Fpdf 在数据行到达第一页末尾时添加另一页


Fpdf add another page when data rows reach the end of first page

我正在尝试编写一个使用FPDF生成PDF文档的PHP脚本。到目前为止,我能够生成PDF,但前提是从MySQL查询返回的行数小于页面高度。

如果返回的行数大于第一页可以容纳的剩余行跳转到第二页,但数据到处都是,列没有对齐,并且随着要生成的每一页,它们接缝到阶梯。

我知道我需要放置某种行/行计数,

如果达到行/行计数,请开始一个新页面,但在这里,即使阅读了许多关于如何完成的帖子和文档,我的知识也完全空白。

我拥有的代码是:

class PDF extends FPDF
{
// Page footer
function Footer()
{
    // Position at 1.5 cm from bottom
    $this->SetY(-15);
    // Arial italic 8
    $this->SetFont('Arial','I',8);
    // Page number
    $this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
}
$pdf=new FPDF();
$pdf->AliasNbPages();
$pdf->AddPage('L');
$pdf->SetFont('Arial', 'B', 18);
$pdf->Text(230, 18, 'iMaint');
$pdf->SetFont('Arial', 'B', 18);
$pdf->Text(250, 18, 'Jobsheet');
$pdf->SetY(28);
$pdf->SetX(10);
$pdf->SetFont('Arial', '', 11);
$pdf->Text(10, 28, 'Jobsheet date:');
$pdf->SetY(8);
$pdf->SetX(37); 
$pdf->SetFont('Arial', '', 11);
$pdf->cell(10,38, $ToDay);
$pdf->SetY(13);
$pdf->SetX(10); 
$pdf->SetFont('Arial', '', 11);
$pdf->cell(10,38, 'Audit date:');
$pdf->SetY(13);
$pdf->SetX(37); 
$pdf->SetFont('Arial', '', 11);
$pdf->cell(10,38, date("d-m-Y", strtotime($row_RoomAudit['CompStamp'])));
$pdf->SetFont('Arial', '', 12);
$pdf->Text(240.5, 28, 'Hotel ID:');
$pdf->SetY(10);
$pdf->SetX(183.2);
$pdf->SetFont('Arial', 'B', 18);
$pdf->Text(10, 18, 'Room:');
$pdf->SetFont('Arial', '', 12);
$pdf->SetY(23);
$pdf->SetX(260);    
$pdf->cell(14,8, $_SESSION['hotel']);
$pdf->SetY(12);
$pdf->SetX(30);
$pdf->SetFont('Arial', 'B', 18);
$pdf->cell(14,8, $row_RoomAudit['Room']);
$pdf->Ln(10);
//Fields Name position
$Y_Fields_Name_position = 40;
//Table position, under Fields Name
$Y_Table_Position = 46;
$pdf->SetFillColor(232,232,232);
$pdf->SetFont('Arial','B',11);
$pdf->SetY($Y_Fields_Name_position);
$pdf->SetX(10);
$pdf->Cell(32,6,'Seq',1,0,'L',1);
$pdf->SetX(32);
$pdf->Cell(130,6,'Item',1,0,'L',1);
$pdf->SetX(130);
$pdf->Cell(155,6,'Job description',1,0,'L',1);
$pdf->Ln();
//Initialize the 3 columns and the total
$column_seq = "";
$column_seq_header = "";
$column_job_description = "";
$column_completed = "";
$column_engineer = "";
foreach ($row_RoomAudit as $key => $val) {
     if (strpos($val, '1') !== FALSE && substr( $key, 0, 3)=='Seq' ){
         mysql_select_db($database_iMaint, $iMaint);
        $query_QuestionLookup = sprintf("SELECT SeqHeader, SeqText FROM SequenceNo WHERE SeqID = '".$key."'");
        $QuestionLookup = mysql_query($query_QuestionLookup, $iMaint) or die(mysql_error());
        $row_QuestionLookup = mysql_fetch_assoc($QuestionLookup);
        $totalRows_QuestionLookup = mysql_num_rows($QuestionLookup);
        $seq = $key;
        $Seq_header = $row_QuestionLookup['SeqHeader'];
        $jobdescription = $row_QuestionLookup['SeqText'];
        $column_seq = $column_seq.$seq."'n";
        $column_seq_header = $column_seq_header.$Seq_header."'n";
        $column_job_description =   $column_job_description.$jobdescription."'n";
        $pdf->SetFont('Arial','',8);
        $pdf->SetY($Y_Table_Position);
        $pdf->SetX(10);
        $pdf->MultiCell(22,6,$column_seq,1);
        $pdf->SetY($Y_Table_Position);
        $pdf->SetX(32);
        $pdf->MultiCell(98,6,$column_seq_header,1);
        $pdf->SetY($Y_Table_Position);
        $pdf->SetX(130);
        $pdf->MultiCell(155,6,$column_job_description,1);
    }
}

$i = 0;
$pdf->SetY($Y_Table_Position);
while ($i < $totalRows_RoomAudit)
{
$pdf->SetX(10);
$pdf->MultiCell(184,6,'',1);
$i = $i +1;
}
$pdf->Output();

任何人都可以为我提供一些帮助,不知道如何处理在第二页或第三页上显示剩余的数据等等。

提前感谢您的时间。

干杯。

添加每页的最大记录数 为了确保每页显示记录有限制,这是您需要添加的代码

`$column_completed = "";
$column_engineer = "";
$max_per_page = 15; // adjust for your max per page this mean 16 record per page
$counter_rec = 0;
......`

当计数器超过每页最大记录数时创建新页面

if (strpos($val, '1') !== FALSE && substr( $key, 0, 3)=='Seq' ){ if ($counter_rec > 0 && $counter_rec % 15 == 0){ $pdf->AddPage('L'); // rewrite header for next page here } ......

之后,您需要确保$counter_rec始终计数

希望能有所帮助
