在Yii框架视图中使用if-else php代码是否明智？

I am a noob in Yii framework. I am developing an application without using GII CRUD application. Writing my own models and views from scratch.

I would like to know if it is advisable to use if-else php code in Yii framework views?

Also if to use renderpartial, how to submit data to the controller/model and redirect to the existing page.

I tried reading several blogs and documentation. I looked through YII cookbook as well. But I am unable to find the answer to the first question..

My code is as: http://pastebin.com/BQHJvBcA

Pls help.

You should look at Alternative syntax for control structures.

Your views would be more clear with it:

Example from php.net:

<?php if ($a == 5): ?>
A is equal to 5
<?php endif; ?>
