Hi Ravi

Here is the code I used for buddyblog:

//For Buddyblog Set Minimum and Maximum Characters for Blog Post

add_filter('bsfep_validate_post','buddyblog_custom_validate_title_content',10,2);
 
function buddyblog_custom_validate_title_content($is_error,$post_data){
    //if there is already an error, let us return
    if($is_error)
        return $is_error;
     
     
    //otherwise, let us check for the length of the title/contet
    $min_title_length=50;//assuming 50 characters
    $min_content_length=200;//assuming 200 charactes, will include space
     
    $title = trim($post_data['bp_simple_post_title']);
    $content = trim($post_data['bp_simple_post_text']);
   
    //get the form
     $form_id = $post_data['bp_simple_post_form_id'];
     
     $form = bp_get_simple_blog_post_form_by_id($form_id);
     
    if(strlen($title)<$min_title_length){
         
        $form->message=sprintf('Sorry, The title is too short. The title must be atleast %d characters long.',$min_title_length);
        $is_error=true;
        return $is_error;
    }
     
    if(strlen($content)<$min_content_length){
        $form->message=sprintf('Sorry, The content is too short. The post content must be atleast %d characters long.',$min_content_length);
        $is_error=true;
        return $is_error;
         
    }
         
    return $is_error;
}

//Allow Admin to pick which User blog gets published
add_filter( 'buddyblog_user_can_publish', 'buddyblog_custom_admin_allow_publishing', 10, 2 );
function buddyblog_custom_admin_allow_publishing( $can_publish, $user_id ) {

if(user_can( $user_id, 'list_users' ) )
$can_publish = true;
return $can_publish;
}

//Show Categories as dropdown menu

//buddyblog category as dd
add_filter( 'buddyblog_post_form_settings', 'buddyblog_custom_category_as_dropdoown');
function buddyblog_custom_category_as_dropdoown( $settings ) {

if( !empty( $settings['tax']['category']))
$settings['tax']['category']['view_type'] ='dd'; //view is drop down for categories

return $settings;
}

//Show Post Tags as dropdown menu

//buddyblog post tag as dd
add_filter( 'buddyblog_post_form_settings', 'buddyblog_custom_post_tag_as_dropdoown');
function buddyblog_custom_post_tag_as_dropdoown( $settings ) {

if( !empty( $settings['tax']['post_tag']))
$settings['tax']['post_tag']['view_type'] ='dd'; //view is drop down for categories

return $settings;
}

//Include these categories and post tag for user on buddyblog

/**

 */
function buddydev_filter_buddyblog_form_settings( $settings ) {

	$tax                        = isset( $settings['tax'] ) ? $settings['tax'] : array();
	$tax['category']['include'] = array( 18, 180, 181, 183, 184, 186, 187, 192, 194, 196, 199 );// category ids to include.
