非常重要，您鏈接級聯是錯誤的，use & instead of ? again：

<?php 
} 
          $page_sql = mysqli_query($conn, "SELECT * FROM 
`posts` WHERE `p_category` = '$_GET[category]'"); 
          $count_page = mysqli_num_rows($page_sql); 
          $total_page = ceil($count_page/$per_page); /// cail for make value int 

          ?> 
          <nav class="text-center"> 
          <ul class="pagination"> 
          <?php 
          for($i = 1 ; $i <= $total_page; $i++) 
          { 
          echo '<li '.($page==$i ? 'class="active"' : '').' ><a href="category.php?category='.$_GET['category'].'&page='.$i.'">'.$i.'</a></li>'; 
          } 

          ?>
