Setting a post's category

Question

I'm creating new categories with galleries taxonomy :

$wpdb->insert("wpem_terms", array(
    'name'=>'Custom Category',
    'slug'=>'customcategory',
    'term_group'=>0,
));

//id of term
$id = $wpdb->insert_id;

$wpdb->insert("wpem_term_taxonomy", array(
    'term_id'=>$id,
    'taxonomy'=>'galleries',
    'description'=>'',
    'parent'=>'',
    'count'=>'',
));

It's working. And then i'm trying to publish a new post with this newly created category :

wp_insert_post(array(
    'post_author'=>1,
    'post_date'=>date('Y-m-d H:i:s'),
    'post_date_gmt'=>date('Y-m-d H:i:s'),
    'post_content'=>'',
    'post_title'=>'',
    'post_excerpt'=>'',
    'post_status'=>'publish',
    'comment_status'=>'closed',
    'post_name'=>'',
    'post_parent'=>0,
    'post_type'=>'portfolio', // with 'portfolio' custom post type
    'post_category'=>array($id),

));

This is publishing post , it's OK but post's category isn't Custom Category . I think this line invalid :

'post_category'=>array($id),

Any ideas? Also i tried this :

'post_category'=>array(get_cat_ID("Custom Category")),

Try doing this:

$insert_post = wp_insert_post(array(
    'post_author'=>1,
    'post_date'=>date('Y-m-d H:i:s'),
    'post_date_gmt'=>date('Y-m-d H:i:s'),
    'post_content'=>'',
    'post_title'=>'',
    'post_excerpt'=>'',
    'post_status'=>'publish',
    'comment_status'=>'closed',
    'post_name'=>'',
    'post_parent'=>0,
    'post_type'=>'portfolio', // with 'portfolio' custom post type
    'post_category'=>array($id),
));
if( $insert_post ) {
    wp_set_object_terms( $insert_post, intval( $id ), 'galleries');
}

Using wp_set_object_terms you can set the terms for the post in any taxonomy. The first argument is the ID of the post, the second argument is the ID or slug of the term, and the third is the name of the taxonomy. If you use an ID for the term, you must use intval() otherwise it will create a term that is just a number.
