How to let contributors to create a new revision(draft) editing their published posts

2 Views

I’m using a custom post type to let contributors have a personal page on the site.

Any time a user registers on my site a script creates a custom type post that has the registering user as the author.

To moderate users’ entries this post is published by an editor.

I would like users (contributors) to be:

  • unable to add other posts of this custom type;
  • able to edit the already published post they are the author of;
  • and their changes must be approved by an editor before being published.

I’m using User Role Editor to manage roles and capabilities.

Is there a way to do that?

  1. Using Role editor or role scope you can set contributors to edit you custom post type but not publish so every change will be set as draft until approval, and to limit the creation of new posts of your custom post type you can use my plugin Bainternet Posts Creation Limits

    Update

    To force re approval of edits add this code

    add_filter( 'wp_insert_post_data', 're_aprove', '99', 2 );
function re_aprove( $data, $postarr ) {
    //check if current user is not admin
    if ( ! current_user_can( 'manage_options' ) && 'YOUR_CUSTOM_TYPE' === $postarr['post_type'] ) {
        if ( 'publish' === $data['post_status'] ) {
            $data['post_status'] = 'pending';
        }
    }
    return $data;
}

    and change YOUR_CUSTOM_TYPE to your custom post type name.

  2. Mine didn’t work until I added the ’99’ , 2); to the end of the add_filter.

    Here is the reference as to why: http://codex.wordpress.org/Plugin_API/Filter_Reference/wp_insert_post_data

    add_filter('wp_insert_post_data','re_aprove', '99', 2);
function re_aprove( $data , $postarr ){
    global $current_user;
    get_currentuserinfo();
    //check if current user is not admin
    if (!current_user_can('manage_options') && $postarr['post_type'] == "candy-item" ){ 
        if ($data['post_status'] = "publish"){
            $data['post_status'] = "pending";
        }
    }
    return $data;
}

  3. finally i’ve solved using Revisionary plugin,
    http://wordpress.org/extend/plugins/revisionary/
    it’s used to do exacly what I ask in the subject title

    for more detailed control over capabilities (with revisionary already integrated) there is Role Scoper http://wordpress.org/extend/plugins/role-scoper/

    the first one is really easy to setup and use
    the second needs a lot more practice, userinterface it’s a bit confusing, but it’s really powerful
