Adding another view - Department Course Listings

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

• courses.php - take a "department_code" parameter and produce alist of courses for that department.

Need to link to to courses.php:

• courses.php?department_code=CHEM
• courses.php?department_code=DGMD

Modify the department listing to include the hyperlink:

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