This plugin supports multimarkdown and pandoc as external filters
If you want to use external filters, You need to install those command.

Where can I get pandoc from?

Please refer to

I want to use „sed or something“ as filter, but doesn’t work

Due to security reason, Executable commands are limited. If you want to use another command as filter, need to create custom classes.

Please refer to „custom.example.php“ that is included in this plugin.

When plugin was deactivated, markup are displayed on the posts.

Markup (wrapped in a fallback tag) stored in the post_content column. When disabling the plugin, displays content in post_content column as is as HTML.

If this behavior is unpleasant, check the box to „convert to HTML“ when you save.

Where the data is stored?
  • posts – post_content column of wp_posts table.
  • cache of posts – wp_postmeta table.
  • meta of posts – wp_postmeta table.
  • options – wp_options table.
Why are you store posts’s cache in wp_postmeta?

Some Markdown plugins are store the HTML to the post_content. And store the Markdown to the post_content_filtered.

This approach is superior that doesn’t spew out Markdown even if you disable the plugin. But it has some problem.

  • Revisions and Auto-saved posts format are HTML.
  • Compare Revisions are displayed in HTML.
  • Does not export post_content_filtered column.
  • Bulk edit lose Markdown.

I don’t want to lose markup. For that I made ​​this plugin.

What happens if uninstall this plugin.

Option will be removed. Posts and cache are remains.

What is „<pre class=’wp-markup-collection’>…</pre>“

This is fallback tag. Markup are stored by being wrapped in a fallback tag internally.

When you disable plugin, Markup displayed as HTML in a fallback tag in order to avoid the collapse of the page.
