Making a Login Work After Cache, Cookies, etc. Have Been Cleared
- by John
Hello,
I am using the code below for a user login. The first I try to login after cache / cookies, etc. have been cleared, the browser refreshes and the user name is not logged in. After that, logging in works fine.
Any idea how I can make it work the first time?
Thanks in advance,
John
index.php:
<?php
if($_SERVER['REQUEST_METHOD'] == "POST"){header('Location: http://www...com/.../index.php?username='.$username.'&password='.$password.'');}
require_once "header.php";
include "login.php";
require_once "footer.php";
?>
login.php:
<?php
if (!isLoggedIn())
{
if (isset($_POST['cmdlogin']))
{
if (checkLogin($_POST['username'], $_POST['password']))
{
show_userbox();
} else
{
echo "Incorrect Login information !";
show_loginform();
}
} else
{
show_loginform();
}
} else
{
show_userbox();
}
?>
show_loginform function:
function show_loginform($disabled = false)
{
echo '<form name="login-form" id="login-form" method="post" action="./index.php?'.$_SERVER['QUERY_STRING'].'">
<div class="usernameformtext"><label title="Username">Username: </label></div>
<div class="usernameformfield"><input tabindex="1" accesskey="u" name="username" type="text" maxlength="30" id="username" /></div>
<div class="passwordformtext"><label title="Password">Password: </label></div>
<div class="passwordformfield"><input tabindex="2" accesskey="p" name="password" type="password" maxlength="15" id="password" /></div>
<div class="registertext"><a href="http://www...com/.../register.php" title="Register">Register</a></div>
<div class="lostpasswordtext"><a href="http://www...com/.../lostpassword.php" title="Lost Password">Lost password?</a></div>
<p class="loginbutton"><input tabindex="3" accesskey="l" type="submit" name="cmdlogin" value="Login" ';
if ($disabled == true)
{
echo 'disabled="disabled"';
}
echo ' /></p></form>';
}
