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

  /** * @author Alexander Morland * @license MIT * @version 1.2 * @modified 19. nov. 2008 */ class FlashHelper extends AppHelper { var $helpers = array ( 'Javascript' ) ; /** * Used for remembering options from init() to each renderSwf * * @var array */ var $options = array ( 'width' => 500 , 'height' => 500 ) ;   /** * Used by renderSwf to set a flash version requirement * * @var string */ var $defaultVersionRequirement = '9.0.0' ;   /** * Used by renderSwf to only call init if it hasnt been done, either * manually or automatically by a former renderSwf() * * @var boolean */ var $initialized = false ;   /** * Optional initializing for setting default parameters and also includes the * swf library. Should be called once, but if using several groups of flashes, * MAY be called several times, once before each group. * * @example echo $flash->init(); * @example $flash->init(array('width'=>200,'height'=>100); * @return mixed String if it was not able to add the script to the view, true if it was */ function init( $options = array ( ) ) { if ( ! empty ( $options ) ) { $this -> options = am( $this -> options , $options ) ; } $this -> initialized = true ; $view =& ClassRegistry:: getObject ( 'view' ) ; if ( is_object ( $view ) ) { $view -> addScript ( $this -> Javascript -> link ( 'swfobject' ) ) ; return true ; } else { return $this -> Javascript -> link ( 'swfobject' ) ; } }   /** * 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 */ function renderSwf( $swfFile , $width = null , $height = null , $divDomId = false , $options = array ( ) ) { $options = am ( $this -> options , $options ) ; if ( is_null ( $width ) ) { $width = $options [ 'width' ] ; } if ( is_null ( $height ) ) { $height = $options [ 'height' ] ; } $ret = '' ; if ( ! $this -> initialized ) { $init = $this -> init ( $options ) ; if ( is_string ( $init ) ) { $ret = $init ; } $this -> initialized = TRUE ; } $flashvars = '{}' ; $params = '{wmode : "opaque"}' ; $attributes = '{}' ; if ( isset ( $options [ 'flashvars' ] ) ) { $flashvars = $this -> Javascript -> object ( $options [ 'flashvars' ] ) ; } if ( isset ( $options [ 'params' ] ) ) { $params = $this -> Javascript -> object ( $options [ 'params' ] ) ; } if ( isset ( $options [ 'attributes' ] ) ) { $attributes = $this -> Javascript -> object ( $options [ 'attributes' ] ) ; }   if ( $divDomId === false ) { $divDomId = uniqid ( 'c_' ) ; $ret .= '<div id="' . $divDomId . '"></div>' ; } if ( isset ( $options [ 'version' ] ) ) { $version = $options [ 'version' ] ; } else { $version = $this -> defaultVersionRequirement ; } if ( isset ( $options [ 'install' ] ) ) { $install = $options [ 'install' ] ; } else { $install = '' ; }   $swfLocation = $this -> webroot . $swfFile ; $ret .= $this -> Javascript -> codeBlock ( 'swfobject.embedSWF("' . $swfLocation . '", "' . $divDomId . '", "' . $width . '", "' . $height . '", "' . $version . '","' . $install . '", ' . $flashvars . ', ' . $params . ', ' . $attributes . ');' ) ;   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' ) ) ) ;
