ajax post method

[Petran76]

Hello everyone and good u.s. east cost morning.

 

I am starting with ajax and I wrote the following javascript code. It seems to work but in my php script the $_POST array it is empty.Any idea.

 

 

Appreciate.

 

 

function ajaxRegister() {

  var http = false;

 

if(navigator.appName == "Microsoft Internet Explorer") {

  http = new ActiveXObject("Microsoft.XMLHTTP");

} else {

  http = new XMLHttpRequest();

}

 

  http.open("POST", "ajax.php", true);

  http.onreadystatechange=function() {

  if(http.readyState == 4) {

  document.getElementById("email").value = http.responseText;

  }

  }

  var data ="petros=1";

  http.send(data);

}

 

 

<?php

 

foreach ($_POST as $key=>$value)

{echo $key ." ".value;}

echo $_POST['petros'];

 

?>

You need to create post variables, like so (they look the same as get variables):

 

va = 'value1=cat&value2=dog&value3=bird';

 

 

The whole thing:

 

function updateTeams(id, i){
var va = 'value1=cat&value2=dog&value3=bird';
var contentType = "application/x-www-form-urlencoded; charset=UTF-8";
var ajaxRequest;
try{
	ajaxRequest = new XMLHttpRequest();
} catch (e){
	try{
		ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try{
			ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (e){
			alert("Your Browser Doesn't support AJAX.");
			return false;
		}
	}
}
ajaxRequest.onreadystatechange = function(){
	if(ajaxRequest.readyState == 4){
		document.getElementById('email').innerHTML = ajaxRequest.responseText;
	}
}
ajaxRequest.open("POST", 'process/event/addTeam', true);
ajaxRequest.setRequestHeader("Content-Type", contentType);
ajaxRequest.send(va);
}
