Folder not valid

Cybertinus · 06-10-2011, 04:20 AM

Hello everybody,

I'm trying to build a simple tool in PHP to automatically convert eBooks from PDF to HTMLZ (I need to do some processing afterwards, so I need HTMLZ). But I get the following error from ebook-convert.exe:

Code:

Python function terminated unexpectedly
  Folder not valid (Error Code: 1)
Traceback (most recent call last):
  File "site.py", line 103, in main
  File "site.py", line 84, in run_entry_point
  File "site-packages\calibre\__init__.py", line 15, in <module>
  File "site-packages\calibre\constants.py", line 126, in <module>
ValueError: Folder not valid

What can cause this? I run the following command:

Code:

"C:\Program Files (x86)\Calibre2\ebook-convert.exe" C:\inetpub\wwwroot\epubgenerator\work\Pink_Cover039.pdf C:\inetpub\wwwroot\epubgenerator\work\Pink_Cover039.htmlz > error 2>&1

The error above is the complete content of the error file.

When I copy the command to the cli, it works perfectly

.

Does anybody what can be wrong? I've checked the permissions on the file Pink_cover039.pdf and Everyone has all permissions, so that can't be the problem.

It is probably the backslashes. Backslash is the escape character in PHP (as it is in most languages). PHP is trying to convert \e and the like to their escaped equivalents.

Either double the backslashes (so they escape themselves) or convert them to front slashes.

Hi Chaley,

I've tried changing the \ to /, but it had no effect. The same error popped up

.

Looking at the python code throwing the error, it has to do with finding your calibre configuration directory. I have no idea how php interacts with windows concerning environment vars and the like.

Second-to-last suggestion: write your script in python instead of PHP.

Last suggestion: put your command into a .bat file and have your PHP code exec the bat file. That gives you something to debug, as you can see and set environment variables before calling ebook-convert.exe.

Good luck!
