When my variable has an apostophe in it, it cannot be used for onshow

I’m using a conditional in templating engine tinybutstrong to show a <div> when a variable is not blank.

<div class="notice">[onshow;block=div;when [var.notice;noerr]!=''][var.notice;noerr]</div>

It works well except for when the $notice variable has an apostrophe ' in it. Otherwise the onshow conditonal doesn’t run.

How do I fix this?

Answer

The values may have quotes, you have to use delimiters and escaping :

<div class="notice">
   [onshow;block=div;when '[var.notice;strconv=esc;noerr]'!='']
   [var.notice;noerr]
</div>

The manual has been updated in order to have this clearer.

But is you case, using a magnet seems smarter:

<div class="notice">
   [onshow.notice;noerr;magnet=div]
</div>
