如何用$this-> formSelect()创建这个？
<select multiple>
<optgroup label="a">
<option>1</option>
<option>2</option>
</optgroup>
<optgroup label="b">
<option>1</option>
</optgroup>
</select>
对于Zend_Form_Element_Select(),它就像这样
$multiOptions = array( 'Group A' => array(1 => 'First Value',2 => 'Second Value A),'Group B' => array(3 => 'Third Value'),); $element->setMultiOptions($multiOptions);
请注意,您还有addMultiOption($option,$value)和addMultiOptions($options).只需将值或选项添加到附加数组中即可.
