In the first part of this tutorial, we looked at how PHP can be used to display dynamic data, like todays date. You’ve also by now hopefully figured out the process of making a .php file, uploading it to your web host, and running it. With that much done, its time to try something a little more adventurous!
For this, you need to create two .php files - the first one should contain the following and be called “part2a.php”:
<html>
<body>
<form action="part2b.php" method="post">
<input type="text" name="myname" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
And the second file should contain the following, and be called “part2b.php”:
<?php
echo "You entered this on the previous page: ".$_POST['myname'];
?>
And your done! Upload both files to the same directory on your webhost, and then go to yourwebhost.com/part2a.php.
So what is happening here? Well, the first page is taking in some data from the user into a form. When the user then clicks submit, this data is the POSTed to a nominated new page, into which code is placed to deal with this incoming data. This is simple example of passing data, but if you can understand this, you’ve pretty much understood all you need to know to make more advanced things happen!
