Joomla通过PHP脚本添加文章应用程序实例化错误 [英] Joomla add article via php script Application Instantiation Error

问题描述

我创建了一个脚本，以便通过php脚本插入一些文章。此脚本在我的本地计算机（xampp）上运行，但是当我将整个joomla项目部署到Web服务器时，我收到以下错误消息：

i created a script in order to insert some articles via a php script. This script is working on my local machine (xampp), but when i deploy the whole joomla project to my web server i get the following error message:

Error显示错误页面：应用程序实例化错误：应用程序实例化错误

Error displaying the error page: Application Instantiation Error: Application Instantiation Error

通过添加一些回显调用，我能够找到导致错误的行： / p>

By adding some echo calls, i was able to find the line which causes the error:

$app = JFactory::getApplication('site');

现在，我想知道如何解决此问题并使我的功能也可以在Web服务器上运行。

Now i am wondering how to fix this behaviour and make my function also run on the web server.

下面，我将提供系统信息和php函数的开始，直到出现该行为止，这将导致错误消息：

Below i will provide my system informations and the beginning of my php function until the line, which causes the error message:

• joomla版本：3.6.5稳定


• db版本：5.6.34-79.1-log


• php版本：5.6.30-he.0


• 网络服务器：Apache

• joomla version: 3.6.5 Stable
• db version: 5.6.34-79.1-log
• php version: 5.6.30-he.0
• web server: Apache

<?php

echo "STARTING;   ";

// get db connection
include('../includes/mysql.inc.php');

// get all sql querys
include('./autoNewsQuerys.inc.php');

/**
 * Prepare joomla framework to insert article correctly
 */
if (!defined('_JEXEC')) {
    define('_JEXEC', 1);
    define('JPATH_BASE','/is/htdocs/wp1088688_4E1H7PYJFK/www');
    require_once(JPATH_BASE . '/includes/defines.php');
    require_once(JPATH_BASE . '/includes/framework.php');
    defined('DS') or define('DS', DIRECTORY_SEPARATOR);
}

echo "searching app;";
$app = JFactory::getApplication('site');
echo "Found app;";

完整的浏览器输出

开始；搜索应用程序；显示错误页面时出错：应用程序实例化错误：由于 /is/htdocs/wp1088688_4E1H7PYJFK/www/1500AutoNews/autoNews.php已经发送了标头，因此无法启动会话。在第3行。

STARTING; searching app;Error displaying the error page: Application Instantiation Error: Failed to start the session because headers have already been sent by "/is/htdocs/wp1088688_4E1H7PYJFK/www/1500AutoNews/autoNews.php" at line 3.

因此您可以看到错误是由JFactory调用引起的。

So as you can see the error is caused by the JFactory call. 'Found app' is never printed out.

推荐答案

只需复制Joomla index.php 文件转换为另一个文件，然后将 $ app->执行代码替换为您的代码。

Just copy the Joomla index.php file to another file and then replace the $app->execute code with your code.

注意：您不需要包含任何 MySQL 库-由于正在加载Joomla环境，因此您可以访问JDatabase类，该类是数据库抽象层。

Note: You don't need to include any MySQL library - since you are loading the Joomla environment then you have access to the JDatabase class, which is a database abstraction layer.

另一个说明：此文件 autoNewsQuerys.inc.php 可能包含一些问题（也许您正在尝试实例化应用程序，但尚未加载Joomla环境）。您应该将其移到末尾。

Another note: this file autoNewsQuerys.inc.php likely contains some issues (maybe you are trying to instantiate the app there, but the Joomla environment hasn't loaded yet). You should move it to the end.
