我使用mpdf类生成pdf。数据的第一行已生成。
<?php
$host="localhost";
$db_user="root";
$db_password="";
$dbname="test";
$connect=mysql_connect($host,$db_user,$db_password) or die(mysql_error());
$select_db=mysql_select_db($dbname);
require_once('mpdf.php');
ob_start();
?>

为什么我的pdf只生成第一行。我找不到错误。如何正确获取pdf
答案 0 :(得分：1)
首先，我不知道您为什么使用此行array_push($resultData,$data);，因为您未在提供的任何代码中使用它。
然后，您遇到的第二个问题是您正在对不存在的数组使用echo，这可能就是为什么您只得到第一行的原因，我相信这是标题。
所以请更改这些行：
<tr>
<td align="right" class="style3"><?php echo $result['$i'];?></td>
<td align="right" class="style3"><?php echo $result['batch'];?></td>
<td align="right" class="style3"><?php echo $result['center']; ?>
<td align="right" class="style3"><?php echo $result['code']; ?></td>
<td align="right" class="style3"><?php echo $result['created_at']; ?></td>
</tr>
到
<tr>
<td align="right" class="style3"><?php echo $data['$i'];?></td>
<td align="right" class="style3"><?php echo $data['batch'];?></td>
<td align="right" class="style3"><?php echo $data['center']; ?> </td>
<td align="right" class="style3"><?php echo $data['code']; ?></td>
<td align="right" class="style3"><?php echo $data['created_at']; ?></td>
</tr>
我想你应该没问题。 更新： 至于在每页上显示页眉，这是一种解决方案，它通过设置一个计数器并每次递增计数器来工作，一旦计数器达到50（或每页最大行数-由您设置），它将打印页眉再次。 这是代码：
<?php $linesPerPageCount =0;
while($data = mysql_fetch_array($objQuery)){
?>
<?php if($linesPerCount == 50){
$linesPerCount = 0;
?>
<tr align="center">
<td width="44" height="23" align="center" bgcolor="#D5D5D5"><strong>aaa</strong></td>
<td width="44" height="23" align="center" bgcolor="#D5D5D5"><strong>bbbb</strong></td>
<td width="178" align="center" bgcolor="#D5D5D5"><strong>bbbbb</strong></td>
<td width="123" align="center" bgcolor="#D5D5D5"><strong>vvvvvvvvv</strong></td>
<td width="123" align="center" bgcolor="#D5D5D5"><strong>vvvvvvvvv</strong></td>
</tr>
<?php
}
<tr>
<td align="right" class="style3"><?php echo $result['$i'];?></td>
<td align="right" class="style3"><?php echo $result['batch'];?></td>
<td align="right" class="style3"><?php echo $result['center']; ?>
<td align="right" class="style3"><?php echo $result['code']; ?></td>
<td align="right" class="style3"><?php echo $result['created_at']; ?></td>
</tr>
<?php $linesPerCount++; } ?>
