The Countlinks formula counts the number of linked entries of the column type Link to other entries in the respective row.
Table linking is a basic requirement
You can create a column with the Countlinks formula only if you have linked two tables. Read here how to create such a link.
Scope of the Countlinks Formula
The Countlinks formula should be used whenever you want to display the number of entries of another table as a cross-reference.
For example, you can use this to map the number of registered participants from a separate table when planning a workshop. The link column would thus hold the names of all participants.
Using the Countlinks formula makes sense only if you enable the Allow link to multiple rows option when creating a column of the Link to other entries type. If the option were turned off, there would always be a one in the Countlinks formula field.
Create a Countlinks formula
- Create a new column of the type Formula for links.
- Give the column an appropriate name.
- Set the Countlinks option as the formula.
- Now select the link column whose entries you want to count in the Select link column in this table field.
- Click Submit.
