Quoting Ron Piggott <ron.php@xxxxxxxxxxxxxxxxxx>:
Jim what you sent is very helpful.
I had an error message when I submitted the form with a POST
your_cleaning_function
gave me this error:
Fatal error: Call to undefined function: your_cleaning_function()
I am trying to save the ones that were checked to a mySQL table and then
notify the user the database was updated. The first thing that happens
is the code you gave me below. How do I resolve this error? I get the
concept of functions, but this isn't an area of PHP that I have used
before.

In your form, do this
<input type="checkbox" name="components[1][1]">
<input type="checkbox" name="components[1][2]">
Then in PHP do this. This is if the form was sent via POST
<?php
$components = your_cleaning_function($_POST['components']);
foreach ( $components AS $component_id => $packages ) {
foreach ( $packages AS $package_id => $value ) {
// At this point, the only way you would get here is if
// a person was to place a check mark in the check box
// So, one would assume that this component/package
// combo was infact checked.
}
}
?>
The function "your_cleaning_function" is no native PHP function.
Jim just added it to show that you need to filter input data.
To test the script just remove the function call completely. But
remember when you put this in production. You want some sort of input
filtering.
