error on Session_Start() – PHP



I am kind of new on PHP. I could not figure out what went wrong on my ph.

Here is code:

include 'dbc.php';
$user_email = mysql_real_escape_string($_POST['email']);
if ($_POST['Submit']=='Login')
$pass = $_POST['pwd'];
$sql = "SELECT id,user_email FROM rmusers WHERE
user_email = '$user_email' AND
user_pwd = '$pass' AND user_activated='1'";
$result = mysql_query($sql) or die (mysql_error());
$num = mysql_num_rows($result);
if ( $num != 0 ) {
// A matching row was found - the user is authenticated.
list($user_id, $user_email) = mysql_fetch_row($result);
// this sets variables in the session
$_SESSION['user']= $user_email;
if (isset($_GET['ret']) && !empty($_GET['ret']))
header("Location: $_GET[ret]");
} else
header("Location: myaccount.php");
//echo "Logged in...";
header("Location: myaccount.php");
header("Location: login.php?msg=Invalid Login");
echo "Error:";
<link href="styles.css" rel="stylesheet" type="text/css">
<?php if (isset($_GET['msg'])) { echo "<div class=\"msg\"> $_GET[msg] </div>"; } ?>
<p>&nbsp;</p><table width="40%" border="0" align="center" cellpadding="0" cellspacing="0">
<td bgcolor="#d5e8f9" class="mnuheader" >
<div align="center"><font size="5"><strong>Login
<td bgcolor="#e5ecf9" class="mnubody"><form name="form1" method="post" action="">
<p align="center">Your Email
<input name="email" type="text" id="email">
<p align="center"> Password:
<input name="pwd" type="password" id="pwd">
<p align="center">
<input type="submit" name="Submit" value="Login">
<p align="center"><a href="register.php">Register</a> | <a href="forgot.php">Forgot</a></p>

Hope you can tell me what did I do wrong.


Can you please let us know what error you receive?


Here are errors

have a look at dbc.php line 20, there must be some kind of output which causes the errors.


there is nothing on line 20

here is my code

//Database Information
$dbhost = "localhost";
$dbname = "xxxxxxx";
$dbuser = "xxxxxxxxx";
$dbpass = "xxxxxxxx";
// $link = mysql_connect("localhost","root","") or die("Couldn't make connection.");
$link = mysql_connect ($dbhost, $dbuser, $dbpass)or die("Could not connection. ");
$db = mysql_select_db($dbname, $link) or die("Couldn't select database");


I got it working now. There were space on line 20. Right now I have login page with two button for register and forgot. When we click on register or forgot it goes to another page. I did not want that. When click on forgot and I want email address box with subit box show up on same page. How do we do that? Like hide the address box and submit button till click on forgot then it will show up. Something like that. Can someone tell me the codes?


Glad you got it working.

That would be a job for JavaScript.
