getAbsModulePath()

Get the absolute path of the current module for this controller.


    public
                    getAbsModulePath() : string

TODO this might be too broad. It's only used for loading JSON forms and perhaps encourages bad behaviour. Such as assuming common path structures for all modules, where instead this should be written into the module class.

Parameters

$table : string: Table name
$record_id : int
$parent_log_id : int = 0: ID of a parent entry in the history_items table. This is used when multiple records are deleted by a single action. Undoing that action can then restore all of the deleted data.

                    loadRecord(string $table, int $record_id) : array<string|int, mixed>|bool

Used by the action log system, and disabled if the action log system has been turned off

Parameters

$table : string: Name of table to load record from
$record_id : int: ID of record to load

Should be called AFTER the action has been made. N.B. This is a low-level method; the friendlier wrapper methods are preferred; e.g. Controller::logAdd, Controller::logEdit

Parameters

$table : string: The table which had data modified by the query
$record_id : int: The id of the added/edited/deleted record
$type : string: ENUM value from history_items.type
$data : array<string|int, mixed> = []: Data associated with an add/edit. The handling differs based on the $type parameter: 'Add' ignored 'Edit' should be an array of the pre-update data, used to build a diff 'Delete' should contain the complete data of the deleted record 'Add category' should contain ['cat_id' => value] 'Delete category' should contain ['cat_id' => value] 'Change password' should be an empty array
$parent_log_id : int = 0: ID of a parent log entry in the history_items table. This is used when multiple records are deleted by a single action. Undoing that action can then restore all of the deleted data. N.B. This is only relevant for deletes

Matching is done on the 'id' field, as a result the $new_records arrays MUST contain an id field.

Parameters

$table : string: The table name. Do not include prefix.
$new_records : array<string|int, mixed>: The new records for the table. Should be an array of arrays, With each sub-array being the arguments which would normally be passed to Pdb::insert or Pdb::update

saveJsonData()

Automatically saves the data associated with a submission on a JSON-generated form

Parameters

$conf : array<string, array<string|int, array<string, mixed>>>: Config loaded from a JSON file
$item_id : int: Database ID of record to store data in. If zero, a new record will be inserted, and as this argument is a reference, it will be updated with the auto-increment ID generated by the insert.
$mode : string = '': Mode: 'add', 'edit', or something custom (e.g. 'duplicate', 'verify'). If blank, 'add' or 'edit' will be automatically determined, based on $item_id

Return values

bool —

True if the save succeeded. If false is returned, errors will be saved in $_SESSION
