Hi,

I just installed the "export" package and phantomjs, but I am getting the following error message:

Fatal error: Uncaught exception 'Exception' with message 'Could not execute phantomjs' in C:\Users\gven\vqr\vqr-development\www\vendor\koolphp\koolreport\koolreport\packages\export\Handler.php:71 Stack trace: #0 C:\Users\gven\vqr\vqr-development\www\vendor\koolphp\koolreport\koolreport\packages\export\Handler.php(156): koolreport\export\Handler->runPhantom('C:\\Users\\gven\\v...', 'C:\\Users\\gven\\v...', 'C:\\Users\\gven\\v...', 'eyJmb3JtYXQiOiJ...') #1 C:\Users\gven\vqr\vqr-development\www\mypage\index.php(13): koolreport\export\Handler->pdf(Array) #2 {main} thrown in C:\Users\gven\vqr\vqr-development\www\vendor\koolphp\koolreport\koolreport\packages\export\Handler.php on line 71

Looking at line 71, it is an issue with the shell_exec. On my development machine I am running PHP 5.6.36. It is a Windows 10 machine, and the website runs through IIS. I have already assigned an administrator account as the account that runs the website, but this does not make any difference.

The code I am running is just the "mypage.php" example from the package blog. I did have to specify the path to the phantomjs file, because otherwise it gave a not found error. When I did set the path though, that error went away.

What now? Does anybody has any idea what needs to be done to make this work in this context?

Thanks!

Gerard

Hi,

Thank you for your help. It has pointed me in the right direction, although in a different way than expected probably.

With process monitor, I found a set of "cmd.exe" executions, all running as the Administrator user that I had changed the application pool to run as. And that user has enough rights to run that command. That was not the problem. shell_exec was also not disabled in the php.ini file.

I also noticed that the tmp folder had a lot of "*.tmp" files, all with the html of the "mypage.view.php", from the example. So at least that part of the process ran alright.

What I did find in the list of cmd.exe in procmon was the specific command that executed phantomjs.exe. And it started with:

cmd.exe /c "C:\Users\gven\vqr\vqr-development\wwwendor\koolphp\koolreport\koolreport\packages\export\bin\phantomjs.exe --ignore-ssl-errors=true 

But if you look closely at the command line above, you see a number of strange characters in that line. It should be

cmd.exe /c "C:\Users\gven\vqr\vqr-development\www\vendor\koolphp\koolreport\koolreport\packages\export\bin\phantomjs.exe --ignore-ssl-errors=true

And apparently the "\v" and the "\e" get changed into a special character (is that a php thing? I am not a regular php user, so I am not sure). When I run the command like that in a cmd.exe window as an administrator, I saw that the command worked correctly.

I thought then that the strange characters in the phantomjs path might be caused by me adding

$mypage->export()
    ->settings(array(
    "useLocalTempFolder"=>true,
    "phantomjs"=>"C:\Users\gven\vqr\vqr-development\www\vendor\koolphp\koolreport\koolreport\packages\export\bin\phantomjs.exe"
))

In the index.php file in the example. I did this because originally I got an error that phantomjs.exe was not found. (Note that I installed koolreport with composer. Hence the slightly different folder structure than in your blog post about the export package).

What I did then is change the phantomjs path in the index.php file of the example into

"phantomjs"=>"C:/Users/gven/vqr/vqr-development/www/vendor/koolphp/koolreport/koolreport/packages/export/bin/phantomjs.exe"

with forward slashes instead of backward slashes.

That resolved the issue. The example now runs fine. And I can explore further. It may be a good idea to add something on the use of the back- / forward slash somewhere appropriate.
