Problem: How should I save and display currency values effectively?

Solution:
Enter numbers using "point" for decimals. Commas are not currently supported here.

1.00
10.99
1000.00
...and so on...

Sorting works automatically when numbers are entered in this format. Filtering numbers with decimals effectively requires a small code change. This code change is described here:

To show the currency, hard-code it into the display of a field. The currency type does not get stored in the database with the value, so sorting and filtering continues to work as expected. Example:

€[wpv-post-field name="my-price-slug"]
$[wpv-post-field name="my-budget-slug"]

In the field description for each custom field, you can add a note that tells the user which currency should be used. This will show up in the admin editor area for your post.
