ユーザ名を確認する可用性問題

Question

Joomla TPJOBSコンポーネントには新機能が追加されていますが、これは正常/完全/有効コンポーネントではありませんが、可用性チェッカーはユーザ名を追加するだけですが、このコンポーネントでは

私のJoomlaのコンポーネントディレクトリがです：\ public_htmlの\コンポーネント

編集 tpjobs.html.php（出）とusername_validate.php（作成）

私のJavascriptのAJAXコード\ \ com_tpjobs：私たちファイル

// JavaScript <script type="text/javascript"> <!-- //function to create ajax object function pullAjax(){ var a; try{ a = new XMLHttpRequest() } catch(b) { try { a = new ActiveXObject("Msxml2.XMLHTTP") } catch(b) { try { a = new ActiveXObject("Microsoft.XMLHTTP") } catch(b) { alert("Your browser broke!"); return false } } } return a; } function <?php defined('_JEXEC') or die('Restricted access'); $user = strip_tags(trim($_REQUEST['username'])); if(strlen($user) <= 0) { echo json_encode(array('code' => -1, 'result' => 'Invalid username, please try again.' )); die; } $query = "Select a.username FROM #__users where username = '$user' "; $db =& JFactory::getDBO(); $result = $db->setQuery($query); $available = mysql_num_rows($result); if($available) { echo json_encode(array('code' => 1, 'result' => "Success,username $user is still available" )); die; } else { echo json_encode(array('code' => 0, 'result' => "Sorry but username $user is already taken." )); die; } die; ?>() { site_root = ''; var x = document.getElementById('username'); var msg = document.getElementById('msg'); user = x.value; code = ''; message = ''; obj = pullAjax(); obj.onreadystatechange = function(){ if(obj.readyState == 4) { eval("result = " + obj.responseText); code = result['code']; message = result['result']; if(code <=0) { x.style.border = "1px solid #FF0084"; msg.style.color = "#FF1A00"; } else { x.style.border = "1px solid #008C00"; msg.style.color = "#73880A"; } msg.innerHTML = message; } } obj.open("GET", site_root + "username_validate.php?username=" + user, true); obj.send(null); } //--> </script> <style> #username{border: 1px solid #000;} </style> 

tpjobs.html.phpの下にありますername_validate.php

<?php 
defined('_JEXEC') or die('Restricted access'); 

$user = strip_tags(trim($_REQUEST['username'])); 

if(strlen($user) <= 0)

Answer 1

<?php 
defined('_JEXEC') or die('Restricted access'); 


$user = strip_tags(trim($_REQUEST['username'])); 

if(strlen($user) <= 0) 
{ 
    echo json_encode(array('code' => -1, 
    'result' => 'Invalid username, please try again.' 
)); 
    die; 
} 

// Query database to check if the username is available 
$query = "Select a.username FROM #__users where username = '$user' "; 
// Execute the above query using your own script and if it return you the 
// result (row) we should return negative, else a success message. 

$db =& JFactory::getDBO(); 

$result = $db->setQuery($query); 

$available = mysql_num_rows($result); 

if($available) 
{ 
    echo json_encode(array('code' => 1,

}
