在外部php文件Joomla中包含Jfactory类

mysql

我正在为Joomla编写模块,这时我真的需要能够使用Jfactory连接到数据库。通常一个人可以简单地使用$db = JFactory::getDBO();,但是PHP错误告诉我不包含JFactory类。 所以现在我需要知道如何包括这个JFactory类
。我尝试了一些在互联网上发现的建议,但都没有成功。这是代码(独立运行时完​​美)

    <?php
// server info
$server = 'localhost';
$user = 'ss';
$pass = 'oo';
$db = 'ss';

$connection = mysql_connect($server, $user, $pass)  or die ("Could not connect to server ... \n" . mysql_error ());
 mysql_select_db($db) or die ("Could not connect to database ... \n" . mysql_error ());


if(isSet($_POST['username']))
{
$username = $_POST['username'];
$username = mysql_real_escape_string($username);
$sql_check = mysql_query("SELECT Username FROM users WHERE Username='$username'");

if(mysql_num_rows($sql_check))
{
echo '<font color="#cc0000"><STRONG>'.$username.'</STRONG> is already in use.</font>';
}
else
{
echo 'OK';
}

}

?>

希望您能解决我的问题。您的帮助将不胜感激。

尝试1

<?php

include('../../../../configuration.php');

include('../../../../libraries/joomla/factory.php');

$config =& JFactory::getConfig();

// server info
$server2 = $host;
$user2 = $user;
$pass2 = $password;
$db2 = $db;

$connection = mysqli_connect($server2, $user2, $pass2)  or die ("Could not connect to server ... \n" . mysqli_error ());
 mysqli_select_db($db2) or die ("Could not connect to database ... \n" . mysqli_error ());


if(isSet($_POST['username']))
{
$username = $_POST['username'];
$username = mysql_real_escape_string($username);
$sql_check = mysql_query("SELECT username FROM #__users WHERE username='$username'");

if(mysql_num_rows($sql_check))
{
echo '<font color="#cc0000"><STRONG>'.$username.'</STRONG> is already in use.</font>';
}
else
{
echo 'OK';
}

}
?>

但这也不起作用。

尝试2(成功)

include('../../../../configuration.php');
$jc = new JConfig();
$table = 'users';
$users = $jc->dbprefix . $table;
// connect to the database
$mysqli = new mysqli($jc->host, $jc->user, $jc->password, $jc->db);

现在一切正常。现在唯一的事情是:安全。我不太确定这是黑客证明。有人可以评论吗?谢谢 :)

我敢肯定您会发现,但也许对其他人有用

要使用joomla数据库类(即使您不建议使用:)),也需要先定义三个常量,例如:

define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
define( 'JPATH_BASE', $_SERVER[ 'DOCUMENT_ROOT' ] );

然后,您需要包括三个文件,例如:

require_once( JPATH_BASE . DS . 'includes' . DS . 'defines.php' );
require_once( JPATH_BASE . DS . 'includes' . DS . 'framework.php' );
require_once( JPATH_BASE . DS . 'libraries' . DS . 'joomla' . DS . 'factory.php' );
$mainframe =& JFactory::getApplication('site');

编辑

您只能包含两个文件,例如:

define( 'JPATH_BASE', $_SERVER[ 'DOCUMENT_ROOT' ] ); // define JPATH_BASE on the external file
require_once( JPATH_BASE . DS . 'libraries' . DS . 'import.php' ); // framework
require_once( JPATH_BASE . DS . 'configuration.php' ); // config file

最后使用joomla类,例如:

$db = JFactory::getDBO();
