如何创建一个选择域和下拉菜单–kohana3使用手册
Form::select() 方法能用来创建选择域或下拉菜单。它包含了一些定义选项和设置哪个选项被选中的参数。
echo Form::select(‘name’, array(
‘standard’=>’Standard Shipping’,
‘express’=>’Express Shipping’,
‘international’=>’International’,
));
将返回
<select name=”name”>
<option value=”standard”>Standard Shipping</option>
<option value=”express”>Express Shipping</option>
<option value=”international”>International</option>
</select>
增加第三个参数来定义哪个选项被选中
echo Form::select(‘name’, array(
‘standard’=>’Standard Shipping’,
‘express’=>’Express Shipping’,
‘international’=>’International’,
), ‘express’);
将返回
<select name=”name”>
<option value=”standard”>Standard Shipping</option>
<option value=”express” selected=”selected”>Express Shipping</option>
<option value=”international”>International</option>
</select>
第4个参数接受一个属性数组
echo Form::select(‘name’, array(
‘standard’=>’Standard Shipping’,
‘express’=>’Express Shipping’,
‘international’=>’International’,
), ‘express’, array(‘disabled’=>TRUE));
将返回
<select name=”name” disabled=”1″>
<option value=”standard”>Standard Shipping</option>
<option value=”express” selected=”selected”>Express Shipping</option>
<option value=”international”>International</option>
</select>
配置组
数组配置（第2个参数），键定义了一个配置组的标签，值就是配置组成的数组
echo Form::select(‘product’, array(
‘Fruits’ => array(
‘apple’ => ‘Apple’,
‘orange’ => ‘Orange’,
‘plum’ => ‘Plum’
),
‘Vegetables’ => array(
‘lettuce’ => ‘Lettuce’,
‘parsley’ => ‘Parsley’,
‘cucumber’ => ‘Cucumber’
)
));
…过程…
<select name=”product”>
<optgroup label=”Fruits”>
<option value=”apple”>Apple</option>
<option value=”orange”>Orange</option>
<option value=”plum”>Plum</option>
</optgroup>
<optgroup label=”Vegetables”>
<option value=”lettuce”>Lettuce</option>
<option value=”parsley”>Parsley</option>
<option value=”cucumber”>Cucumber</option>
</optgroup>
</select>
