$_post

[cpradio]

I used the following code to get variable sent via a form but now I am wondering if I can get the variable names too so I can display it nicely in an email.

<?php
    if (isset($submit)) {
        foreach($_POST as $i) {
            print "$i<br>";
        }
    }
?>

Wont that display the value of each? Or is that what you're trying to accomplish?

[The Hobo]

Nevermind, you already knew that...

[cpradio]

Here is a test script of what information that code gets, I want to get the name="" attribute too and not just the value=""

Try this:

<?php
if (isset ($submit)) {
    while (list ($name, $value) = each ($_POST)) {
        echo "$name == $value<br>\n";
    }
}
?>

[cpradio]

that didnt work

[The Hobo]

This works for me:

<?php
    if ($action == 'show') {
        while (list ($name, $value) = each ($_POST)) {
            echo "$name == $value<br>\n";
        }
    } else {
        echo '<form action="work.php" method="post">
        <input type="hidden" name="action" value="show">
        <input type="text" name="fun"><br>
        <input type="submit">
        </form>';
    }
?>

[The Hobo]

you can see it here: http://www.vbshelf.com/work.php

[cpradio]

ahh, it works. I had placed your code beneath mine and it wouldn't run b/c the pointer was at the end of $_Post

[The Hobo]

So everything is good?

[cpradio]

yep, now i have a universal contact form/anything you want form

[scoutt]

FYI

if (isset($_POST["submit"])) {

if globals are turned off then submit will not get noticed. submit is just like any other variable from a form.

[The Hobo]

Same thing for ACTION, Hobo.

if ($_POST['action'] == 'show') { 

OKAY?

In later versions will globals be turned off automatically?

Hobo: I dont plan on using action as its just a worthless slot for me. I just plan on using that code to create Emails on the fly from any form.

Yes, starting in 4.2, it will be turned off by default.

Matt:That post was directed at myself. Not you.

[cpradio]

oh okay

Will the option to turn them on still be existant or is it forcing them to be off?

[scoutt]

you can still turn them on, but it is not recommended for security and speed issues.

[The Hobo]

I've grown to love the superglobals anyways

[cpradio]

damn, i now have to rewrite about 40 pages of code

[cpradio]

wait maybe not, is there any way to force globals on at runtime?

[scoutt]

yes you can set the globals on at runtime,

ini_set("register_globals", 1);

that iwll set it to 1, which is on. 0 is off.

[The Hobo]

You could mimic it by using the code I gave you below:

<?php
    while (list ($name, $value) = each ($_POST)) {
        //something
    }
?>

Okay, I can't remember how to do it. I'll get back to you.

[cpradio]

Well, the reason I asked is with ini_set("register_globals",1); I can now go back to my old php scripts add that line and not worry about them not working in 4.2

[scoutt]

I would test it first on a couple of pages first before your whole site. I tried a couple of other things like that and I remember having issues since the master setting was the other way.

[cpradio]

im almost positive my hosting service will have them on as its more convinent, so im not too worried.

but when the switch occurs I will test it locally first.
