Question

我对循环不是很好，但我想循环遍历数组中的每个会话文件值。如何在这种情况下编写foreach循环并将其放入php脚本或javascript代码中？

下面是上传文件的完整php脚本：

<?php

session_start();

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


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

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

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


    $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>

以下是包含json代码的javascript函数：

function stopImageUpload(success){

      var imageNameArray = <?php echo json_encode(isset($_SESSION ['fileImage']) ? $_SESSION ['fileImage'] : null); ?>;
      var result = '';



      if (success == 1){
         result = '<span class="msg">The file was uploaded successfully!</span><br/><br/>';
            for (imagename in imageNameArray)
    {
         $('.listImage').append(imagename + '<br/>');

     }

      }
      else {
         result = '<span class="emsg">There was an error during file upload!</span><br/><br/>';
      }

      $(sourceImageForm).find('.imagef1_upload_process').css('visibility','hidden');
      $(sourceImageForm).find('.imagef1_cancel').css('visibility','hidden');

      $(".sbtnimage").removeAttr("disabled");
      $(".sbtnvideo").removeAttr("disabled");
      $(".sbtnaudio").removeAttr("disabled");


      return true;   
}

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

把它放在PHP代码末尾附近。

var imageNameArray = <?php echo json_encode(isset($_SESSION ['fileImage']) ? $_SESSION ['fileImage'] : null); ?>;

将您的Javascript imagename更改为该内容。

然后循环：

for (imagename in imageNameArray)
{
    if (success == 1)
    {
         result = '<span class="msg">The file was uploaded successfully!</span><br/><br/>';
         $('.listImage').append(imagename + '<br/>');
      }
      else {
         result = '<span class="emsg">There was an error during file upload!</span><br/><br/>';
      }
}
