I can't tell you what is wrong, what you have looks superficially OK, so I suspect there is something else happening (or not happening) outside of what you have posted.

My favourite diagnostic code is:
echo '<pre>';
echo "********************\n";
echo htmlentities(print_r($_POST,true));
echo "\n====================";
echo '</pre>';

You could also use the Chrome or Firefox developer console to record network actions and look at the posts and responses.

In php $_POST is a global, so you just use it.

On the web page, providing you have all the jQuery, clicking submit should simply send the value in the relevant part of the $_POST array. You shouldn't need any jQuery to submit the form (unless you are doing it by ajax, or are running the combobox with ajax).

Hence my note about looking at the network traffic in the developer console. That will tell you whether the form is actually being submitted fully and what is actually being posted to the server.
