You will then be prompted to type in your password.

With the database set up, let’s go on and implement the basic site.

Implementing the Basic Site

The first page we’ll build will be called login.php because it provides users with the opportu-

nity to log in to the system. The code for this first page is shown in Listing 24.2.

LISTING 24.2 ogin.php—Front Page of the PHPBookmark System

require_once(“bookmark_fns.php”);

do_html_header(“”);

display_site_info();

display_login_form();

do_html_footer();

This code looks very simple, as it is mostly calling functions from the function API that we

will construct for this application. We’ll look at the details of these functions in a minute. Just

looking at this file, we can see that we are including a file (containing the functions) and then

calling some functions to render an HTML header, display some content, and render an HTML

footer.

The output from this script is shown in Figure 24.3.

The functions for the system are all included in the file bookmark_fns.php, shown in Listing

24.3.

LISTING 24.3 bookmark_fns.php—Include File of Functions for the Bookmark Application

// We can include this file in all our files

// this way, every file will contain all our functions

require_once(“data_valid_fns.php”);

require_once(“db_fns.php”);

require_once(“user_auth_fns.php”);

require_once(“output_fns.php”);

require_once(“url_fns.php”);
