Question

I have this code below:
$insert = array();

  for ($i = 1, $n = $_POST['sessionNum']; $i <= $n; ++$i)
  {

      if( $_POST['sessionNum'] == '1'){
            $insert[] = "'" . mysql_real_escape_string($_POST['id']) . ($i == 1 ? '' : $i) . "'";
        }else{
            $insert[] = "'" . mysql_real_escape_string($_POST['id']) . "'";
        }


    $insert[] .= "' ". mysql_real_escape_string( $_POST['textMarks'] ) . "'";
  }

  $sql = "INSERT INTO Session (SessionId, TotalMarks) 
  VALUES (" . implode('), (', $insert) . ")";


  mysql_query($sql);

What the code above does is that it adds a number next to the $_POST[‘id’] depending on what the number is in the $_POST[‘sessionNum’].

For example if $_POST[‘sessionNum’] is ‘3’ and $_POST[‘id’] is VBV, then it will display ‘VBV3’.

But what I want is that if $_POST[‘sessionNum’] is ‘1’, I do not want it to display ‘VBV1’ but instead just ‘VBV’ as it is a single session.

How can this be achieved?

for ($i = 1, $n = $_POST['sessionNum']; $i <= $n; ++$i)
{
  $insert[] = "'" . mysql_real_escape_string($_POST['id']) . ($n == 1 ? '' : $i) . "'";
}
