سرم خیلی شلوغه .
، چون برنامه شما رو ندیدم نمی تونم نظر درستی بدم . اما چندتا نکته رو بررسی کن :<?php
require_once(dirname(__FILE__) . '/mainfile.php');
//include(NUKE_INCLUDE_DIR . 'functions_validate.php');
$u = addslashes($_GET['param']);
//// Change these to reflect your database details too: //////////////////
$query = "SELECT username FROM nuke_users WHERE username = '$u'";
$result = sql_query($query);
while($row = sql_fetch_array($result, MYSQL_ASSOC))
{
$checked = $row['username'];
}
//// Now we'll make the requested comparison in lowercase so that it's correct: ///////////////////
$checked = strtolower($checked);
$u2 = strtolower($u);
//// Message to Print if the username is taken: ///////////////////
if($u2 == $checked) { echo "<font color=\"red\"><span class=\"messageboxerror\">$u This User name Already exists</span></font>"; }
//mysql_close($conn);
?>var url = "usercheck.php?param=";
function updateName() {
document.getElementById('checked').innerHTML = "<span class=\"messagebox\">Checking...</span>";
var name = document.getElementById("username").value;
http.open("GET", url + escape(name), true);
http.onreadystatechange = handleHttpResponse;
http.send(null);
}
function handleHttpResponse() {
if (http.readyState == 4) {
results = http.responseText;
var name = document.getElementById("username").value;
if(results == "") results = "<font color=\"green\"><span class=\"messageboxok\">"+name+" Username available to register</span></font>";
document.getElementById('checked').innerHTML = results;
}
}
function getHTTPObject() {
var xmlhttp;
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
xmlhttp = false;
}
}
return xmlhttp;
}
var http = getHTTPObject();
