在搜索數據庫中插入分頁。 PHP MySQL

我是PHP MySQL的初學者，我有工作和獨立的搜索員工引擎和查看所有員工分頁，但現在我想合併這兩個文件。在搜索數據庫中插入分頁。 PHP MySQL

我想插入分頁功能來搜索我的引擎，但我不知道該怎麼做（儘管它在我看來是所有員工都在工作）。

這裏是我查看全部員工檔案：

<?php 
session_start(); 
include_once 'dbconnect.php'; 

if(!isset($_SESSION['user'])) 
{ header("Location: index.php");} 
$res=mysql_query("SELECT * FROM accounts WHERE user_id=".$_SESSION['user']); 
$userRow=mysql_fetch_array($res); 

$sql = "SELECT * FROM accounts ORDER BY agentLname ASC"; 

if(isset($_SESSION['usertype']) && $_SESSION['usertype'] == 'Admin') { 

?> 

<html> 
<body> 

    <div class="row mt"> 
    <div class="col-md-12"> 
    <div class="content-panel"> 

    <?php 
    if($result = mysql_query($sql)){ 
    if (mysql_num_rows($result) > 0) {

那很多代碼，你能簡化問題/代碼嗎？你也應該在'header（「Location：index.php」）;'之後退出。另外'不工作'是不是太有用，沒有工作如何，錯誤，沒有結果... – chris85

嗨@ chris85，其實我在我的搜索引擎中插入分頁問題。我想在我的搜索引擎中轉換分頁，但我不知道如何。 – Edmhar

請通過這種方式嘗試

<?php 

function pagination($num, $per_page = 3,$page = 1, $url = '?'){   

    $total = $num; 
    $adjacents = "2"; 

    $page = ($page == 0 ? 1 : $page); 
    $start = ($page - 1) * $per_page;        

    $prev = $page - 1;       
    $next = $page + 1; 
    $lastpage = ceil($total/$per_page); 
    $lpm1 = $lastpage - 1; 

    $pagination = ""; 
    if($lastpage > 1) 
    { 
     $pagination .= "<ul class='pagination'>"; 
       $pagination .= "<li class='details'>Page $page of $lastpage</li>"; 
     if ($lastpage < 7 + ($adjacents * 2)) 
     { 
      for ($counter = 1; $counter <= $lastpage; $counter++) 
      { 
       if ($counter == $page) 
        $pagination.= "<li><a class='current'>$counter</a> </li>"; 
       else 
        $pagination.= "<li><a href='{$url}page=$counter'>$counter</a></li>";      
      } 
     } 
     elseif($lastpage > 5 + ($adjacents * 2)) 
     { 
      if($page < 1 + ($adjacents * 2))

       { 
        if ($counter == $page) 
         $pagination.= "<li><a class='current'>$counter</a></li>"; 
        else 
         $pagination.= "<li><a href='{$url}page=$counter'>$counter</a></li>";      
       } 
       $pagination.= "<li class='dot'>..</li>"; 
       $pagination.= "<li><a href='{$url}page=$lpm1'>$lpm1</a></li>"; 
       $pagination.= "<li><a href='{$url}page=$lastpage'>$lastpage</a></li>";

       $pagination.= "<li><a href='{$url}page=2'>2</a></li>"; 
       $pagination.= "<li class='dot'>..</li>"; 
       for ($counter = $lastpage - (2 + ($adjacents * 2)); $counter <= $lastpage; $counter++) 
       { 
        if ($counter == $page) 
         $pagination.= "<li><a class='current'>$counter</a></li>"; 
        else 
         $pagination.= "<li><a href='{$url}page=$counter'>$counter</a></li>";      
       } 
      } 
     } 

     if ($page < $counter - 1){ 
      $pagination.= "<li><a href='{$url}page=$next'>Next</a></li>"; 
      $pagination.= "<li><a href='{$url}page=$lastpage'>Last</a></li>";

     } 
     $pagination.= "</ul>\n";   
    } 


    return $pagination; 
} 
?>

添加此選項如下─

<?php 
define("DB_HOST", "yourhost"); 
define("DB_USER", "DBuser"); 
define("DB_PASSWORD", "passwrod"); 
define("DB_DATABASE", "DB name"); 
$conn = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD,DB_DATABASE); 
?>

或者你可以在這裏使用自己的數據庫連接文件

//設置分頁

$query = "SELECT * FROM accounts WHERE agentFname LIKE '%" . $name . "%' OR agentLname LIKE '%" . $name ."%'"; 
$num = mysqli_num_rows($conn->query($query)); 

$per_page = 3; 
$page = 1; 
$url = 'pagination.php'; 

if(isset($_REQUEST['start'])){ 
    $start = $_REQUEST['start']; 
}else{ 

    $start = '0'; 
} 



$sql = "SELECT * FROM accounts WHERE agentFname LIKE '%" . $name . "%' OR agentLname LIKE '%" . $name ."%' LIMIT $start, $per_page "; 
$result = $conn->query($sql); 

while($row=mysql_fetch_array($result)){ 
    //all info you want to print 
    $aCode = $row['agentCode']; 
     $aFName = $row['agentFname']; 
     . 
     . 
} 

echo pagination($num, $per_page = 3,$page = 1, $url = '?');

謝謝。但我在這方面有問題
注意：未定義變量：conn在C：\ xampp \ htdocs \ CIS \ search.php上線177
致命錯誤：調用成員函數query（）對C：\ xampp \ htdocs \ CIS \ search.php在線177 – Edmhar

我已經修復連接先生，但它似乎有這樣的問題：警告：mysqli_num_rows（）期望參數1是mysqli_result，給出的字符串 – Edmhar

我chage $ num喜歡這個： $ num = mysqli_num_rows（$ query）; – Edmhar
