Test Post with a Tag with Commas
As the title says, this is a WordPress post with a comma separated tag. Sometimes this comes in handy, for example when you want to display a taxonomy called “restaurant, bar” or a city and it’s country: “Groningen, the Netherlands”. This is all done using a simple WordPress filter, are you interested in the code?
WordPress taxonomy contains comma, i.e allow commas in tag names.
/**
* WordPress filter for tags with commas
* replace '--' with ', ' in the output - allows commas in tag names this way
* e.g. save tag as "Fox--Peter" but display like "Fox, Peter"
* or "cafe--restaurant" for a tag "cafe, restaurant"
