OK! But changing isalpha() to isalnum() in ParsedString::get() in
htlib/ParsedString.cc did only the first part of the job.
I've defined an attribute 'use_template' (and patched into htsearch.cc),
which I use to select includes with different 'template_map'
definitions. Now my users are able to use different named combinations
of templates in 'template_map', without using any real path or file
names. This is something my administrator requested (Even 'common_dir'
is created out of an attribute 'template_dir' and the document root of
our server).
All a user can do, is to select a predefined template map and to define
the template descriptions shown in his form. Therefore he has to use
some attributes user1, user2 ... . And of course he can create his own
templates 'user1.html' and 'user2.html' ..., which he can put in his
'template_dir'.
I defined an attribute user1 in my form and tried to forward the
attribute in my templates for a refined search:
def.: <input type="hidden" name="user1" value="template1">
forward: <input type="hidden" name="user1" value="$&(USER1)">
htsearch shows the selected template in his output. But when I take a
closer look at the page source, I see this:
<input type="hidden" name="user1" value=")">
So the first request worked and produced the desired output, but I'm
unable to do a refined search because the forward of the attribute is
broken.
I had to change isalpha() to isalnum() in Display::expandVariables() in
htsearch/Display.cc to get the forwarding to work. See the diffs down
below.
Oh, and I'm using htdig 3.1.5.
