Отключить текстовую область и кнопку, если ячейка в таблице данных является полем

Я хочу отключить текстовое поле «ICICI BM / DBM EMP_ID» и кнопку «APPROVE» в приведенном ниже коде, если bank_emp_id присутствует в базе данных? Это означает, что если bank_emp_id присутствует в базе данных, пользователь не сможет вводить какие-либо данные в текстовой области, и кнопка останется отключенной, а если id отсутствует, то текстовое поле и кнопка останутся активными.

Пожалуйста, помогите как можно скорее.

<?php
include 'includes/header.php';




if (htmlspecialchars(isset($_GET['sid'])))
{
$sid=htmlspecialchars($_GET['sid']);
$sql = "SELECT * FROM branchdetail WHERE solID= '{$sid}' ORDER BY id DESC LIMIT 1 ";
$result=mysqli_query($connection,$sql);
while($row=mysqli_fetch_assoc($result)){
?>
