限制讀取結果的頁面

-4

此文件包含在我的索引文件中，我不想超過5個帖子在頁面和帖子下1 2 3 4 ...等等（下一頁的鏈接），它看起來像這樣index.php？page = 2 對不起，我的語法錯誤。限制讀取結果的頁面

<?php 
    if(isset($_GET['post_edit'])) { 
    $p_id = $_GET['post_edit']; 

    $p_query = mysql_query("SELECT title, post FROM posts WHERE id='$p_id'"); 
    $p_array = mysql_fetch_array($p_query); 
    $title = $p_array['title']; 
    $post = $p_array['post']; 
    } 
    ?> 

    <?php 
    if(isset($_POST['edit'])){ 
     $title_edit = $_POST['titleedit']; 
     $post_edit = $_POST['postedit']; 

    if(empty($title) or empty($post)){ 
     echo "<p>Fields empty!</p>"; 
     } else { 
     mysql_query("UPDATE posts SET title='$title_edit', post='$post_edit' WHERE id='$p_id'"); 
     echo "Edit succesful!</br>";

您是否在尋找php分頁腳本？ – cartina

這就是所謂的「分頁」，我上次計算的時候有三個gajillion教程。 – deceze

http://stackoverflow.com/questions/11917775/truncate-number-of-pages-in-pagination – Adam

SELECT * FROM TABLE_NAME LIMIT N，M

其中N - 有限行和M（偏移）的數目= N *（PAGE -1）

明白了。但現在我怎麼得到所有其他結果顯示在下一頁像這樣 - index.php？page = 2我應該做另一個isset？我需要寫什麼？ – user2637523

您應該使用LIMIT子句中你的MySQL查詢，請參閱the docs

爲了計算numbe射速頁面，還需要行的總數，這可以使用SQL_CALC_FOUND_ROWS發現，看the docs或this question
