I'm building a webpage that shows different countdown timers depending on the user's selection. How do I call the JavaScript function that has the countdown timer from inside the PHP code I need to know the user's selection?
The webpage shows Finnish upper-secondary school students the time left for their matriculation exam. There are 9 different test days every spring and fall depending on the subject.
I made a select menu with the id "subject" where the user can select the subject.
To make the timer I made empty p tags and gave it an id "chemistry-timer" that I then use in the JavaScript to call the function. (I used this tutorial from w3schools)
This is what I tried to get the "chemistry-timer" to show:
<?php
$subject1 = $_GET["subject"];
if ($subject1 == "Chemistry") {
echo "<p id="chemistry-timer"></p>";
?>
When I run it I get an error message saying "unexpected 'chemistry-timer', which is weird because when I call the function in HTML like so
<p id="chemistry-timer"></p>
it works fine.
