for ($i=0; $i <count($_POST['name']) ; $i++) { 
                    if (isset($_POST['name']) && isset($_POST['NIK'])) 
                    {
                        $_SESSION['NIK'][$i] = $_POST['NIK'][$i];
                        $NIK = $_SESSION['NIK'][$i];
                        $_SESSION['name'][$i] = $_POST['name'][$i];
                        $name= $_SESSION['name'][$i];
                        $query = mysql_query("SELECT * FROM jabatan AS t JOIN karyawn AS s WHERE  s.id_jabatan LIKE t.id_jabatan AND s.nama_karyawan LIKE '%{$nama_karyawan}%' AND s.NIK LIKE '%{$NIK}%' ");
                        $row = mysql_fetch_array($query);
                        $_SESSION['job_name'] = $row['job_name'];
                        $_SESSION['division'] = $row['division'];
                    }
                ?>

我想问如何在多输入中使用会话？
因为当我更改页面并返回该页面时，它显示错误

未定义的索引：C：''xampp''htdocs''training''output_main.php 中的名称 22号线

这意味着代码for ($i=0; $i <count($_POST['name']) ; $i++)

请帮助我的会话如何工作，我只是在学习 PHP。

我认为

会话不是问题，但如果您返回此页面，我想不再有 $_POST['name']。

您需要检查您的 $_POST['name'] 是否不为空

if (isset($_POST['name'])) {
   $postName = $_POST['name'];
}  elseif (isset($_SESSION['name'])) {
   $postName = $_SESSION['name'];
} else {
   Die('no post or session.');
}
for ($i=0; $i <count($postName) ; $i++)
                if (isset($_POST['name']) && isset($_POST['NIK'])) 
                {
                    $_SESSION['NIK'][$i] = $_POST['NIK'][$i];
                    $NIK = $_SESSION['NIK'][$i];
                    $_SESSION['name'][$i] = $_POST['name'][$i];
                    $name= $_SESSION['name'][$i];
                    $query = mysql_query("SELECT * FROM jabatan AS t JOIN karyawn AS s WHERE  s.id_jabatan LIKE t.id_jabatan AND s.nama_karyawan LIKE '%{$nama_karyawan}%' AND s.NIK LIKE '%{$NIK}%' ");
                    $row = mysql_fetch_array($query);
                    $_SESSION['job_name'] = $row['job_name'];
                    $_SESSION['division'] = $row['division'];
                }
            ?>
