applyCustomFilterHandlers()

Apply custom filter handlers for columns with complex filtering logic


    protected
                    applyCustomFilterHandlers(SelectQuery $query, array<string|int, mixed> $customFilterColumns, string $tableName, bool $canFilter, array<string|int, mixed> $currentFilters, mixed $currentView, array<string|int, mixed>|null $selectedSystemView, bool $dirtyFilters) : SelectQuery

Columns can define a customFilterHandler in their metadata to specify a static method that handles their filtering. This allows complex filter logic (like querying multiple tables) to be defined alongside the column definition rather than requiring special controller knowledge.

Filter values are extracted from:

Query string parameters (user-applied filters)
Saved user view configuration (when loading a saved view)
System view configuration (when loading a system view)

Parameters

$query : SelectQuery: The query to filter
$customFilterColumns : array<string|int, mixed>: Columns with customFilterHandler defined
$tableName : string: The main table name
$canFilter : bool: Whether user filtering is enabled
$currentFilters : array<string|int, mixed>: Current filter values from query params
$currentView : mixed: Current saved user view (or null)
$selectedSystemView : array<string|int, mixed>|null: Current system view config (or null)
$dirtyFilters : bool: Whether user explicitly modified filters

Return values

SelectQuery —

The filtered query

handleCsvExport()

Handle CSV export from grid result

Generates a CSV export response from the grid processing result. Supports two modes:

Query Mode (default): Uses the query from result to build SQL SELECT statements. Best for simple fields that map directly to database columns.
Data Mode: Pass pre-processed data with computed/virtual fields already populated. Best for exports that include calculated fields, virtual properties, or complex transformations that can't be done in SQL.

Column Value Resolution (in order of precedence):

exportValue callback in column metadata - custom formatting function
renderField path (e.g., 'member.name_for_herald') - for nested entity access
queryField for relation columns in query mode
Direct column key access on entity/array

Parameters

$result : array<string|int, mixed>: Result from processDataverseGrid() with isCsvExport flag
$csvExportService : CsvExportService: CSV export service instance
$entityName : string: Base name for the export file (e.g., 'members', 'warrants')
$tableName : string|null = null: Optional table name for fetchTable (e.g., 'Awards.Recommendations' for plugin tables) If not provided, uses ucfirst($entityName)
$data : iterable<string|int, mixed>|null = null: Optional pre-processed data. If provided, uses data mode instead of query mode. Data should be an iterable of entities or arrays with all computed fields populated.

Return values

Response —

CSV download response

isCsvExportRequest()

    protected
                    isCsvExportRequest() : bool

Return values

bool —

True if CSV export is requested

loadFilterOptions()

Load filter options from a data source


    protected
                    loadFilterOptions(array<string|int, mixed>|string $source) : array<string|int, mixed>

Supports multiple formats for filterOptionsSource:

Simple string (table name): Uses 'id' for value, 'name' for label
```
'filterOptionsSource' => 'Branches'
```

Array with table: Database table with full control

'filterOptionsSource' => [
    'table' => 'Waivers.WaiverTypes',  // Required: table name for fetchTable()
    'valueField' => 'id',              // Optional: field for option value (default: 'id')
    'labelField' => 'name',            // Optional: field for option label (default: 'name')
    'conditions' => ['is_active' => true],  // Optional: filter conditions
    'order' => ['name' => 'ASC'],      // Optional: sort order (default: labelField ASC)
]

Array with appSetting: Load from app settings (YAML array)
```
'filterOptionsSource' => [
    'appSetting' => 'Branches.Types',  // Required: app setting key
]
```
The app setting should contain a YAML array like: ['Kingdom', 'Principality', 'Barony'] Both value and label will be set to the array item value.

Array with method: Call a static method on a class to get options

'filterOptionsSource' => [
    'method' => 'getGatheringsFilterOptions',  // Required: static method name
    'class' => 'Awards\\KMP\\GridColumns\\RecommendationsGridColumns',  // Required: fully qualified class name
]

The method should return array of ['value' => string, 'label' => string].

Parameters

$source : array<string|int, mixed>|string: Source identifier string (table name) or configuration array

Return values

array<string|int, mixed> —

Filter options as array of ['value' => string, 'label' => string]

processDataverseGrid()

Process dataverse grid request with unified logic


    protected
                    processDataverseGrid(array<string|int, mixed> $config) : array<string|int, mixed>

This method handles all aspects of grid processing including view management, filtering, searching, sorting, and pagination. It supports both saved user views and system-defined views.

Parameters

$config : array<string|int, mixed>

Grid configuration with the following keys:

gridKey (string): Unique identifier for the grid
gridColumnsClass (string): Fully qualified class name for grid columns metadata
baseQuery (Query): Base query object to start with
tableName (string): Primary table name for field qualification
defaultSort (array): Default sort configuration ['field' => 'direction']
defaultPageSize (int): Default number of records per page (default: 25)
systemViews (array|null): Optional array of system views (for Warrants-style grids)
defaultSystemView (string|null): Default system view key (required if systemViews provided)
queryCallback (callable|null): Optional callback to modify query per system view
showAllTab (bool): Whether to show "All" tab (default: true for saved views, false for system views)
canAddViews (bool): Whether users can create custom views (default: true)
canFilter (bool): Whether user filtering is enabled (default: true). When false, users cannot add/remove filters via the UI or query parameters. However, filters defined by system views are ALWAYS applied regardless of this setting.
canExportCsv (bool): Whether CSV export button is shown (default: true)
showFilterPills (bool): Whether active filter pills/badges are displayed (default: true)
showViewTabs (bool): Whether view tabs are displayed (default: true)
enableColumnPicker (bool): Whether column picker is available (default: true)
lockedFilters (array): Array of filter column keys that cannot be removed by users. Locked filters will not show remove (×) buttons and their values cannot be cleared via query string parameters. Useful for embedded grids where context filters (e.g., member_id) must always be applied.
enableBulkSelection (bool): Whether row selection checkboxes are shown (default: false)
bulkActions (array): Array of bulk action button configurations when enableBulkSelection is true. Each action is an array with keys: label, icon, modalTarget, permission.

NOTE: Authorization scope must be applied to baseQuery BEFORE calling this method. Use $baseQuery = $this->Authorization->applyScope($baseQuery, 'index'); in your controller before passing the query to processDataverseGrid().

Return values

array<string|int, mixed> —

Result array with keys: data, gridState, columnsMetadata, etc.

resolveNestedValue()

Return values

mixed —

Resolved value or null if path doesn't exist
