Guestbook problem

1

Using: Flash MX 2004

i’ve recently began using the guestbook tutorial, and i’ve been having problems >_<. i’ve narrowed it out to where the problem is in the code

 myXML.sendAndLoad("processXML.php", receiverXML);

the targetobject receiverXML has been giving me problems, such as if i try to post it’ll freeze up the flash with the “flash7 slow script” error. everything’s in the right directory, and i can see the test post made by flashmatazz, but there’s no next button as it is standard on his tutorial. if you wish, here’s the rest of my code.

 var currPage = 0;
var showAmount = 10; // set this to the amount of entries you want to view at a time
previous._visible = false;
createMessage._visible = false;
createButton.onRelease = function(){
this._visible = false;
this._parent.createMessage._visible = true;
if (createMessage.nameField.text == ""){
Selection.setFocus(createMessage.nameField);
}
else if (createMessage.messageField.text == ""){
Selection.setFocus(createMessage.messageField);
}
}
// **** Load XML ****************************
myXML = new XML();
myXML.ignoreWhite = true;
receiverXML = new XML();
myXML.load("guestbook.xml");
myXML.onLoad = function(success){
myXML.contentType = "text/xml";
if (success){
this.showXML();
}
else{
trace("Error loading XML file");
}
}
receiverXML.onLoad = function(){
this.contentType = "text/xml";
_root.currPage = 0;
this.showXML();
}
createMessage.closeButton.onRelease = function(){
this._parent._visible = false;
createButton._visible = true;
}
createMessage.sendButton.onRelease = function(){
var myName = this._parent.nameField.text;
var myMessage = this._parent.messageField.text;
if (myName == ""){
this._parent.errorField.text = "please fill out your name";
Selection.setFocus(this._parent.nameField); 
}
else if (myMessage == ""){
this._parent.errorField.text = "please leave a message";
Selection.setFocus(this._parent.messageField);
}
else {
myXML.firstChild.appendChild(myXML.createElement("entry"));
myXML.firstChild.lastChild.attributes.myName = myName;
myXML.firstChild.lastChild.appendChild(myXML.createElement("myText"));
myXML.firstChild.lastChild.lastChild.appendChild(myXML.createTextNode(myMessage));
myXML.sendAndLoad("processXML.php", receiverXML);
this._parent._visible = false;
createButton._visible = true;
}
}
XML.prototype.showXML = function(){
myGuestbook.scroll = 1;
myGuestbook.htmlText = "";
var numItems = this.firstChild.childNodes.length;
var firstItem = numItems - (currPage*showAmount); 
if (currPage == 0) previous._visible = false;
var lastItem = firstItem - showAmount ;
if (lastItem<=0) {
lastItem = 0;
next._visible = false;
}
myCount.text = "Messages: " + numItems;
if (firstItem == lastItem+1) nowShowing.text = "Showing message " + firstItem;
else nowShowing.text = "Showing message " + firstItem + " to " + (lastItem + 1);
for (i=(firstItem-1); i>= lastItem; i--){
myGuestbook.htmlText += "<B>" + this.firstChild.childNodes*.attributes.myName + "</B> wrote:
";
myGuestbook.htmlText += this.firstChild.childNodes*.firstChild.firstChild.nodeValue + "

";
}
}
previous.onRelease = function(){ 
currPage--;
myXML.showXML();
next._visible = true;
}
next.onRelease = function(){ 
currPage++;
myXML.showXML();
previous._visible = true;
}

and here’s the PHP processXML.php code

 <?php
$file = fopen("guestbook.xml", "w+") or die("Can't open XML file");
$xmlString = $HTTP_RAW_POST_DATA; 
if(!fwrite($file, $xmlString)){
	print "Error writing to XML-file";
}
print $xmlString."
";
fclose($file);
?>

i’ve tried to figure out what’s wrong, but i can’t seem to get it.
