[Phpwiki-talk] PHP Code in the Template Files

[Paul M. <pmm...@gm...>]

Hello.

I have searched for this information, but I can't seem to find it
anywhere, although I believe it to be possible.

I want to modify template files with a 1.2.7 clean install.

Essentially, I want to 'wrap' the wiki with elements form an existing
webpage (common headers, footer, ads, etc).

I have changed the template extension to .php and changed the
reference to it in config.php.  It loads the template as-is with the
new extension perfectly.  The problem is that the new php code I am
now inserting into it is not getting executed.

I have a require() at the top of the renamed template file, and then I
run a few custom canned functions from this included file (adRotate(),
displayUsers(), etc).  None of these execute properly when run from
within the .php template.

Do I need to make any other changes to execute php code in the
template?  This should (I think) be very straightforward but I can't
find any information about executing code on the WIKI itself or in
this mailist archives.

Thanks in advance,

Paul

with phpwiki-1.2.x php code is forbidden inside templates.
you have to use something higher than 1.3.6 or so.
before we just replaced some magic vars in the template string
and dumped that to the client.
now we eval the template.

Index of what?

$_COOKIE is only defined for php > 4.3
$HTTP_COOKIE_VARS is only defined globally, not locally.
Inside functions you have to global $HTTP_COOKIE_VARS or use $_COOKIE.

You just experience basic php problems.
phpwiki does not interfere with that.
Look at your /include/common.php and guard the
$_COOKIE['MemberName'] reference with
  if (isset($_COOKIE['MemberName'])) blabla...
otherwise you'll get these warnings, aeh notice.
