I have added a meta box that will list specific post type posts, and on save it will save a meta key with selected post id, but the problem is that it rewrites the permalink of the post to consider the selected post as its parent, which i don't want to, i just need to store the selected post id. Where is the problem here:

Actually the problem is that i was giving the select option a name of "parent_id", which for some how automatically used as post parent, but once i changed it to other name it worked.
Working code:

function hfx_register_meta_boxes() {
add_meta_box( 'select_hfx_workshop', __( 'Workshop for', HFX_DOMAIN ), 'hfx_select_workshop_parent_meta_box', 'forum', 'side','core');

add_action( 'add_meta_boxes_forum', 'hfx_register_meta_boxes' );
function hfx_select_workshop_parent_meta_box(){
global $post;
$selected = '';
wp_nonce_field( 'select_workshophfx_box_action', 'select_workshophfx_box' );
if(get_post_meta( $post->ID, 'workshop_id', true )){
$selected = get_post_meta( $post->ID, 'workshop_id', true );
}
if(post_type_exists( 'product' )){
$workshopsfx = get_posts(
array(
'post_type' => 'product',
'orderby' => 'title',
'order' => 'ASC',
'numberposts' => -1
)
);
if ( !empty( $workshopsfx ) ) {
echo '<select name="workshop_id" class="widefat">';

foreach ( $workshopsfx as $workshop ) {
printf( '<option value="%s"%s>%s</option>', esc_attr( $workshop->ID ), selected( $workshop->ID, $selected, false ), esc_html( $workshop->post_title ) );
}
echo '</select>';
}
}
}
function hfx_save_meta_box( $post_id ) {
if ( !isset( $_POST['select_workshophfx_box'] ) || !wp_verify_nonce( $_POST['select_workshophfx_box'], 'select_workshophfx_box_action' ) ){
return;
}

return;
