$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        'title',          // display the 'title' attribute
        'category.name',  // display the 'name' attribute of the 'category' relation
        'content:html',   // display the 'content' attribute as purified HTML
        array(            // display 'create_time' using an expression
            'name'=>'create_time',
            'value'=>'date("M j, Y", $data->create_time)',
        ),
        array(            // display 'author.username' using an expression
            'name'=>'authorName',
            'value'=>'$data->author->username',
//HERE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
              'htmlOptions'=>array('class'=>'$data->author->username', 'secondAttribute' => $data->author->id),
//HERE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
        ),
        array(            // display a column with "view", "update" and "delete" buttons
            'class'=>'CButtonColumn',
        ),
    ),
));

在选项中value我可以从PHP添加变量,但是对于选项,htmlOptions这是不可能的.为什么？
如何使用PHP变量创建属性？

SELECT * FROM mytable WHERE date < DATE_SUB(NOW(), INTERVAL 30 DAY);

我怎样才能在 Dotrine 1.2 中做到这一点？

<?php

$array = array('aaa', 'bbb', 'aaa', 'ccc', 'ddd', 'ccc', 'eee');

foreach($array as $a){
   echo $a;
}

有可能像DISTINCT一样使用foreach吗？我想只显示一个值,不重复.这是怎么回事？
