     Replace the echo line with:

     echo "<button onclick='document.location=\"show_job.php?id=$id\">Job</button>";-

     By the way, storing the $id in $_SESSION won't work - there is only one $_SESSION per web session, and since you are listing different jobs, $_SESSION['id'] will contain the LAST $id.

   • Session in PHP and Mysql

     Instead of having a boolean value for logged in or out, determine a reasonable amount of time for the session to expire (e.g., 1 month) and then add that amount of time to a timestamp and store that in the database as session_expires or something. Then you can check if the user's session has expired whenever you do your login checks.

     Additionally, to manually expire the session (for instance if a user logs out) just set the session_expires field to a timestamp in the past.

     EDIT

     I didn't have access to a computer over the weekend, so I couldn't properly update my answer.

     If you need to see active users, one thing I've done in the past is to use a last_seen timestamp field that updates any time the user does anything on the site. Then, on your "users logged in" page, just query for something recent like "last seen in the past 15 minutes."

   • Session in PHP not working. Why?

     Top Answer

     Answered Feb 04, 2018 · 1 votes

     session is not saved because in if condition you are checking the variable submit instead of $_GET['submit'] and also you didn't specify name of submit button

     <input type="submit" name="submit" value="sign in"><?phpif(isset($_GET['submit'])) { $_SESSION["user"] = $_GET["user"]; $_SESSION["password"] = $_GET["password"];}?>

     error of undefined variable is due to $_SESSION['user'] & ['password '] is not set because $submit is NULL variable and also you missed to close square bracket in password

     You need to use form method to pass the input value. Change your code like this :

     <div id="login"><form method="post"><label for="user">User</label><input type="text" id="user" name="user" tabindex="1" autofocus><label for="password">Password</label><input type="password" id="password" name="password" tabindex="2"><input type="submit" name="submit" value="sign in"></form></div><br><?phpif(isset($_POST["submit"])) { $_SESSION["user"] = $_POST["user"]; $_SESSION["password"] = $_POST["password"];}?>

     It is probably because of you forgot to start session on your php file. Try adding

     session_start();-

     function on every page. Then only php will be able to store your session variables.

   • session_unset() vs session_destroy() in PHP

     There are two very similar PHP function session_destroy() & session_unset(). Both seem to delete all variables registered to a session but there is difference between them.

     session_destroy() function: It destroys all of the data associated with the current session. It does not unset any of the global variables associated with the session, or unset the session cookie.

     Syntax:

     bool session_destroy( void )

     session_unset() function: It deletes only the variables from session and session still exists. Only data is truncated.

     Syntax:

     bool session_unset( void )

     Example 1: This example saving the session by using session.php file.

     <?php   // Function to start session session_start();   // Display the session id echo session_id();   // Check the session name exists or not if( isset($_SESSION['name']) ) {     echo '<br>' . 'session is set.'; } else {     echo '<br>' . 'session is destroyed'; }   $_SESSION['name'] = 'GeeksForGeeks'; $_SESSION['email'] = 'GeeksForGeeks@email.com' ;   ?>

     Output:

     Before using session_unset() function: Before using the session function it displaying the name and email.

     <?php   // Function to start session session_start();    // Check the session name exists or not if( isset($_SESSION['name']) ) {     echo 'session is set.'; } else...
