PHP分頁問題

Question

我的代碼有問題（非常抱歉，但這是我知道向您顯示的唯一方法，它基本上只是一個表中的select語句），它顯示頁面鏈接，但不會更改頁面結果。 基本上，我將其設置為每頁1個結果，但它顯示了所有結果，但仍在頂部顯示一個鏈接，可轉到下一頁。 下一頁僅顯示相同內容。 我是PHP的初學者，所以任何幫助將不勝感激。

謝謝！

邁克爾，我嘗試了您的操作，但可能做錯了...這是where語句之前的代碼

    <?php
        $page = 1; $total_pages = 9; $record_start = ($page * $total_pages) - $total_pages; 
            REQUIRE('config.php');
            $q = mysql_real_escape_string(ucfirst(trim($_REQUEST['q'])));
            $result = mysql_query("SELECT * FROM gj WHERE name LIKE '%$q%' OR cat1 LIKE '%$q%' OR cat2 LIKE '%$q' OR cat3 LIKE '%$q' ORDER by name  LIMIT 0,9") or trigger_error(mysql_error());
            $rows = mysql_num_rows($result);
            if($rows == 0){

            }
            echo " <div id='title'>Search for &quot;$q&quot;<div class='righttitle'>$rows business";if($rows > 1){echo "es";}elseif($rows == "0"){echo "es";}echo" found";

Answer 1

問題在於，無論哪個頁面當前處於“活動”狀態，您總是會獲取相同的結果集，然后僅輸出所有結果集。 如果要分頁，則可能要在SQL查詢中使用LIMIT子句（例如LIMIT 20,10從偏移量20（從零開始，即記錄編號21））返回10條記錄。

Answer 2

您需要做的是添加如下內容：

$ page = 1;

$ results_per_page = 10;

$ record_start =（$ page * $ results_per_page）-$ results_per_page;

$ result = mysql_query（“ SELECT * FROM gj，其中名稱類似'％$ q％'或cat1類似'％$ q％'或cat2類似'％$ q'或cat3類似'％$ q'的名稱按名稱LIMIT $ record_start ，$ results_per_page“）或trigger_error（mysql_error（））;
