I understand $HTMLStylesFmt to list css attributes, which get injected into styles.../styles tags in the page's HTML head section (to put it briefly). So an admin or developer can use $HTMLStylesFmt[] = some HTML selectors with css attributes; to add these attributes to the $HTMLStylesFmt array and thus inject them into the styles tags. It just means adding a new element to the array. If you give it a name, like $HTMLStylesFmt['mycss'], then it will be added to the array with that key name, instead of a numerical key. This is useful for situations where otherwise it may be added several times with the same css atributes, to avoid such repetitions. I used that in markup functions, where the same markup may be used several times in a page. ~Hans ___ pmwiki-users mailing list pmwiki-users@pmichaud.com http://www.pmichaud.com/mailman/listinfo/pmwiki-users

That's because the PageVar needed to be quoted, as Hans showed. Thus,

There were in fact several things wrong with your code:
1. missing quotes
2. wrong function: PageTextVar() is used to exctract a PTV
3. use of $pagename: use $pn rather than $pagename as $ pagename may
have a different value.
4. PTV name: if the PTV is named in the page 'myvar', then
that should be used a parameter in the PageTextVar() call.
PageVar($pn, myvar)
{$:myvar} is the syntax to refer to th ePTV in a wiki page.

Yep.

Actually, either function works, as PageVar calls PageTextVar. It is
probably mildly faster to call PageTextVar directly though.
3. use of $pagename: use $pn rather than $pagename as $ pagename may
have a different value.
Not sure about this. Is $pn globally available? Not sure, but it doesn't
look like it. I'd always thought $pagename referred to the current page
from within skin/config files.
4. PTV name: if the PTV is named in the page 'myvar', then
that should be used a parameter in the PageTextVar() call.
PageVar($pn, myvar)
{$:myvar} is the syntax to refer to th ePTV in a wiki page.
That's correct when calling PageTextVar. But called from PageVar, then
the $:myvar format is used.

why don't you just set the color attributes in

css file is to have one location for changing atributes

via a php variable, unles one wants to dynamically

~Hans
The current site uses only one set of colours, so it's easier to keep
them in the style tag and only deal with one file. I've used separate
css files before, but it's overkill for this one.
The reason I want a variable is if I use #006600 for several different
elements (H#, A, HR, various borders) then want to try #007700, I have
to change each and every occurence. Yes, I can use the editor's
search-and-replace, but a variable seems more elegant. Separating it
into a separate css file wouldn't change that.
I could do the style as
H1, H2, ... A.hover
{color:#006600;}
so the color number occurs only once, but I suspect there's a reason
I've never seen a file done that way.
Now to stop chatting and start experimenting.
Thanks,
Sandy

Experiments done for now. Several things work in group.php but not
testskin.php.
I'd like to start with all the skin code in the skin folder so it can
easily be moved between farms. Further customizing can then be done in
either php file, depending on the setup of the new farm.
Result of experiments: Very confused, especially the last result. Must
learn more about skin.php files and experiment more, and re-read the php
tutorials. Trying to learn too many things at once.
Thanks for the help.
Sandy
Results of experiments:
-
$color1 = '#00cc00';
$HTMLStylesFmt['my_skin'] = h1 {color:$color1;} ;
works in the group.php, but not in testskin.php .
-
in group.php:
$FmtPV['$color1']='#00cc00';
then in .tmpl
style
h1 {color:$color1;}
/style
works.
Same thing in testskin.php gives this html:
h1 {color:gold1;}
Suspect $FmtPV['$color1'] is being over-ridden by a recipe. No clue
which one.
Try testskin.php again, with different variable name. Resulting .html is:
h1 {color:$Sandy1;}
One has $ and one doesn't. Probably means something to someone who
finished the php tutorials.
--- -
add to each php file:
print_r($HTMLStylesFmt);
Works in group.php. Doesn't work in testskin.php.
add line of garbage to testskin.php
yes, the file is being called.
in group.php:
$FmtPV['$sandy1']='#00cc00';
in testskin.tmpl
style
h1 {color:$FmtPV['$sandy1'];}
/style
Resulting html:
h1 {color:$FmtPV['#00cc00'];}
Rechecked that one with different variable names three times. Offically
confused.

Aha! Googling the right terms helps. A way to use php to create a css file. http://www.barelyfitz.com/projects/csscolor/ Probably old news to many, but new and intriguing to me. Just checked the PmWiki docs, and yes I can have more than one php file in the skin folder. Something for me to play with next weekend. Sandy Key lines: + To use PHP in your CSS file: 1. Rename your style.css file to style.php, then add the following to the top of the file: ?php header(Content-type: text/css); ? This line tells the browser that the file is CSS instead of HTML. 2.

Dear pmwiki-users,
I have a lot of fun discovering pmwiki and I already like it very
much.
One thing I can't figure out, even after reading many pages on
pmwiki.org:
I would like to use a variable in my skin template. Ideally, this
would be similar to the
(:title Title of Page:)
markup, but I'd be ok with using a PageTextVariable. So, is it
possible to use such a variable in the skin template? {*$:MyVariable}
does not seem to work. (It does work in the SideBar or in a
GroupHeader, but not within the skin template.)
To use a PHP variable within a skin template you need to store it as a
FmtPV variable, which needs to be a executable PHP statement (thus the
odd quotes). Refer to PmWiki/PageVariables:
$FmtPV['$MyVar'] = 'abc';
And then to use it in the .tmpl file:
My quote of the day is {$MyVar}
In case it helps to know what I want this for: I'd like to print some
quote on each page in the very top of the page. I could use a
WikiStyle with absolute positioning CSS, but I imagine using a
variable within the templage (just like {$Title}) would be more
elegant.
(Or is the standard way to use a GroupHeader? I tried this but the
content of the GroupHeader is shown at the top of the page content,
not within the skin's HTML.)
You might be better off doing this in the GroupHeader -- that will
provide a little more flexibility if you decide that some pages don't
need a quote.
So, just edit the group header from within PmWiki and add the FmtPV you
declared:
Here's my variable {$MyVar}

then in the .tmpl file:

then when the client changes his mind, I only have to change it once.

Then maybe it is easiest to use div markup for those quotes, with a
specific class name, and use css to set the div where you want it.
But you would need to absolutely position it.
for instance
in page content:
topquote
here is a quote..
in pub/css/local.css:
.topquote {
position:absolute;

How about just using the PTV from the GroupHeader? So user defines the
PTV in the page body:
MyQuote:Here's my quote
Or hide it with:
(:MyQuote:Here's my quote:)
And in the group header:
myquoteclass
My quote is {$:MyQuote}.
