Hard to figure out what you're doing... but the key is that you need the client code, plus the server handler.

Your HTML:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.5b1.js"></script> 
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js"></script>  
<script type="text/javascript">
function call_this(data, status, xhr)
{
   alert(data);
}
$(document).ready(function(){
   $('#inlinesubmit_button').click(function(){
      $.ajax({
         type: "POST",
          url: "sync_loading1.php",
         data: {text:$('#textbox').val()},
      success: call_this
      });
   });
 });
</script>

<input type="text" id="textbox">
<button id="inlinesubmit_button" type="button">submit</submit>

sync_loading1.php

<?php
// Perform action.  Maybe you want to log this into a DB.
//   Maybe you want to just print out some text:
echo nl2br('Hello world.  Here was my input:'.$_POST['text']);

This function isnt going to work sadly, you are running an ajax call to an external file, and the external file cant do an alert because its not being viewed by the user. if you want to alert the data of the text field, just do alert($('#textbox').val());

You probably need to wrap it in quotes (' or "), to make it a string.

alert('<?php echo $_POST['text'];?>');

It also appears you are overlooking something with how JavaScript runs (client side) and PHP (server side). They can't directly communicate; PHP can echo JavaScript, and JavaScript can make HTTP requests to PHP files.
