Answer 1

Try this

foreach ($vendor_mail as $mail_id)
{
  $data = array(
  'vendormailid' =>$mail_id                 
   );
}

You see in your post you have an array index vendor_name which has 2 indexes. You have assigned that array to $vendor_mail variable which means $vendor_email has now those 2 indexes , you are iterating that array with a foreach() so why get that index from post array again. foreach ($vendor_mail as $mail_id) means every index of $vendor_mail is now $mail_id.. use it.
