php mysql + separate between different select query

Question

I am creating a search form using a drop down list to allow the user to select between three types of search:

by name
by specialization
by location

What is really happening is that the select query or the search form do not display any result. It only works on the search by name query without using any other types

My question is how to separate between these three types or how to make the drop list disable if the user did not select it?

search.php

<?php
session_start();
if($_SESSION['login'] != 'true'){
        header("location:index.php");
    }


   $login = ($_SESSION['login']);
   $userid = ($_SESSION['user_id']);
   $login_user = ($_SESSION['username']);
   $fname = ($_SESSION['first_name']);
   $lname = ($_SESSION['last_name']);
   $sessionaddres =($_SESSION['address']);


require_once('for members/scripts/connect.php'); 

// function for selecting names
function nameQuery(){

  $nameData = mysql_query("SELECT * FROM user") or die("could select database");

  while($record = mysql_fetch_array($nameData)){

     echo'<option value="' . $record['user_name'] .  '">' . $record['user_name'] . '</option>';

  }

}



// function for select by specialization

function specializationQuery(){

$specData = mysql_query("SELECT * FROM specialization");

  while($recordJob = mysql_fetch_array($specData)){

     echo'<option value="' . $recordJob['specialization_name'] .  '">' . $recordJob['specialization_name'] . '</option>';

  }


}

if(isset($_POST['search']))
{


    $Sgov = $_POST['governorate'];
    @$Sdist = $_POST['district'];
    @$Svillage = $_POST['village'];


    // query  search by name
    if(isset($_POST['name']))
    {
        $Sname =$_POST['name'];
    $sql = mysql_query("SELECT first_name, last_name, profile_pic FROM user WHERE user_name ='$Sname'")or die(mysql_error());

    if($sql)
    {
     while($getrow = mysql_fetch_array($sql))
     {
        $firstname = $getrow['first_name'];
        $lastname = $getrow['last_name'];
        $profilepic = $getrow['profile_pic'];

        if($profilepic == "") 
         {
             $profile_pic = "images/default_img.jpg";
         }
         else
         {
             $profile_pic = "userdata/profile_pics/".$profilepic;
         }



         echo "<ul>

         </ul>";
     }
   }
   else
   {
       echo "their was no result!!!!";
   }
  }
}

// search by specialization

if(isset($_POST['specialization']))
{
    $Sspec = $_POST['specialization'];
    $sql = mysql_query(" SELECT first_name, last_name, profile_pic FROM user WHERE specialization = '$Sspec'")or die(mysql_error());
    if($sql)
    {
     while($getrow = mysql_fetch_array($sql))

         else

             $profile_pic = "userdata/profile_pics/".$profilepic;
         }



         echo "<ul>
          <li>

         </ul>";
     }
   }
   else

Answer 1

You could use this way:

...
$Sspec = $_POST['specialization'];
if ($Sspec != '') {
  $w = "WHERE specialization = '".$Sspec."'";
}
$sql = mysql_query(" SELECT first_name, last_name, profile_pic FROM user ".$w)or die(mysql_error());
...
