Topic awaiting preservation: _POST _GET (Page 1 of 1)

Hello,

When the global vars are off, one has to access post variables or get variables via either $_POST or $_GET in PHP.

how can I access the variable directly through one global array instead of checking first in $_POST then in $_GET ?

Seems like this might be what you are after:
[snip from manual]
Request variables: $_REQUEST
Note: Introduced in 4.1.0. There is no equivalent array in earlier versions.

An associative array consisting of the contents of $_GET, $_POST, and $_COOKIE.

Note: Prior to PHP 4.3.0, $_FILES information was also included into $_REQUEST.

This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. You don't need to do a global $_REQUEST; to access it within functions or methods.

If the register_globals directive is set, then these variables will also be made available in the global scope of the script; i.e., separate from the $_REQUEST array. For related information, see the security chapter titled Using Register Globals. These individual globals are not autoglobals.

Hello,

Yes DmS, then _REQUEST is what I was after.

Thanks

actually, I'd beat you if you used request in a project I was responsible for.

Actually,
"why can your variables come in either way? And why doesn't your code know which way it came", I'd ask you.
And then I'd probably beat you ;-)

Yeah wouldn't that leave you open to people hacking your POST variables using GET?

I've written admin code for a few sites that allow the admin to get to select entries to edit via and ahref link on one page, but also access that same admin page by filling in a form that feeds to the same script which makes some of the same variables come in either way... POST or GET depending on where they came from.

If there is an easier/better way to do this I would like to know so I can correct what I'm doing wrong.

Thanks

Butcher ... Look at Session Management using PHP ... you'll find chapters in every book with a title very much like that, and thats how you should be passing data around inside a single users session. The form can either post the data initially, or you can use some javascript to initialise the session variables directly from the form ...


Sessions use cookies, but there is also a way of circumventing the problem of browsers with cookies turned off. Look explanations of how to use the SESSID variable ... and here's a beaut ... HREF="nextpage.php?<?php echo strip_tags (SID)> ... does it for you.

see ... http://nl.php.net/session for more PHP manual info.
