Answer 1

Add a function bind to the onchange of your select as below:

<select name="Select" required id="Select" onchange="changeSelectValue();">

Add an id to your form:

<form id="my-form" action="sitephp.php" method="post">

Use the following JS code to change your action property depending on the selected value:

function changeSelectValue() {
    var myForm = document.querySelector('#my-form');
    var selectValue = document.querySelector('#Select').value;
    if (selectValue.length > 0) {
        myForm.setAttribute('action', selectValue);
    } 
}

Just change the file1.php , file2.php and file3.php with your files.

If you don't have a JS file attached to the page, wrap the above JS code inside a <script type="text/javascript"></script> and place it at the end of the page before the body end tag.

PS Now you changed your code putting the name of the file to call directly inside the value of the options. In this way you don't need anymore the switch case, and you can directly use the value of the select as the action attribute of the form to use.

Answer 2

It would be better to have one main *.php script where you choose a further course of events that depends on the user's input, for example:

switch ( $_POST['Machine'] ) {
    case 0:
        include 'script1.php';
        break;
    case 1:
        include 'script2.php';
        break;
    case 2:
        include 'script3.php';
        break;
}
