I am writing a page that a user would be able to view their password in plain text (actually, this is for the site administrator), instead of in the MD5 encryption.  I am able to CREATE the password and encrypt it, but in this field, (and the subsequent query) I want it viewable.
if (isset($_POST['Submit'])){
 

//$year = $_POST['idx'];
 
 

$idx = $_POST['idx'];	
 

    $pass = $_POST["password"];

    $password = md5($pass);

	

$username = $_POST['username'];

$validated = $_POST['validated'];

$firstname = $_POST['firstname'];

$lastname = $_POST['lastname'];

$address = $_POST['address'];

$city = $_POST['city'];

$state = $_POST['state'];

$zip = $_POST['zip'];

$phone = $_POST['phone'];

$email = $_POST['email'];

$billing = $_POST['billing'];
 
 

$username = mysql_real_escape_string($username);

$password = mysql_real_escape_string($password);

$validated = mysql_real_escape_string($validated);

$firstname = mysql_real_escape_string($firstname);

$lastname = mysql_real_escape_string($lastname);

$address = mysql_real_escape_string($address);

$city = mysql_real_escape_string($city);

$state = mysql_real_escape_string($state);

$zip = mysql_real_escape_string($zip);

$phone = mysql_real_escape_string($phone);

$email = mysql_real_escape_string($email);

$billing = mysql_real_escape_string($billing);
 
 
 

$update_user = "UPDATE `user` SET

         `username` = '$username',

         `password` = '$password',		 

         `validated` = '$validated',

         `firstname` = '$firstname',

	     `lastname` = '$lastname',

	     `address` = '$address',

		 `city` = '$city',

		 `state` = '$state',

		 `zip` = '$zip',

		 `phone` = '$phone',

		 `email` = '$email',

	     `billing` = '$billing' WHERE `idx` ='$idx'";

         echo "<br><br>";

		 
 
 

         mysql_query($update_user) or die("Problem with this query");
 
 

////////////////////////////HERE IS THE ACTUAL FORM/////////////
 

			echo "<tr bgcolor=\"#DCDCDC\" align=\"left\"><td><b>Username:</b></td> ";

			echo "<td><input name=\"username\" type=\"text\" value=\"".$row['username']."\"  size='25' maxlength='60'  /></td></tr>";

			

			echo "<tr bgcolor=\"#DCDCDC\" align=\"left\"><td><b>Password:</b></td> ";

			echo "<td><input name=\"password\" type=\"text\" value=\"".$row['password']."\"  size='25' maxlength='60'  /></td></tr>";
 

			echo "<tr bgcolor=\"#DCDCDC\" align=\"left\"><td><b>Validated:</b></td> ";

			echo "<td><input name=\"validated\" type=\"text\" value=\"".$row['validated']."\"  size='25' maxlength='60'  /></td></tr>";

MD5 is a one encryption method if you want to see it in plain text you will have to save it in plain text (or use another encryption method who is reversible).

MD5 is not an encryption algorithm, but a hash algorithm, which is NOT reversible. So, if you want to view the password in plain text, either store it in plain text, or use a symmetric encryption algorithm like 3DES, RC4 or AES.

Have a look at these tutorials:
