How to create a submit button that will disable in previous page after the submit button in current page is submitted?

<!DOCTYPE html>
<html>
<head>
	<meta http-equiv="Content-type" content="text/html; charset=UTF-8" />
	<link rel="stylesheet" href="style.css" type="text/css" media="screen" />
	<link rel="stylesheet" type="text/css" href="print.css" media="print" />
<title></title>
</head>

<body>
<header><h4>Customer Purchase Order</h4></header>
<form action="test3.php" method="post">
<table style="border-collapse:collapse;" width="500" height="206" border="1">

Hi user9791 welcome to the forum

You forgot to post your PHP code, but I’m guessing it’s a problem you’re having with either SESSION or COOKIE functions?

But I don’t have any php code.

Ah, OK. Because you posted in the PHP category (and added a redundant PHP tag) I assumed you were working with PHP code.

You also added a JavaScript tag. But the only JavaScript code you posted is to disable the submit input.

Depending on how critical it is that the submit be disabled (though I think I might go with simply not displaying the form or even the page) you could do this with

a JavaScript Cookie

or a PHP Session

Thanks for the tips. By the way, what if I write a new code which also need to have the same button function but in php code, does it use the same way too?
