Using “WP QuickLaTeX” formulas in Theme “WPLMS” questions

WP QuickLaTeX just replaces pieces of LaTeX code with URLs to images (PNG or SVG).
I believe this shouldn’t create any difficulties for AJAX themes.

WP QuickLaTeX processes only pages of standard types – posts, pages, etc.
But, I suspect that the theme uses custom-defined, non-standard type of content to create quizzes. The easiest solution would be to include WP QuickLaTeX parser/filter to handle these specialized pages.

This is only my guess, and developers of the theme are the most qualified to confirm this situation.

Thank you very much! I contact the developers of the theme again with these information!

I’ve heard back from the developers. Can you tell me which filter should be run on custom post types content?

The filter name is ‘quicklatex_parser’.

Please take a look on lines 305-311 in wp-quicklatex.php to see how to install it for custom post types.

Hi,

I have contacted the developers of the theme and they responded:

Okay thanks for confirming this . We have now applied the _content filter to our explanation in your site.Now the plugin should evaluate the shortcode and show the picture .
same fix will be added in next update of wplms theme and vibe course module plugin .

Unfortunately it still doesn’t work right and I was told

Well we have already applied the the_content filter on the explanation as suggested by the author .Now please contact this third party plugin author it is not working .
I would still recommend you using jetpack beautiful math addon for that .

Do you have any more insight? I really don’t want to use jetpack, even if it was just for the sake of using it in questions/explanations, because it just doesn’t offer me the full LaTeX potential.

@”Unfortunately it still doesn’t work right”

Could you please elaborate a bit, how it doesn’t work, what changed, test page to see the situation?

Of course. A test quiz can be found on my dummy site Quiz

You might have to register to get full access (you can also contact me via this form and I will create an admin account for you).

While taking the quiz, the formulas get displayed fine. However, once you are done with the quiz and want to see the results, there is the possibility to include an explanation on how to get to this answer. The question still displays everything fine, but in this explanation box no pictures are rendered.

Then, if you leave the answer page and maybe later want to check back on your answers via the user dashboard -> Courses -> Results, even the question gets messed up, because it seems that some of the backslashes get removed (resulting in code like $begin{pmatrix} 1 end{pmatrix}$ instead of $\begin{pmatrix} 1 \end{pmatrix}$).

I hope this makes it clearer and if there is any more information you need, I’m happy to provide it!

As for backslashes – please make sure that Markdown feature is disabled in JetPack. Usually it is responsible for stripping off the backslashes.

As for the equations in “answer explanation” – theme simply doesn’t apply QuickLaTeX filter to this text.

Are equations in “answer explanation” shown correctly when you use JetPack?

…when you use JetPack Math?

As of now I am not using JetPack Math for anything. This is what the theme developers suggested to do as this should work with everything their theme offers. I will look into Jetpack if there is no other way though (and will still use QuickLaTeX for everything else).

I set your account to “Admin”, so if you feel to look around and play with the theme/quiz yourself, please do so. I am still hoping that somehow it will get sorted out…do you think it would be worth to aim for a collaboration with the developers to include QuickLaTeX as a native plugin in the theme for every math related subjects?

Hi again,

this is where/how the filter was added: Link
Is this correct? If yes, there seems to be another problem as the problem persists.

For now I might go for a combined usage of JetPack for questions and WP QuickLaTeX for everything else on the website. If in the future there is a complete solution for QuickLaTeX that fixes this problem, I would of course switch back! Thank you so far for the support!

Hello again,

I was in contact with the theme developers again and the issue seems to be resolved. The fix will be added in the next update of the theme.

Congratulations on this and thank you for your donation!

Unfortunately we (as QuickLaTeX developers) can do very little when it comes to enabling third-party plugins & themes with QuickLaTeX support.
