User setting Black or White page

I want my user to choose if the page is a White page or a Black page, at the moment I've got that set as an attribute so they can change it themselves and it changes the stylesheet.

This works fine as a rule, however I also need to change things in Layouts and PHP pages. But the attribute is set in a Content Template I don't see how I can effectively use that in the pages above (as it were).

The only way I can think of doing it is to have two versions of every Master Page, one with a Black attribute set and another with a White one, obviously that doubles changes work so does anyone have a better idea?

Thanks, Chris.

Are you using a page attribute for this?

Yeah, at the moment I've got the following in a page attribute.

<link rel="stylesheet" type="text/css" href="/perch/burrells/styles/<perch:pages id="style_type" label="Page Colour" type="select" options="Black|black, White|white" default="black" required="true" divider-before="Page Layout" />.css" />

Ok - and in which context are you having problems using that?

That works fine but only changes the stylesheet. I need the whole page to be aware that it is black or white so that it can get images from another directory.

I sort of need it as a system variable I suppose, but then I wouldn't know where the user could set it per page or how to then use that in both php and HTML templates.

You can use perch_page_attribute() to get that attribute back:

perch_page_attribute('style_type');

or

if (perch_page_attribute('style_type', true)=='black') {
    .... black ...
}else{
    ... white ...
}

or assign it into a template:

PerchSystem::set_var('style_type', perch_page_attribute('style_type', true));

and then use it in the template:

<perch:if id="style_type" match="eq" value="black">
   ... black ...
<perch:else />
   ... white ...
</perch:else>

Great thanks, thats almost worked, if I use it as a simple replacement ie

/img/<?php perch_page_attribute('style_type',true) ?>/logo.png

But it always prints to the screen, so I can't use it for if else statements or even add it to a system variable. When I do I just get 'white' or 'black' appear in text at the top of the page.

This will return:

 perch_page_attribute('style_type',true);

This will echo:

 perch_page_attribute('style_type');

So this:

/img/<?php perch_page_attribute('style_type',true) ?>/logo.png

should be this:

/img/<?php perch_page_attribute('style_type'); ?>/logo.png

I agree that should be the case but it isn't, the true doesn't appear to change anything, it always echos.

In one of my templates that I use in a layout file its coded like this:

<li>
    <a href="watches/<perch:content id="slug"/>" title="<perch:content id="brand"/>">
    <perch:if id="style_type" match="eq" value="white">
        <img src="<perch:content id="nav_white"/>" alt="<perch:content id="brand"/>"/>
    <perch:else />
        <img src="<perch:content id="nav_black"/>" alt="<perch:content id="brand"/>"/>
    </perch:else>   
    </a>
</li>

However the if else doesn't work and it outputs both images and at the top of the page before <html> there is simply 'black'.

I've set this in the header layout file, which is where the template should be reading it from.

$tempstyle = perch_page_attribute('style_type', true);
PerchSystem::set_var('style_type', $tempstyle);

The only reason I've added it to a variable is just to test that wasn't the problem.

In fact more reason seems to suggest that this line is what gets echo'd.

PerchSystem::set_var('style_type', perch_page_attribute('style_type', true));

Oh, sorry, my mistake. The second parameter is an options array. Set true as the third parameter to return.
