在CakePHP中使用swfObject
cakephp中插入flash
CakePHP 当前版 本：1.2.0.7962 Final
swfObject 当 前版本：2.1
具体步骤如下：
- 下载swfObject，把swfobject.js放到 /webroot/js 目录下
- 将下面代码保存到 /views/helpers/flash.php

/**

/**
* Wrapper for the SwfObject::embedSWF method in the vendor. This method will write a javascript code
* block that calls that javascript method. If given a dom id as fourth parameter the flash will
* replace that dom object. If false is given, a div will be placed at the point in the
* page that this method is echo'ed. The last parameter is mainly used for sending in extra settings to
* the embedding code, like parameters and attributes. It may also send in flashvars to the flash.
*
* For doucumentation on what options can be sent, look here:
* http://code.google.com/p/swfobject/wiki/documentation
*
* @example echo $flash->renderSwf('counter.swf'); // size set with init();
* @example echo $flash->renderSwf('flash/ad.swf',100,20);
* @example echo $flash->renderSwf('swf/banner.swf',800,200,'banner_ad',array('params'=>array('wmode'=>'opaque')));
* @param string $swfFile Filename (with paths relative to webroot)
* @param int $width if null, will use width set by FlashHelper::init()
* @param int $height if null, will use height set by FlashHelper::init()
* @param mixed $divDomId false or string : dom id
* @param array $options array('flashvars'=>array(),'params'=>array('wmode'=>'opaque'),'attributes'=>array());
* See SwfObject documentation for valid options
* @return string

return $ret ;
}
使用方法：
- 例一：
echo $flash -> renderSwf ( 'test.swf' , 400 , 200 , 'flashy' ) ;
echo '<div id="flashy">没有安装flash插件</div>' ; - 例二：
$flash -> init ( array ( 'width' => 200 , 'height' => 100 ) ) ;< br />
echo $flash -> renderSwf ( 'test1.swf' ) ;< br />
echo $flash -> renderSwf ( 'test2swf' ) ; - 例三：
echo $flash -> renderSwf ( 'flashfiles/fl_countdown_v3_3.swf?mo=1&da=24&snd=off&co=AA3333' , 800 , 250 , false , array ( 'params' => array ( 'movie' => '?mo=1&da=24&snd=off&co=AA3333' ) ) ) ;
