我想重写我的代码的一部分,显示一个表分页,以便如果有多个X记录显示在单独的页面上。我想用MySQLi重写代码,但我还没有想出使用存储结果函数。如何添加分页?

如何使用下面的分页代码修复错误?并使用MYSQLi,因为我当前代码中的四个函数已被弃用

这是旧的代码,只是显示一个工作表。

<?php 

    $username = "some username"; 
    $password = "some password"; 
    $hostname = "localhost"; 
    $databasename = "some database"; 

    //connection to the database 
     $dbhandle = mysql_connect($hostname, $username, $password) 
     or die("Unable to connect to MySQL"); 
     @mysqli_select_db($databasename,$dbhandle); 

    //select a database to work with 
     $selected = mysql_select_db("mydeos_calendar",$dbhandle) 
     or die("Could not select mydeos_calendar"); 

    //execute the SQL query and return records 
     $result = mysql_query("SELECT * FROM appointments "); 
     $num=mysql_numrows($result); 

    mysql_close(); 

    echo"<br><b><center>All Appointments</center></b><br><br>"; 

    // see if any rows were returned 
     if (mysql_num_rows($result) > 0) { 

    // print them one after another 
     echo "<table cellpadding=10 cellspacing=3 border=1 class=sortable>"; 
     echo "<tr><th>Date/Time</th><th>LEP</th> <th>Language</th> <th>Insurance</th><th>Nature</th><th>Duration</th><th>With</th><th>Vendor</th><th>Status</th><th>Appointment Type</th><th>Actions</th></tr>"; 
      while($row = mysql_fetch_row($result)) { 
    require "appointmentrows.php"; 

     echo '<td><a href="something">Edit</a>&nbsp;|&nbsp;<a href="something">Delete</a></td>'; 
     echo "</tr>"; } 
      echo "</table>"; } 
     else { 

    // print status message 
    echo "No Appointments Found!"; 
    } 

    $i=0; 
    while ($i < $num) { 

    $appointment=mysql_result($result,$i,"appointment"); 
    $nature=mysql_result($result,$i,"nature"); 
    $duration=mysql_result($result,$i,"duration"); 
    $status=mysql_result($result,$i,"status"); 
    $language=mysql_result($result,$i,"language"); 
    $lep=mysql_result($result,$i,"lep"); 
    $vendor=mysql_result($result,$i,"vendor"); 
    $insurance=mysql_result($result,$i,"insurance"); 
    $client=mysql_result($result,$i,"client"); 
    $invoiceformat=mysql_result($result,$i,"invoiceformat"); 
    $appointmenttype=mysql_result($result,$i,"appointmenttype"); 
    $i++; 
    } 

?> 

这是新的代码与分页,但我没有得到和结果,看到没有任命找到!和以下错误。

一次处理问题1。 MySQL到MySQLi(过程式)非常相似,尽管一些函数需要你的db连接作为第一个参数。

首先尝试一个简单的例子来获得MySQLi函数工作:

$dbhandle = mysqli_connect($hostname, $username, $password); 
mysqli_select_db($databasename,$dbhandle); 

$sql = "SELECT * FROM $tbl_name"; 
$query = mysqli_query($dbhandle,$sql); 
$pages = mysqli_fetch_array($query); 
$total = mysqli_num_rows($query); 
+0

我知道该怎么做的连接,查询和获取数组,但我从来没有得到过NUM行功能工作和显示器结果。我也想出了当前代码中导致错误的原因,但分页不显示。 –

那不是MySQLi .. ..thats PDO – MaggsWeb

我可以推荐使用PDO,它更强大;-) – N07070

所以我可以.. ..但这不是问题或要求的帮助。 – MaggsWeb
