PHP FPDF分页符不起作用

我的拼贴项目结束时我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,并从另一个表返回作业注释.这一切都有效.

然后我按行输出每个作业,每页最多25行(横向).这一切都有效.在输出所有作业之后,我需要在作业数据下面输出注释数据.

这有效,但评论数据不会在页面底部之前分页.任何人都可以看到我出错的地方.在我认为错误的地方,我用//*****标记了下面的脚本.我知道剧本很长但我认为它可以更好地解释我的问题.

$pdf = new PDF();
$pdf->AliasNbPages();
$pdf->SetAutoPageBreak(false);
$pdf->AddPage(L);

$y_axis_initial = 40;

//initialize counter
$i = 0;

//Set maximum rows per page
$max = 25;
$y_axis = 40;

//Set Row Height
$row_height = 6;

$y_axis = $y_axis + $row_height;

$pdf->SetFillColor(232,232,232);
$pdf->SetFont('Arial','B',9);
$pdf->SetY(40);

首先，您的数据有错误，所以我已经更正了您的数据并解决了您的问题（查看结果）：

<?php
require('./fpdf.php');

$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Auditors comments');

$row_Comments = [Array ( "UniqueID" => "NXLHR01071474538755", "SeqID" => "SeqID110", "Comments" => ["Chipped", "Scratched", "Stained", "Needs Paint"]),

$max_comments_per_page = 10;

您需要使用嵌套循环，因为您的数据是嵌套的。您应该使用嵌套的 foreach 循环，而不是使用 while 循环，而不是使用 while 循环。起初，变量名称令人困惑，但后来，我明白了你想要实现的目标。

用于防止每页一定数量评论的控制流程大部分是正确的。但是声明和发起时出现了拼写错误，$max_comments_per_page_ = 25;必须是$max_comments_per_page = 25;

我更改了一些数字，例如从$max_comments_per_page = 25;到$max_comments_per_page = 10;，因为很难看出相关性。我已经删除了表格设计（MultiCell），因为它与这个问题无关。所以桌子的设计现在就由你决定了。

最终，FPDF 的基本（也称为强制）分页功能真正发挥了作用。问题在于你的数据和你对循环的选择。
