Question

我正在使用我的脚本分页。但即使是搜索自助餐也很少。由于搜索标准，我的分页也无法正常工作。我希望首先显示所有记录，然后如果根据它显示给定的搜索条件。然后只有我的分页工作。

但我没有得到怎么做

这是我的脚本，用于显示来自数据库的记录

if(isset($_GET['page'])){ $page=$_GET['page']; } else { $page=1; }
$start_page=($page-1)*5;

`$sql="query";

if(isset($_POST['submit']))
{


    $company = $_POST['company'];
    $product = $_POST['product'];


if(isset($_POST['submit']) && ($_POST['company']!='') && ($_POST['product']!=''))
{
$sql= "My query goes here";
}

elseif(isset($_POST['submit']) && ($_POST['company']!=''))
{
$sql= "My query goes here";
}   
elseif(isset($_POST['submit']) && ($_POST['product']!=''))
{
$sql= "My query goes here";
}   

elseif(isset($_POST['submit']))
{
$sql= "My query goes here";

}
}
$sql1 = mysql_query($sql) or die(mysql_error());
//Display
?>
<div class="w-box w-box-blue">
<div class="w-box-header">
   </div>
<div class="w-box-content"> 

    <table id="dt_hScroll" class="table table-striped">

                        <th>Company</th>
                        <th>Reference</th>
                        <th>Total Value</th>
                        <th>Action</th>
                        </tr>
                        </thead>
                        <?php
                        while($row=mysql_fetch_array($sql1))
{

    //Display

    ?>

    // echo forward link for next page

尝试使用某种查询构建器，这将使您的任务更容易。所有流行的框架都有这种工具。为分页构建 count 查询要容易得多。您可以在此处查看http://framework.zend.com/manual/1.12/en/zend.db.select.html
