Question

我想在自定义组件joomla 中设置标记字段，但我不能这样做！

我已遵循本指南https://docs.joomla.org/J3.x:Using_Tags_in_an_Extension#Creating_the_record但仍然无法做到，有人可以尝试对此进行更多解释。

感谢您的所有传入帮助（我绝望:)）我尝试但是我有很多错误，我是joomla的新手，我只想在我的自定义组件中使用标记字段。

修改

所以我从这里开始是因为我不了解其余的https://docs.joomla.org/J3.x:Using_Tags_in_an_Extension#Modify_your_component.27s_table_class_.28or_classes_if_you_have_multiple_tables.29

1º我补充说：

$this->_observers = new JObserverUpdater($this); JObserverMapper::attachAllObservers($this);

对我来说： admin / tables / projectinfo.php （我不知道他是否应该这样做）http://prntscr.com/jf84sb

代码：http://prntscr.com/jf8ac2

2º然后：https://docs.joomla.org/J3.x:Using_Tags_in_an_Extension#Add_tags_to_the_getItem.28.29_method_of_the_model我没有那个，因为是为了joomla 3.1.4。 ????

3º https://docs.joomla.org/J3.x:Using_Tags_in_an_Extension#Add_a_tag_field_to_edit_screens我认为这是好的：D

4º https://docs.joomla.org/J3.x:Using_Tags_in_an_Extension#Prepare_the_view我没有站在一个东西，我只是按Ctrl-P到：

管理员\视图\ projectinfo \ view.html.php

并把它放在这里：

    {

        $this->form = $this->get('Form');

        if (count($errors = $this->get('Errors')))
        {
            JError::raiseError(500, implode('<br />', $errors));

            return false;
        }


        // Set the toolbar
        $this->addToolBar();

        // Display the template
        parent::display($tpl);

        // Set the document
        $this->setDocument();

        $this->item->tagLayout = new JLayoutFile('joomla.content.tags');
        echo $this->item->tagLayout->render($this->item->tags->itemTags);

    }

    /**
     * Add the page title and toolbar.
     *
     * @return  void
     *
     * @since   1.6
     */
    protected function addToolBar()
    {
        $input = JFactory::getApplication()->input;

        // Hide Joomla Administrator Main menu
        $input->set('hidemainmenu', true);

        $isNew = ($this->item->id == 0);

        if ($isNew)
        {
            $title = JText::_('COM_PROJECTINFO_MANAGER_PROJECTINFO_NEW');
        }
        else
        {
            $title = JText::_('COM_PROJECTINFO_MANAGER_PROJECTINFO_EDIT');
        }

        JToolBarHelper::title($title, 'projectinfo');
        JToolBarHelper::save('projectinfo.save');
        JToolBarHelper::cancel(
            'projectinfo.cancel',
            $isNew ? 'JTOOLBAR_CANCEL' : 'JTOOLBAR_CLOSE'
        );
    }
    /**
     * Method to set up the document properties
     *
     * @return void
     */
    protected function setDocument() 
    {
        $isNew = ($this->item->id < 1);
        $document = JFactory::getDocument();
        $document->setTitle($isNew ? JText::_('COM_PROJECTINFO_PROJECTINFO_CREATING') :
                JText::_('COM_PROJECTINFO_PROJECTINFO_EDITING'));
        $document->addScript(JURI::root() . $this->script);
        JText::script('COM_PROJECTINFO_PROJECTINFO_ERROR_UNACCEPTABLE');
    }

}

在此之后，我很困惑，我退出了很多错误，最后一个就是这个：

警告：在第35行的C：\ xampp \ htdocs \ Joomla_3.8.7-Stable-Full_Package \ administrator \ components \ com_projectinfo \ views \ projectinfo \ view.html.php中从空值创建默认对象

注意：未定义的属性：第36行的C：\ xampp \ htdocs \ Joomla_3.8.7-Stable-Full_Package \ administrator \ components \ com_projectinfo \ views \ projectinfo \ view.html.php中的ProjectInfoViewProjectInfo :: $ item

注意：尝试在第36行的C：\ xampp \ htdocs \ Joomla_3.8.7-Stable-Full_Package \ administrator \ components \ com_projectinfo \ views \ projectinfo \ view.html.php中获取非对象的属性“id”
