Ajax post to PHP

[dougalim]

How can I post data from javascript using XMLHTTPRequest and then read the data in PHP. It works using POST with a form and hidden field but I want to send a large XML string without using a form and hidden field leaving the current page in the browser.

What value do I need to use for send

http.open("POST","abc.php",false);
http.send(?)

and how do I read the value in the php script?

Hi

Are you sure this is PHP question ? Because to me seems pure googling for "xmlhttprequest post".

Read the "Using POST method in XMLHTTPRequest(Ajax)" article on OpenJS.

I read the artice and I'm doing basically exactly what the article shows in the POST method section.

The problem i'm having is I do not appear to setting the $_POST[] values using http.send("var=value")

I'm expecting $_POST['var'] to have a value of "value" but it's not, is appears to be null.

if I use http.open("GET","abc.php?var=value",true)
then the $_GET['var'] = value

your question is for the javascript forum. it concerns how you encode and send variables with the POST method, using AJAX.

as a hint, have you tried setting the header properly

http.setRequestHeader("Content-type", "application/x-[URL unfurl="true"]www-form-urlencoded");[/URL]

the params should look like GET without the prepended ?. remember to escape your values before sending them up the pipe.
