Re: How do I suppress a "missing form" error?

Haha. Shall we just remove every single <txp:...> tag in Textpattern 5 and replace it with etc_query? 🤣

Re: How do I suppress a "missing form" error?
Hehe, then my sites seem already running on txp 5.
Actually, <txp:image_info /> is probably not the best place for it, but <txp:evaluate /> might implement some raw xml import/process functionality, since it already uses a dom parser. Even in 4.9, maybe?

That’s a great idea. Love it. And not just applicable to images.
If it can be squeezed in now then it rounds off the SVG support nicely and paves the way for other amazing front-end processing tricks.

Re: How do I suppress a "missing form" error?
Woah, this thread came a long way since I last checked in. Great feedback and ideas. Philippe, that makes absolute sense what you say. My case is a logo with different coloured parts that change with different backgrounds. I thought i was “being clever” by assigning the path groups inside the svg a css variable as the colour (with fallback) and then setting that variable via css depending on context. But I wonder if it’s backfiring by making the page source larger and not so easily cacheable. What is your educated opiniion on these options:
- The ‘clever’ way with the svg inserted into the source two (sometimes three) times with css variables doing the colour switching.
- Saving three preset colour variants of the logo and simply inserting the svgs as images. Presumably, the browser doesn’t need to reload what has already been loaded on another page?
- Variant 1 but using etc_cache to store the inserted svgs. Perhaps that retrofits caching to the insert-in-source variant?
One other idea (that I need to check). You can insert svg collections as symbolsets and then use the svg symbols in your pages. I can’t remember precisely, but I have an inkling that you can control some (all?) of the contents via css. The symbolset file is loaded once as an external resource, so is potentially cached by the browser.

Exactly. So what would be a natural syntax:
form="my_form?", maybe?
Of the two, |* or ? I think I prefer the pipe-star.

That last option (external SVG with <use /> suffers from the same problem as the <img src=""> approach in that you can’t go into the shadowdom – all you can style is the <svg/> itself. This article (dev.to/javar/external-svgs-that-you-can-style-2a37) suggest a possible but limited workaround with fill="currentColor" I haven’t tested.
Depending on the size of the SVG option 2 (use multiple versions loaded as img) is probably the most performant but a little less flexible. Inserting the whole SVG block (minified?) in the html is more flexible. Caching is a bit more of an issue, but gzip works very well on SVG blocks. And as you say, etc_cache might help.
