I use php code to generate the xml file. This php is invoked via an
AJAX call. After the xml file is generated I use the php command
exec(the_command_string_for_running_the_php);
How is the setup precisely? Since mixing client- and server-side
scripting is always a bit tricky, I just want to make sure I
understand correctly
If all is well, I'm guessing it looks a little like:
1° launch asynchronous request and return (client-side, Javascript)
2° generate the XML and send a response, indicating that it's ready to
be converted (server-side, PHP)
3° handle the response, by sending a second request, and return
(client-side, Javascript)
4° handle the second request, and send a response when complete
(server-side, PHP; your 'exec();' statement)
5° handle the new response, which could be something like setting the
'src' attribute of an IFRAME to the location where the PDF was
generated (client-side, Javascript)
Where step 3° (5° resp.) corresponds to the AJAX onreadystatechange()
handler attached to the request sent in step 1° (3° resp.).
When I do that, I get the error message "invalid flag after regular
expression". I posted to the php and javascript newsgroups, but
they said that it was probably from the fop.
Well, if you'll allow me to bounce back:
The error has nothing to do with FOP. It is an error raised by the
browser, pointing to invalid Javascript embedded in HTML. In the
nastiest case, it could simply be a silly missing quote somewhere in
the generated HTML... :/
HTH!
