WRT: How to post to your WordPress using Ajax (+code)

I just finished my “share2” WRT (Web Runtime Toolkit) widget. It allows me to post quick messages to my WordpPress blog or to any blog that uses MetaWeblog API.

Here are some key parts from the script:

Ajax function that sends the requests and gets the result

function ajExec(url, param, callback, isXML) {
    var req = new XMLHttpRequest();
    req.onreadystatechange = function() {
        if (req.readyState == 4 && req.status == 200) {
            if(!isXML && req.responseText != null)
            else if(isXML && req.responseXML != null)
        } else if (req.readyState == 4 && req.status != 200) {

            var err = "Error: "+req.status;
        req.open("POST", url, true);
        req.setRequestHeader("Content-type", "application/x-www-form-urlencoded");


Let’s click on Publish button

function sendButtonClicked(event) {
     saved_username = widget.preferenceForKey("username");
	 saved_pass = widget.preferenceForKey("pass_s");
	 saved_tags = widget.preferenceForKey("tag");
	 saved_server = widget.preferenceForKey("server");
	 pub = blogField.getText();

	ajExec(saved_server,'metaWeblog.newPostMyBlog'+saved_username+''+saved_pass+'titleThis is a postdescription'+pub+'1',showAnswer,1);

The milestone was to find correct XML structure for the query, because the examples from WordPress website and other websites are all wrong. Please see the XML and it’s structure

If you want to run it into your Symbian device – rename it to share2.wgz and upload it to your device. The Symbian will do the rest. Tested on Nokia N95.
