Working with add-ons
After you create a custom app, you can extend its capabilities with add-ons. Add-ons are predesigned sets of components that work together to provide additional features to your app. To use an add-on:
- Install the add-on (see below). This makes the add-on available to use in your custom app. Depending on what the add-on does, installing it can automatically add predesigned:
- tables and fields
- scripts
- value lists
- layouts
- If the add-on has layout objects, drag the add-on to your layout.
If needed, the add-on creates relationships between its new tables and the current table occurrence.
For example, when you install a simple phone numbers add-on, it adds a table with fields for a phone number and type, adds a value list for the type field, and adds a script for adding a phone number record in the related table. When you drag the add-on to your layout, it creates a relationship between the new table and the current table occurrence, then adds a portal to display the related phone numbers and buttons to add and delete phone numbers.
Add-ons can provide more advanced functionality. Many of the add-ons included in FileMaker Pro are JavaScript-enabled and require no advanced coding skills. To discover more add-ons, visit Claris Marketplace.
You can easily try out an add-on and, if you don’t want the add-on anymore, remove it from your file in a single step. Uninstalling an add-on removes everything that it originally added and optionally removes any tables, fields, and record data used by the add-on.
To install an add-on:
- In Layout mode, choose the layout to work on.
- Click in the status toolbar, then click Add-ons.
- Click , select an add-on, and click Choose.
The add-on appears in the add-ons list and is available to place on a layout.
To place an installed add-on on a layout:
- In the Add-ons tab, drag an add-on from the list to the layout.
To uninstall an add-on:
- In the Add-ons tab, right-click an add-on in the list and choose Uninstall Add-on.
About detectable primary key fields
Add-ons that create a relationship require that the current table has a detectable primary key field before you can place the add-on on the layout. If FileMaker Pro doesn’t allow you to place an add-on for this reason, create a detectable primary key field or modify an existing field so it can be detected.
To be detected, a primary key field must either be the default PrimaryKey field (or a copy of it) or meet one of the following criteria:
- the field uses an auto-enter serial number and the following options are selected:
- for auto-enter, Prohibit modification of value during data entry
- for validation, Unique value
- the field uses an auto-enter calculation that includes the Get(UUID) or Get(UUIDNumber) function and the auto-enter option Prohibit modification of value during data entry is selected
- the field is a stored calculation field that includes the Get(UUID) or Get(UUIDNumber) function
- the field uses an auto-enter serial number
