PHP FPDF 分页符不起作用

Question

我的拼贴项目即将结束，现在我正在尝试编写一个脚本，使用 FPDF 生成 PDF 文件。

脚本应该从一个 table 查询数据 tables 和 return 工作数据，从另一个 table 查询工作评论。所有这些都有效。

然后我按行输出每个作业，每页最多 25 行（横向）。同样，所有这些都有效。输出完所有作业后，我需要输出作业数据下方的评论数据。

这可行，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哪里出错了。我在下面的脚本中标记了 //***** 在我认为错误的地方。我知道脚本很长，但我认为它可以更好地解释我的问题。

$pdf = new PDF();
$pdf->AliasNbPages();

$pdf->AddPage(L);

$y_axis_initial = 40;

//initialize counter
$i = 0;

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

//Set Row Height

$y_axis = $y_axis + $row_height;

Answer 1

首先，你的数据有问题，所以我已经更正了你的数据，解决了你的问题(See result):

<?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"]),
                Array ( "UniqueID" => "NXLHR01071474538755", "SeqID" => "SeqID203", "Comments" => ["Room Door Handle/Strike plate", "Not Secure/Not Working Security Door Chain", "Not Working Room Door Dead Lock", "Not operating Correctly"] ),
                Array ( "UniqueID" => "NXLHR01071474538755", "SeqID" => "SeqID304", "Comments" => ["Unit", "Noisy", "Not Working"] ),
                Array ( "UniqueID" => "NXLHR01071474538755", "SeqID" => "SeqID404", "Comments" => ["Door Hinges", "Squeaks/Sticks", "Requires Oil/Repair"] ),
                Array ( "UniqueID" => "NXLHR01071474538755", "SeqID" => "SeqID502", "Comments" => ["Door Handle/Strike plate", "Not secure/Not Working"] ),
                Array ( "UniqueID" => "NXLHR01071474538755", "SeqID" => "SeqID1411", "Comments" => ["Taps", "Not Secure/Leaking", "Repair Pop Up Stoppers or Plug", "Requires Adjustment Cloths Line", "Damaged/Broken", "Repair Bath Panel", "Damaged", "Repair Poor Cracked Grouting/Sealant/Silicon/Strip", "Repair Shower head", "Aerator de-Scaled"] ),
                Array ( "UniqueID" => "NXLHR01071474538755", "SeqID" => "SeqID1305", "Comments" => ["Stained / Discoloured / Limescale Visible/ Tarnished", "Repair"] )];

$max_comments_per_page = 10;

$pdf->SetFont('Arial','',8);

//echo $row_Comments[0]["Comments"];
$j = 1;
foreach($row_Comments as $row_Comment) {
  foreach($row_Comment["Comments"] as $comment) {

    //echo $j;
    if ($j >= $max_comments_per_page) {
        $j = 1;
        $pdf->AddPage();
        $pdf->Ln(10);
        $pdf->SetFont('Arial','B',16);
        $pdf->Cell(40,10,'Auditors comments');
        $pdf->SetFont('Arial','',8);

    }

    $pdf->Ln(10);
    $pdf->Cell(40,10,$comment);
    $j++;

  }
}

$pdf->Output();
?>

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

防止每页评论一定数量的控制流程大部分是正确的。但是在声明和启动 $max_comments_per_page_ = 25; 时有一个错字，它必须是 $max_comments_per_page = 25;

我已经将一些数字从 $max_comments_per_page = 25; 更改为 $max_comments_per_page = 10;，因为很难看出相关性。我已经删除了 table 设计（MultiCell），因为它与这个问题无关。所以现在 table 设计由您决定。

最终，FPDF 的基本（又名强制）分页功能真正起作用了。问题在于您的数据和您对循环的选择。

Answer 2

启用或禁用自动分页模式我们可以使用SetAutoPageBreak()方法。

SetAutoPageBreak(boolean auto [, float margin])

这里的第二个参数是距页面底部的距离，定义了触发限制。默认情况下，该模式处于打开状态，边距为 2 厘米。

您设置了$pdf->SetAutoPageBreak(false);所以您的页面不能分页

请从脚本中删除这一行，您将得到换行符；

根据问题，它通常发生在 php 程序员身上。我认为 FPDF How to force a page break 这个答案可能对你很有用。你应该尝试一下。上次我使用 fpdf 然后我用数据库创建了一个简单的 pdf。它的工作正常。也像 FPDF 一样，您也可以使用 MPDF 来生成 pdf。尝试链接的答案。谢谢
