传递href onclick变量以在PHP中运行

Question

I am trying to pass variables stored in href links to a function. Im able to define the variables from the query results. My problem is passing it to the function once the hyperlink is clicked. This is my code:

<?php
    foreach($pdo->query('SELECT * FROM sk_courses ORDER BY courseID') as $row)
    {
      echo "<a href='#' onclick='hrefClick(".$row['courseID'].");'/>".$row['courseID']."</a><br>";
    } 
?>

This is the function:

<script> 
function hrefClick($course){
      $newCourse=$course;
}
</script>

I was able to find a way to get it done? It seems pretty straightforward. This is what I came up with.

<?php
    foreach($pdo->query('SELECT * FROM sk_courses ORDER BY courseID') as $row){
      echo  "<form name='course".$row['courseID']."' action='index.php' method='GET'/>";
      echo "<a href='javascript: document.course".$row['courseID'].".submit();'/>".$row['courseID']."</a>";
      echo "<input type='hidden' name='courseID' value='".$row['courseID']."'/><br>";
      echo "</form>";
    } 
  ?>
