I have it exactly the way he does but it wont echo anything or work at all. The login page worked great in his tutorial. What do I have wrong? I cant figure it out. Please help! echo "<h1>Register</h1>"; $submit = $_POST['submit']; $fullname = strip_tags($_POST['name']); $username = strip_tags($_POST['user']); $password = strip_tags($_POST['password']); $verifypassword = strip_tags($_POST['verifypassword']); $date = date("Y-m-d"); if ($submit) { if($fullname&&$username&&$password&&$verifypassword) { password = md5($password); verifypassword= = md5($verifypassword); } else echo "Please fill in all fields!"; } Code: [Select] <html> <form action='register.php' method='POST'> <table> <tr> <td>Full Name:</td> <td><input type='text' name='name'></td> </tr> <tr> <td>Username:</td> <td><input type='text' name='user'></td> </tr> <tr> <td>Password:</td> <td><input type='password' name='password'></td> </tr> <tr> <td>Verify Password:</td> <td><input type='password' name='verifypassword'></td> </tr> </table> <p><input type='submit' name='submit' value='Submit'></p> </form> </html> ok..ive done this a million times..i have a working example here and i copied it and amended it for this new project but for some reason i cant get a form to post data to another page. this is the error message i get Notice: Undefined index: username in C:\wamp\www\uni\fyp\site\mobile\login.php on line 16 Notice: Undefined index: password in C:\wamp\www\uni\fyp\site\mobile\login.php on line 17 here is my form code: <form method="post" action="login.php"> <table align="center" cellpadding="0" cellspacing="0"> <tr> <td style="vertical-align:top;">Username: </td><td><input type="text" name="username" value="" /></td> </tr> <tr> <td style="vertical-align:top;">Password: </td><td><input type="password" name="password" value="" /><br /><input type="submit" id="submit" value="Login" /></td> </tr> </table> </form> and here is the code within the login.php where the form should post to $username = $_POST['username']; $password = $_POST['password']; // Help protect against MySQL injection $username = stripslashes($username); $password = stripslashes($password); $username = mysql_real_escape_string($username); $password = mysql_real_escape_string($password); // Selecting data from database where correct username and password are found $sql="SELECT * FROM customer WHERE username='$username' and password='$password'"; $result=mysql_query($sql) or die(mysql_error()); i cant see anything wrong..been looking for hours...please please help me well, i have a hosting site and i enter via cpanel,(just in case it matters) and i am trying to use the mai() function but it won't work.. :S this is my code Code: [Select] <?php $to = "pato.llaguno@gmail.com"; $subject = "Hi!"; $body = "Hi,\n\nHow are you?"; if (mail($to, $subject, $body)) { echo("<p>Message successfully sent!</p>"); } else { echo("<p>Message delivery failed...</p>"); } ?> the output is Message successfully sent! but i don't get any mail in the adress specified :S Test code test.php Code: [Select] <script type="text/javascript"> $(document).ready(function(){ $("#sub").click(function(){ $("#test").load("sub.php"); $.get("sub.php", { uid: $("#sub").attr('uid') }); }); }); </script> <a href="#" id="sub" uid="1">Sub</a> <div id="test"> </div> sub.php Code: [Select] <?php $id = $_GET['uid']; echo $id; ?> I am trying to load a file after clicking the href which has an extra attribute so i can query the database with it, however the get method seems to be not working, it works on other pages though.
