php/flash mailing list (solution should be easy)

[woj1s]

I am using a mailing list that works great. The php writes to a text file on my server and im able to open the text file and read the submitted content.

HOWEVER, Everytime I submit content, the php just replaces/rewrites info in the text file instead of adding to it. The solution should be rather easy but I cant find it anywhere.

Actionscript:

function saveText() {
	// create your VAR OBJECT
	sendText = new LoadVars();
	
    // Format variables for PHP
	sendText.nameData = "&nameData="+_root.nameData;
	sendText.emailData = "&emailData="+_root.emailData;
	sendText.newFileName = "text1.txt";
	
    //tell our script what to do WHEN/IF everything goes ok.
	sendText.onLoad = function(success) {
		if (success) {
			//response is the variableName echo'd in the PHP file. 
			_root.saveResponse = sendText.response;
			_root.response_txt.text = sendText.response
		}
    };        
    //finally call the PHP the script
	sendText.sendAndLoad("savedData/saveMyText.php", sendText, POST);
}

Button code:

on (release) {
	_root.nameData = textField1.text;
	_root.emailData = textField2.text;
	_root.saveText(); //function that does sendAndLoad for vars.
}

PHP:

<?php

$newFileName=$_POST["newFileName"];  //Folder HAS to have CHMOD permissions of 777

$nameData=$_POST["nameData"];

$fp = fopen ("text1", "w");

if($fp)
{  fwrite($fp,stripslashes("$nameData\n$emailData"));  // check to see if open was ok.
   fclose($fp);
   echo ("&response=Successfully!");
} else {
echo ("&response=Unsuccessfully!");
}

?>
