Doesn't seem to work if you have "=" in the value, for example you want to build a URL:
C_URL=https://some.query.url/search?q=
Then later in the document I have a reference like:
My URL = [[%%C_URL%%123456|123456]]
Or even an SQL plugin query like:
CONCAT('<a href="%%C_URL%%', reg.companyNumber, '">', reg.companyNumber, '</a>') AS companyNumber,
It doesn't resolve if the value contains "=", but if I take this out, it works.
I tried various methods to escape the "=" but it didn't work:
C_URL='https://some.query.url/search?q='
C_URL=https://some.query.url/search?q\=
C_URL=https://some.query.url/search?q\\=
C_URL=''https://some.query.url/search?q' . '=''
