everything is OK, but when i was saving, the function get_blogspot_url($_POST[$dt])
didn’t work because $_POST[$dt].
When i replace get_blogspot_url($_POST[$dt]) with,
get_blogspot_url('<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-sfO5YNlgW0Y/UFCaPberRcI/AAAAAAAAANM/1ccm6QRHxLM/s1600/0000.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://4.bp.blogspot.com/-sfO5YNlgW0Y/UFCaPberRcI/AAAAAAAAANM/1ccm6QRHxLM/s320/0000.png" width="240" /></a></div>

<br />')
it works, so i think $_POST[$dt] have problem, can you help me?
You can download php file: https://dl.dropbox.com/u/52812919/chap-meta.rar 🙁
