How can I get this form's active theme name in txp:php?
I have a page where I need to publish custom CSS in the head, instead of having it linked from an external file.
Prior to Textpattern 4.7, I was using rvm_css to write the custom CSS to files, and I had the following snippet in my template to pull in the CSS:
<txp:if_custom_field name="custom_css">
<txp:variable name="article_stylesheet_name"><txp:custom_field name="custom_css"/>.css</txp:variable>
</txp:if_custom_field>
<style>
<![CDATA[
<txp:if_custom_field name="custom_css">
<txp:php>
global $variable;
echo(file_get_contents('./css/' . strtolower($variable['article_stylesheet_name'])));
</txp:php>
</txp:if_custom_field>
]]>
</style>With Txp 4.7+, rvm_css adds the active theme name to the path, as a directory holding CSS assets. That makes sense, but I don’t know how to access that variable in my PHP.
Can anyone shed some light on this?
Thank you!

Perhaps page_url and type="theme_path" or type="themes_root" can help you. You should be able to do:
<txp:page_url type="theme_path" />/styles/<txp:custom_field name="custom_css"/>.cssor:
<txp:page_url type="themes_root" />/your-theme/styles/<txp:custom_field name="custom_css"/>.cssTXP Builders – finely-crafted code, design and txp

Thank you, @jakob!
Unfortunately, the path that this spits out isn’t compatible with my use-case.
The main thing is that PHP’s file_get_contents() function needs a path to the file on the disk, but the theme_path and themes_root tags (understandably) output URLs. Being part of the page_url tag, it makes perfect sense that they give you URLs.
I don’t want to ditch rvm_css because it lets the site editor create new static CSS files without messing around (and possibly messing up) the site theme. And rvm_css outputs CSS files to a directory named after the theme under the css directory you designate in preferences, not the theme directory itself.
For example, my theme directory looks is like this:
/document_root/themes/mysite.tld/*
But the rvm_css files live in a directory path like this:
/document_root/css/mysitetld/*
(Note that rvm_css strips out the dot from my theme name.)
It looks like, for now at least, I need to hard code the theme name in the template.
I thought Textpattern might have some way to expose the current theme name used by rvm_css so I can tell file_get_contents() where my CSS is on the disk.
But I guess that’s not the case right now.
Thank you again!

Looking at rvm_css code, it seems that the path is
global $pretext;
$csspath = get_pref('path_to_site').DS.
get_pref('rvm_css_dir').DS.
strtolower(sanitizeForUrl($pretext['skin'])).DS.
strtolower($variable['article_stylesheet_name']);This said, importing a flat file content into txp rather than linking to it is questionable.

Thank you, @etc! I should have thought to check the source of rvm_css.

This template is for generating ebooks via an external script. The script will use CSS that is rendered in the document, but won’t fetch external CSS files.

If file_get_contents() isn’t letting you use urls then it may be due to a security setting in your hosting environment. PHP can let you use the two systems (path or URL) interchangably to fetch content unless prohibited.
That reminds me: check smd_ebook for 4.7.x compatibility.

Makes sense, thanks. But then you could also import CSS from the db, I don’t think there is any difference performance-wise. We could even enable CSS output in 4.7.2 via, say, <txp:css format="inline" />.
