You’re not closing the first if tag.
/* Update user information. */
if ( !empty( $_POST['url'] ) ){
update_user_meta( $current_user->id, 'user_url', esc_url( $_POST['url'] ) );
} else{
delete_user_meta( $current_user->id, 'user_url');
}
Also, you should use esc_url_raw
on a raw url and then if you’re echoing into the html use esc_url
. You also shouldn’t save esc_attr
values. This is to be used when echoing as an html attribute value. Instead, try wp_filter_kses()
.
