using functions instead of PHP_SELF

phpjaco

instead of using

<?php
if ($name != null) {
..........
}
?>

and onforms i have <action="<?php $PHP_SELF; ?>" i would rather like to use functions how do i go about using it?

do i say something like :
$list .= "<td><a href=\"<?php deleteStaff($id2); ?>\" ...
cause this doesnt work - looks for a page called "<?php deleteStaff($id2); ?>\

or do i use:
$list .= "<td><a href=\"#\" onClick=\"<?php deleteStaff($id2);?>\" ...
this also gives me a error, what should i do?

You haven't really got a lot of choice in the matter; you send a URL to the server, the server runs a script, and which bits of the script it runs depends on what the form fields' values are. (and you should be using $POST['name'] or $GET['name'], not $name).

Why do you want to do it differently?

it works fine for when i have form info for example then i can check if that variable is empty if not the script is run, but what if i have a value which is prefilled so for e.g in this case id2 is a variable sent from a previous page to the new page.

but if i say
if ($id2 != null) {
$sql = "delete from staff where id = $id2;
}
this will delete the user from the db! this is why i want to use a function for when a user presses "delete user" the function is called up and the user is deleted, but not sure how you call up a php function in a <a href="#"> tag.

Hi,

what about using a second get parameter, like

<a href="thescript.php?action=delete&id=$userid">Delete user</a>

In thescript.php:


$action = isset($_GET['action']) ? $_GET['action'] : 0;
$id = isset($_GET['id']) ? $_GET['id'] : 0;

if ($action == 'delete' && is_numeric($id) && $id>0) {
  // delete the user
}

This example just uses $GET and has to be modified a little bit to support both $GET and $_POST depending on how the form looks like.

PHP is a server side language so you can't use PHP code on the client side.
