php - Approve post and send the password

I am looking for a way to add my password reset function code the code what it does is that when the mail arrives to the user, click on Confirm and the post is published. (before it was pending)

I just want to click on a link and publish the post and send it to the link to reset the password (to generate it, any other idea is welcome)

Thank you!!

// create an url vor verify link with some variables: key, post id, and email
 $url = add_query_arg( 
array(
'email'=>$author->user_email,
'approve'=>$post->ID),
site_url()
 );

 $content = '<table class="body_bg" style="max-width: 600px; border-radius: 5px;" role="presentation" border="0" width="100%" cellspacing="0" cellpadding="0" align="center" bgcolor="#FFFFFF">

</td>';

 $check = md5( $author->user_email . $post->ID  );
 update_post_meta( $post->ID, '_approve_key', $check);

maybe joining with this code?

 function reset_password1($user, $new_pass) {
        do_action('password_reset', $user, $new_pass);
        wp_set_password($new_pass, $user->ID);

        wp_password_change_notification($user); //i dont want other email more...
  }
