Hier Menus and PHP

[trooper]

Hi all

Just a quick question. Has anyone managed to successfully implement the heir menus with php?

I like the hier menus and want to pull the data from a database rather than hard code the array that is used.

cheers

Yep - just use php to output javascript for the menus arrays.

Ok i get it

But the question is how do i write the javascript without actually writing to the browser?

You have to "write to the browser". Remember anything you output to a page goes to the browser (unless its command line).

Eg:

<?php
echo "<script>function foo() { alert('bar'); }</script>";
?>

will output the javascript.

If you have problems dealing with " and ' (as javascript frequently uses both, and escaping can be a pain) use:

echo EOT<<<
<script>
function foo() {
alert("bar");
}
</script>
EOT;

You don't need to escape anything.

Just note that the EOT; must be located on a new line, with no tabs/spaces before it (in column 1) Enjoy.
