検索ボタンをクリックし、同じページに結果を印刷した後、検索クエリボックスとアルファベット検索の両方を保持する方法

Question

私はクエリフィールドとアルファベット検索を検索したPHPページを作成しました。クエリを送信した後、同じページに結果を印刷します。クエリは正常に動作していますが、結果がアルファベット順の検索結果と同じ場所に表示されます。私。アルファベット順の検索は、結果が検索ボックスから来た後に消えています。どのように私は両方のウェブページを保持することができますか？

     $alpha = $_GET['query']; 
     $min_length = 3; 
     if(strlen($alpha) >= $min_length){ // if query length is more or equal minimum length then 

      $alpha = htmlspecialchars($alpha); 
      // changes characters used in html to their equivalents, for example: < to &gt; 

      $alpha = mysqli_real_escape_string($con, $alpha);
