Yii 1.1.3 设置依赖下拉菜单的选定值 [英] Yii 1.1.3 setting selected value of dependent dropdown
问题描述
我的页面上有 3 个从属下拉列表,用于创建实体.
I have 3 dependent dropdowns on my page for creation of entity.
echo CHtml::dropDownList('OpenLessons[Building]', '', $buildingList,array(
'ajax' => array(
'type'=>'POST',
'url'=>CController::createUrl('ajax/floorList'), //url to call.
'update'=>'#OpenLessons_Floor', //selector to update
)));
echo CHtml::dropDownList('OpenLessons[Floor]','', array(),array(
'ajax' => array(
'type'=>'POST',
'url'=>CController::createUrl('ajax/roomList'),
'update'=>'#OpenLessons_Class_ID',
)));
echo CHtml::dropDownList('OpenLessons[Class_ID]',$model->Class_ID, array());
现在我想在编辑时为他们提供选定的选项:我找到了如何提供选定的选项.我在这里找到了方法.第一个选择有这个代码:
Now I want to give them selected options while edit: I found how to give selected options. I found here how to do it. First select has this code:
<select name="OpenLessons[Building]" id="OpenLessons_Building">
<option value="19">primary school</option>
<option value="6">high school</option>
</select>
所以,我想将它的值设置为高中.
So, I want to set it's value to high school for example.
echo CHtml::dropDownList('OpenLessons[Building]', '', $buildingList,array(
'ajax' => array(
'type'=>'POST',
'url'=>CController::createUrl('ajax/floorList'),
'update'=>'#OpenLessons_Floor',
'options' => array('High school'=>array('selected'=>true)),
//Also tried this 'options' => array('6'=>array('selected'=>true)),
)));
编辑实体时选择的值总是 - 小学.怎么了?更新@Tristup 帮助我设置了第一个下拉列表的值,但是还有两个依赖下拉列表,我遇到了问题.这是我的下一个问题
And chosen value while editing entity is always - primary school. What's wrong? UPDATE @Tristup helped me to set value of first dropdown, but there are two more dependent dropdowns and I have problems with it. Here is my next question
推荐答案
dropDownList 的第二个参数是默认选择.
The second parameter for the dropDownList is the default selection.
Chtml::dropDownList($name, $select, $data)
示例:
$options = array ('0' => 'Select A Value', '1' => 'Tristup','2'=>'Sergey');
echo CHtml::dropDownList('mySelect', '0', $options);
这里的0"是默认选择的值.
here '0' is the value for the default selection.
希望这对你有用.
