$http_post_vars

yacoubisaac

I am trying to retrieve http_post_vars that should be passed to the next page. here is the code but when I print the variable out I get nothing? Thanks for the help.... Jake

page 1:
<form name="sf" method="POST" >
<INPUT TYPE="HIDDEN" NAME="ycat" value="aaa" >
<INPUT TYPE="HIDDEN" NAME="ycount" value="-1" >
<INPUT TYPE="HIDDEN" NAME="ysubcat" value="bbb" >.....

</form>

page 2:

<?php
include('itemBean.php');
include('ImageBean.php');
$ctr = $HTTP_POST_VARS["ycount"];
echo $ctr;
$imageBean = new ImageBean;
$stuff = $imageBean->m_image();
$value = $stuff[$ctr];
$i = $value->itemList;
?>

Could be you need to use single quotes in the variable name.

$HTTP_POST_VARS['myvar'];

Thanks but that didn't do anything.

you might need this:

while (list($key, $value) = each($HTTP_POST_VARS)) { 
$$key = $value; 

echo $ycount;
}

This may or may not help, but $HTTP_POST_VARS is depreciated. Get the variables from $_POST['myvar']. Oh, and don't use double quotes, use single quotes inside an array.

If yacoubisaac wants to use double quotes in his array indices he's perfeclty free to use double quotes in his array indices - what difference does it make?

Trivialities aside: now for the real problem. I assume that the action= attribute on the form is present in the real code, otherwise the next page would never happen. So:

What does print_r($HTTP_POST_VARS) produce (which prints the contents of an array) when inserted at the top of the page? After the includes (where the echo $ctr test is now)?

Does using $_POST[] make a difference? If so, is this use of $HTTP_POST_VARS inside a function (where it would need to be declared global?) I presume not, from the code given.

If feasible, try temporarily changing the form field types to text to keep an eye on their contents. Remember that the form fields on the second page won't have any values (but I am wondering why the form needs to be on both pages).

Are you using Microsoft's PWS? I understand that that has been found to be buggy with regard to form posts (but then, it's only a toy web server).

Thanks for all the help.

I never had the action set to do anything. I was clicking an image that was wrapped in an HREF="page.php". I just assumed that it would have passed on the variables but it didn't. So I made a script that sets the action attribute to the proper php page and then call submit.
