phpstuff Posted January 7, 2014 Share Posted January 7, 2014 Having issues here... All the links show up on the page that should, but I get an error code/array printed to the page. If the "user_level" is an undefined index shouldn't it be an "index" in the table? It isn't.. Not sure the issue here. <!DOCTYPE HTML> <head> <meta http-equiv="content-type" content="text/html"; charset="utf-8" /> <title>Welcome to this Site!</title> <style type="text/css" media="screen">@import "includes/layout.css";</style> </head> <body> <div id="Header">User Registration</div> <div id="Content"> <!-- End of Header --><h1>Welcome!</h1><h1>stuff</h1> <p>Welcome to !</p> <p>related roles </p> <!-- START of Header --> </div><!-- Content --> <div id="Menu"> <a href="index.php" title="Home Page">Home</a><br /> <a href="logout.php" title="Logout">Logout</a><br /> <a href="change_password.php" title="Change Your Password">Change Password</a><br /> <div class="error">An error occurred in script '/Applications/MAMP/htdocs/PHP_MYSQL/includes/footer_ch18.html' on line 17:Undefined index: user_level<br /> Date/Time: 1-7-2014 01:38:45<br /> <pre>Array ( [_GET] => Array ( ) [_POST] => Array ( ) [_COOKIE] => Array ( [PHPSESSID] => 94e3d43c2a4b7370631f30dfed03bb6c ) [_FILES] => Array ( ) [page_title] => Welcome to this Site!

phpstuff Posted January 8, 2014 Author Share Posted January 8, 2014 Somebody.....help!!! Here is what is printed out within the menu, between buttons CHANGE PASSWORD and SOME PAGE. Again, I just don't know what it's reffering to. I looked up "undefined index" on stack overflow and it mentioned that the error can be caused by not using ISSET for the array/variable, but I'm assuming the code is correct in the book.

phpstuff Posted January 8, 2014 Author Share Posted January 8, 2014 Ok, so I took a chance and added ISSET to the footer file, and I think it worked! Can somebody explain why it now works and shows no errors? Is this errata or not? This version works - to make it work I added: if (isset($_SESSION['user_level'])) { } <!-- START of Header --> </div><!-- Content --> <div id="Menu"> <a href="index.php" title="Home Page">Home</a><br /> <?php # Script 18.2 - footer_ch18.html // This page completes the HTML template // Display links based upon the login status if (isset($_SESSION['user_id'])) { echo '<a href="logout.php" title="Logout">Logout</a><br /> <a href="change_password.php" title="Change Your Password">Change Password</a><br /> '; // Add links if the user is an ADMIN if (isset($_SESSION['user_level'])) { if ($_SESSION['user_level'] == 1) { echo '<a href="view_users.php" title="View All Users">View Users</a><br /> <a href="#">Some Admin Page</a><br /> '; } } } else { // Not logged in. echo '<a href="register.php" title="Register for the site">Register</a><br /> <a href="login.php" title="Login">Login</a><br /> <a href="forgot_password.php" title="Password Retrieval">Retrieve Password</a><br /> '; } ?> <a href="#">Some Page</a><br /> <a href="#">Another Page</a><br /> </div><!-- Menu --> </body> </html> <?php // Flush the buffered output. ob_end_flush(); ?> Link to comment Share on other sites More sharing options...
Larry Posted January 8, 2014 Share Posted January 8, 2014 I suspect the problem is that your login code is not setting $_SESSION['user_level']. Link to comment Share on other sites More sharing options...
phpstuff Posted January 10, 2014 Author Share Posted January 10, 2014 Thank you for your time in your response here Larry. I'll check this out - I'm sure I should have provided extra code but at the end of the book there are so many pages of code I just hoped that the error would prompt somebody familiar to point me in the right direction.
