 16); pic1.src = "loader.gif"; $(document).ready(function(){ $("#username").change(function() { var usr = $("#username").val(); if(usr.length >= 4) { $("#status").html('<img src="loader.gif" align="absmiddle"> Checking availability...'); $.ajax({ type: "POST", url: "check.php", data: "username="+ usr, success: function(msg){ $("#status").ajaxComplete(function(event, request, settings){ if(msg == 'OK') { $("#username").removeClass('object_error'); $("#username").addClass("object_ok"); $(this).html(' <img src="tick.gif" align="absmiddle">'); } else { $("#username").removeClass('object_ok'); $("#username").addClass("object_error"); $(this).html(msg); } }); } }); } else { $("#status").html('<font color="red">The username should have at least <strong>4</strong> characters.</font>'); $("#username").removeClass('object_ok'); $("#username").addClass("object_error"); } }); }); </SCRIPT> Explain : it will get the input of username and will send it to check.php Now check.php code (should have all usernames that will compare with it) <?php if(isSet($_POST['username'])) { $usernames = array('john','michael','terry', 'steve', 'donald'); $username = $_POST['username']; if(in_array($username, $usernames)) { echo '<font color="red">The username<STRONG>'.$username.'</STRONG> is already in use.</font>'; } else { echo 'OK'; } } ?> Now it is very clear , if will automatic check the username now my problem is how to apply it for also email Quote Link to comment Share on other sites More sharing options...
