WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I have a form that allows any registered user to submit a post (it's a custom post type - forum related), and I'm using wp_insert_post() to insert it into the db.

From what I've seen in this function a sanitize_post() function is run automatically, but I think this only handles db escaping and such.

So how do I sanitize the input data the same way as the wp-admin editor does? I mean apply the kses filter and all the other stuff...

When a post is created/edited from the admin, edit_post() is called.

This function simply collects all the $_POST arguments and passes them to wp_update_post().

wp_update_post() then does some more logical checks and passes the data along to wp_insert_post().

wp_insert_post() calls sanitize_post(), which does all the heavy duty sanitization.

So, yes, wp_insert_post() is the correct way to do it.

but I still can submit any type of HTML, like <script> etc. so wp_filter_kses() is not applied to the post_content from wp_insert_post() ? In the admin it seems it is. –  onetrickpony Feb 16 '11 at 18:09
    
First, make sure the user you're logged-in as does not have the 'unfiltered_html' capability. –  scribu Feb 16 '11 at 22:05
    
can editors post unfiltered html? –  onetrickpony Feb 17 '11 at 3:27
    
You can find out with a plugin, such as Capability Manager –  scribu Feb 17 '11 at 14:32

Otto did a blog about using kses last year, see if that helps.
