In this article, we would like to show you how to make an AJAX POST request with jQuery to the PHP backend in the following way.

1. jQuery AJAX POST request to PHP backend example

ajax.htm file:

<!doctype html>
<html lang="en">
<head>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>
<body>
<pre id="response"></pre>
<script>

    var handle = document.getElementById('response');

    $.ajax({
        type: 'POST',
        url: '/backend.php',
        data: {
            name: 'John',
            age: 25
        },
        success: function (data) {
            handle.innerHTML = 'Response:\n' + data;
        },
        error: function (jqXHR) {
            handle.innerText = 'Error: ' + jqXHR.status;
        }
    });

</script>
</body>
</html>

backend.php file:

<?php

	if ($_SERVER['REQUEST_METHOD'] === 'POST')
	{
		echo "  Sent data to backend:\n";
		echo "   + Name: " . $_POST['name'] . "\n";
		echo "   + Age: " . $_POST['age'] . "\n";
	}
	else
	{
		echo "  Incorrect request method!";
	}

Note: ajax.htm and backend.php files should be placed on php server both.

Result:

jQuery AJAX POST request to PHP backend
jQuery AJAX POST request to PHP backend

2. jQuery AJAX POST request with alternative API to PHP backend example

ajax.htm file:

<!doctype html>
<html lang="en">
<head>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>
<body>
<pre id="response"></pre>
<script>

    var handle = document.getElementById('response');

    var data = {
        name: 'John',
        age: 25
    };

    $.post('/backend.php', data)
        .done(function (data) {
            handle.innerHTML = 'Response:\n' + data;
        })
        .fail(function (jqXHR) {
            handle.innerText = 'Error: ' + jqXHR.status;
        });

</script>
</body>
</html>

backend.php file:

<?php

	if ($_SERVER['REQUEST_METHOD'] === 'POST')
	{
		echo "  Sent data to backend:\n";
		echo "   + Name: " . $_POST['name'] . "\n";
		echo "   + Age: " . $_POST['age'] . "\n";
	}
	else
	{
		echo "  Incorrect request method!";
	}

Note: ajax.htm and backend.php files should be placed on php server both.

Result:
