我成功地将一个参数添加到url中，但是我无法对其进行递增。例如，如果我单击“提交”按钮，则网址应从http://localhost/code/1转换为http://localhost/code/2。我已经隐藏了输入内容以访问url，但无法将其重定向到所需的值，该怎么办？这是我的PHP代码：
<?php
$cod=strtoupper($_GET['params']);
$i=$_GET['params1'];
$id_rezervare="SELECT id FROM trezervare WHERE numar_rezervare = '$cod'";
$id_rezervare = $db->DbGetOne($id_rezervare);
$cod_rezervare="SELECT UPPER(numar_rezervare) FROM trezervare WHERE numar_rezervare = '$cod'";
$cod_rezervare = $db->DbGetOne($cod_rezervare);
$cod_rezervare1 = strtoupper($cod_rezervare);
$nr_camere="SELECT count(*) FROM trezervarecont WHERE idrezervare= $id_rezervare ";
$nr_camere = $db->DbGetOne($nr_camere);
$checkin_status=TRUE;
$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$data_nasterii= $_GET['datanasterii'];
$test_arr = explode('/', $data_nasterii);
if(isset($_POST['trimite'])){
if (count($test_arr) == 3) {
if (checkdate($test_arr[0], $test_arr[1], $test_arr[2])) {
} else {
$message = "Date has an invalid format";
echo "<script type='text/javascript'>alert('$message');</script>";
}
} else {
$message = "No date selected";
echo "<script type='text/javascript'>alert('$message');</script>";
}
}
if(isset($_POST['trimite'])){
$i++;
}
?>
