Webdialog connect to PHP

You could make an AJAX request.

Btw, what happens when you use #post_url?

It gives me blank page and doesn't transfer
data
array to that page

I will try to look at AJAX thanks.

thomthom

hm.. well, at least AJAX will work. I've used that myself.

There is an other possible hack - however more complicated - to use GET variables instead of POST:

You open index.php in your webdialog.
index.php contains the Javascript to get the Ruby variables
You make a Javascript redirect with the variables appended to the URL as GET variables.
You have the GET variables available at the .php side.

Not a usual solution but works.

Thanks I thought about it too, but could you pleas post small code example ?

A possible exampele for myfile.php:


<?php if(isset($_GET['v'])) ; ?>
	The variable; <?php echo $_GET['v']; ?>
<?php else ; ?>
<html>
	<head>
		<script type="text/javascipt">
			var v=[ your function to get the ruby variables ];
			function myredirect() {
				window.location='http://myserver.com/myfile.php?v=' + v;
			}
			window.onload=myredirect();
		</sript>
	</head>
	<body>
	</body>
</html>
<?php endif; ?>

Something like

First page, js :

window.location.href = "http://www.domain.com/page.php?param=foo"

Second page, php :

<?php echo $_GET['param']; ?>

(Returns "foo")

EDIT : Well, too slow

Gábor's exemple is similar to the behavior of an HTTP redirect (window.location.replace("");)
While mine is similar to the behavior of clicking on a link (window.location.href = "";)

Depends on what you want to do.

Thanks Gábor and jiminy-billy-bob I combined both scripts and now understand how to do it

Does some one know how big(length) array ("v") I can send through ?
window.location='http://myserver.com/myfile.php?v=' + v;

thomthom

That would be limited by the URL scheme. I cannot remember the maximum size...

Gábor

Don't forget to urlencode/urldecode the variable if it contains special characters...

But big data like this you should go with POST instead of GET
