为foreach()提供的参数无效

Question

嗨，有人能帮我吗？我上了所有PHP网站的这个失败：

代码通过Joomla 3.4.1中的插件"NoNumber Sourcerer"插入

bool(false) Warning: Invalid argument supplied for foreach() in /var/www/admin/libraries/class.System.php on line 117.

这是class.system.php:的第117行

foreach ($result as $entry) {
    $modulePath = dirname(__FILE__) . '/../modules/' . $entry['DirectoryName'] . '/';
    if (is_dir($modulePath) && $entry['DirectoryName'] != '.' && $entry['DirectoryName'] != '..') {
        if (is_file($modulePath . 'index.php')) {
                require_once $modulePath . 'index.php';
                $class = new ReflectionClass($entry['Class']);
                $module = $class->newInstance();
                $this->modules[] = $module;
                foreach ($module->getActions() as $action) {
                    $this->moduleMappings[$action] = $module;
                }
                if ($entry['IsDefault'] != 0) {
                    //print_R($module);
                    $this->defaultModule = $module;
                }
            }
        }
    }
}

尝试检查$result是否有值，并使用-更新代码

if($result != NULL && is_array($result)) {
    foreach ($result as $entry) {
         // your conditions
    }
}
