# Empty paragraphs around figure and figcaption tags when using markdown

I'm using WP 3.8 and Markdown on Save Improved plugin and have following code for outputing HTML5 tags when inserting images via Media Uploader:

function html5_insert_image($html,$id, $caption,$title, align,url, $size,$alt) {
$src = wp_get_attachment_image_src($id, $size, false );$html5 = "<figure>";
$html5 .= "<img src='$src[0]' alt='$alt' />"; if ($caption) {
$html5 .= "<figcaption>$caption</figcaption>";
}
$html5 .= "</figure>"; return$html5;
}
add_filter( 'image_send_to_editor', 'html5_insert_image', 10, 9 );


And in editor output is fine, but on publish my code looks like this:

<p></p>
<figure>
<p></p>
<figcaption>caption_txt</figcaption>
<p></p>
</figure>
<p></p>


If I put div wrapper around figure then there are no empty paragraphs but I'm wondering why figure and figcaption aren't recognized as block elements? Also, this doesn't happen with wp-markdown plugin so it seems it's not markdown problem since both plugins use same parser.

When combining HTML and markdown in other ways, output is fine so I think that's not the issue.

• Please update your installation before proceeding further. Current is 3.8 and as core doesn't support older versions... – kaiser Dec 17 '13 at 15:43
• I finally got around to updating to 3.8 and testing again. Nothing's changed, problem remains... – Teo Dragovic Dec 20 '13 at 15:22
• I guess that's a problem with wpautop(). Have you already asked the plugin author? – kaiser Dec 20 '13 at 15:29
• yes, I posted question wp forums a while ago but got no response wordpress.org/support/topic/… – Teo Dragovic Dec 20 '13 at 15:44
