PHP simple mysql login - can't find the problem

I"m trying to do a quick setup test for html5/php/ajax/mysql combo (learning)

i've got my basic db with username and password as uni / uni
my html form
 
My form:

<form id="contactForm" action="doLogin.php" method="post">

  <h2>Login</h2>

  <ul>

    <li>
      <label for="userName">Your Username</label>
      <input type="text" name="userName" id="userName" placeholder="Enter Username" required="required" maxlength="40" />
    </li>
    <li>
      <label for="pWord">Your Password</label>
      <input type="password" id="pWord" placeholder="Enter Password" required="required" maxlength="40" />
    </li>

  </ul>

  <div id="formButtons">
    <input type="submit" id="submitForm" name="submitForm" value="Submit" />
    <input type="button" id="cancel" name="cancel" value="Cancel" />
  </div>

</form>

Open in new window

 
my doLogin.php

$unsafe_pw = $_POST['pWord'];
$safe_pw = mysql_real_escape_string($unsafe_pw);
$unsafe_un = $_POST['userName'];
$safe_un = mysql_real_escape_string($unsafe_un);

$sql="SELECT * FROM $tbl_name WHERE username='$safe_un' and password='$safe_pw'";
$result=mysql_query($sql);

$count=mysql_num_rows($result);

here's the problem, this always returns a count of 0 - however if i hardcode the password i.e.


$sql="SELECT * FROM $tbl_name WHERE username='$safe_un' and password='uni'";
then it's fine.
so the db connection is fine.
I can't see what the problem is.
if i do an echo $unsafe_pw - i'm getting nothing  - so that's failing somewhere in the post.

Try replacing line no 15 to

<input type="password" name="pWord" id="pWord" placeholder="Enter Password" required="required" maxlength="40" />

Check out $_POST['userName'], unless there is no input tag with NAME 'userName', you get no such $_POST variable.

Bye, Olaf.
