Thanks.
var_dump ($_REQUEST) displayed the word 'Array'.
I think there is a basic problem with passing array
variables via forms. Look have even tried a simple to
pass a small array variable just to test the
principle, test like this one:-
# p1.php
<?
$row = array
(
"BOOK1" => "PHP",
"BOOK2" => "JAVA",
);
?>
<html><body>
<form method='POST' action='p2.php'>
<input type='hidden' name='row' value=$row>
<input type='submit' value='Submit' name='submit'>
</form>
</body></html>
#p2.php
<?
$row = $_POST['row'];
foreach ($row as $BOOK => $VALUE)
{
echo $BOOK . ':' . $VALUE;
}
?>
and Im still getting the Warning: invalid arguement
etc..
also:
echo $row; // produced 'Array'
echo $row[0]; // produced 'A'
echo $row [1]; // produced 'r'
and so on..
It baffles me really .. this is now elementary PHP not
working as expected!!!
