Character in email body if value empty

I have an iPad app that sends data to a PHP page using a post with body method and this works fine. On receiving this data the PHP page sends a notification email with some of the information from the body.

For one user I am getting this:

enter image description here

For some reason the for this user the app does not send the id or email and the body string looks like:

id=&posted_by=admin&email=

The reason for no id or email obviously needs to be fixed but in the meantime I am trying to catch this occurrence in the php page using:

if ($_POST['id'] == '' OR $_POST['id'] === NULL) {

   .... do something...

}

However, this does not work. What would the value of $_POST['id'] be if its value had not been included in the body?

Are you sure this is a $_POST? This looks like a $_GET

You should try $_REQUEST['id'].

The value of $_POST['id'] will be a warning unset variable id when it does not set in the body.

Before getting the value of $_POST['id'] you should use isset() function as:

if(isset($_POST['id']) && !empty($_POST['id'])){

  // do something

}else{

  // else part

}

Note: If you have no idea which type of method used to send data then you should use $_REQUEST['id'], it works for both GET and POST methods.
