Adding another view - Department Course Listings

Create another PHP file that displays course information based upon a department_code parameter.

Need to link to to courses.php:

Modify the department listing to include the hyperlink:

<!DOCTYPE html>
<html>
 <head>
  <title>Departments</title>
  <link rel="stylesheet" href="site.css" type="text/css"/>
 </head>
 <body>
<h1>Faculty of Arts &amp; Sciences</h1>
<h2>Departments</h2>
<?php
// Connecting, selecting database
  $mysqli = new mysqli('localhost','class','cscie12','coursecatalog');
  if ($mysqli->connect_errno) {
      echo "Failed to connect to mysql: ".$mysqli->connect_errno." ".$mysqli->connect_error;
  }

// Performing SQL query
$query = 'SELECT distinct department_short, department_code FROM courses order by department_short';
$result = $mysqli->query($query);

// Printing results in HTML
echo "<ul>\n";
while ($row = $result->fetch_assoc()) {
  echo "<li>";
  echo "<a href=\"courses.php?department_code=$row[department_code]\">$row[department_short]</a>";
  echo "</li>\n";
}
echo "</ul>\n";

// Free resultset
$result->free();
// Close connection
$mysqli->close();

?>

</body>
