[OpenLayers-Users] OpenLayers.Request problem; where is the data?

[Tim Schaub]

Hey-

Can you write (preferably not all on one line) what you are doing again 
to make the request?  If you are setting the content type, include that. 
  Also, note that you can use the POST function and that you don't need 
the new keyword.  In addition, note that params are about GET and data 
is about POST.

I just set up PHP here and confirmed that the following works:

     var req = OpenLayers.Request.POST({
         url: "my.php",
         data: OpenLayers.Util.getParameterString({foo: "bar"}),
         headers: {
             "Content-Type": "application/x-www-form-urlencoded"
         }
     })


The content of my.php:

     <?php var_dump($_POST); ?>


What I see in the response:

     array(1) {
       ["foo"]=>
       string(3) "bar"
     }


The same answer is given here:

I've put this example up on the Request wiki page:
http://trac.openlayers.org/wiki/Request#Ex.7:IssueaPOSTrequestwithform-encodeddata.

And, this is now a FAQ:
http://faq.openlayers.org/ajax/how-do-i-post-form-encoded-data/

Good luck,
Tim
