提问by user2205196
i'm currently a newbie when it comes to the yii framework / php. I would like some assistance creating this Chtml::DropDownList.
我目前是 yii 框架/php 的新手。我需要一些帮助来创建这个 Chtml::DropDownList。

Chtml::dropDownList($name, $select, $data)
I understand that $data is the array of data I will be loading in from my Database.
我知道 $data 是我将从我的数据库加载的数据数组。
But can someone explain to me how $name, and $select truly works. I have a hard time finding documentation that explains this at a extremely dumbdown level.
但是有人可以向我解释 $name 和 $select 是如何真正起作用的。我很难找到在极其愚蠢的级别上解释这一点的文档。
I manage to get this piece of code working, but I would prefer using Chtml::dropdownlist.
我设法让这段代码工作，但我更喜欢使用 Chtml::dropdownlist。
<div class="row">
<?php
echo $form->dropDownList($model, 'id',
Chtml::listData(UsersTeam::model()->findAllByAttributes(array('coachId'=>$model->id)), 'id', 'teamName'),
array('empty'=>'Select Team'))
?>
</div>
I would like to be able to display all teamName for the current user that he is enlisted in.
我希望能够显示他入伍的当前用户的所有 teamName。
I'm currently displaying this in the model view of a User, but the information I need is from UserTeam which holds the teams for the users.
我目前正在用户的模型视图中显示它，但我需要的信息来自为用户保存团队的 UserTeam。
'memberOfTeams' => array(self::MANY_MANY, 'UsersTeam', '{{teamMembers}}(userId, teamId)'),
'coachOfTeams' => array(self::HAS_MANY, 'UsersTeam', 'coachId'),

$nameis the name="mySelect"form value it will have (the one that will be passed if sent as a form i.e. $_POST['mySelect']).
$name是name="mySelect"它将具有的表单值（如果作为表单发送，将传递的值 ie $_POST['mySelect']）。
$selectis the preselected ID. Say you have an array...
$select是预选的 ID。假设你有一个数组...
$options = array('12' => 'Twelve', '10' => 'Ten');
And your dropdown looks like this...
你的下拉菜单看起来像这样......
echo CHtml::dropDownList('mySelect', '12', $options);
Then 'Twelve' will be the preselected item in the dropdown and $_POST['mySelect']will be the value passed when the form is sent.
然后“十二”将是下拉列表中的预选项目，并将$_POST['mySelect']是发送表单时传递的值。
You can add additional html options to each <option>tag, using the fourth parameter CHtml::dropDownListaccepts, like so:
您可以<option>使用第四个参数CHtml::dropDownListaccepts为每个标签添加额外的 html 选项，如下所示：
$htmlOptions = array(
// adds to the select element
'style' => 'cursor: pointer;',
// adds to the actual options
'options' => array(
'12' => array('title' => '12')
)
);
And updating the call to:
并将调用更新为：
echo CHtml::dropDownList('mySelect', '12', $options, $htmlOptions);
The finished list would look like this:
完成的列表将如下所示：
<select name="mySelect" style="cursor: pointer;">
<option value="12" selected="selected" title="12">Twelve</option>
<option value="10">Ten</option>
</select>

You can easily do the same with CHtml::activeDropDownList.
您可以使用 CHtml::activeDropDownList 轻松完成相同的操作。
So your code will look like

<div class="row">
<?php
echo CHtml::activeDropDownList($model, 'id',
Chtml::listData(UsersTeam::model()->findAllByAttributes(array('coachId'=>$model->id)), 'id', 'teamName'),
array('empty'=>'Select Team'))
