找不到JFactory [英] JFactory not found

问题描述

我在Joomla getuser.php中制作了一个外部文件，并将其放置在administrator/getuser.php

I made a external file in Joomla getuser.php and place it at administrator/getuser.php

包含数据库查询

<?php
$q=$_GET["q"];
$db = JFactory::getDBO();
// Create a new query object.
$query = $db->getQuery(true);
$query->select($db->nameQuote('product_name'));
$query->from('#__virtuemart_products_en_gb');
$query->where($db->nameQuote('virtuemart_product_id').' = '.$db->quote($q));
$db->setQuery($query);
$result = $db->loadResult();

  echo "<tr>";
  echo "<td>" . $result['product_name'] . "</td>";
  echo "</tr>";
?>

并使用

and call it from product_edit_information.php using ajax located at administrator/components/com_virtuemart/views/product/tpl/product_edit_information.php

代码为

<form>
<select name="users" onChange="showUser(this.value)">
<option value="">Select a person:</option>
<option value="7745">YA Ali</option>
<option value="7746">Qasim</option>
</select>
</form>
<br />
<div id="txtHint"><b>Person info will be listed here.</b></div>
<script>
function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>

错误是

致命错误:找不到类'JFactory' 第3行上的C:\ xampp \ htdocs \ bc22 \ administrator \ getuser.php

Fatal error: Class 'JFactory' not found in C:\xampp\htdocs\bc22\administrator\getuser.php on line 3

此错误的原因是什么 我如何在joomla中添加外部文件

what is the reason of this error how i add external files in joomla

我也经历了这个，但无法理解... http://docs.joomla.org/Adding_AJAX_to_your_component

i also go through this but cant understand... http://docs.joomla.org/Adding_AJAX_to_your_component

defined('_JEXEC') or die('Restricted access'); 

当我把它放在getuser.php的顶部时，它将给我错误

when i put this at top of getuser.php it will give me error

访问受限

当我echo $q=$_GET["q"]; // output 7745 and 7746

 <option value="7745">YA Ali</option>
 <option value="7746">Qasim</option>

但是在未找到jFactory之后发生错误

but after jFactory not found error occurred

对不起，我的英语不好

推荐答案

您应将此代码添加到代码顶部:

you should add this code in top of your code:

define('_JEXEC', 1);
define('DS', DIRECTORY_SEPARATOR);

if (file_exists(dirname(__FILE__) . '/defines.php')) {
    include_once dirname(__FILE__) . '/defines.php';
}

if (!defined('_JDEFINES')) {
    define('JPATH_BASE', dirname(__FILE__));
    require_once JPATH_BASE.'/includes/defines.php';
}

require_once JPATH_BASE.'/includes/framework.php';
require_once JPATH_BASE.'/includes/helper.php';
require_once JPATH_BASE.'/includes/toolbar.php';

问题在于您不包括Joomla框架，也不使用JFactory.如果任何函数包含错误，则应包括该函数的Joomla路径.
Restricted access问题已通过define('_JEXEC', 1);

the problem is that you don't include Joomla framework and using JFactory. If any function contains error, you should include Joomla path for that function.
Restricted access problem solved with define('_JEXEC', 1);
