Problem Description
After changing in **Moodle** the **html_table** into **flexible_table**, I get the first **row** as completely **empty** and because of that the **sorting** doesn't work.
I changes the tables, because the html_table doesn't have sorting capabilities.
The code is:
ob_start();
$table = new flexible_table('Cars');
$table->define_baseurl(new moodle_url("/blocks/cars/view.php"));
$table->define_columns(array(
'carname',
'carnumberplate',
'carhiredate',
'city',
'actions',
));
$table->define_headers(array(
get_string('carname', 'block_cars'),
get_string('carnumberplate', 'block_cars'),
get_string('carhiredate', 'block_cars'),
get_string('city', 'block_cars'),
get_string('actions')
));
$table->sortable(true, 'cars');
$table->collapsible(false);
$table->set_attribute('cellspacing', '0');
$table->set_attribute('id', 'view-block-cars');
$table->set_attribute('class', 'generaltable');
$table->setup();
// Add one blank line
$table->add_data(NULL);
$strdateformat = get_string('strftimedate');
$strtimeformat = get_string('strftimetime');
foreach ($cars as $car) {
$datestart = userdate($car->starttime, $strdateformat);
$dateend = userdate($car->endtime, $strdateformat);
$timestart = userdate($car->starttime, $strtimeformat);
$timeend = userdate($car->endtime, $strtimeformat);
$date = $datestart;
if ($datestart != $dateend) {
$date .= ' - '.$dateend;
}
$time = $timestart.' - '.$timeend;
$actions = array(
html_writer::link($car->get_view_url(), get_string('view')),
);
$actions = implode(' | ', $actions);
$row = array(
format_string($car->carname),
format_string($car->platenumber),
$date,
format_string($car->city),...
