I'm trying to make this shortcode work but without any success. All attempts gives me a white square.

  function youtube($atts) {
    "value" => 'https://www.youtube.com/watch?v=EhWopzlRwZ8',
    "width" => '475',
    "height" => '350',
    "name"=> 'movie',
    "allowFullScreen" => 'true',
    ), $atts));
    return '<object style="height: '.$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("youtube", "youtube");
  • And what is the problem with it? What do you mean by "white square"? Dec 16, 2013 at 13:21

1 Answer 1


Few remarks about your code:

1) First you should use something like:


instead of the YouTube page:


in your embed code.

2) You can always use the [embed] shortcode if you need to embed YouTube videos:

[embed width="600" height="400"]https://www.youtube.com/watch?v=EhWopzlRwZ8[/embed]

3) You should consider adding a prefix to your shortcode callback, for example macko_tarana_ to avoid function name collision with other plugins.

4) Try to avoid extract(..., use $atts = shortcode_atts(... instead.

5) Consider atting the third parameter to shortcode_atts, i.e. the shortcode name so you can use the shortcode_atts_{$shortcode} filter. More about it here in the Codex.

6) Always escape the input attributes, for example with esc_attr() or esc_url().

Hope this helps.

  • +1 for point #5. I so get fed up by this that I edited Codex and left a note about it.

  • thanks @kaiser. I agree and usually the third attribute is missing when you really need it ;-)
