>4.1.1. What to Edit</H2
><P
> The template directory structure is that there's a top level directory,
<TT
CLASS="filename"
>template</TT
>, which contains a directory for
each installed localization. The default English templates are
therefore in <TT
CLASS="filename"
>en</TT
>. Underneath that, there
is the <TT
CLASS="filename"
>default</TT
> directory and optionally the
<TT
CLASS="filename"
>custom</TT
> directory. The <TT
CLASS="filename"
>default</TT
>
directory contains all the templates shipped with Bugzilla, whereas
the <TT
CLASS="filename"
>custom</TT
> directory does not exist at first and
must be created if you want to use it.
</P
><P
> There are two different ways of editing Bugzilla's templates,
and which you use depends mainly on the method you plan to use to
upgrade Bugzilla.
The first method of making customizations is to directly edit the
templates in <TT
CLASS="filename"
>template/en/default</TT
>. This is
probably the best method for small changes if you are going to use
the CVS method of upgrading, because if you then execute a
<B
CLASS="command"
>cvs update</B
>, any template fixes will get
automagically merged into your modified versions.
</P
><P
> If you use this method, your installation will break if CVS conflicts
occur.
</P
><P
> The other method is to copy the templates to be modified into a
mirrored directory
structure under <TT
CLASS="filename"
>template/en/custom</TT
>. The templates
in this directory automatically override those in default.
This is the technique you
need to use if you use the overwriting method of upgrade, because
otherwise your changes will be lost. This method is also better if
you are using the CVS method of upgrading and are going to make major
changes, because it is guaranteed that the contents of this directory
will not be touched during an upgrade, and you can then decide whether
to continue using your own templates, or make the effort to merge your
changes into the new versions by hand.
</P
><P
> If you use this method, your installation may break if incompatible
changes are made to the template interface. If such changes are made
they will be documented in the release notes, provided you are using a
stable release of Bugzilla. If you use using unstable code, you will
need to deal with this one yourself, although if possible the changes
will be mentioned before they occur in the deprecations section of the
previous stable release's release notes.

for inclusion in standard Bugzilla, you should read the relevant
sections of the

TARGET="_top"
>Developers'
Guide</A
>.
</P
></TD
></TR
></TABLE
></DIV
><P
> The syntax of the Template Toolkit language is beyond the scope of
this guide. It's reasonably easy to pick up by looking at the current
templates; or, you can read the manual, available on the
<A
HREF="http://www.template-toolkit.org"
TARGET="_top"
>Template Toolkit home
page</A
>.
</P
><P
> One thing you should take particular care about is the need
to properly HTML filter data that has been passed into the template.
This means that if the data can possibly contain special HTML characters
such as <, and the data was not intended to be HTML, they need to be
converted to entity form, ie &lt;. You use the 'html' filter in the
Template Toolkit to do this. If you forget, you may open up
your installation to cross-site scripting attacks.
</P
><P
> Also note that Bugzilla adds a few filters of its own, that are not
in standard Template Toolkit. In particular, the 'url_quote' filter
can convert characters that are illegal or have special meaning in URLs,
such as &, to the encoded form, ie %26. This actually encodes most
characters (but not the common ones such as letters and numbers and so
on), including the HTML-special characters, so there's never a need to
HTML filter afterwards.
</P
><P
> Editing templates is a good way of doing a "poor man's custom fields".
For example, if you don't use the Status Whiteboard, but want to have
a free-form text entry box for "Build Identifier", then you can just
edit the templates to change the field labels. It's still be called
status_whiteboard internally, but your users don't need to know that.

>4.1.3. Template Formats</H2
><P
> Some CGIs have the ability to use more than one template. For
example, buglist.cgi can output bug lists as RDF or two
different forms of HTML (complex and simple). (Try this out
by appending <TT
CLASS="filename"
>&format=simple</TT
> to a buglist.cgi
URL on your Bugzilla installation.) This
mechanism, called template 'formats', is extensible.
</P
><P
> To see if a CGI supports multiple output formats, grep the
CGI for "GetFormat". If it's not present, adding
multiple format support isn't too hard - see how it's done in
other CGIs, e.g. config.cgi.
</P
><P
> To make a new format template for a CGI which supports this,
open a current template for
that CGI and take note of the INTERFACE comment (if present.) This
comment defines what variables are passed into this template. If
there isn't one, I'm afraid you'll have to read the template and
the code to find out what information you get.
</P
><P
> Write your template in whatever markup or text style is appropriate.
</P
><P
> You now need to decide what content type you want your template
served as. Open up the <TT
CLASS="filename"
>localconfig</TT
> file and find the
<TT
CLASS="filename"
>$contenttypes</TT
>
variable. If your content type is not there, add it. Remember
the three- or four-letter tag assigned to you content type.
This tag will be part of the template filename.
</P
><P
> Save the template as <TT
CLASS="filename"
><stubname>-<formatname>.<contenttypetag>.tmpl</TT
>.
Try out the template by calling the CGI as
<TT
CLASS="filename"
><cginame>.cgi?format=<formatname></TT
> .

