Question

我在拼贴项目结束时，我正在尝试编写一个使用FPDF生成PDF文件的脚本。

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。

这样可行，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();

Answer 1

首先，您的数据有问题，因此我更正了您的数据并解决了您的问题（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，变量名称令人困惑，但后来我明白了你想要实现的目标。

每页阻止一定数量评论的控制流程大多是正确的。但是声明和启动$max_comments_per_page_ = 25;时出现了错字，必须是$max_comments_per_page = 25;

我已将某些数字更改为$max_comments_per_page = 25;到$max_comments_per_page = 10;，因为很难看到相关性。我已经删除了表格设计（MultiCell），因为这个问题与主题无关。所以桌子设计由你决定。

最终，FPDF的基本（又称强制）分页功能实际上正在运行。问题是你的数据和你选择的循环。

Answer 2

要启用或停用自动分页模式，我们可以使用 SetAutoPageBreak() 方法。

SetAutoPageBreak(boolean auto [, float margin])

此处第二个参数是距页面底部的距离，该距离定义了触发限制。默认情况下，模式打开，边距为2厘米。

您已设置$pdf->SetAutoPageBreak(false);因此您无法在页面中获得分页符。

请从脚本中删除此行，您将获得换行符;

Answer 3

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这个问题可能对你非常有用。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。它的工作很好。也像FPDF一样，您也可以使用MPDF生成pdf。尝试使用链接的答案。感谢

PHP FPDF分页符不起作用
