为什么我会出现"缺少功能"错误？我的功能就在那里!

Question

我得到了"致命的错误:使用包含的代码调用未定义的函数getSContent()"但是......正如您所看到的:我的功能就在那里!

请帮忙.我相信我需要一些睡眠.

class InfoController extends AppController {

    var $name = 'Info';
    var $helpers = array('Html', 'Session');
    var $uses = array();

    function display() {
        $path = func_get_args();

        $section = $path[0];
        $mainMenuActiveElement = $section;
        $sectionContent = getSContent($section);

        $this->set(compact('section', 'mainMenuActiveElement', 'sectionContent'));
        $this->render('/pages/info');
    }

    function getSContent($section) {
        $sectionContent = '';
        switch ($section) {
            case 'bases':
                $sectionContent = 'some content';
                break;
            case 'informacion':
                $sectionContent = 'some other content';
                break;
        }
        return $sectionContent; 
    }

}

您必须指定上下文.与c ++不同的PHP并不this隐含.

$sectionContent = $this->getSContent($section);
