我想用pdf导出数据。当我选择一个记录,它工作得很好…如何一键创建多个pdf ?这是我尝试的
require_once('eng.php');
require_once('tcpdf.php');
$pageLayout = array(750, 800);
$pdf =new TCPDF('P', 'pt', $pageLayout, true, 'UTF-8', false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->AddPage();
$html = 'my html';
$pdf->writeHTML($html, true, false, true, false, '');
$pdf->lastPage();
$pdf->Output('filename.pdf', 'D');
我怎么能把一个循环创建更多的pdf独立文件?
下面的代码为我工作:
使用变量的变量并在循环中创建新的pdf对象,使用'F'代替'D'保存到服务器
require_once('eng.php');
require_once('tcpdf.php');
$pageLayout = array(750, 800);
$content=Array(
'<html><body>Document A</body></html>',
'<html><body>Document B</body></html>',
'<html><body>Document C</body></html>'
);
foreach($content as $i=>$html){
$pdfname = $pdf . $i;
$$pdfname =new TCPDF('P', 'pt', $pageLayout, true, 'UTF-8', false);
$$pdfname->SetCreator(PDF_CREATOR);
$$pdfname->AddPage();
$$pdfname->writeHTML($html, true, false, true, false, '');
$$pdfname->lastPage();
$$pdfname->Output('filename_' . $i . '.pdf', 'D');
}
试试这个:
require_once('eng.php');
require_once('tcpdf.php');
$pageLayout = array(750, 800);
$content=Array(
'<html><body>Document A</body></html>',
'<html><body>Document B</body></html>',
'<html><body>Document C</body></html>'
);
foreach($content as $i=>$html){
$pdf =new TCPDF('P', 'pt', $pageLayout, true, 'UTF-8', false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->AddPage();
$pdf->writeHTML($html, true, false, true, false, '');
$pdf->lastPage();
$pdf->Output('filename_' . $i . '.pdf', 'D');
}
我已经精炼了答案以匹配我的注释
require_once('eng.php');
require_once('tcpdf.php');
$pageLayout = array(750, 800);
$content=Array(
'<html><body>Document A</body></html>',
'<html><body>Document B</body></html>',
'<html><body>Document C</body></html>'
);
$zip = new ZipArchive();
$filename = "/tmp/final.zip";
$zip->open($filename, ZipArchive::CREATE);
foreach($content as $i=>$html){
$pdf =new TCPDF('P', 'pt', $pageLayout, true, 'UTF-8', false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->AddPage();
$pdf->writeHTML($html, true, false, true, false, '');
$pdf->lastPage();
$pdf->Output('/tmp/filename_' . $i . '.pdf', 'F');
$zip->addFile('/tmp/filename_' . $i . '.pdf','filename_' . $i . '.pdf');
}
$zip->close();
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="final.zip"');
readfile($filename);
答案假设是posix环境下的/tmp目录,这只是一个示例,您应该使用sys_get_temp_dir()来获取临时目录,您还应该在下载后删除文件。
我正在创建一个pdf文档保存在磁盘中,它在循环中也工作得很好。这里我只复制了包含循环
的函数 private function drawBody()
{
foreach($this->ordersList as $store => $storeord){
// to stop the tcpd overwriting the headers and calculating wrong page numbers used $nextstore
$filename = 'Click and Collect List to '.$this->storeID.'-'.$this->storename;
// Master page headers
$this->pdf->SetFont('Arial','B');
$this->pdf->SetFontSize(20);
$this->pdf->SetY(50);
$this->pdf->Cell(0,7,$filename,0,1,'L');
$this->pdf->SetFontSize(8);
$this->pdf->Ln();
$this->pdf->Ln();
$this->pdf->SetFillColor(255,255,255);
$this->pdf->Cell(15,10,'ID',1,0,'C',1,'',1);
$this->pdf->Cell(20,10,'Date ordered',1,0,'C',1,'',1);
$this->pdf->Cell(5,10,'Qty',1,0,'C',1,'',1);
$this->pdf->Cell(15,10,'Customer ID',1,0,'C',1,'',1);
$this->pdf->Cell(30,10,'Name',1,0,'C',1,'',1);
$this->pdf->Cell(25,10,'Mobile',1,0,'C',1,'',1);
$this->pdf->Cell(70,10,'Address',1,0,'C',1,'',1);
$this->pdf->Ln();
// Master page list of orders
foreach($storeord as $ord => $det){
$this->pdf->SetFont('Arial');
$this->pdf->SetFillColor(255,255,255);
$this->pdf->SetFontSize(8);
$this->pdf->Cell(15,10,''. $ord,1,0,'L',1);
$this->pdf->Cell(20,10,''. $det[orderdate],1,0,'L',1);
$this->pdf->Cell(05,10,''. $det[qty],1,0,'L',1);
$this->pdf->Cell(15,10,''. $det[custID],1,0,'L',1);
$this->pdf->Cell(30,10,''. $det[custName],1,0,'L',1);
$this->pdf->Cell(25,10,''. $det[mobile],1,0,'L',1);
$this->pdf->MultiCell(70,10,''. $det[address],1,'L',false);
}
// Draw Collection page for each store
$this->pdf->AddPage();
$this->drawCollectionPage();
$this->pdf->Output('Click and Collect List to - '.$this->storeID.'-'.$this->storename.'.pdf','F');
}
}
