"the bigger picture"

[Anon]

My last post was how to know if I have correct access to the CURL library on my server, but then I realized there's another issue.

Basically, When I make a form with an action to another page, if for some reason I would need to redirect the page, the receiving page would not have the form information in it -- in other words, form post info doesn't survive a redirect.

Is there any way to assemble the raw HTTP_POST_VARS info, put it in the header, and then redirect it so the next page has the form stuff?

I KNOW I COULD CHANGE IT TO QUERY STRING INFO BUT THAT DOESN'T SEEM TO BE A PROFESSIONAL OPTION.

thank you,

Here is a script for this..

<?
//A working require or include that passes POST variables to a remote form.
//(VERY IMPORTANT)

// First capture all the post variables and pass them on through the
// kludgey "GET-like" mechanism of PHP

if ($REQUEST_METHOD=="POST")
{

 while(list($key2,$val2) = each($HTTP_POST_VARS)) {
 $val = urlencode($val2);
 $tmp .= $key2. "=" . $val . "&";
 }
 // Remove that last "&"
 $VARS= substr($tmp,0,strlen($tmp)-1);


 if ($SERVER_PORT<>"80"){$PORT=":$SERVER_PORT";}else{$PORT="";}

 $REMOTE = "http://$SERVER_NAME$PORT"."$SCRIPT_NAME?".$VARS;

 //echo $REMOTE;

require ($REMOTE);
}

if ($REQUEST_METHOD=="GET")
{
while(list($key2,$val2) = each($HTTP_GET_VARS)) {
$val = urlencode($val2);
$tmp .= $key2. "=" . $val . "&";
}
// Remove that last "&"
$VARS= substr($tmp,0,strlen($tmp)-1);

 if ($SERVER_PORT<>"80"){$PORT=":$SERVER_PORT";}else{$PORT="";}

 $REMOTE = "http://$SERVER_NAME$PORT"."$SCRIPT_NAME?".$VARS;

// echo $REMOTE;
require ($REMOTE);
}
?>

I tried this and it didn't work, don't know why it would. Basically, it is just requiring a file with a query string included.

This would only work for remote files, but if the remote script references $HTTP_POST_VARS['someFormValue'] vs. $someFormValue, the remote form will be blind to the query string idea you had.

Isn't there some way to put the name=value&name2=value2... pairs into the raw header vs. passing in the querystring, and don't you have to also put "application/x-www-form-urlencoded " in the header somehow?

I do appreciate your help though, and any other ideas.

Sam when would you know that the form needed to be redirected? Basically at what point, based on what the user has chosen or ?

Right now when I do form solutions, the form page is an include file in a parent file, the action goes back to the parent file. The logic is basically:

if(sizeof($HTTP_POST_VARS)>1){
//form submitted, error checking here
if(form is OK){
//show the congrats page
include('congrats.php');
}else{
//show the form again, populated
include('form.php');
}
}else{
//no submission yet, show the form
include('form.php');
}

This works fine for fairly complex forms, but sometimes for an application that is a logical flow where the next form presented depends on the user's choices, it would be good to go to a second page, BUT, the issue is coming back with the collection if they made an error.

So to answer your question, errors get checked on the receiving page, and if error, redirect back to the original page, but again, I don't know how to redirect and keey the form collection because it needs to be placed in the header.
