A friend asked me to help them place a paypal button on their tumblr page. They had tried to place the code in the wysiwyg offered in the page's editing panel, but that stripped the code needed for the button to work. This is for good reason, so I checkout out the theme template. In my experience, blog systems like this are gnarly long templates with a ton of if page is 'about' { // show this } type blocks with many post types and search and tag-tree mini templates etc. with everything you could ever need in the template rendered when appropriate.
I've looked over the documentation and I found a few useful keys: https://www.tumblr.com/docs/en/custom_themes#pages such as {URL}, {Label}, {PostId}, {CurrentPage}, {ShortURL} etc.
My first expectation would be that there may be a class on the body associated with the current page which I could use to hide/and show with just CSS (this is a just a quick fix for a friend) - but there is no class or id or anything I can hook into. I figured I could get some conditional templating such as:
{block:AboutPage}
Only show on about page
{/block:AboutPage}
...but nothing like that exists as far as I can tell. I've tried using all of the page variables and haven't had any luck with any of my tests. Current page is referring to the index in a pagination setup... so it's always 1 on a static page. {ShortUrl} doesn't return anything. Is there a larger loop that I'm not understanding?
Conditional templating would be best, but I was at least hoping to build a tiny function that would add a slug to the body or something to get by. I used the label and dasherized it, which could work for CSS styles - but if he changes the page name it would break.
What am I missing? Is this not a standard need? Am I using the wrong search terms?
Here is an article with a hack to show something only on all static pages... http://beta.beantin.se/customised-tumblr-theme-static-pages/ but that doesn't really help me - and I think that {StaticURL} may have been changed since.
