本文实例讲述了Yii把CGridView文本框换成下拉框的方法。分享给大家供大家参考。具体实现方法如下：
使用yii的朋友都知道Yii中的CGridView默认显示提文本框了，那么我们要怎么把它转换成下拉框呢?本文就此分析一下解决方法。
默认情况下CGridView会生成一个文本框，但是这并不友好，用户往往希望知道有什么可选的，特别是数据库里存的是数字id的时候，我们希望将数字转换为可读的文本，这时候只需要修改一下表头的"filter"属性就行了，比如:
复制代码 代码如下:
<?php
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'business-grid',
'dataProvider'=>$dataProvider,
'filter'=> Business::model(),
'columns'=>array(
'business_id',
'name',
'package_id'=> array(
'name' => 'package_id',
'value' => '$data->package->package_title',
'filter'=> CHtml::listData(Packages::model()->findAll(array('order'=>'package_title')), 'package_id', 'package_title')
),
'user_id'=>array(
'name' => 'user_id',
'value' => '$data->user->name',
'filter'=> CHtml::listData(Users::model()->findAll(array('order'=>'firstname')), 'id', 'name')
),
'categories' => array(
'name' => 'categories',
'value' => '$data->returnAllCategories(", ",false);',
'filter'=> CHtml::listData(Categories::model()->findAll(array('order'=>'category')), 'cat_id', 'category')
),
'keywords' => array(
'header' => 'Keywords',
'value' => '$data->returnAllKeywords(", ",false);',
),
'links'=>array(
'header'=>'Manage',
'type'=>'raw',
'value'=>'CHtml::link(CHtml::image(Yii::app()->request->baseUrl."/images/admin/approve.png","Approve"), array("approve","id"=>$data->business_id,"item"=>"business"),array("class"=>"approve-link","title"=>"Approve Business"))." ".
CHtml::link(CHtml::image(Yii::app()->request->baseUrl."/images/admin/reject.png","Reject"), array("reject","id"=>$data->business_id,"item"=>"business"),array("class"=>"reject-link","title"=>"Reject Business"))',
),
),
));
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'business-grid',
'dataProvider'=>$dataProvider,
'filter'=> Business::model(),
'columns'=>array(
'business_id',
'name',
'package_id'=> array(
'name' => 'package_id',
'value' => '$data->package->package_title',
'filter'=> CHtml::listData(Packages::model()->findAll(array('order'=>'package_title')), 'package_id', 'package_title')
),
'user_id'=>array(
'name' => 'user_id',
'value' => '$data->user->name',
'filter'=> CHtml::listData(Users::model()->findAll(array('order'=>'firstname')), 'id', 'name')
),
'categories' => array(
'name' => 'categories',
'value' => '$data->returnAllCategories(", ",false);',
'filter'=> CHtml::listData(Categories::model()->findAll(array('order'=>'category')), 'cat_id', 'category')
),
'keywords' => array(
'header' => 'Keywords',
'value' => '$data->returnAllKeywords(", ",false);',
),
'links'=>array(
'header'=>'Manage',
'type'=>'raw',
'value'=>'CHtml::link(CHtml::image(Yii::app()->request->baseUrl."/images/admin/approve.png","Approve"), array("approve","id"=>$data->business_id,"item"=>"business"),array("class"=>"approve-link","title"=>"Approve Business"))." ".
CHtml::link(CHtml::image(Yii::app()->request->baseUrl."/images/admin/reject.png","Reject"), array("reject","id"=>$data->business_id,"item"=>"business"),array("class"=>"reject-link","title"=>"Reject Business"))',
),
),
));
生成type下拉框可以这么写:
复制代码 代码如下:
'type'=>array(
'name' => 'type',
'filter'=>$model->getTypeOptions(),
),
'type'=>array(
'name' => 'type',
'filter'=>$model->getTypeOptions(),
),
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
