PHPDesktop and mPDF, print forces to save instead of showing print dialog

[Shobhit Gupta]

I have written code for printing report using mdf library in PHP as below:

include("..\mpdf\mpdf.php");
$mpdf=new mPDF('','A4');
$mpdf->WriteHTML($a);
$mpdf->SetJS('this.print();');
$mpdf->Output();
exit;

When I use this applicaiton, things go fine. I directly get print dialog box and there are no PHP warnings too. But when the same application is executed under PHPDesktop, it shows pdf save dialog instead of showing print dialog

I want to open the print dialog box in PHPDesktop also. Please provide some solution.

I have downloaded phpdesktop-chrome-57.0-rc-php-7.1.3 from Github. Also, I have downloaded php_printer.dll from Github. Version is php_printer-php5.6.30
I have placed the dll in every possible folder and also have added it as
 an extension to the php.ini file of PHPDesktop project directory. Now, 
it tries to show the preview but says: "Failed to load PDF document"

You can replace PHP version in PHP Desktop with one that works with your extension (5.6.30). See:

HI, thnx for your response.
Actually, first I downloaded: phpdesktop-chrome-31.8-php-5.6.1
In this version, it creates the pdf successfully, but the issue is that it asks to save the pdf instead of opening the print dialog box.
Then after going through various articles, I downloaded phpdesktop-chrome-57.0-rc-php-7.1.3
This time, it tries to show a preview but days "Failed to load PDF document"
I also tries to change and apply the extension of php_printer from php-master, but nothing works.

[Shobhit Gupta]

I am not able to figure out the perfect combination.

Please note, in normal web browsers, my project works fine with XAMPP having 5.6.x verion of PHP.

Can you please suggest the right versions of:

PHPDesktop

PHP

php_printer.dll

mPDF

such that when i click on print button,  i get a print dialogue box where I can just select a print and click print button or cancel button.

please help.

Hi.

I have similar error but i don't have the message "Failed to load PDF document"...i have a white screen.

Is there a chromium plugin/dll for pdf viewing?

[Czarek Tomczak]

PHP Desktop v57 supports PDF viewing.

[Shobhit Gupta]

Hi,

If it supports PDF Viewing then why I am getting an error. When things are working fine in Chrome Web Browser, then why there is an error in PHPDesktop?

[Czarek Tomczak]

Your issue is with an extension that is incompatible with the php version in phpdesktop.

[Shobhit Gupta]

I understand, but ease suggest me the right versioning for my scenario

[Czarek Tomczak]

You have a problem with the extension, thus your problem is not suitable for this forum. Unless you can provide information that this is an issue with phpdesktop.

[Shobhit Gupta]

Hi, finally I got it working. Updating mPDF and minor changes in code made things work but now I have another issue, on creating setup with innodbwith the steps suggested on PHPOcean, when I run the application after installing it, I see only white screen and error says file not found. While things worked fine in php-desktop

[Czarek Tomczak]

Compare your phpdesktop directory with the program files installation directory and see which files/directories are missing. Probably you have not configured inno setup properly to include all necessary files.

[enrico.m...@gmail.com]

for the "file not found" issue:

in my installation I have to add

extension=php_mbstring.dll

in my php.ini inside PhpDesktop folder /php/
(only tested in phpdesktop-chrome-57.0-rc-php-7.1.3 + mPDF 7.1.1 )

hope this help.
