Sending webix form to postform.php ... but my print_r($_POST); returns empty array..

Below is the form post function… how do I output webix form variables after webix validation?

				{ 
					view:"form", width:200, scroll:false,
					cols:[
						{ view:"button", label:"Submit", height:30, width:100, click:function(){				
							if ($$('publisherCreateForm').validate()) {
								webix.message("Form has been validated.");
								//webix.ajax().post("postform.php", form.getValues(), callback);
								//webix.ajax().post("postform.php");
								webix.ajax("postform.php", function(text){
									webix.message(text); // server side response
								});
								//webix.ajax("postform.php", 
								//	{ error:function(text,xml,XmlHttpRequest){ webix.message("Error");},  // server side response
								//	{ success:function(text,xml,XmlHttpRequest){ webix.message("Success");}  // server side response
								//});
							}
							else
								webix.message({ type:"error", text:"Form is NOT complete." });
								// onAfterValidation takes care of displaying missing/invalid field inputs
							}}
					]
				}

Hi everyone: I fixed the problem… in the ajax.post() parameters … Thank you
