The difference between render and renderpartial in Yii, yiirenderpartial


The following are some of the experiences that we end up with when we develop a project at Shun Yi Network.
When rendering the page output.

1.render outputs the contents of the parent template, and embeds the rendered content into the parent template.
2.renderPartial does not output the contents of the parent template. The output is only for the local content of this rendering.

There is also an important difference:

The Processoutput ($output) function is executed by default inside the render function, which registers the components, such as CTreeView, inside the Cclientscript
The desired script for rendering output.

RenderPartial () does not automatically render the output client script by default, it needs to specify the parameters before output:
RenderPartial ($view, $data =null, $return =false, $processOutput =false)
Specifies that Processoutput is true.

For example, to local output CTreeView, with renderpartial for rendering, if the default Processoutput=false output content, does not contain client script
The output content is a normal UL list. No tree-shaped folding effect. After you have actively set Processoutput=true, all client-side scripts will be output in front of the list CTreeView required.

Here are a few of the related functions to use:

Render,renderpartial no longer introduce
Processoutput ()

<?phppublicfunction render ($view, $data =null, $return =false) {if ($this->beforerender ($view)) {$output = $this-&    Gt;renderpartial ($view, $data, true); if ($layoutFile = $this->getlayoutfile ($this->layout))!==false) $output = $this->renderfile ($layoutFile,    Array (' content ' = $output), true);    $this->afterrender ($view, $output);    $output = $this->processoutput ($output);    if ($return) return $output;  else echo $output; }}publicfunction renderpartial ($view, $data =null, $return =false, $processOutput =false) {if ($viewFile = $this    Getviewfile ($view))!==false) {$output = $this->renderfile ($viewFile, $data, true);    if ($processOutput) $output = $this->processoutput ($output);    if ($return) return $output;  else echo $output; } else thrownewcexception (' yii::t ', ' {controller} cannot find the requested view ' {view} '. ', Array (' {' {Controlle R} ' =>get_class ($this), ' {view} ' = $view))); Publicfunction Processoutput ($output) {YiI::app ()->getclientscript ()->render ($output); If using page caching, we should delay dynamic output replacement if ($this->_dynamicoutput!==null&& $this-&    Gt;iscachingstackempty ()) {$output = $this->processdynamicoutput ($output);  $this->_dynamicoutput=null;  if ($this->_pagestates===null) $this->_pagestates= $this->loadpagestates ();  if (!empty ($this->_pagestates)) $this->savepagestates ($this->_pagestates, $output); return $output;}

The above in the actual operation is still more useful, for example, you do not want to use large-form, you can directly transfer variables to the template, you can also make a number of variables into the module into the inside.


Yii framework layouts mainphp want to refer to a page again how to write? Render doesn't seem to work.

Require, if you have to use render (), use RenderPartial ()

Yii how to jump to the parent page by redirect () or render

For example:
1. Yii::app ()->user->returnurl = Yii::app ()->getbaseurl (). " /STEP/SHOW/ID/1 ";
$this->redirect (Yii::app ()->user->returnurl);
2. $this->redirect (Array (' step/show ', ' id ' =>1));
3. $this->render (' index ', array (' post ' = = $questions));
4. $this->renderpartial (' field_show ', Array (' field ' = = $field, ' key ' =>++ $key,));
