Question

我是新蛋糕php.I必须在数据库中输入多个城市ID，使用逗号分隔符，如10,11,12，其中10,11,12是城市ID

当我使用此代码时

 **<?php
          echo $form->input('city_id', array('options' => $city, 'class'=>'input_box2',
'empty' => 'Please select a city'), null, array('id' => 'city_id', 'label' => 'City'
          ));**

我可以一次插入一个城市ID，但我需要使用逗号分隔符插入多个城市ID。我正在使用以下代码，但它不起作用。请帮助

    **<?php
        echo $form->input('city_id', array('options' => $city, 'type'=>'select','multiple'
=> 'true', 'empty' => 'Please select  city'), null, array('id' => 'city_id', 'label' => 'City'));**

您需要修改控制器中的POST数据：

CakePHP 2.x中的

$city_ids = Set::extract('/YourModel/city_id', $this->request->data);        
$this->request->data['YourModel']['city_id'] = implode(",", $city_ids);

CakePHP 1.x中的

$city_ids = Set::extract('/YourModel/city_id', $this->data);        
$this->data['YourModel']['city_id'] = implode(",", $city_ids);

Cake php中的多选列表框
