the data provider for the view.
the CSS class name for the container of the emptyText property. Defaults to 'empty'.
the HTML tag name for the container of the emptyText property.
the message to be displayed when dataProvider does not have any data.
whether to enable pagination. Note that if the IDataProvider::pagination property of dataProvider is false, this will be treated as false as well. When pagination is enabled, a pager will be displayed in the view so that it can trigger pagination of the data display. Defaults to true.
whether to enable sorting. Note that if the IDataProvider::sort property of dataProvider is false, this will be treated as false as well. When sorting is enabled, sortable columns will have their headers clickable to trigger sorting along that column. Defaults to true.

- sortableAttributes
the HTML options for the view container tag.
the CSS class name for the container of all data item display. Defaults to 'items'. Note, this property must not contain false, null or empty string values. Otherwise such values may cause undefined behavior.
the CSS class name that will be assigned to the widget container element when the widget is updating its content via AJAX. Defaults to 'loading'.
the configuration for the pager. Defaults to array('class'=>'CLinkPager')
.
String value will be treated as the class name of the pager ('ClassName'
value is similar
to the array('class'=>'ClassName')
value). See CBasePager and CLinkPager
for more details about pager configuration array values.
the CSS class name for the pager container. Defaults to 'pager'. Note, this property must not contain false, null or empty string values. Otherwise such values may cause undefined behavior.
the CSS class name for the summary text container. Defaults to 'summary'.
the HTML tag name for the container of the summaryText property.
the summary text template for the view. These tokens are recognized and will be replaced with the corresponding values:
- {start}: the starting row number (1-based) currently being displayed
- {end}: the ending row number (1-based) currently being displayed
- {count}: the total number of rows
- {page}: the page number (1-based) current being displayed, available since version 1.1.3
- {pages}: the total number of pages, available since version 1.1.3
the tag name for the view container. Defaults to 'div'.

public void init()

public function init()
{
if($this->dataProvider===null)
throw new CException(Yii::t('zii','The "dataProvider" property cannot be empty.'));
$this->dataProvider->getData();
if(isset($this->htmlOptions['id']))
$this->id=$this->htmlOptions['id'];
else
$this->htmlOptions['id']=$this->id;
if($this->enableSorting && $this->dataProvider->getSort()===false)
$this->enableSorting=false;
if($this->enablePagination && $this->dataProvider->getPagination()===false)
$this->enablePagination=false;
}
Initializes the view. This method will initialize required property values and instantiate columns objects.
public void registerClientScript()
|
Registers necessary client scripts. This method is invoked by run. Child classes may override this method to register customized client scripts.
public void renderContent()
|
public function renderContent()
{
ob_start();
echo preg_replace_callback("/{(\w+)}/",array($this,'renderSection'),$this->template);
ob_end_flush();
}
Renders the main content of the view. The content is divided into sections, such as summary, items, pager. Each section is rendered by a method named as "renderXyz", where "Xyz" is the section name. The rendering results will replace the corresponding placeholders in template.
public void renderEmptyText()
|
public function renderEmptyText()
{
$emptyText=$this->emptyText===null ? Yii::t('zii','No results found.') : $this->emptyText;
echo CHtml::tag($this->emptyTagName, array('class'=>$this->emptyCssClass), $emptyText);
}
Renders the empty message when there is no data.
abstract public void renderItems()
|
Renders the data items for the view. Each item is corresponding to a single data model instance. Child classes should override this method to provide the actual item rendering logic.
public void renderKeys()
|
public function renderKeys()
{
echo CHtml::openTag('div',array(
'class'=>'keys',
'style'=>'display:none',
'title'=>Yii::app()->getRequest()->getUrl(),
));
foreach($this->dataProvider->getKeys() as $key)
echo "<span>".CHtml::encode($key)."</span>";
echo "</div>\n";
}
Renders the key values of the data in a hidden tag.
public void renderPager()
|
public function renderPager()
{
if(!$this->enablePagination)
return;
$pager=array();
$class='CLinkPager';
if(is_string($this->pager))
$class=$this->pager;
elseif(is_array($this->pager))

{
$class=$pager['class'];
unset($pager['class']);
}
}

{
echo '<div class="'.$this->pagerCssClass.'">';
$this->widget($class,$pager);
echo '</div>';
}
else
$this->widget($class,$pager);
}
Renders the pager.
protected string renderSection(array $matches)
| ||
$matches | array | the matches, where $matches[0] represents the whole placeholder, while $matches[1] contains the name of the matched placeholder. |
{return} | string | the rendering result of the section |
protected function renderSection($matches)
{
$method='render'.$matches[1];
if(method_exists($this,$method))
{
$this->$method();
$html=ob_get_contents();
ob_clean();
return $html;
}
else
return $matches[0];
}
Renders a section. This method is invoked by renderContent for every placeholder found in template. It should return the rendering result that would replace the placeholder.
public void renderSummary()
|
public function renderSummary()
{
if(($count=$this->dataProvider->getItemCount())<=0)
return;
echo CHtml::openTag($this->summaryTagName, array('class'=>$this->summaryCssClass));

{
$pagination=$this->dataProvider->getPagination();
$total=$this->dataProvider->getTotalItemCount();
$start=$pagination->currentPage*$pagination->pageSize+1;
$end=$start+$count-1;
if($end>$total)
{
$end=$total;
$start=$end-$count+1;
}
if(($summaryText=$this->summaryText)===null)
$summaryText=Yii::t('zii','Displaying {start}-{end} of 1 result.|Displaying {start}-{end} of {count} results.',$total);

));
}
else

'{start}'=>1,
'{end}'=>$count,
'{page}'=>1,
'{pages}'=>1,
));
}
echo CHtml::closeTag($this->summaryTagName);
}
Renders the summary text.
public void run()
|
public function run()
{
$this->registerClientScript();
echo CHtml::openTag($this->tagName,$this->htmlOptions)."\n";
$this->renderContent();
$this->renderKeys();
echo CHtml::closeTag($this->tagName);
}
Renders the view. This is the main entry of the whole view rendering. Child classes should mainly override renderContent method.
