Preview custom post type error

[NickHeurter]

I've installed the plugin and it works fine for published posts. But when I tried to preview a custom post type called 'Projects' which is still in concept then the page gives a 404-error. I can see that the preview url, due to the plugin, changes from /?post_type=projects&p=429&preview=true to /?p=429&preview=true and this causes the error.

Is it possible to solve this so also custom post types can be previewed when not published yet? Thanks already for your help!

Have you seen anything related in your error log? Could you please check for that.

Thanks for your comment!

No nothing to see when debugging. What I do see is that the url of the preview link on the admin page /wp-admin/edit.php?post_type=projectsis already changed to /?p=429&preview=true. In the normal situatie this link shouldn't be touched by your plugin or?

Hi Nick,

Could you please try to comment out the following:

add_filter( 'post_link', array( $this, 'parse_permalinks' ), 10, 3 );
add_filter( 'post_type_link', array( $this, 'parse_permalinks' ), 10, 4 );

See if it helps to bring back the preview link, if so then the problem lies in parse_permalinks function.

Hi @nasyrov ,

When I comment out the second line:
add_filter( 'post_type_link', array( $this, 'parse_permalinks' ), 10, 4 );

The preview links works fine but off course the permalink is no longer changed by your plugin.

Hi @NickHeurter,

Please try to change

} else { // if they're not using the fancy permalink option
	$permalink = home_url('?p=' . $post->ID);
}

to

}

Basically, comment out the else statement.

Hi @nasyrov ,

After removing the else statement the preview permalink changes to %category%/%postname%/?preview=true which results in a 404-error...

Thanks for your help, but this doesn't seems to work :)

Hi @NickHeurter,

Please try to change

else { // if they're not using the fancy permalink option
$permalink = home_url('?p=' . $post->ID);
}

to

else {
$permalink = home_url("?post_type=$post->post_type&p=$post->ID");
}

Its work for me... :) Thanks
