Member Function Documentation

◆ add_data()

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

inherited

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 = `''`
	)

inherited

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.

◆ add_latest_state_join()

Parameters

int $slot the question to add information for.

◆ base_sql()

quiz_attempts_report_table::base_sql ( \core\dml\sql_join $allowedstudentsjoins )
