Member Function Documentation

◆ delete_data_content()

static mod_data\privacy\datafield_provider::delete_data_content ( $context,
$recordobj,
$fieldobj,
$contentobj )
static

Allows plugins to delete locally stored data.

Usually datafield plugins do not store anything and this method will be empty.

Parameters
context_module$context
stdClass$recordobjrecord from DB table {data_records}
stdClass$fieldobjrecord from DB table {data_fields}
stdClass$contentobjrecord from DB table {data_content}

Implemented in datafield_checkbox\privacy\provider, datafield_date\privacy\provider, datafield_file\privacy\provider, datafield_latlong\privacy\provider, datafield_menu\privacy\provider, datafield_multimenu\privacy\provider, datafield_number\privacy\provider, datafield_picture\privacy\provider, datafield_radiobutton\privacy\provider, datafield_text\privacy\provider, datafield_textarea\privacy\provider, and datafield_url\privacy\provider.

◆ export_data_content()

static mod_data\privacy\datafield_provider::export_data_content ( $context,
$recordobj,
$fieldobj,
$contentobj,
$defaultvalue )
static

Exports data about one record in {data_content} table.

Datafield plugins providers should implement this method to:

  • preprocess references to files in the response (examples - textarea, picture, file)
  • make content more human-readable (example - replace values separators in multimenu, format date in date)
  • add more information about the field itself (example - list all options for menu, multimenu, radio)

Sample implementation (from datafield_textarea):

$defaultvalue->content = writer\with_context($context) ->rewrite_pluginfile_urls([$recordobj->id, $contentobj->id], 'mod_data', 'content', $contentobj->id, $defaultvalue->content); writer\with_context($context)->export_data([$recordobj->id, $contentobj->id], $defaultvalue);

Parameters
context_module$context
stdClass$recordobjrecord from DB table {data_records}
stdClass$fieldobjrecord from DB table {data_fields}
stdClass$contentobjrecord from DB table {data_content}
stdClass$defaultvaluepre-populated default value that most of plugins will use

Implemented in datafield_checkbox\privacy\provider, datafield_date\privacy\provider, datafield_file\privacy\provider, datafield_latlong\privacy\provider, datafield_menu\privacy\provider, datafield_multimenu\privacy\provider, datafield_number\privacy\provider, datafield_picture\privacy\provider, datafield_radiobutton\privacy\provider, datafield_text\privacy\provider, datafield_textarea\privacy\provider, and datafield_url\privacy\provider.
