fsockopen

[flabbyrabbit]

Does anyone know away of submitting POST variables without using a form? I have narrowed it down to "fsockopen" which requires you to create your own connection with the server and create your own header, but im not to sure how it works. Can anyone help??

fsockopen opens a new port on your physical server. Meaning you would create an own server/service by using it. The data will therefore not go through your webserver (port 80/443) anymore.
This new port could also be blocked by many firewalls.

Depending on what you need, an alternative could be an xmlhttp-request.
See topic AJAX without Javascript for more info on xmlhttp-request: ajax-without-javascript-vt8800.html

why don't u use sessions?

[flabbyrabbit]

I needed to keep reloading a php file, without affecting the rest of the page (e.g. no refresh). I ended up using AJAX and they worked a treat, very happy with them. Use them all the time now, thanks leonard.

Ok i do need help with one more thing. How do you send POST variables with AJAX? I currently use:

Code: Select all

function ajaxFunction(req)
{
var xmlHttp;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e)
{
alert("Your browser does not support AJAX!");
return false;
}
}
}
xmlHttp.onreadystatechange=function()
{
if(xmlHttp.readyState==4)
{
document.getElementById('answer').innerHTML = xmlHttp.responseText;
}
}
var lelele = Math.random();
lelele = "http://www.site.co.uk/page.php?lol=" + lelele;
xmlHttp.open("GET",lelele,true);
xmlHttp.send(null);
}

How can i edit this to send POST variables??

Thank you,

One possibility:

add function:

Code: Select all

function addToPost(argument,value)
{
   var check = postString.search(/[=]/);
   if (check != -1)
   { postString += "&" }

   value = escape(value);
   //value = encodeURIComponent(value);
   postString += argument + "=" + value;
}


then use it like:

Code: Select all

   postString = '';
   addToPost('ADDR',document.myForm.ADDR.value);
   addToPost('TEL',document.myForm.TEL.value);

   http_request = getHTTPRequest();
   http_request.onreadystatechange = myJavaScriptResponseFunction;
   http_request.open('POST', './myFunction.php', true);
   http_request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
   http_request.send(postString);
}


cheers!

Ok, im confused or just doing somthing completly wrong.

Code: Select all

<script type="text/javascript">
function addToPost(argument,value)
{
var check = postString.search(/[=]/);
if (check != -1){
postString += "&"
}
value = escape(value);
//value = encodeURIComponent(value);
postString += argument + "=" + value;
}
function ajaxFunction() {
postString = '';
addToPost('user','name');
addToPost('pass','word');
http_request = getHTTPRequest(); //This line messes it up!!!!!!
http_request.onreadystatechange = myJavaScriptResponseFunction;
http_request.open('POST', 'post.php', true);
http_request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
http_request.send(postString);
}
</script>
<a onClick="javascript:ajaxFunction();">RUN</a>

It runs up until "http_request = getHTTPRequest();" then stops. Did you get this from a tutorial/website that i could have look at?? Or you give me the full script to make this thing work.

Thank you,

Sorry. Here you go:

Code: Select all


var postString = "";

function getHTTPRequest()
{
     http_request = false;

     if (window.XMLHttpRequest) { // Mozilla, Safari,...
         http_request = new XMLHttpRequest();
         if (http_request.overrideMimeType) {
             http_request.overrideMimeType('text/xml; charset=ISO-8859-1');
         }
     } else if (window.ActiveXObject) { // IE
         try {
             http_request = new ActiveXObject("Msxml2.XMLHTTP");
         } catch (e) {
             try {
             http_request = new ActiveXObject("Microsoft.XMLHTTP");
             } catch (e) {}
         }
     }

     if (!http_request) {
         alert('could not create XMLHTTP-object');
         return false;
     }
     return http_request;
}


I had outsourced the request to a function.

But if you use PHP, don't you want to use the xajax-library? No need to write your own ajax-javascript with that.
