Allow site admin to automatically create/Use categories with Same group name

[sbrajesh]

Allow site admins to choose if they want to automatically create/associate categories with the same name as group to the group on group creation.

Any progress on this? Would love for groups to automatically create and be associated with a blog category of the same name. No manual admin or user input required.

Fixed it. For anyone else that comes along I found a solution on their support forum. All this code was taken from this thread: https://buddydev.com/support/forums/topic/blog-categories-for-groups-auto-creating-selecting-cats-for-groups/

Put the code in your bp-custom.php file: https://codex.buddypress.org/themes/bp-custom-php/

Here is all the code together at once:

/**
 * Create a Category with group name and set as BCG category
 * 
 * @param type $group
 * @return type
 */
function bcg_custom_create_group_category( $group ) {
		
	$cat = wp_insert_term( $group->name, 'category' );

	if ( ! is_wp_error( $cat ) ) {
		//insert it to group meta for blog categories
		groups_update_groupmeta( $group->id, 'group_blog_cats', array( 0 => $cat['term_id'] ) );
		
		return array( 0 => $cat['term_id'] );

	} else {
		//is it existing
		$term = get_term_by( 'slug', $group->slug,  'category' );
		if (  $term ) {
			
			groups_update_groupmeta( $group->id, 'group_blog_cats', array( 0 => $term->term_id ) );
			
			return array( 0 => $term->term_id );
		}
	}
	
	
	return false;
	
}

//Blog Categories for Groups, auto category creation and association
function bcg_custom_create_group_name_category( $group_id, $group ) {

	bcg_custom_create_group_category( $group );
}

add_action( 'groups_created_group', 'bcg_custom_create_group_name_category', 10, 2 );

//modify extensions to hide the create/manage screen
function bcg_custom_modify_extension( &$extension ) {
	
	 $extension->enable_create_step = false; // enable create step
	 $extension->enable_edit_item = false; // If 
}
add_action( 'bcg_created_group_extension', 'bcg_custom_modify_extension' );

function bcg_custom_forms_args( $args ) {
	
	$args['tax'] = array();
	
	$cusom_fields = isset( $args['custom_fields'] ) ? $args['custom_fields']: array() ;
	
	$group = groups_get_current_group();
	
	if( empty( $group ) || empty( $group->id ) ) {
		return $args;
	}
	
	$cats = bcg_get_categories( $group->id );
	//if there is no category set
	if( empty( $cats ) ) {
		//create if not exists
		$cats = bcg_custom_create_group_category( $group );
	}
	
	if ( empty( $cats ) ) {
		return $args;
	}
	
	$cusom_fields['_bcg_selected_category'] = array(
		'type'		=> 'hidden',
		'default'	=> $cats[0],
		'label'		=> ''	
	);
	
	$args['custom_fields'] = $cusom_fields;
	$args['post_status'] = 'publish';
	
	return $args;
}
add_filter( 'bcg_form_args', 'bcg_custom_forms_args' );

//set default categorywhen post is being saved
function bcg_add_default_category_to_post( $post_id ) {
	
	$post = get_post( $post_id );
	
	if ( ! $post ) {
		return ;
	}
	
	$custom_fields = isset( $_POST['custom_fields'] ) ? $_POST['custom_fields'] : array();
	
	if ( empty( $custom_fields ) ) {
		return ;
	}
	
	if ( ! empty( $custom_fields[ '_bcg_selected_category'] ) ) {
		
		$term_id = absint( $custom_fields['_bcg_selected_category'] );
		//i know there is a loop here that can allow other categories to be asosciated too
		//to avoid that we need the group id in future
		wp_set_object_terms( $post->ID, $term_id, 'category');
	
	}

}

add_action( 'bsfep_post_saved', 'bcg_add_default_category_to_post' );


//Remove BCG "Disable Blog Categories" checkbox
function bcg_remove_checkbox() {

	if ( has_action( 'bp_before_group_settings_admin', 'bcg_group_disable_form' ) ) {
		remove_action( 'bp_before_group_settings_admin', 'bcg_group_disable_form' );
	}

	if ( has_action( 'bp_before_group_settings_creation_step', 'bcg_group_disable_form' ) ) {
		add_action( 'bp_before_group_settings_creation_step', 'bcg_group_disable_form' );
	}
}
add_action( 'bp_init', 'bcg_remove_checkbox' );

Thank you for sharing the code. I hope it helps others.

If the group gets deleted, is it possible to also automatically delete the associated category that was created for it?
