Cross-domain submission of data from a form?

Question

PHP

I configured .htaccess correctly (in any case, it no longer swears). The scheme is as follows:
Site1 - has a form, its js-handler on Site2, exactly like the form for processing the result.
JS-validation of the form on the site2 side works. But the data is empty and does not come... maybe I made a mistake in the code?

This is how sending data in JS looks like

$.post("http://сайт1/форма.php", { n: n1},
    function(data){	$("#mess").html(data);});

So their acceptance in the form...

$name = mysql_real_escape_string(strip_tags($_POST['n']));  
/*итд, стандартно*/

Am I passing them wrong or is this impossible to implement? There can be no errors in the form, on the site1 itself it is working ... I doubt the method of transmission ..

crossDomain parameter:
true

$.ajax({
    crossDomain: true,
    type:"GET",
    contentType: "application/json; charset=utf-8",
    async:false,
    url: "http://<your domain>/hello",
    data: {projectID:1},
    dataType: "jsonp",                
    jsonpCallback: 'successCallback'
});
