Custom youtube shortcode that uses $content

Question

I wanna make a simple shortcode that returns the youtube link in a specified size and use the content. Something like:

[yt]http://youtu.be/Nl29v5pfxTw[/yt]

I have this code, but I want to simplify it:

    function youtube($atts) {
        extract(shortcode_atts(array(
                "value" => 'http://',
                "width" => '620',
                "height" => '350',
                "name"=> 'movie',
                "allowFullScreen" => 'true',
                "allowScriptAccess"=>'always',
        ), $atts));
        return '<object style="height: '.$height.'px; width: '.$width.'px"><param name="'.$name.'" value="'.$value.'"><param name="allowFullScreen" value="'.$allowFullScreen.'"></param><param name="allowScriptAccess" value="'.$allowScriptAccess.'"></param><embed src="'.$value.'" type="application/x-shockwave-flash" allowfullscreen="'.$allowFullScreen.'" allowScriptAccess="'.$allowScriptAccess.'" width="'.$width.'" height="'.$height.'"></embed></object>';
}
add_shortcode("yt", "youtube");

The problem is that with this code I need to use [yt value="http://youtu.be/Nl29v5pfxTw"] and I want to just use the [yt]$content[/yt]

How I can achieve that?

Thanks

Answer 1

Shortcode functions accept a second parameter which contains the value in between the shortcode opening and closing tags:

function youtube( $atts, $value = 'http://' ) {
    extract( shortcode_atts( array(
        "width" => '620',
        "height" => '350',
        "name"=> 'movie',
        "allowFullScreen" => 'true',
        "allowScriptAccess"=>'always',
    ), $atts ) );
    return '<object style="height: '.$height.'px; width: '.$width.'px"><param name="'.$name.'" value="'.$value.'"><param name="allowFullScreen" value="'.$allowFullScreen.'"></param><param name="allowScriptAccess" value="'.$allowScriptAccess.'"></param><embed src="'.$value.'" type="application/x-shockwave-flash" allowfullscreen="'.$allowFullScreen.'" allowScriptAccess="'.$allowScriptAccess.'" width="'.$width.'" height="'.$height.'"></embed></object>';
}
add_shortcode( 'yt', 'youtube' );

Your callback function needs to accept a second parameter.

function youtube($atts, $content) {
        extract(shortcode_atts(array(
                "value" => 'http://',
                "width" => '620',
                "height" => '350',
                "name"=> 'movie',
                "allowFullScreen" => 'true',
                "allowScriptAccess"=>'always',
        ), $atts));
        return '<object style="height: '.$height.'px; width: '.$width.'px"><param name="'.$name.'" value="'.$content.'"><param name="allowFullScreen" value="'.$allowFullScreen.'"></param><param name="allowScriptAccess" value="'.$allowScriptAccess.'"></param><embed src="'.$content.'" type="application/x-shockwave-flash" allowfullscreen="'.$allowFullScreen.'" allowScriptAccess="'.$allowScriptAccess.'" width="'.$width.'" height="'.$height.'"></embed></object>';
}

I believe that is right. There are examples in the Codex about how to do this.
