Join David Powers for an in-depth discussion in this video Logging out selectively, part of PHP: Managing Persistent Sessions.
- In the previous video we logged out the user automatically…if the wrong username and password…were entered multiple times in the form, asking users…to confirm their identity.…However we also need a way for users to logout normally.…So let's see the code for that.…Each of the restricted pages, includes this file,…logout_button.php.…It contains an html form with a logout button…and on line three we create a session variable called…return_to, and set it's value to SERVER[ "PHP_SELF"]…in other words, the current URL.…
And this is in case the user of a persistent session…decides to cancel the logout process.…So we'll know where to return the user to…when they click cancel.…The forms action is set to logout.php…and the method is post.…logout.php is here.…And this contains a form with php blocks above the doc type…and also below the closing html tag.…Let's begin by looking at the form.…
The action is set to SERVER[ "PHP_SELF"]…in other words, the page will reload when one of…the submit buttons is clicked,…and it uses the post method.…
