problem in pagination clicking

[khan9999]

i rephrase yours answer as look at the pagination code there is 3 pages and 2 pages and 10 pages total means when no search condition is given it created 10 pages but problem is when ist condition is true and in result bottom of 3 pages is created and when i click one of my page data is refresh but in bottom pagination is gone to 10 while it should restrict to similarity when 2nd condition is true 2 pages is created and when i click one of two pages , data is refresh correctly but but in bottom the pagination is gone to 10......my question is how i can restrict the pagination along with the data

        if(!empty($searchData) || !empty($searchName))
      case "search_data":{
                            //code here
          //code for pagination for example 3 pages is created in this condition
            }
            break;
            case "search_name":
            {
                //code here
                 //code for pagination for example 2 pages is created in this condition
            }
            break;
        }

    else
    {
        //code here
         //code for pagination for example 10 pages is created in this condition
    }
    }
    <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
        <button type="submit value="search_data">Search Data</button>
        <button type="submit value="search_name">Search Name</button>
    </form>
