Action Hook?

[gayanthaSam]

This is not a bug. Is there any Hook we can use to add a function when user clicked the "Update" button?

Custom account tab is a post. WordPress calls these hooks on the post update:

• editpost{$post->post_type}
• edit_post
• post_updated
• savepost{$post->post_type}
• save_post
• wp_insert_post

The plugin uses the save_post_um_account_tabs hook that is a variation of the save_post_{$post->post_type} hook to save tab options. You also can use this hook. See https://developer.wordpress.org/reference/hooks/save_post_post-post_type/