>4.1.4. Particular Templates</H2
><P
> There are a few templates you may be particularly interested in
customizing for your installation.
</P
><P
> <B
CLASS="command"
>index.html.tmpl</B
>:
This is the Bugzilla front page.
</P
><P
> <B
CLASS="command"
>global/header.html.tmpl</B
>:
This defines the header that goes on all Bugzilla pages.
The header includes the banner, which is what appears to users
and is probably what you want to edit instead. However the
header also includes the HTML HEAD section, so you could for
example add a stylesheet or META tag by editing the header.
</P
><P
> <B
CLASS="command"
>global/banner.html.tmpl</B
>:
This contains the "banner", the part of the header that appears
at the top of all Bugzilla pages. The default banner is reasonably
barren, so you'll probably want to customize this to give your
installation a distinctive look and feel. It is recommended you
preserve the Bugzilla version number in some form so the version
you are running can be determined, and users know what docs to read.
</P
><P
> <B
CLASS="command"
>global/footer.html.tmpl</B
>:
This defines the footer that goes on all Bugzilla pages. Editing
this is another way to quickly get a distinctive look and feel for
your Bugzilla installation.
</P
><P
> <B
CLASS="command"
>bug/create/user-message.html.tmpl</B
>:
This is a message that appears near the top of the bug reporting page.
By modifying this, you can tell your users how they should report
bugs.
</P
><P
> <B
CLASS="command"
>bug/create/create.html.tmpl</B
> and
<B
CLASS="command"
>bug/create/comment.txt.tmpl</B
>:
You may wish to get bug submitters to give certain bits of structured
information, each in a separate input widget, for which there is not a
field in the database. The bug entry system has been designed in an
extensible fashion to enable you to define arbitrary fields and widgets,
and have their values appear formatted in the initial
Description, rather than in database fields. An example of this
is the mozilla.org
<A
HREF="http://bugzilla.mozilla.org/enter_bug.cgi?format=guided"
TARGET="_top"
>guided
bug submission form</A
>.
</P
><P
> To make this work, create a custom template for
<TT
CLASS="filename"
>enter_bug.cgi</TT
> (the default template, on which you
could base it, is <TT
CLASS="filename"
>create.html.tmpl</TT
>),
and either call it <TT
CLASS="filename"
>create.html.tmpl</TT
> or use a format and
call it <TT
CLASS="filename"
>create-<formatname>.html.tmpl</TT
>.
Put it in the <TT
CLASS="filename"
>custom/bug/create</TT
>
directory. In it, add widgets for each piece of information you'd like
collected - such as a build number, or set of steps to reproduce.
</P
><P
> Then, create a template like
<TT
CLASS="filename"
>custom/bug/create/comment.txt.tmpl</TT
>, also named
after your format if you are using one, which
references the form fields you have created. When a bug report is
submitted, the initial comment attached to the bug report will be
formatted according to the layout of this template.
</P
><P
> For example, if your enter_bug template had a field
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><FONT
COLOR="#000000"
><PRE
CLASS="programlisting"
><input type="text" name="buildid" size="30"></PRE
></FONT
></TD
></TR
></TABLE
>
and then your comment.txt.tmpl had
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR

>4.1.5. Configuring Bugzilla to Detect the User's Language</H2
><P
>Bugzilla honours the user's Accept: HTTP header. You can install
templates in other languages, and Bugzilla will pick the most appropriate
according to a priority order defined by you. Many
language templates can be obtained from <A
HREF="http://www.bugzilla.org/download.html#localizations"
TARGET="_top"
>http://www.bugzilla.org/download.html#localizations</A
>. Instructions
for submitting new languages are also available from that location.
</P
><P
>After untarring the localizations (or creating your own) in the
<TT
CLASS="filename"
>BUGZILLA_ROOT/template</TT
> directory,
you must update the <TT
CLASS="option"
>languages</TT
> parameter to contain any
localizations you'd like to permit. You may also wish to set the
<TT
CLASS="option"
>defaultlanguage</TT
> parameter to something other than
<SPAN
CLASS="QUOTE"
>"en"</SPAN
> if you don't want Engish to be the default language.
