copied!<p>Ajax, in addition of being a hero of the trojan war according to greek mythology... is the technology you need, and also your friend.</p> <p>I recommend to use jQuery [As Barry has posted faster than me, because I wanted to make sure I got the mythology reference right...]</p> <p>And as MaxArt has pointed out, there are actually two greek heroes named "Ajax", both did participate in the trojan war (and both in Homer's Iliad).</p> <hr> <p>You can use jQuery like so:</p> <pre><code> <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"> </script>  <script type="text/javascript"> function doButtonStuff() { //Use jQuery to "hide some contents" $('#stufftohideId').hide(); //stufftohideId identifies what to hide //set the url of the web page that will take this info on your server var ulr = "http://localhost"; //The following part will fail if you cannot connect to the server $.post( url, {text: $('#textboxId').val()}, //textboxId identifies the textbox function (data) { //data is what the server responded //do something with data, for instance: alert(data); } ); } </script> <input type="text" id="textboxId"></input> <input type="button" onclick="doButtonStuff();" value="Click Me"></input> <div id="stufftohideId"> <p> This is an example of something to hide. </p> </div> </code></pre> <p>You will get on the server side, of the web page with the url you passed like so:</p> <pre><code><?php $text = $_POST['text']; ?> </code></pre> <p>Make sure to verify the request method, for example:</p> <pre><code><?php if ($_SERVER['REQUEST_METHOD'] == 'POST') { $text = $_POST['text']; //do something with $text, for instance: echo $text; } ?> </code></pre> <p>And also to validate and sanitize the input. If a session is required verify that too. Whatever the server returns, will be recieved in the client side.</p>
