I am having a lot of trouble posting to the backend using AJAX $POST and php. Basically I want the text entered into the search bar to get posted to a php file and then get echo'd back.

HTML

<body>
    
	<form id="foo">
    <label for="bar">A bar</label>
    <input id="bar" name="bar" type="text" value="" />

    <input type="submit" value="Send" />
</form>

<script src="php.js"></script>

JavaScript

    $inputs.prop("disabled", true);

    // Fire off the request to /form.php
    request = $.ajax({
        url: "/form.php",
        type: "post",
        data: serializedData
    });

    // Callback handler that will be called on success
    request.done(function (response, textStatus, jqXHR){
        // Log a message to the console
        console.log("Hooray, it worked!");
    });

    // Callback handler that will be called on failure
    request.fail(function (jqXHR, textStatus, errorThrown){
        // Log the error to the console
        console.error(
            "The following error occurred: "+
            textStatus, errorThrown
        );
    });

    // Callback handler that will be called regardless
    // if the request failed or succeeded
    request.always(function () {
        // Reenable the inputs
        $inputs.prop("disabled", false);
    });

    // Prevent default posting of form
    event.preventDefault();
});

PHP

<?php
$bar = $_POST['bar'];
?>

URL looks wrong. Do you mean "post.php"?

And what the exact problem?
Do you hit the server side at all?

What are you doing with $bar after getting the value from $_POST? Are you echoing? printing or doing something else?
