How do we submit a form to SELF? I cann't think of it and thus was not even able to find it in the manual...

What's the syntax?

GreyBoy

for the form action, use ' $_SERVER[PHP_SELF] '

zzz

That's it! Perfect.

Just a question... if there a way to use some default for links, something like <a href="<? echo $HTTP_REFERRER ?> ">

Say I need to click a link to pass a variable and refresh a screen based on it.

GreyBoy

I think this is what you mean:

<?
       $var = $_GET['var'];

   if(isset($var))
   {
            header('Location: $var');
            exit;
    }

   <form method=POST action='$_SERVER[PHP_SELF]'>
  // form stuff
   </form>
?>

You could use an array to store your link locations in:

<?
        $links['link1'] = 'home.html';
        $links['link2'] = 'http://yoursite.com';
        // Etc...
?>

And your links would loke similar to:

This is great. But I think my problem is simplier than it appers. I'm building a tree-like menu.

Say I have level 1 links. When i click them I add var from level2 and display files associated with that level. I'd like to be able to use this file as an include on any page, without rewriting link values based on where the file is opened.

Is there something like:

<a href="<? SOME VALUE THAT WILL GRAB URL OF CURENT PAGE ?>?value1=1&Value2=2"

GreyBoy

Oh, so you just want the current page???

Then, your link would look like:

$_REQUEST['REQUEST_URI']&var=$var

But, if you want the page to just reload itself with the given values, I would just use $PHP_SELF

stolzyboy

well you have answered that yourself already

$_SERVER['PHP_SELF']

is the current page, for more information on server variables, go here

zzz

Yes!!!

...it's that time of a day when coffe doen't help any more...

GreyBoy

lol I just noticed your sig. I feel the same way about both my questions and my answers. I either try to expalin things too hard and they end up so complicated that even I cant understand them, or they are so short that they seem rude!!! :rolleyes:
