<p>The <code>$courseDatas</code> variable needs to be defined outside of your while loop as an array.</p> <p>EDITED - HERE IS WHAT YOUR SCRIPT NEEDS TO LOOK LIKE:</p> <pre><code>$coursequery = "SELECT CourseId, CourseNo, CourseName, Duration FROM Course ORDER BY CourseNo"; $courseqrystmt=$mysqli->prepare($coursequery); // You only need to call bind_param once $courseqrystmt->execute(); $courseqrystmt->bind_result($dbCourseId,$dbCourseNo,$dbCourseName,$dbDuration); $courseqrystmt->store_result(); $coursenum = $courseqrystmt->num_rows(); $courseHTML = ''; $courseHTML = '<select name="courses" id="coursesDrop">'.PHP_EOL; $courseHTML .= '<option value="">Please Select</option>'.PHP_EOL; $courseDatas = array(); while ( $courseqrystmt->fetch() ) { $courseHTML .= sprintf("<option value='%s'>%s - %s</option>",$dbCourseId,$dbCourseNo,$dbCourseName) .

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
