Question

这是代码search.php - 此代码组合了来自数据库的搜索数据和分页无法正常工作。

<?php include_once('include/header.php'); ?>
<?php
//Declaration
$search_term = '';
$search_results = false;

require 'include/db.php';

//Check if search data was submitted
if (isset($_GET['pages'])) {
// Include the search class
require_once( dirname(__FILE__) . '/class-search.php' );

// Instantiate a new instance of the search class
$search = new search();

// Store search term into a variable
$search_term = $_GET['pages'];

// Send the search term to our search class and store the result
$search_results = $search->search($search_term);
}
?>

这是代码类-search.php

    $start = null;
    $perpage = null;
    class search {

      private $mysqli;


      public function __construct() {
        // Connect to our database and store in $mysqli property
        $this->connect();
      }

      private function connect() {
        $this->mysqli = new mysqli( 'localhost', 'root', 'root', 'fimos' );
      }


      public function search($search_term) {
        // Sanitize the search term to prevent injection attacks
        $sanitized = $this->mysqli->real_escape_string($search_term);


        // Run the query
        $query = $this->mysqli->query("
          SELECT *
          FROM customer_info
          WHERE cust_name LIKE '%{$sanitized}%'
          OR cust_ic LIKE '%{$sanitized}%' {$start} , {$perpage} 
        ");

        // Check results
        if ( ! $query->num_rows ) {
          return false;
        }

        // Loop and fetch objects
        while( $row = $query->fetch_object() ) {
          $rows[] = $row;

        }

        // Build our return result
        $search_results = array(
          'count' => $query->num_rows,
          'results' => $rows,
        );

        return $search_results;
      }
    }

为什么我仍然无法显示2个数据/页面？我点击分页功能1,2,3也同样记录，对我来说搜索页面1也改为结果只有1。我使用类进行搜索功能。希望可以帮助我。
