Using GET Method to Maintain Variables After Logging In
- by John
Hello,
I am using a login system. When I navigate to comments/index.php without logging in, some variables get passed along using the GET method just fine. Then, if I log in while I am on this page, these variables disappear. The variables that disappear are $submission, $submissionid, and $url.
I thought I could use the GET method to keep them live after logging in by appending ?submission='.$submission.'&submissionid='.$submissionid.'&url='.$url.' to the URL of the login form action as seen below. But the variables still disappeared after I made this addition.
The relevant code I am trying to use is below.
Any idea what I can do to make it do what I want?
Thanks in advance,
John
In comments/index.php:
require_once "header.php";
include "login.php";
include "comments.php";
In login.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();
}
In comments.php:
$url = mysql_real_escape_string($_GET['url']);
echo '<div class="subcommenttitle"><a href="http://www.'.$url.'">'.$submission.'</a></div>';
$submission = mysql_real_escape_string($_GET['submission']);
$submissionid = mysql_real_escape_string($_GET['submissionid']);
The login function:
function show_loginform($disabled = false)
{
echo '<form name="login-form" id="login-form" method="post" action="./index.php?submission='.$submission.'&submissionid='.$submissionid.'&url='.$url.'">
<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/sandbox/register.php" title="Register">Register</a></div>
<div class="lostpasswordtext"><a href="http://www...com/sandbox/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>';
}
