我想在 PDF 文件中显示结果。现在的问题是 PDF 文件只能捕获 while 循环的第一行。第一行是否有类似 row[0]['rates'] 的内容，第二行是否有类似 row[1]['rates'] 的内容？因此，我只需获取一次并显示 row[0]['rates'] 和 row[1]['rates']...
创建 PDF:
<?php
session_start();
if( empty( $_POST['compare'] ) )
include"connect_to_mysql.php";
$packages = mysql_query("SELECT*FROM package_creation WHERE id IN (". implode(',', $_POST['compare']) ." ) LIMIT 4");
while($row=mysql_fetch_array($packages)){
$compare ='<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Compare Packages</title>
<style type="text/css">
.print_title{

}
.print_text{

}
include_once('dompdf/dompdf_config.inc.php');
$dompdf = new DOMPDF();
$dompdf->load_html($compare);
$dompdf->render();
$dompdf->stream('Compare_Packages.pdf');
?>
最佳答案
问题是你的 while 循环。每次循环时都会覆盖 $compare 的值。你想要做的事情是这样的
$compare = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Compare Packages</title>
<style type="text/css">
....//you styles here
</style>
</head>
<body>
<table class="print_text" align="left">
<tr>
<td width="200px" class="print_bold" align="right">Package</td><td width="100px" class="print_bold" align="center">Package 1</td><td width="100px" class="print_bold" align="center">Package 2</td><td width="100px" class="print_bold" align="center">Package 3</td><td width="100px" class="print_bold" align="center">Package 4</td>
</tr>';
while($row=mysql_fetch_array($packages)){
$compare .= '<tr>
<td class="print_bold" align="right">Bank Code:</td><td width="100px" align="center">'.$row['bank_name'].'</td><td width="100px" align="center">display 2nd bank</td><td width="100px" align="center">display 3rd bank</td><td width="100px" align="center">display 4th bank</td>
</tr>';
} //end while
$compare .= '</table>
</body>
</html>';
//rest of your code
这样，它将循环结果添加到 $compare 字符串的中间，而不是每次都覆盖它。查找字符串连接以了解更多详细信息 http://php.net/manual/en/language.operators.string.php 。由于未经测试，如果这里有任何小代码问题，我们深表歉意
