Question

它保存数据中的所有内容，但不保存更新文件的名称。它显示了17,18,19,20行中未定义的索引，它没有显示数据库中的PIC列中的任何内容。没有任何内容存储在subjects_pic文件夹中。

此处显示代码：

<?php
include('conect.php');
$d = '';
$qre = mysql_query("select * from courses1");
while ($res = mysql_fetch_array($qre)) {
    $d .='<option value="' . $res['cid'] . '">' . $res['cname'] . '</option>';
}
?>
<?php
include('auth.php');
include('conect.php');
$msg = '';
if (isset($_POST['save'])) {
    $course = $_POST['courses1'];
    $subjects = $_POST['subjects'];
    $name = $_POST['name'];
    $file_name = $_FILES['f1']['name'];
    $file_type = $_FILES['f1']['type'];
    $file_size = $_FILES['f1']['size'];
    $file_tmp = $_FILES['f1']['tmp_name'];
    $file_path = '../subject_pic/' . $file_name;
    move_uploaded_file($file_tmp, $file_path);
    mysql_query("INSERT INTO up_file (cid,subid,name,pic) 
    VALUES ('$course','$subjects','$name','$file_name')");

    $msg = '<h3>Record Saved</h3>';
}
?>
