How can the issue of transferring the "persnr" along with the selected employee be resolved effectively in the PHP script?

To resolve the issue of transferring the "persnr" along with the selected employee in the PHP script, you can pass the "persnr" value along with the employee ID when submitting the form. This can be achieved by including a hidden input field in the form that stores the "persnr" value and sending it along with the employee ID.

<form action="process.php" method="post">
    <input type="hidden" name="persnr" value="<?php echo $persnr; ?>">
    <select name="employee_id">
        <option value="1">Employee 1</option>
        <option value="2">Employee 2</option>
        <option value="3">Employee 3</option>
    </select>
    <button type="submit">Submit</button>
</form>
