smarty modifier for FLASH Videos

a handgestrickt customer uses the "Free Video to Flash Converter" for converting his videos to FLV-format. this program also provides a FLASH-file with a very basic player, called player.swf.

this modifier is designed to take a link to an FLV-file and convert it to an HTML-snippet including a FLASH-plugin, with the player.swf, the link as the file-argument and the link-text as the player-title. this modifier is highly configurable.

basically this modifier can also be used for other FLASH-Video-players. only tiny modifications have to be made.

the code:

<?php
function identify_modifier_flvlink2flash () {
        return array (
                'name' => 'flvlink2flash',
                'type' => 'smarty_modifier',
                'nicename' => 'FLV-Link to FLASH',
                'description' => 'Converts a Link to an FLV-Video to a fully FLASH.',
                'authors' => 'Stefan Jelner <info@handgestrickt.biz>',
                'licence' => 'GPL',
                'help' => ''
        );
}

function smarty_modifier_flvlink2flash ($string,$params) {
        $temp = explode(',',trim($params));
        $params = array();
        foreach($temp as $value) {
                $temp2 = explode('=',trim($value));
                $params[trim($temp2[0])] = trim($temp2[1]);
        }
        //default values
        $defaults = array(
                'width' => '320',

}
?>

usage:

because smarty does not provide the ability to pass named arguments to modifiers, we have to do it with a string. the syntax is:

"key1=value1,key2=value2,....,keyn=valuen"

example:

{$foo|flvlink2flash:"width=450,height=338"}
{$foo|flvlink2flash:"width=450,height=338,menu=true"}

parameters:

• width
• height
• noembed_img
• noembed_url
• allowScriptAccess
• classid
• codebase
• type
• pluginspage
• quality
• wmode
• menu
• scale
• player_url
• player_size
• player_aplay
• player_autorev
