在PHP中显示带有分页的搜索结果

Question

如何使我的搜索从一个班级开始……我可以在主要页面上显示搜索结果，但我希望它显示所有结果，如果该结果超出分页结果，则客户可以轻松地移至另一页

    <?php 
        // if it's going to need the database, then it's
        //probably smart to require it before we start.
        @require_once(LIB_PATH.DS.'database.php');

        class Product extends DatabaseObject {
            protected static $table_name="products";
            protected static $db_fields=array('id', 'product_id', 'image', 'title', 'slug', 'description', 'price');

            public $id;
            public $product_id;
            public $image;
            public $title;
            public $slug;
            public $description;
            public $price;

        public static function search(){
                global $database;
                $sql  = "SELECT * FROM products WHERE image LIKE '{%$search%'";
                $sql .= " OR title LIKE '{%$search%}'";
                $sql .= " OR slug LIKE '%$search%'";
                $sql .= " OR description LIKE '%$search%'";
                $sql .= " OR price LIKE '%$search%'";
                $total_count = count($sql);
                $result_set = $database->query($total_count);
                $row = $database->fetch_assoc($result_set);
                return array_shift($row);
            }

        ?>

请检查我的代码...我有点困惑。

<?php if(empty($_POST['search'])){

        $page = !empty($_GET['page']) ? (int)$_GET['page'] : 1;
        // 2. records per page ($per_page)
        $per_page = 10;
        // 3. total record count ($total_count)
        //$total_count = Product::count_all();
        $total_count = Product::search();
        // Find all photos
        // use pagination instead
        $pagination = new Pagination($page, $per_page, $total_count);
        // Instead of finding all records, just find the records 

        $search = $database->escape_value($_POST['search']);
//      $sql  = "SELECT * FROM products WHERE image LIKE '%$search%'";
