标头php不起作用

Question

I made a code in php where a query is made I can not publish database connection data because they are confidential, but the code works fine, the query does work, the problem is that the header does not work only shows me the White screen

$buscar = 'DELETE FROM usuarios WHERE idusuario = "'.$_POST['prop'].'"';
$usuariorecord = mysqli_query($landier, $buscar);
$idi=mysqli_insert_id($landier);


$go = "../final.html";
header(sprintf("Location: %s", $go));

?>

thank you

Answer 1

You have query of remove data then why are you fetching inserted id?

Remove this line from code then try:

$idi=mysqli_insert_id($landier);

Answer 2

mysqli_insert_id（$ landier）//如果最后一个查询不是插入或更新查询，则返回零.....删除该特定行......
