Passing variables from Java Script to PHP

[freeflow]

Hi everyone! Can you tell me how to pass variables from Java Script to a PHP File?


This works with a .js file, but how can I make it work with php.

html + .js file

<body>
<h1>Example</h1>
<div id="geo" class="geolocation_data"></div>
<script type="text/JavaScript" src="geo.js"></script>
</body>
</html>



html + php file - How do I have to change the code above to make it work with
the php file below?

<?php

$geo = 'http://maps.google.com/maps/api/geocode/xml?latlng='.htmlentities(htmlspecialchars(strip_tags($_GET['latlng']))).'&sensor=true';
$xml = simplexml_load_file($geo);

...


Thanks for your help.

You can pass variables / values from js to php in this way: http://www.kavoir.com/2010/07/php-a...m-php-to-javascript-or-javascript-to-php.html

you can just echo the code that returns the value of the variable.

php to javascript is easy since php runs before and you can echo the javascript, if you can make it work on ajax (best solution but a little more complex) then you are on the other side

when I need JS to PHP I usually make a cookie and retreive the data 1 click late or by running a second include with the echo

dude just use a hidden value in the JS

<script type="text/javascript">
var myVar = "<?PHP echo $phpVar; ?>";
</script>
