Question

我正在实施一个管理员有权维护库存的网站。我在html表中显示数据库中的库存。我使用分页来显示每页10条记录。我希望当我在第1页时显示＆＃34;显示总记录的1-10，＃34;当我在第2页时显示＆＃34;显示总记录的11-20和＃34;反之亦然。代码：

<?php          
                $link = mysql_connect("localhost", "root", "");
                mysql_select_db("login", $link);    
                $result = mysql_query("SELECT COUNT(*) FROM add_stock");
                $row = mysql_fetch_row($result);
                $num = $row[0];

                ?>
    <table align="center" border="0" id="myTable" class="table table-striped table-bordered table-list">
            <tr>
              <th>Sr.No</th>
              <th>Product Code</th>
              <th>Brand</th>
              <th>Price</th>
              <th>Gender</th>
              <th>Category</th>
              <th>Material</th>
              <th>Size</th>
              <th>Description</th>
              <th>Quantity</th>
              <th><b>Image</b></th>
              </tr> 
    $num_rec_per_page=10;

                    if (isset($_GET["page"])) { $page  = $_GET["page"]; } else { $page=1; }; 
                    $start_from = ($page-1) * $num_rec_per_page; 
                    $sql = "SELECT * FROM add_stock  ORDER BY id DESC LIMIT $start_from, $num_rec_per_page"; 
                    $rs_result = mysql_query ($sql); //run the query
                    $total_records = mysql_num_rows($rs_result);  //count number of records
                    $total_pages = ceil($total_records / $num_rec_per_page); 

                    $next_page = $page + 1;
                    $prev_page = $page - 1;
                     $i= $start_from;
                     $start=1;
                    while ($result=mysql_fetch_array($rs_result) )
                    {                
                    ?>
                    <tr>
                    <td><?php echo $i+$start; ?></td>
                    <td><?php echo $result['id']; ?></td>
                    <td><?php echo $result['brand_name']; ?></td>

                    <td><?php echo $result['dress_description']; ?></td>
                    <td><?php echo $result['dress_quantity']; ?></td>

                    <td><a href="javascript:window.open('<?php echo $result['image'] ?>','mypopuptitle', '_parent')" >View Image</a></td>
                  </tr>

                  <?php
                  $i++; 
                } ?>
                </table>
                 <?php
                    $sql = "SELECT * FROM add_stock"; 
                    $rs_result = mysql_query($sql); //run the query

                    ?> 
                    <div style="margin-left: 5px;">
                    <div class="pagination">
                    <?php
                    echo "<a href='viewstock.php?page=1'><b>&laquo;</b></a>";
                    if ($page==1) {
                    $page=1;
                    }
                    else{
                    echo "<a href='viewstock.php?page=$prev_page'><b>Prev</b></a>"; }
                    for ($i=1; $i<=$total_pages; $i++) {
                    echo "<a href='viewstock.php?page=".$i."'><b>".$i."</b></a>";
                    }
                    if ($page==$total_pages) {
                    $page=$total_pages;
                    }
                    else{
                    echo "<a href='viewstock.php?page=$next_page'><b>Next</b></a>"; }
                    echo "<a href='viewstock.php?page=$total_pages'><b>&raquo;</b></a> ";
                    ?> 
                    </div>
                    </div>

<p>Displaying <?php echo $start ?> - <?php echo $total_records ?>  of Records: <?php echo $num ?></p>

Answer 1

这将有效：

<p>Displaying <?php echo $start_from+1 ?> - <?php echo $start_from + $total_records ?> of Records: <?php echo $num ?></p>

只要你：

1）将输出移动到计算所需数字的代码下方

2）不要在$total_records之后重复使用变量SELECT * FROM add_stock。而是给变量的这个实例赋一个新名称，这样它就不会与早期版本混淆，这意味着你的输出需要不同的东西。

请注意我关于您的SQL注入漏洞的第一条评论，您应该尽快采取措施进行修复。
