In this paper, the method of implementing the cascading drop-down menu of Yii is described in detail in the following steps:

1. Add the following code to the template:

' id ' = ' task-shop-id ',))?>

In this code, ordersrc_options () reads a drop-down menu first. Call the options method in the ORDERSCR model. The contents are as follows

public static function Options ($hasShop = True) {$model = new self (); if ($hasShop) $model->hasshop (); $models = $model ->findall (); $array = Array (' = ' = ' all '); foreach ($models as $model) {$array [$model->src_id] = $model->src_name;} return $array;}

2. Then add the JS code to the template page to make the content assignment to the second drop-down menu when the first drop-down menu changes.

In this JS code, the implementation calls a program to get the value of the second drop-down menu (call the Actiongetshops method in the controller), any append to the second drop-down menu.

The Actiongetshops method in the controller is as follows:

Public Function Actiongetshops () {$srcId = $_get[' srcid '); $array = Thirdpartinterfaceconfig::options ($srcId); $ Htmlcontent = "All "; foreach ($array as $k = = $v) {$htmlContent. = "{$v} "; } Echo $htmlContent;}
