$_SESSION $_POST

[Quinonez]

i set up a multipage form about a month ago using Sessions everything
worked well and i moved forward with working on other pages i just
checked the form to make sure it is all working properly and its giving
me an error:

Warning: Invalid argument supplied for foreach() in
/home/mastersc/public_html/testthis.php on line 24

this is the code:

<?
ksort($_SESSION );
foreach ($_SESSION as $page=>$_POST)
{
echo "<div class=\"h3\">$p age</div><br>";
foreach ($_POST as $field=>$value) <--this would be line 24-->
{
echo "$field: $value<br>";
}
}
?>

any suggestions?

Re: $_SESSION $_POST

Try doing a var_dump or print_r of $_SESSION before your for loop.

I suspect that there's a key => value pair where the value isn't an array.

Is session.auto_st art turned on? Shouldn't you call session_start() first?

This seems a little odd - you're overwriting the superglobal variable $_POST
with the contents of the session array values?

The error basically implies $_POST is not an array at this point. Dump it out
with var_dump/print_r, along with $_SESSION from earlier.
