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?

Answer 1

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

Answer 2

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>";

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

Answer 3

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>

• Barmar: He's using the "short open tags" feature. <?= is short for <?php echo
• Anand Solanki: Yes use either of method. Both are ok with this.
