Insert images files in existing PDF file using PHP
提问by 125369
My need is that I upload two image files and that should be added to an existing PDF file. I have read about FPDF, basing on that I have followed this post link. In case if somebody can post a simple working example/link it would be helpful for searchers like me and some more people who would also take the same route to find some helpful answers.
我需要上传两个图像文件，并将其添加到现有的 PDF 文件中。我已经阅读了关于 FPDF 的内容，基于我已经关注了这个帖子链接。如果有人可以发布一个简单的工作示例/链接，这对像我这样的搜索者以及更多也会采取相同途径找到一些有用答案的人会有所帮助。

It seems there is an extension called FPDIfor FPDF. Here is a blog post about how to modify an existing pdf: http://pranavom.wordpress.com/2011/03/15/modify-pdf-using-fpdffpdi-library/
似乎有一个名为FPDIfor FPDF的扩展名。这是一篇关于如何修改现有 pdf 的博客文章：http: //pranavom.wordpress.com/2011/03/15/modify-pdf-using-fpdffpdi-library/
You can place an image using FPDI like so:
您可以使用 FPDI 放置图像，如下所示：
$pdf = new FPDI();
$pdf->AddPage();
$pdf->setSourceFile("MySource");
$template = $pdf->importPage(1);
$pdf->useTemplate($template);
$pdf->Image('MyImage.jpg', $x, $y, $width, $height);
$pdf->Output($outputPath, "F");

I am using PHP, FPDF to generate a pdf from an FDF file and then insert a qrcode graphic into the pdf as well. I kept running into trouble because my empty pdf has form fields built in and inserting a graphic with other programs erased my form fields. I finally figured it out. Hope this helps someone else who is struggling with the same.
我正在使用 PHP、FPDF 从 FDF 文件生成 pdf，然后也将 qrcode 图形插入到 pdf 中。我一直遇到麻烦，因为我的空 pdf 有内置的表单域，并用其他程序插入图形删除了我的表单域。我终于弄明白了。希望这可以帮助其他正在苦苦挣扎的人。
