后台组件功能开发

后台组件功能开发

配置组件后台子级菜单:

-------------------------

安装组件包前，在后台组件的安装XML里修改submenu节点，安装后会自动在menu与组件节点添加对面的名称。安装组件包后如有修改需求，可以在#__component表中修改submenu

 

-------------------------

 

工具栏(ToolBar):

-----------------------------

JHTML::_('behavior.tooltip');            启动toolbar

         JToolBarHelper::title(JText::_('Newtech'), 'generic.png');

         JToolBarHelper::save();

         JToolBarHelper::custom('publish', 'publish', '', JText::_( 'CC_ENABLED' ), true);

         JToolBarHelper::preferences('com_xxx');        参数设置,对应config.xml

         JToolBarHelper::customX(<task>, 'new.png', 'new.png', 'Create', false);

---------------------------

controller中:

------------------------

 

         $this->setRedirect( 'index.php?option=com_ccNewsletter&controller=newsletter', $msg );// 页面跳转

         JController->getModel();         // 得到对应的model实例，可以获得组件所有model

 

model中:

---------------------------

 

         JModel->getTable    获得表实例，只可以获得对应的table

 

table中：

-------------------------------

         $post = JRequest::get("post");

         JTable->bind($post);                  //对应POST数据更新表

         JTable->check();             //检查数据的正确性

         JTable->store();             //把数据表写入到数据库

 

view中:

------------------------------

 

         JView->getModel              只可以获得对应的model

         JView->get("xxx")    调用对应model的方法

 

------------------------------

 

加在后台模板中的验证脚本：

 

                   <script type="text/javascript">

                   function submitbutton(pressbutton) {

                            var form = document.adminForm;

                            if (pressbutton == 'cancel') {

                                     submitform( pressbutton );

                                     return;

                            }

                            email = form.mail.value; 

                            pattern = /^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(.[a-zA-Z0-9_-])+/; 

                            flag = pattern.test(email); 

                            if(!flag)

                            {

                                     alert("Invalid Email");

                                     return;

                            }

                            submitform(pressbutton);

                   }

                   </script>
