I found both of these snipets on Buddydev

(We have a long list of Categories and we only want members to be able to post to one category of their choice.)

1:

[sourcecode language=”php”]

add_filter(‘buddyblog_post_form_settings’,’buddyblog_my_postform_settings’);
/**
* Filter on the Post form settings which is used by BP Simple Post Form settings
* The settings array is structured like this
*
* array(

* ‘tax’=>array(
* ‘taxonomy_name’=>array(‘taxonomy’=>’taxonomy_name’,//taxonomy_name is the name of taxonomy e.g category, post_tag or your custom taxonomy

* ‘selected’=>array(termid1,termid2),//optional, if you want some terms to be selected by default

function buddyblog_my_postform_settings($settings){

$settings=array(
‘post_type’=> buddyblog_get_posttype(),
‘post_status’=>’draft’,//’publish’|’draft’ etc

‘tax’=>array( //all the associated taxonomies, the below is settings for post category and post tag
‘category’=>array(‘taxonomy’=>’category’,
‘view_type’=>’checkbox’
),
‘post_tag’=>array(‘taxonomy’=>’post_tag’,
‘view_type’=>’checkbox’
)

),
‘upload_count’=>2//how may uploads
);

return $settings;

}

2:

add_filter(‘buddyblog_post_form_settings’, ‘buddyblog_custom_form_settings’);
function buddyblog_custom_form_settings( $settings ){
unset( $settings[‘upload_count’] );
unset( $settings[‘tax’][ ‘post_tag’] );//no need to show posts tag
$category = get_category_by_slug( ‘blog’ );
$settings[‘tax’][‘category’][‘include’] = array( 0 => $category->term_id );
return $settings;
}

I pasted both into my theme functions.php

Number 1. Throws errors and I don’t know how to clean up the code.

Number 2. Was sucessfully added but all posts that are chosen from the list of categories just automatically go to “Uncategorized” Category.

Any help with where to paste the code and what code to paste would be so greatly appreciated.
