FluentBoards Filter Hooks

FluentBoards Core Intermediate

FluentBoards has many filter hooks. Use them to change default settings and data, and to extend FluentBoards with new functionality.

What are Filter Hooks

A hook lets developers change functionality without editing core files. Filter hooks pass a value through your callback. Your callback returns the value, modified or unchanged, and FluentBoards uses whatever you return.

add_filter('fluent_boards/task_priorities', function ($priorities) {
    $priorities['critical'] = __('Critical', 'my-plugin');
    return $priorities; // always return the value
}, 10, 1);

Conventions used on these pages:

• Pass the correct number of accepted arguments (the 4th parameter of add_filter()). If a filter passes extra arguments and you need them, register with that count, for example 10, 2.
• Almost every hook name starts with fluent_boards/. The legacy exception fluent_boards_csv_mimes is noted on the hook.
• Pro means the filter runs only when FluentBoards Pro is active. Filters without the badge are applied by the free plugin. Pro may apply some of them too.
• Default shows the value the filter receives when nothing else has changed it.
• Source paths are relative to the plugin root. Paths that start with fluent-boards-pro/ are in the Pro plugin.

Removed or non-existent filters

• fluent_boards/task_tabs does not exist in FluentBoards or FluentBoards Pro. Each user's task tab order is saved as user meta from the task modal. No filter controls it.
