PHP搜索多个字段

Question

I'm creating a php webpage search with mysql database ,

as you see on pic above my html search form I'm passing three values through POST .

PHP CODE:

<?php 
$search_name =$this->filter($_POST["name"]);

  $search_location=$this->filter($_POST["location"]);

  $search_speciality=$this->filter($_POST["category"]);

  $sql="SELECT * FROM pro
        WHERE ('pro_fname' LIKE '%".$search_name."%') OR ('pro_speciality' LIKE '%".$search_speciality."%') OR ('pro_location' LIKE '%".$search_location."%') and Pro_category='Doctor'";

  ?>

Problem is I always get same result only the first one on database .

even I let all fields empty .

Pro_category='Doctor' I used it to separate result because I have two categories Doctors and Pharmacies and this search is only performed against DOCTORS

我的意思是尝试正确地封装您的条件

WHERE (condition1 or condition2 or condition3) and condition4
