Time is Money (part 1) - Time For Bed (
Page 9 of 9 )
Of the five options available
on the main menu, I've just taken care of two - or, if you want to get technical
about it, 40% of the project is now complete. I'll do one more, just to put me
on the right side of the halfway mark, and then shut shop for the
day.
Since I'm asleep on my feet, I think I'll skip the data entry and
report generation code for the moment - this is bound to be complex, and I need
all my wits about me to tackle them. Instead, I think I'll handle the last item
on the menu next - the "logout.php" script.
<?
// logout.php - destroy user session
// destroy session data
session_start();
session_destroy();
// redirect to index page
header("Location:index.html");
?>
I don't even think this qualifies to be called a script -
it's just three lines of code. All it does is destroy the current session and
redirect the browser back to the index page to await a new login.
And
that's about it for the moment. We've accomplished a fair amount of work so far
- we've got the requirements down, designed a database schema, put together
scripts to handle user login and logout, and written all code necessary to
display project and task information.
In the concluding part of this
article, I will be discussing the scripts which handle timesheet display, record
addition and deletion, and report generation. These scripts, especially the ones
that handle report generation, will be substantially more complex than the ones
you've just seen, so I need to give them some thought before sitting down to
write the code. Why don't you do the same, and we'll get together soon to
compare notes?
Note: All examples in this article have been tested on
Linux/i586 with Apache 1.3.12, mySQL 3.23 and PHP 4.06. Examples are
illustrative only, and are not meant for a production environment. YMMV!
