How to get php page to receive ajax post from html page

Question

I have a very simple form that has an input field for first name. I captured the form data and transmitted it via ajax to a PHP page using the standard jQuery posting method. Ho

Answer 1

In your Ajax function, you're passing the contents of formData to the server, though not as formData but as their original input name.

In this case, you have:

<input type="text" class="form-control" name="firstName" id="firstName" placeholder="First name">

The input's name is firstName, so you need to call $_POST['firstName'] instead of $_POST['formData'].

if (isset($_POST['firstName'])) {
    $ajaxData = $_POST['firstName'];
    echo $ajaxData;
}

The same applies for any other field you would have in your form, so for example, having another input with the name lastName means you'd have to call $_POST['lastName'] to access it.

There were also some misplaced brackets and parentheses in the PHP code which I accommodated above.
