Redirect to page after true result

Hello thanks for your time. I have a file called get getresult.php it checks for username and password on mysql server for users that login.

I j开发者_如何学编程ust it to redirect to a page index.php if login is successful. Thanks for any help the can be provided.

<?php
// version 1.1
if (isset($_POST['password'])) // if the password is set then the  form has been submitted on login.php page
{
 include("config.php");
 $username =  mysql_real_escape_string($_POST['username']);
 $password = mysql_real_escape_string($_POST['password']);
 $qstr = "SELECT * from members where username ='$username' and password ='$password'";

 $result = mysql_query($qstr);
 if (mysql_num_rows($result)) echo "<font color=#008000><Center><b>**Successful Login**</b></Center></font>" 
 **//// I thought maybe this would be the section for the redirection code****
;

else echo "<font color=#ff0000><Center><b>**Failed Login**</b></Center></font>";
 mysql_close();
}
else echo "<font color=#ff8000><Center><b>**No login attempted**</b></Center></font>";

?>

after the check of login do this:

header("Location: newPage.php"); // replace newpage with whatever you want

UPDATE

put the header BEFORE any echoing:

header("Location: newPage.php"); // replace newpage with whatever you want
if (mysql_num_rows($result)) echo "<font color=#008000><Center><b>**Successful Login**</b></Center></font>"

You have to make sure that you don't echo or print anything before, and then you can do:

header("Location: http://www.yoursite.com");

Alternatively, if you want to redirect after having printed stuff, I usually have a function that prints javascript

function refresh_to( $location = 'index.php'){
    $output = '<script> window.location.href = '.$location.'; </script>';
    return $output;
}

And call it out afterwards.

header("Location: /my/new/location");

header("refresh:5;url=http://google.com");
// version 1.1
if ( isset($_POST['password']) ) { // if the password is set then the form has been submitted on login.php page
    include("config.php");
    $username =  mysql_real_escape_string($_POST['username']);
    $password = mysql_real_escape_string($_POST['password']);
    $qstr = "SELECT * from members where username ='$username' and password ='$password'";

    $result = mysql_query($qstr);
    if (mysql_num_rows($result)) {
        $return = "<font color=#008000><Center><b>**Successful Login**</b></Center></font>";
    } else {
        $return = "<font color=#ff0000><Center><b>**Failed Login**</b></Center></font>";
    }
    mysql_close();
} else {
    $return "<font color=#ff8000><Center><b>**No login attempted**</b></Center></font>";
}

// Do the output    
print($return);

Remember separate Logic and Output, this will be good practice for your coding.

Notice i use header and then do print, also in the header i put refresh 5 (seconds), this will give time for your visitor to read the notice you give (what the point, if you give notice but they didn't have time to read it.)
