Need Help Posting Test Score To Database


MjM8082

Recommended Posts

In my app, the users will take a multiplication test with 10 problems... I'm not sure how I would post the grade that the user got to the database.

 

When the user finishes the test and hits score it should post their Name/Date & Time/ and Score to the database. I have the name and date & time working. Just not sure how I would approach the score.

 

This is my application... It is small and simple to run in browser.

	$sql = "INSERT INTO results (result_name, result_score, result_date_time) VALUES ('$result_name', 100, NOW());";


	$db->exec($sql);





	//print_r ($_POST);
	$time1 = $_POST['ts'];
	$time1_object = new DateTime($time1);
	$now = new DateTime();
	$time_span = $now->diff($time1_object);

	$minutes = $time_span->format('%i');
	$seconds = $time_span->format('%s');
	$seconds+= $minutes * 60;

	echo "It took $seconds seconds to complete the test<hr />";



	foreach ($_POST as $problem => $answer)
