Question

A select list in a form, I know there’s no problem to pass the option value using post or get. But if I also want to pass the select id value, is it possible and how?
For example:

<form action="Test.php" method="POST">
                <select name="select" id = '1'>
                    <option value="">Select a Status</option>
                    <option value="0">0</option>
                    <option value="1">1</option>
                    <option value="2">2</option>
                    <option value="3">3</option>
                </select>                
                <input type="submit" value="submit"/>
            </form>

And here is the simple print php code:

<?php
    print_r($_POST['select']);
?>

It can print the value of the option that has been chosen, but how to modify the code if I also want to post the id value, which is 1 here. I want to do so because I want the id to become a variable to store some int numbers. Thank you!

The id attribute is designed purely for use in client side code. If you want to pass extra data, then use hidden inputs — that is what they are designed for.

<input type="hidden" name="select_extra" value="1">
<select name="select">
    <option value="">Select a Status</option>
    <option value="0">0</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
</select>
