Calling a function from a link

[romio]

This is my menu code on my index.php:
[code]
function menu_case($selected)
{
    switch($selected)
    {
        case 0:
            echo add_product_form();
            break;
        case 1:
            echo find_products();
            break;
        default:
            echo find_products();
            break;
    }
}
[/code]
When the page loads I have find_products() as a default value, on the same page I have a "Add Product" which will link to a function, how can I do that?

I have tried doing this but I get an error:

[code]
<a href='<? menu_case(0) ?>' class='style10'>Add Product</a> | Add  Category<br><HR></td>
[/code]

Note that my add_product_form() contains a form which be displayed on the same page.

i think you should return the value from that function:

function menu_case($selected)
{
switch($selected)
{
case 0:
$someVar = add_product_form();
}

return $someVar;
}

Php runs on the server so cant be directly called from links (like javascript), but there are ways....

An example...
[code]
<?php

  if (isset($_GET['action'])) {
    switch ($_GET['action']) {
      case "foo":
        foo();
      break;
      case "bar";
        bar();
      break;
    }
  }

  function foo() {
    echo "this is foo\n";
  }

  function bar() {
    echo "this is bar\n";
  }

?>

<a href="?action=foo">call foo</a>
<a href="?action=bar">call bar</a>
[/code]
Hope this helps.
