Hejhej!

I'm pretty new to LimeSurvey, so excuse me if this is a dump question, but my client wants the option to add a different (or even multiple) different Logo(s) for different Surveys (without altering the theme or changing the main logo).

Is there a way I can provide that option? At least a single, changing logo should be possible, shouldn't it? What code do I need to add to the nav_bar.twig? How does the client add the logo within the survey?

I hope the the question wasn't answered before, but I wasn't able to find anything really helpful with the search.

Thanks in advance, all the best

In nav_bar.twig, you can add something like this to the logo option block.

It will insert an image - logo.png - found in the survey resources image folder.

Your client can upload the survey-specific images via the Resources tab in the survey menu.

In my opinion : best way is to add multiple logo system inside theme system.

In skelvanilla, i have 3 logo, then one can be the global one, and anoptherone the survey one

This need more work
but since it's a client : you can make a quote.

I suspect the work you have to invest into answering RFQ and handling is more expensive than the willingness to pay.

This is a typical example for a LimeStore offer or Themebundle.
50-100 EUR per year for an constantly updated theme, which is actually working without consulting the forum for one fix here and another workaround here. Just working is the key. If LS3/LS4 is constantly breaking parts, it will turn into a support nightmare.

Thank you very much @tpartner, works like a charm. Additional Question, though: Is there a way to check if a file exists (within the .twig file) in order to just display the logo if the file actually exists?

Can't get the PHP function file_exists to work and .twig does not seem to know a similar function.

Thanks again for the help!

Hi,
if it doesn't exist it cannot be displayed.
In that case the alt-value is used.
In Tony's example the name of the survey is displayed.

If you don't want that, use: alt=" " or enter the path toan existing (default) image.
Only alt="" will show the "image not found" symbol.

What LimeSurvey version are you using?

In 4.x, you can create custom twig functions incorporating PHP.

Maybe try with github.com/LimeSurvey/LimeSurvey/blob/2b...g_Extension.php#L287

Yes, maybe and ?

Else : skelvanilla is free , and can be easily apdated

Thanks again for your help everyone. A lot of great input, but I went with a super simple JavaScript solution (to match the very limited budget of the client).

See you next time, have a good one everyone!

Hi lucasdidthis

Could you share your solutions?

I have the same problem,Thank you，

Sure. I just added
to the image-tag with the second logo and use
in the css stylesheet to hide the empty element.
It's not the cleanest solution, but it works and was super fast and easy to implement.
