este caso é o mesmo que a perguntaPHP / MySQL:exibe algum erro após atualizar os dados com sucesso
isso porque em dashboard_engineer2.php seu código exibirá dados do banco de dados se a variável from, to, team for postada.
de delete.php redirecionar para dashboard_engineer2.php sendo o método get e os dados que foram postados anteriormente estão faltando
altere o delete.php codigo para ficar assim
<?php
$report_id = $_POST['report_id'];
$from = $_POST['from'];
$to = $_POST['to'];
$team = $_POST['team'];
$sql = "DELETE FROM ot_report WHERE report_id=:report_id";
$query = $conn->prepare($sql);
$query->execute(array(':report_id' => $report_id));
// so that the data previously posted is taken
// when redirecting to the dashboard_engineer2.php page
// even though it is a GET method
header("Location: dashboard_engineer2.php?from={$from}&to={$to}&team={$team}");
?>
e houve uma pequena mudança em dashboard_engineer2.php ser assim
<?php
// change the initial conditions to be like this
// $_REQUEST will get data if there is data in POST or GET
if(isset($_REQUEST["from"], $_REQUEST["to"], $_REQUEST["team"])){
$from = $_REQUEST['from'];
$to = $_REQUEST['to'];
$team = $_REQUEST['team'];
$result = '';
$query = "SELECT * FROM ot_report LEFT JOIN ot_users ON ot_report.badgeid = ot_users.badgeid WHERE ot_users.team_id = '".$team."' AND report_date BETWEEN '".$from."' AND '".$to."' ORDER BY ot_report.report_date DESC";
$sql = $conn->prepare($query, array(PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL));
$sql -> execute();
