ListCount(...): Returns the number of items in a delimited list
| ListCount() | ListCount is used to return the number of items that exist in any given field, using any given delimiter. |
|---|---|
| Construction | ListCount(Field to count,Delimiter to use) Field to count: Typically, this will be a list type field, but this is not compulsory. The data in any field can be parsed using any chosen delimiter Delimiter to use: This is optional. If not specified, the function will default to using a semi-colon delimiter. Anything can be specified as a delimiter, from a single character to a whole word or words. |
| Examples | listcount([People]) No delimiter has been specified here, therefore the function will default to using a semi-colon. The result here will match the number of people shown in a properly tagged photo. Note that the function is smart, so, if a file has no [People] tag, the function will return zero (0), and if it has [People] data, but no semi-colon, the function will return one (1). |
