How to call a JavaScript function from PHP?

I have a php page in which I echo certain things depending on the user privilege (admin or user). I would like to know if I can call a javascript function when a button is clicked.

<?php
if ($_SESSION['access_rights']=='admin') {
     $id = $_GET['id'];
     $userName = $_GET['username'];
     echo "<a href='../view/confirmDelete.php?id=$id&type=task&username=$userName'><input type='button' class='delete-btn' value=''/></a>
           <a href='../view/editTask.php?id=$id&username=$userName'><input type='submit' class='edit-btn' value=''/></a>";
}
?>

The function I would like to call is as follows. This is placed in the head of the page.

<script type="text/javascript">
function deleteTask(id,task,name) {
    var conBox = confirm("Are you sure you wanna delete task assigned to "+ name + " ?");
    if (conBox) {
        location.href="<?=$_SERVER['PHP_SELF'];?>"
    } else {
        return;
    }
}
</script>

I was wondering if the function 'deleteTask()' can be called via a href like 

<a href="javascript" deleteTask('<?=id;?>','task','<?=userName?>');">Delete me</a>

else using onclick="deleteTask();

I am required to pass arguments to the function. I am unable to the javascript call in href as it requires quote. Any ideas?

With the quotes directly after javascript you close the href-attribute. Use a : to seperate the keyword javascript and the command:

In PHP (don't forget to escape the quotes):

echo "<a href=\"javascript:deleteTask('$id;','task','$userName');\">Delete me</a>";

or HTML:

<a href="javascript:deleteTask('<?=$id?>','task','<?=$userName?>');">Delete me</a>

  • No it wont work as I'm echoing the 'a href'. So the quotes are a problem – Shyam K Feb 07 '12 at 07:31

    The answer is echo " "; and change the script accordingly. – Shyam K Feb 07 '12 at 08:53

Try this

echo "<input type='button' value='Click Here' onclick='deleteTask(id, task, name)' />"
