如何將分頁添加到搜索結果中？

Question

我想在此搜索引擎中添加分頁。這是我曾嘗試：

//get date 
$button = $_GET['submit']; 
$search = $_GET['search']; 

if (!$button) 
    echo "Please fill out the form"; 
else 
{ 
    if (strlen($search)<=2) 
     echo "The item you searched for was to small"; 
    else 
    { 
     echo "You searched for <b>$search</b> <hr size='1'>"; 

    //connect to database 

    mysql_connect('localhost','wnumber','passowrd'); 
    mysql_select_db('wnumber'); 


    //explode search term 
    $search_exploded = explode(" ",$search); 
    foreach($search_exploded as $search_each) 
    { 
     $str = mysql_real_escape_string(substr($search_each, 0, 4)); 
     //construct query 
     $x++; 
     if ($x==1) $construct .= "keywords LIKE '$str%'"; 
     else  $construct .= " OR keywords LIKE '$str%'"; 
    } 

    //echo out construct 
    $construct = "SELECT * FROM word WHERE $construct order by LENGTH(`keywords`)"; 
    $run = mysql_query($construct); 
    $foundnum = mysql_num_rows($run); 

    if ($foundnum==0) 
     echo "No results found."; 
    else 
    { 
     echo "$foundnum results found.<p><hr size='1'>"; 
     while ($runrows = mysql_fetch_assoc($run)) 
     { 

      //get data 
      $meaning = $runrows['meaning']; 
      $keywords = $runrows['keywords']; 

      echo "<b>$keywords</b><br> 
      <b>$meaning</b><br> 
     } 
    } 
    } 

}

看看這個例子，這是你如何可以使分頁與MySQL。

的第一個參數是開始行，第二個是結果的數量來顯示

mysql> select * From t1 limit 0,5; 
+----------+------------+--------------+---------------------+ 
| actor_id | first_name | last_name | last_update   | 
+----------+------------+--------------+---------------------+

|  5 | JOHNNY  | LOLLOBRIGIDA | 2006-02-15 04:34:33 | 
+----------+------------+--------------+---------------------+ 
5 rows in set (0.00 sec)

Answer 2

對於分頁，你應該使用SELECT查詢的LIMIT部分。在這裏閱讀文檔：

http://dev.mysql.com/doc/refman/5.0/en/select.html

例如，如果你想每頁有20個項目，並要到第3頁，你應該只是你的「$運行=請求mysql_query（$構造）之前添加以下行; 「：

$construct = $construct . " LIMIT 60, 20" 

在這種情況下，你跳過了前60條記錄，並選擇未來20

UPDATE：

對於HTML標記，你可以有這樣的：

<div id="paginator"> 
    <ul> 
    <li><a href="page.php?submit=true&search=text_to_search&page=1>1</a></li> 
    <li><a href="page.php?submit=true&search=text_to_search&page=2>2</a></li> 
    etc. 
    </ul> 
</div> 

那麼你的$按鈕後，添加以下行= $ _GET [ '按鈕']開頭：

$page = (!empty($_GET['page'])) ? ((int)$_GET['page']) : (1); 

，改變我行從上面到：

$construct = $construct . " LIMIT {($page-1)*20}, 20" 

這應該是訣竅。

可以使用JavaScript庫來顯示分頁。 http://datatables.net

你可以將你的php結果送到這個庫來創建分頁。
