【问题描述】：
我的拼贴项目即将结束，我现在正在尝试编写一个使用 FPDF 生成 PDF 文件的脚本。
该脚本应查询数据表并从一个表返回作业数据并从另一表返回作业 cmets。这一切都有效。
然后我以每页最多 25 行的行输出每个作业（横向）。同样，所有这些都有效。输出所有作业后，我需要在作业数据下方输出 cmets 数据。
这可行，但 cmets 数据不会在页面底部之前分页。任何人都可以看到我哪里出错了。我在我认为错误的地方用 //***** 标记了下面的脚本。我知道脚本很长，但我认为它可以更好地解释我的问题。

【问题讨论】：
-
$pdf->AddPage(L);L应该用引号引起来（在代码的顶部）。 -
您需要使用行而不是手动添加单元格。如果启用 $pdf->SetAutoPageBreak。它会自动添加分页符。
