passing variables in query string

Question

$courses_taken=$row['course_id'];
<a href="course.php?course_id=$courses_taken"></a>

As you can see from above code, i'm taking a variable and passing it in query string, but this method is wrong.

How can i pass a variable in query string, as each user will have opted for different courses, thus they will have different course_id.

Is there a way to do it?

You need an echo statement, and then interpolate the variable inside the string.

$courses_taken = $row['course_id'];
echo "<a href='course.php?course_id=$courses_taken'>click here</a>";

I'm sure this works, but another answers is more suitable for me.

Try this:

You are not using php tag to pass php variable in your anchor tag.

Do it like this:

<a href="course.php?course_id=<?= $courses_taken; ?>"></a>

- Thanks

He's using the "short open tags" feature. <?= is short for <?php echo

Yes use either of method. Both are ok with this.
