Guest Postmanpat Posted February 18, 2009 Share Posted February 18, 2009 Hello,I need some help, please!Until now I had a very goog working login.php script. But now I want to position it with 'div' and 'table' and it stops working (white page after login).Do I have to redirect the header? If so, how? Or what's the reason?Thank you. <?php session_start(); // Starts the session. ?> <html><head></head><body><div id="layer1" style="position: relative; width: 200px; height: 400px; z-index: 1"> <table style="width: 100%; margin-top: 150px; height: 100px"><tr><td> <?php include("conf.inc.php"); // Includes the db and form info. session_start(); // Starts the session. if ($_SESSION['name'] == '$name') { // User is already logged in. header("Location: homepage.php"); // Goes to main page. exit(); // Stops the rest of the script. } else { if (!isset($_POST['submit'])) { // The form has not been submitted. echo "<form action=\"login.php\" method=\"POST\">"; echo "<table>"; echo "<tr>"; echo "<td colspan=\"2\">Login:</td>"; echo "</tr>"; echo "<tr>"; echo "<td width=\"50%\">Lastname:</td><td width=\"50%\"><input name=\"name\" size=\"18\" type=\"text\" />"; echo "</tr>"; echo "<tr>"; echo "<td width=\"50%\">Password:</td><td width=\"50%\"><input name=\"password\" size=\"18\" type=\"text\" />"; echo "</tr>"; echo "<tr>"; echo "<td colspan=\"2\"><input type=\"submit\" name=\"submit\" value=\"submit\"</td>"; echo "</tr>"; echo "</table>"; echo "</form>"; } else { $name = form($_POST['name']); $password = md5($_POST['password']); // Encrypts the password. $q = mysql_query("SELECT * FROM `users` WHERE name = '$name' AND password = '$password'") or die (mysql_error()); // mySQL query $r = mysql_num_rows($q); // Checks to see if anything is in the db. if ($r == 1) { // There is something in the db. The name/password match up. $_SESSION['name'] = $name; // Sets the session. header("Location: homepage.php"); // Goes to main page. exit(); // Stops the rest of the script. } else { // Invalid name/password. exit("Incorrect name/password!<br /><a href=\"login.php\">Back to Login</a>"); // Stops the script with an error message. } } } mysql_close($db_connect); // Closes the connection. ?> </td></tr></table></div></body></html> Link to comment Share on other sites More sharing options...
justsomeguy Posted February 18, 2009 Share Posted February 18, 2009 You can't send headers after you send HTML code. The PHP code needs to go before the HTML code. Use variables in PHP to hold whatever information you want to add to the HTML, but the PHP code needs to go before the HTML if you're going to use headers (including session_start).
