HELP: $_post on server, but not locally!?

leatherback

Hi All,

I am building a site with forms etcetc. I use post to submit the form to a PhP page, which processes the input. Not a problem.

I got everything working, uplodaded it to the server of the provider.. Nothing works!

That part I figured it out: the variables don't get passed into the PhP page. So I changed the variables used to $post['var'] and now the page works on the server. But not on my local server! Now the variables are not recognized on my local server!

Is there an easy solution for this? Maybe something like:

If (You need $post[''])
{
Then read all the vars
}
else
{nothing special}

Oh.. Yeah: Second question: Is there a way to get all the var's from a post, and getting the correct names for it too??

Now I use:

$username = $POST['username']
$pass = $POST['pass']
... Etc...

Which is really annoying when you have several large (>30 entries) forms to process.. How do you do this!

Thanks!

Turn register globals off in your PHP (not PhP) ini to match your server.

Hi Blob,

Thanks for your reply. Know I know it has to do with register globals on or off..

But the solution you suggest is not really an option: I am working on a few sites, hosted on a number of servers. So I'd prefer to not change my server settings (Because I'd then have to change all the pages..). The providers'settings are not open for me.

Therefor I'd prefer to write a small include which I add to each form-processing page, which will check for register globals on or off, and automatically extract all the variables.

Any other ideas??

Thanks,

just assume that register_globals is off.
even if it is on, you still can access $_POST, $GET etc after all.

Hi Laserlight,

Read my first post: I cannot acces $_post! I do not get my variables passed on my local servers...

laserlight

I read that, but I had the wrong impression as you used $post and $post and then $POST

btw, what is the version of PHP you are using?
Because whether register_globals is on or off you can access $_POST
unless...
you are using a version of PHP which requires $HTTP_POST_VARS

Hi Laserlight,

I am running PhP 4.0.6, Jun 22 2001

That too old to use $_POST ??

You have any idea for my other question: How to extract all the vars in the$_POST array in one big sweep?

Thanks!

leatherback

OK.

Getting there. HTTP_POST_VARS works. Using ech() I can get all the variables from the array.

THanks!

You don't always have to declare the POST vars - more efficient if you don't.

However, if you need to:

extract($_POST, EXTR_PREFIX_ALL, "prefix");

Most of the time you'll want to process POST vars for security and other reasons so I often use this:

foreach ($POST as $key => $value) {
${'prefix' . $key} = htmlspecialchars(addslashes(trim($value)));
}

Note that var names are prefixed with a string in each method: the prefixes are important. A forged from could overwrite previously declared vars in your script in the same scope as the extract / foreach lines and which have the same name as a forged POST var.
