the Switch command

[thebaxter]

hey everyone,

i am trying to rewrite a lot of my code to work with the newest version of php and having register_globals off.

i have a script that uses the switch command, it looks like this

switch($action) {
case "update_password":
link_header();
update_password();
link_footer();
break;
case "password_form":
link_header();
navigation();
password_form();
link_footer();
break;
case "linkForm":
link_header();
navigation();
linkForm();
link_footer();
break;

i was trying to use $_GET['action'] to replace the $action variable insdie the switch command, but i ran across a problem where once you submit a form the switch command will not work.

does anyone happen to have any ideas on how to remedy this problem?

any help would be greatly appreciated!

cheers

is the form submitted with method=get, if so $GET['action'] should work, but if it is submitted with method=post, you have to use $POST['action']

[thebaxter]

the forms are submitted through method=post. the problem with using the switch($_POST['action']) is that the following:

<table align="" width="500" border="0" align="left" cellpadding="3" cellspacing="2">

<tr>
<td class="tr2">
<?
echo "<a href=\"$PHP_SELF\">front</a>";
?>
</td>
</tr>
<tr>
<td class="tr2">
<?
echo "<a href=\"$PHP_SELF?action=linkForm\">add a new link</a>";
?>
</td>
</tr>
<tr>
<td class="tr2">
<?
echo "<a href=\"$PHP_SELF?action=logout\">logout</a>";
?>
</td>
</tr>
</table>

wont work unless i write the switch command like this: switch($_GET['action']). then if i do that of course the forms wont work.

so i'm a bit stuck.

[stolzyboy]

just do a check beforehand

if ($GET['action'] == "")
{
$action = $GET['action'];
}
else
{
$action = $_POST['action'];
}

switch($action)

Or just use $_REQUEST['action'] which will have one or the other available.
