Question

我在sql数据库中上传路径时遇到问题。不显示所有路径。

这是php代码：

$rd2 = mt_rand(1000, 9999) . "_File";
if ((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0))
    $filename = basename($_FILES['uploaded_file']['name']);

$ext = substr($filename, strrpos($filename, '.') + 1);
if (($ext != "exe") && ($_FILES["uploaded_file"]["type"] != "application/x-msdownload"));
    $newname = "uploads/" . $rd2 . "_" . $filename;

if (!file_exists($newname));

if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $newname)));
    $query = "insert into files (file_id,floc,subid,fname,fdesc,tcid)
              values ($newstd,'$newname',
                      '".htmlspecialchars($_REQUEST['subid'], ENT_QUOTES)."',
                      '".htmlspecialchars($_REQUEST['fname'], ENT_QUOTES)."',
                      '".htmlspecialchars($_REQUEST['fdesc'], ENT_QUOTES)."',
                      '".$_SESSION['tcid']."')";

if (!@executeQuery($query)) {
    if (mysql_errno () == 1062) //duplicate value
        $_GLOBALS['message'] = "Given Subject Name voilates some constraints,
                                please try with some other name.";
    else
        $_GLOBALS['message'] = mysql_error ();
}
else
    $_GLOBALS['message'] = "Successfully New Subject is Created.";
}

closedb();

代码正常运行，并在数据库中显示如下：http://i.stack.imgur.com/Z5jmb.png

它假设显示uploads/2654_File_filename.docx

并且文件未上传。

表格在表格中：

<tr>
    <td> File</td>
    <td> 
        <form action="cursuri.php" method="post" enctype="multipart/form-data">
        <input type="file" name="uploaded_file" id="uploaded_file"></form>
    </td>
</tr>

我用过这个：http://www.w3schools.com/php/php_file_upload.asp但是没有工作

我使用xampp 5.6.8并且php.ini和file_uploads directive设置为On。

编辑 - newstd是：

$result = executeQuery("select max(file_id) as fid from files");
    $r = mysql_fetch_array($result);
    if (is_null($r['fid']))
        $newstd = 1;
    else
        $newstd=$r['fid'] + 1;


    $result = executeQuery("select fname as fid from files where 
     fname='" . htmlspecialchars($_REQUEST['fname'], ENT_QUOTES) . "'
 and tcid=" . $_SESSION['tcid'] . ";");

    // $_GLOBALS['message']=$newstd;
    if (empty($_REQUEST['fname']) || empty($_REQUEST['fdesc'])) {
        $_GLOBALS['message'] = "Some of the required Fields are Empty";
    } else if (mysql_num_rows($result) > 0) {
        $_GLOBALS['message'] = "Sorry Subject Already Exists.";
    } else {

  }
  $rd2 = mt_rand(1000, 9999) . "_File";
...
...

编辑：我忘了提及when i dont use a path he upload it in database。

Answer 1

您可以检查文件是否过大并超出这两种配置的限制：

post_max_size
upload_max_filesize

您可以使用以下命令查看文件中的值：

<?php
phpinfo();
?>

编辑：

另一个建议是放置if的主体括号，因为如果该语句有效则单行执行，不能被信任。我认为问题可能是：

if (!file_exists($newname));

另外，您插入数据库的方式是从$ _REQUEST而不是新名称中取名，并在何处存储路径？

Answer 2

我有一个＆＃34;全球＆＃34;表格和我推出的enctype =＆＃34; multipart / form-data＆＃34;在它中，它可以保存表中的路径。

之前在下面的表格中并且不认识它。

Exception in thread "main" java.lang.IllegalStateException: HashCode violation: the hashCode of tabu (Vehicle>10) probably changed since it was inserted in the tabu Map or Set.
