CakePHP: How do I reference a flash asset in my plugin's webroot?

I'm using CakePHP to build a plugin and am trying to add a flash asset to my view. The tag looks like this:

<object type="application/x-shockwave-flash" data="unknown_url" id="VideoPlayback">
    <param name="movie" value="unknown_url" />
    <other params....>
</object>

Unfortunately I don't know what url to point to! Given that my plugin is using standard structure (for CakePHP 1.3x) i would like to access my flash file which is stored here:

app/plugins/my_plugin/webroot/flash/my_flash_file.swf

I know that in the php side /my_plugin/flash/my_f开发者_StackOverflowlash_file.swf gets rewritten to route correctly (this works just fine when I try something like $this->Html->img('URL') ), but I don't know of any Html Helper function to create object tags.

Any help would be appreciated!

You can use $this->Html->url() to create correct URLs.

<object type="application/x-shockwave-flash" data="<?php echo $this->Html->url( ' /my_plugin/flash/my_flash_file.swf' ); ?>" id="VideoPlayback">
    <param name="movie" value="<?php echo $this->Html->url( ' /my_plugin/flash/my_flash_file.swf' ); ?>" />
    <other params....>
</object>

<?php echo $html->url('/webroot/uploadify/uploadify.swf');?>

it will give you link like /your_app_name/webroot/uploadify/uploadify.swf
