PHP development framework Yii Framework tutorial (29) Zii component-Menu example

After introducing the Yii database interface, we will introduce Zii components from this article, including ListView, GridView, and some UI components based on JQuery, such as AutoComplete, DataPicker, Button, Drag and Drop.

This article introduces the usage of Menu menu. CMenu uses Html list to display multi-level menus. Menu configuration is configured through its attribute item. Each menu item includes three main attributes

visible Whether it is visible

active Whether the current menu item is selected,

items submenu items.

In addition, it also includes the following attributes:

label: Optional, menu name, supports the use of HTML tags.

url: Optional, click on the URL link of the menu

template: optional, menu template

linkOptions: array, optional, additional HTML link attributes

itemOptions: array, optional, additional HTML for displaying menu items Attributes.

submenuOptions: array, optional, additionally displays the HTML attributes of the submenu.

Generally, the Menu can be defined in the Layout layout. For example, in this example, modify protected/views/layout/main. php

$this->widget('zii.widgets.CMenu',array(
'items'=>array(
array('label'=>'Home',
'url'=>array('/site/index')),
array('label'=>'About',
'url'=>array('/site/page',
'view'=>'about')),
array('label'=>'Contact',
'url'=>array('/site/page',
'view'=>'contact')),
array('label'=>'Login',
'url'=>array('/site/login'),
'visible'=>false),
),
)); ?>

This example uses CViewAction to display several static pages. The default directory of static pages is the pages subdirectory under the current Controller's View directory. This example creates two static pages about in the pages directory. .php, contact.
To use CViewAction to display a static page, you need to modify the Actions method of the Controller:

public function actions()
{
return array(
'page'=>array(
'class'=>'CViewAction',
)
);
}

In addition, if you want to display the hierarchical tracks (breadcrumbs) of the menu, you can use the CBreadcrumbs component in the Zii component , CBreadcrumbs is generally used with CMenu

breadcrumbs)):?>
widget('zii.widgets.CBreadcrumbs', array(
'links'=>$this->breadcrumbs,
)); ?>

This example uses Yii's default CSS, and the display result is as follows:

If CSS is not used, the display result is as follows:

It can be seen that you need to use the CMenu component together with appropriate CSS to display a beautiful menu.
