WebWork Unit 5: php

Leave a comment

php intro course

This weeks project is to build a selector to select one of your classmates by name and display a link to their webpage.

first we’ll learn about php variables and arrays;

Next we’ll learn about php forms (you can also use forms in html but it’s simpler to build the form completely in php.

Step 1: create a file named ‘friends.php’.

Step 2: create a form handler file named ‘friendfinder.php’.

Step 3: Build a form method in friends.php. The code looks like this;

<!DOCTYPE HTML>
<html>
<body>

<form action=”friendfinder.php” method=”post”>
Name: <input type=”text” name=”name”><br>

<input type=”submit”>
</form>

Make up silly but NICE names for your classmates like; Sleepy, Goofy, Sneezy, etc.

Note: there’s no php in this file at this point but we’ll put some in later.
</body>
</html>

Step 4: Now build an array in friendfinder.php
