我正在尝试检索上传文件的名称并将其附加到 .list 中。问题是它从 $_SESSION 变量中检索的文件名始终是最后更新的文件,然后它不会改变。

例如,如果我在服务器中上传以下这些文件:

desert.jpg
tulips.jpg
lighthouse.jpg
desert_2.jpg

那么它应该从 $_SESSION 附加的文件名应该是:

desert.jpg
tulips.jpg
lighthouse.jpg
desert_2.jpg

但相反,它在屏幕上为从 $_SESSION 检索到的文件名附加了以下内容:

desert.jpg
desert.jpg
desert.jpg
desert.jpg

如何解决这个问题,以便在将文件上传到服务器时,将其文件名附加到 .list 上?

下面是 $_SESSION 变量在 json 代码中的 javascript 函数,它通过将文件名附加到 .list 上来在屏幕上显示文件名:

  function stopImageUpload(success){

          var imagename = <?php echo json_encode(isset($_SESSION ['fileImage']['name']) ? $_SESSION ['fileImage']['name'] : null); ?>;
          if (success == 1){
             $('.listImage').append(imagename + '<br/>');
          }
          else {

            $('.listImage').append('No File');
          }

    return true;

    }

下面是它上传文件的php代码:

<?php

session_start();

$result = 0;
$errors = array ();
$dirImage = "ImageFiles/";

$allowedTypes = array (
        "image/jpeg",
        "image/gif",
        "image/pjpeg",
        "image/jpg",
        "image/png",
        "image/tif" 
);

if (isset ( $_FILES ['fileImage'] ) && $_FILES ["fileImage"] ["error"] == UPLOAD_ERR_OK) {

    $fileName = $_FILES ['fileImage'] ['name'];
    $fileSize = $_FILES ['fileImage'] ['size'];
    $fileTemp = $_FILES ['fileImage'] ['tmp_name'];
    $fileType = $_FILES ['fileImage'] ['type'];

    $fileExt = pathinfo ( $fileName, PATHINFO_EXTENSION );
    $fileExt = strtolower ( $fileExt );

    if (empty ( $fileName ))
        continue;

    if (! in_array ( $fileType, $allowedTypes )) {
        $errors [] = "File Type is not accepted";

    }

    if(!is_writable($dirImage ))
    {
        $errors [] = "File Destination not writeable";
    }


    $fileDst = $dirImage . DIRECTORY_SEPARATOR . $fileName;
    $filePrifix = basename ( $fileName, "." . $fileExt );
    $i = 0;
    while ( file_exists ( $fileDst ) ) {
        $i ++;
        $fileDst = $dirImage . DIRECTORY_SEPARATOR . $filePrifix . "_" . $i . "." . $fileExt;

    }
    // Move the file

    if (count ( $errors ) == 0) {
        if (move_uploaded_file ( $fileTemp, $fileDst )) {
            $result = 1;


        }
    }

}

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

?>

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

在单独的页面上,我有一个检索 $_SESSION 的 JSON:

function stopImageUpload(success){

      var imagename = <?php echo json_encode(isset($_SESSION ['fileImage']) ? $_SESSION ['fileImage'] : null); ?>;
      if (success == 1){
         $('.listImage').append(imagename + '<br/>');
      }
      else {
        $('.listImage').append('<br/>');
      }

return true;

}

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