It's hard without some context, but I'm guessing that you should be
looking for your post results in the global $_POST variable, but you're not.
Example:
You've got a form, with an element called "item":
<form method='POST' action='target_url.php'>
<input type='text' name='item'>
<input type='submit' value='Go >>'>
On your target page, the value from the form is going to be in the
$_POST array.
example:
echo $_POST['item'];
Also, if you need to post an array of data via a form, you can have
multiple elements with the same name.
This is commonly used for checkboxes, where you can have multiple
specified values for one field:
<form method='POST' action='target_url.php'>
<input type='checkbox' name='colors[]' value='red'>
<input type='checkbox' name='colors[]' value='blue'>
<input type='checkbox' name='colors[]' value='green'>
</form>
The '[]' at the end of the name tells PHP to compile all the values into
an array for you.
Then, you could do:
foreach($_POST['colors'] AS $color) {
echo $color . ",";
}
Hope that helps,
