Combining GET and POST in PHP for Simultaneous Data Extraction and Database Manipulation

When dealing with web forms, PHP developers often face the need to retrieve data from the user using a combination of GET and POST methods. While it's impossible to use both methods simultaneously in a single HTTP request, PHP provides a workaround that allows you to achieve this functionality.

In your case, you aim to output user inputs (GET) while also accessing a MySQL database based on those inputs (POST). To achieve this, you can modify your code as follows:

<form name="x" method="get" action="x.php">
<input name="year" type="text">

<select name="general">

This code combines the GET (from form x) and POST (from form y with foo=bar appended to the action URL) methods into a single HTML form.

In your PHP script, you can now access both the GET and POST data:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $year = $_GET['year'];
    $general = $_POST['general'];
    
    if ($general == 'YEAR') {
        $result2 = mysql_query("SELECT * FROM student WHERE student.YEAR='$syear'");
        
        // Process database query results
    }
}

By using this approach, you can leverage both GET and POST within a single form, allowing you to retrieve user inputs and access database data in response to the same request.
