使用以下ajax代码我将变量'a'发送到php文件get_output.php:
var a="";
for($i=0;$i<n;$i=$i+1)
{
var a = (a+'. '+ (document.getElementById((values[$i])).innerHTML));
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("output_container").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("POST","get_output.php?q="+a,true);
xmlhttp.send();
在get_output.php中,存在以下代码:
<html>
<head>
</head>
<body>
<?php
$value=$_GET["q"];
echo $value;
?>
</body>
</html>
这里我得到了我想要的变量'value'。 现在我想将变量'value'内容放入pdf文件中。当我在谷歌研究时发现所有解决方案都是通过使用'url'等将整个页面变成pdf文件。
我想要的是变量'value'中的内容应该是PDF文件。谢谢。

您可以使用TCPDF执行此操作。TCPDF
是用于生成PDF文档的PHP类。Download it,并修改TCPDF / pdfgenerator / examples /中的$html
变量example_001.php文件为:
// Set some content to print
$html = <<<EOD
<div>
$value
</div>
EOD;
或者在test.php
文件夹中创建一个新文件(比如/TCPDF/pdfgenerator/examples/
)。将以下代码粘贴到您刚刚创建的新文件中:
<?php
require_once('../config/lang/eng.php');
require_once('../tcpdf.php');
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$value=$_GET["q"];/*The value that you want to print*/
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 001');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, '','', array(0,64,255), array(0,64,128));
$pdf->setFooterData($tc=array(0,64,0), $lc=array(0,64,128));
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
//set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
//set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
//set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
//set some language-dependent strings
$pdf->setLanguageArray($l);
// set default font subsetting mode
$pdf->setFontSubsetting(true);
// Set font
// dejavusans is a UTF-8 Unicode font, if you only need to
// print standard ASCII chars, you can use core fonts like
// helvetica or times to reduce file size.
$pdf->SetFont('times', '', 11, '', true);
// Add a page
// This method has several options, check the source code documentation for more information.
$pdf->AddPage();
// set text shadow effect
$pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));
// Set some content to print
$html = <<<EOD
<div>
$value
</div>
EOD;
// Print text using writeHTMLCell()
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $html, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=true);
// ---------------------------------------------------------
// Close and output PDF document
// This method has several options, check the source code documentation for more information.
$pdf->Output("generatedpdf.pdf", 'F');
//============================================================+
// END OF FILE
//============================================================+
?>
运行时,TCPDF/pdfgenerator/examples/generatedpdf.pdf
会生成一个新的pdf文件
它只包含$value
php变量中的值。

答案 2 :(得分:0)
这里我发送代码以便从主页获取值到PDF页面,如果id相同
$id = intval($_GET['id']);
// Make sure the ID is in fact a valid ID
if($id <= 0)
{
die('The ID is invalid!');
}
else
{
require("fpdf.php");
$pdf=new FPDF();
//var_dump(get_class_methods($pdf));
$pdf->AddPage();
//------------------------
$pdf->SetFont("arial","B","20");
$pdf->Cell(160,10,"t",1,0,"l");
$pdf->Cell(30,10,"".$t,1,1,"l");
$pdf->Output();
}
} //top most close
else
{
echo 'Error! No ID was passed.';
}
?>
//PDF code
}
