Auto-rotation of the skin layer of themes by dates/season/holidays?

Destry · 2019-11-20 12:17:33

Let’s say I don’t want to do any deep structural changes with themes, but just want to change the ‘skin’ aspect of my theme, site-wide, on a seasonal basis, but without me having to manually switch it every three months.

How might that be approached? Not possible yet out of box?

You’re probably best off doing this in your template via conditionals. You can probably use <txp:evaluate> to test if the date, for example, lies within a range and include a different Stylesheet based on the result.

Edit: I’ll leave it as homework for Oleg to provide the most efficient example ;)

You can do it fairly simply with etc_date but I am sure evaluate can do something similar.

<txp:etc_if_date value="09-23 | 12-21" format="%m-%d">
	<txp:css format="link" media="" name="autumn" />
</txp:etc_if_date>
<txp:etc_if_date value="12-22 | 03-20" format="%m-%d">
	<txp:css format="link" media="" name="winter" />
</txp:etc_if_date>

I’ll second that. I’ve used etc_date for exactly this for years.

<txp:evaluate> may be more efficient, but etc_date works and is easy to use.

Thanks all.

Sorry, my kids are my exclusive homework furnishers :-) A hint: you can register PHP date function via Advanced options for use in <txp:evaluate />.

Just like my house.

And thanks for the hint.

crib sheet

month-<txp:evaluate query='<txp:php>print date ('m');</txp:php>' />

will be displayed:
month-01
month-02
…………………..
month-11
month-12

<img src="month-<txp:evaluate query='<txp:php>print date ('m');</txp:php>' />.png" >

Or even

<img src="month-<txp:php>print date ('m');</txp:php>.png" >

but we don’t consider <txp:php /> as “core” solution, right? However, if you register date function in PHP functions enabled in txp:evaluate pref, you will be able to call

<img src="month-<txp:evaluate query="date('m')" />.png" >

How to register a function for <txp:evaluate/> ?

<txp:php>print date ('m');</txp:php>
or
print date ('m');
or
date ('m');
php

This does not work.

What syntax should be?

Like this

Oh yeah! Here is how it works.

Thanks.

I tried many options here .

But just “data” did not understand.

Everything just worked. It turns out that can register the “time” and change the blocks during the day.

Great opportunities open up.

I love textpattern!
