Constructor & Destructor Documentation

__construct()

flexible_table::__construct

(

$uniqueid

)

Constructor.

Parameters

string

$uniqueid

all tables have to have a unique id, this is used as a key when storing table properties like sort order in the session.

Reimplemented in tool_dataprivacy\output\expired_contexts_table, enrol_lti\manage_table, webservice\token_table, quizaccess_seb\local\table\template_list, quiz_statistics_question_table, core_tag_manage_table, tool_usertours\local\table\step_list, and table_sql.

Member Function Documentation

add_data()

flexible_table::add_data	(		$row,
			$classname = ''
	)

This method actually directly echoes the row passed to it now or adds it to the download.

If this is the first row and start_output has not already been called this method also calls start_output to open the table or send headers for the downloaded. Can be used as before. print_html now calls finish_html to close table.

Parameters

array	$row	a numerically keyed row of data to add to the table.
string	$classname	CSS class name to add to this row's tr tag.

Return values

bool

success.

add_data_keyed()

flexible_table::add_data_keyed	(		$rowwithkeys,
			$classname = ''
	)

Add a row of data to the table.

This function takes an array or object with column names as keys or property names.

It ignores any elements with keys that are not defined as columns. It puts in empty strings into the row when there is no element in the passed array corresponding to a column in the table. It puts the row elements in the proper order (internally row table data is stored by in arrays with a numerical index corresponding to the column number).

Parameters

object | array	$rowwithkeys	array keys or object property names are column names, as defined in call to define_columns.
string	$classname	CSS class name to add to this row's tr tag.

can_be_reset()

flexible_table::can_be_reset ( )

protected

Are there some table preferences that can be reset?

If true, then the "reset table preferences" widget should be displayed.

Return values

bool

col_fullname()

flexible_table::col_fullname

(

$row

)

Fullname is treated as a special columname in tablelib and should always be treated the same as the fullname of a user.

@uses $this->useridfield if the userid field is not expected to be id then you need to override $this->useridfield to point at the correct field for the user id.

Parameters

object

$row

the data from the db containing all fields from the users table necessary to construct the full name of the user in current language.

Return values

string

contents of cell in column 'fullname', for this row.
