如何在Chrome / FF / IE PHP上強制打開PDF

      $pdf->Output();
   ?>

上面是單擊PRINT按鈕后調用的PHP，我創建的數據通過AJAX從我的輸入字段發送，然后查詢並打印為PDF 。

如何強制打開用FPDF制作的PDF文件？ 每次我單擊PRINT按鈕時，它都隨IDM一起下載，但是當我關閉IDM的瀏覽器集成時，單擊“打印”不會發生任何事情。

Answer 1

將您的最后一行更改為：

$pdf->Output('', 'I');

第一個參數是您要賦予文件的名稱，第二個參數是文件的提供方式。

“我”會將pdf內聯發送到瀏覽器。

其他選項如下

I: send the file inline to the browser (default). The plug-in is used if available. The name given by name is used when one selects the "Save as" option on the link generating the PDF.
D: send to the browser and force a file download with the name given by name.
F: save to a local server file with the name given by name.
S: return the document as a string (name is ignored).
FI: equivalent to F + I option
FD: equivalent to F + D option
E: return the document as base64 mime multi-part email attachment (RFC 2045)
