Re: [PHP] How to retrieve form data?
You are correct, and I must apologize.
In addition to the modifications below I added a pair of brackets
to the select clause:
select name=item[]
After removing those the $_POST array looks much better
and I was able print the selected item using
echo Selected item is: .$_POST['item'];
Results now:
---
Using printr, $_POST array contains:
Array
(
[item] = select item 1
)
Selected item is: select item 1

Thank you very much for your responses and willingness to help one who is
just beginning
to learn how to use PHP. I am now on my way.

No, that's not how it should be coming across. Not unless you modified
your original form to send item as an array (like you would do if it was
a multi-select). If your HTML form hasn't changed from how you have it
below, and 'item' is still coming across as an array, you have a problem
sowhere else.
original form?

[PHP] How to retrieve form data?
The first execution of the file below produces the expected output:

Clicking on the Submit button outputs:
Request Method: POST
$_POST array contains:

Why don't I see one of the values from the select item?

Your foreach loop isn't going to print what _you're_ expecting.
foreach ( $_POST as $key = $value ) {
echo ( $value . br / );
}
but print_r() would be much easier...
echo ( pre );
print_r ( $_POST );
echo ( /pre );

Re: [PHP] How to retrieve form data?
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
)
)
