I have a tutor database (MySQL) which store tutor available subjects, example:- tutor1 available subject = A,B,C tutor2 available subject = A,B tutor3 available subject = A

SearchTutor.php içinde;

<select id="select3" class="medium" name="upsr">
<option selected="selected" value="%">-</option>
<option value="A">A only</option>
<option value="A,B">A and B only</option>
<option value="A,B,C">All Subjects</option>
</select>

DisplayTutor.php içinde;

$subjectin = '';
$subdescription = '';
  if(strlen($upsr) > 1)
 {
  $subjectin .= "'106',";
  if($upsr == "A")
   $subdescription .= "'A',";
  else if($upsr == "A,B")
   $subdescription .= "'A','B',";
  else if($upsr == "A,B,C")
   $subdescription .= "'A','B','C',";
  else
   $subdescription .= "'".$upsr."',";
 }

so.. what i want is, when i choose "A only", the result should be tutor3, because i want "A only", those tutor with A,B,C is not qualify, same goes to when i choose "All Subjects", the result should be tutor1, because only tutor1 have all subjects,

ama benim kodlama, ben bunun yanlış olduğunu biliyorum, orada kimse bana bu çözmeye yardımcı olabilir mi?
