Question

伙计们，我在这里需要有关此代码的帮助..这是一个计数器代码..它工作正常，但不是我想要的工作方式。问题是当我编写另一个代码时，我简单地更改了页面名称，但问题是，假设第一页达到了10个视图，第二页将低于10，而它不会超过10。我尝试更改ON DUPLICATE KEY UPDATE，但是我没有得到我需要的结果，请帮助下面的代码...

<?php

function visitor($record) {

      $db_host = "localhost";
      $db_username = "username"; 
      $db_password = "password";
      $db_name = "database-name";
      $db_table = "table-name";
      $counter_page = "access_page";
      $counter_field = "access_counter";

      $db = mysqli_connect ($db_host, $db_username, 
      $db_password, $db_name) or die("Host or database not 
       accessible");

      $sql_call = "INSERT INTO ".$db_table." 
      (".$counter_page.", 
      ".$counter_field.") VALUES ('".$record."', 1) ON 
      DUPLICATE 
      KEY UPDATE ".$counter_field." = ".$counter_field." + 1"; 

     mysqli_query($db, $sql_call) or die("Error while 
     entering");

     $sql_call = "SELECT ".$counter_field. " FROM 
     ".$db_table." 
     WHERE ".$counter_page. " = '".$record. "'";

     $sql_result = mysqli_query($db, $sql_call) or die("SQL 
      request failed ");

    $row = mysqli_fetch_assoc($sql_result);
    $x = $row[$counter_field];

     mysqli_close($db);
     return $x;
   }
?>

<?php 
   $page_name = "pictures";

   $access_number = visitor($page_name);

   echo $access_number;

?>
