Embed a Slideshare presentation to WordPress.org blog

I believe you need the Jetpack plugin installed.

The next problem you’ll run into is that the embedded presentations using the shortcode use the old non-HTML5 Flash markup (and therefore don’t work on Apple devices).

I’ve been looking for a solution for that last problem. I’m about to just write a plugin myself.

Hm interesting. Do you see any new HTML element being added to the source where your presentation should be?

Here’s the function I just wrote to solve the flash problem. You can drop this in your functions.php file (note: I’m assuming you have at least some knowledge of PHP here, well at least enough to know where you need to open and/or close PHP tags. You should have access to FTP or something if anything breaks):

// Unregister existing slideshare shortcode if it exists
if ( shortcode_exists( 'slideshare' ) ) {
	// Remove existing Jetpack version
	remove_shortcode( 'slideshare' );
}

/**
 * Custom Slideshare Shortcode for non-Flash embeds
 *
 * @param array $atts Shortcode attributes. Only required attribute is "id"
 *
 * @return bool|string
 */
function custom_slideshare_shortcode( $atts ) {

	if ( ! array_key_exists( 'id', $atts ) ) {
		// Shortcode didn't contain the id attribute
		return false;
	}

	// Retrieve only the numeric ID of the presentation
	$id = explode( '&', $atts['id'] );
	$id = $id[0];

	// @todo: is this safe?
	$presentationUrl = '//www.slideshare.net/slideshow/embed_code/' . $id;

	$output = '<iframe class="slideshare-embed" src="' . $presentationUrl . '" frameborder="0" marginwidth="0" marginheight="0" scrolling="no" allowfullscreen="allowfullscreen"> </iframe>';

	return $output;
}

// Replace with our new version
add_shortcode( 'slideshare', 'custom_slideshare_shortcode' );
