Thank you for your very quick answer. As you may have already guessed, I'm
new to PHP, and struggling with the the most basic operations.
I modifed the 'echo' as suggested and also added a 'printr" statement.
The modified portion of the script is below....
if ($_SERVER['REQUEST_METHOD'] == "POST"):
echo 'Using foreach loop, $_POST array contains:'."<br />";
foreach ( $_POST as $key => $value ) { echo ( $value . "<br />" );}
echo 'Using printr, $_POST array contains:'."<br />";
echo ( "<pre>" );
print_r ( $_POST );
echo ( "</pre>" );
endif;
Clicking on the submit button now produces:
----------------------------------------------------------------------
Request Method: POST
Using foreach loop, $_POST array contains:
Array
Using printr, $_POST array contains:
Array
(
[item] => Array
(
[0] => select item 1
)
)
-------------------------------------------------So what exactly does this
mean?: $Post is an array thatconsists of one item that is also an array,
that being the "item" array consisting of one entry containing the select
string?If so, can I access the "item" array itself? I tried this in the
script but nothing was echoed:echo $item[0]
