我正在尝试从一个页面中的 php 脚本接收文件的名称，并将其附加到单独页面上的 javascript 函数中。问题是我在我的错误控制台中收到一个无效的正则表达式标志 w 错误，该错误声明未定义变量：'fileimagename for the line below:

 var nameimagefile = <?php echo $fileimagename; ?>;

我该如何解决这个错误？

下面是javascript函数（QandATable.php）：

function stopImageUpload(success){

     var nameimagefile = <?php echo $fileimagename; ?>;
      var result = '';
      if (success == 1){
         result = '<span class="msg">The file was uploaded successfully!</span><br/><br/>';
         $('.listImage').append(nameimagefile + '<br/>');
      }
      else {
         result = '<span class="emsg">There was an error during file upload!</span><br/><br/>';
      }

return true;

}

以下是位于文件名的单独页面（imageupload.php）上的php代码：

<?php

session_start();

if (isset($_POST['fileimagename'])) {

$_SESSION['fileimagename'] =  $_SESSION[' $_FILES['fileImage']['name']'];

}

if( file_exists("ImageFiles/".$_FILES['fileImage']['name'])) {
    $parts = explode(".",$_FILES['fileImage']['name']);
    $ext = array_pop($parts);
    $base = implode(".",$parts);
    $n = 2;

    while( file_exists("ImageFiles/".$base."_".$n.".".$ext)) $n++;
    $_FILES['fileImage']['name'] = $base."_".$n.".".$ext;

    move_uploaded_file($_FILES["fileImage"]["tmp_name"],
    "ImageFiles/" . $_FILES["fileImage"]["name"]);
    $result = 1;

}
    else
      {
      move_uploaded_file($_FILES["fileImage"]["tmp_name"],
      "ImageFiles/" . $_FILES["fileImage"]["name"]);
      $result = 1;

      }

?>

<script language="javascript" type="text/javascript">window.top.window.stopImageUpload(<?php echo $result;?>);</script>

看起来错误是说$fileimagename未设置。

var nameimagefile = <?php echo $fileimagename; ?>;

你需要定义$fileimagename

在某处QandATable.php，您应该有一个$fileimagename = $_SESSION['fileimagename'], 或设置该 var 的东西。
