[SOLVED] $_POST is different from $_REQUEST

Xeoncross · October 1, 2007

Has anyone ever had a PHP script that had different values in the $_POST array than in the $_REQUEST array?

Take a look at the values below and you will see that data sent through a method="POST" form became different for both arrays.

print_r($_POST); - inputs became a string

Array
(
    [inputs] => Array
    [action] => disable
    [submit] => submit
    [active] => 1
)

print_r($_REQUEST); inputs became an array

Array
(
    [active] => 1
    [inputs] => Array
        (
            [0] => 65
            [1] => 64
        )

    [action] => disable
    [submit] => submit
)

because they ARE different. compare GET too...

It is because $_REQUEST holds the values for both GET and POST.

I know they are different - but not whole array-to-string different. What is going on? why would a POST array be a string? (REQUEST got it right).

I didn't know that. Thank you!

$_REQUEST and $_POST the same here!

Array
(
    [txtbox] => foo
    [inputs] => Array
        (
            [0] => b
            [1] => c
        )

    [submit] => submit
)

Array
(
    [txtbox] => foo
    [inputs] => Array
        (
            [0] => b
            [1] => c
        )

    [submit] => submit

Not sure what you mean?

Test code:

<?php


echo '<h1>$_REQUEST</h1>
<pre>' . print_r($_REQUEST, true) . '</pre>

<h1>$_POST</h1>
<pre>' . print_r($_POST, true) . '</pre>';

?>
<form action="#" method="post">
  Text: <input type="text" name="txtbox" /><br />
  Inputs:<br />
  <input type="checkbox" name="inputs[]" value="a" /> A<br />
  <input type="checkbox" name="inputs[]" value="b" /> B<br />
  <input type="checkbox" name="inputs[]" value="c" /> C<br />
  Submit: <input type="submit" name="submit" value="submit" />
</form>

wildteen88 - If you changed your form method to GET they wouldn't end up the same.

same output no change. Tested in FF, IE 7 and Safari (Win). I cannot see how $_POST displays differently.

Okay, manually put something in the URL. Just add this

?id=1

Then submit the form.

That makes them different, I just tested it.

Ok, I just striped my code down to something simple like the below code - and it works.

So my guess is that somewhere in my system something is messing with the $_POST data and turning it into a string. (the only thing is that I can't find anywhere where my code messes with the $_POST data!)

So any ideas?

        </dl>
    </fieldset>
</form>

Again, the simplified code above works just fine.

Ok, I found it.

I was cleaning the POST data somewhere like this:

<?php
if (get_magic_quotes_gpc()) {
    //foreach $_GET variable
    foreach($_GET as $key => $value) {
        //Clean the value of the added slashes
        $_GET[$key] = stripslashes($value);
    }
    //foreach $_POST variable
    foreach($_POST as $key => $value) {
     
        //Clean the value of the added slashes
        $_POST[$key] = stripslashes($value);
    }
}
?>

Which is bad because I had a multi-level $_POST array ($_POST['inputs'][0] was on level 3). So I was messing myself up by trying to clean the forward slashes from the posted code. aghhhhh!
