I am working on a PHP based chat for my own web site and I am using the function fread().
I get Error messages saying that fread() needs 2 peramators and I don’t know what the second is.
The Php script is…
[php]<?php
$target_file = “my_file.txt”;
$target_file_data = $_POST[“firstname”] . “”;
$handle = fopen($target_file, “a+”);
fwrite($handle, $target_file_data);
echo fread($handle);
fclose($handle);
?>[/php]

Ajax Post to PHP and Get Return Data
Your Comments:[/code]
The JavaScript XMLhttpRequest Function.
[hr]
function ajax_post(){
var hr = new XMLHttpRequest();
var url = "../php/myphpscript.php";
var fn = document.getElementById("first_name").value;
var vars = "firstname="+fn;
hr.open("POST", url, true);
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
hr.onreadystatechange = function() {
if(hr.readyState == 4 && hr.status == 200) {
var return_data = hr.responseText;
document.getElementById("status").innerHTML = return_data;
}
}
hr.send(vars);
document.getElementById("status").innerHTML = "processing...";
}
ThankYou :D.
