Yii :: app（） - > baseUrl无效

Question

Why

<a id="tray-button"><img id="tray-arrow" src="http://localhost/ric/slideshow/img/button-tray-up.png"/></a>

is working but not this

<a id="tray-button"><img id="tray-arrow" src=<?php Yii::app()->baseUrl.'/slideshow/img/button-tray-up.png'?>/></a>

Provided http://localhost/ric -> is my webroot.

Here is the basepath configuration from my main.php

'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',

Answer 1

You need to "echo" the baseUrl

<a id="tray-button">
  <img id="tray-arrow" src="<?php echo Yii::app()->baseUrl; ?>/slideshow/img/button-tray-up.png" />
</a>
