Because you are sending a POST request, you need to use $_POST["imagetext"]; in your PHP. Alternatively, you could change it to a GET request with jQuery $.get.

You need to use $_POST["imagetext"] in PHP because you are posting with jQuery. What you are doing is acting like the request was made with GET, but $.post(...) will make a POST request.

The reason echo $_GET["iamgetext"]; doesnt print out anything is because it is not set. At least not by your ajax call.

You have 2 options.

Use echo $_POST["imagetext"];
use $.get() for your ajax call.

$.post("a.php", { imagetext: $("textarea").val() } );
echo $_POST["imagetext"];

You are using the wrong global var, should be like above.
