我试图找回一个文件上载的名字,并将其输入名单上。 问题是,从“SESSION”变量中检索的档案名称始终是最新档案,然后是没有变化的。

例如,如果我把这些档案上载到服务器以下的话:

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

然后,它应从_SESSION美元中填写的档案名称应为:

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

但是,在从屏幕上的“SESSION”美元中检索的文档名称方面,下文对此作了评估:

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

如何确定,以便在档案上上载到服务器时,其档案名称被附在名单上?

下面是“javascript”功能,即“SESSION”变量在“json”代码中,显示屏幕上文档的名称,将其贴上:

  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;

    }

The Below is the php Code where it uploads the file:

<?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>

在适当网页上,有1名初等干事,可检索到_SESSION:

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;

}
