文件上传&使用Uploadify上传进度

时间:2013-01-18 06:42:44

标签: php jquery file-upload progress-bar uploadify

我创建了一个动态下拉文件上传系统,用户可以选择工程流,然后是学期,然后是主题,并将文件上传到所需目录。这通常很好。 Working example检查文件路径链接,在不同文件夹中将图像或文档两次上传三次以查看其变化情况。

然后我想显示文件上传进度,所以我下载并开始使用此uploadify。并遇到了以下问题。

这里有两个问题: 1)当我点击选择文件并选择文件时,文件上传,但我找不到任何地方但我已经设置了targetFolder 2)我想首先选择路径,然后选择文件,然后单击上传(如exmaple中所示)然后我希望它上传到我从下拉列表中选择的指定目录中。

这是我的代码:

    <!DOCTYPE html>
<html lang="en">
    <head>
        <meta http-equiv="content-type" content="text/html; charset=UTF-8">
        <title> SRMUARD - Upload </title>
        <link rel="stylesheet" type="text/css" href="uploadify.css" />
        <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
        <script type="text/javascript" src="jquery.uploadify-3.1.min.js"></script>  
        <script type="text/javascript">
            $(function() {
                $('#file_upload').uploadify({
                    'swf'      : 'uploadify.swf',
                    'uploader' : 'uploadify.php',
                    'progressData' : 'speed',
                    'folder': <?php echo $targetFolder; ?>
                });
            });
        </script>
        <script type="text/javascript">
            function val()
            {
                if(document.uploads.three.selectedIndex == 0)
                {
                    alert("Please choose all the appropriate options");
                }
            }
        </script>   
        <script>
            $(function() {
                $("#text-one").change(function() {
                $("#text-two").load("textdata/" + $(this).val() + ".txt");
                });
                $("#text-two").change(function() {
                $("#text-three").load("textdata/" + $(this).val() + ".txt");
                });
            });
         </script>

    </head>
    <body>
        <div>
            <form action="uploadify.php" method="POST" enctype="multipart/form-data" name="upload" id="upload">
                <label for="file">Choose a file: </label><br/>

                    <select id="text-one" name="one">                   
                        <option selected value="base">Select Department</option>
                        <option value="CSE" name="cse">Computer Science Engineering</option>
                        <option value="ECE" name="ece">Electronics & Communication Engineering</option>
                        <option value="MECH" name="mech">Mechanical Engineering</option>                        
                    </select><br/><br/> 
                    <select id="text-two" name="two">
                        <option>Select Semester</option> //Displays options dynamically using text files
                    </select><br/><br/>                 
                    <select id="text-three" name="three">
                        <option>Select Subject</option> //Displays options dynamically using text files
                    </select><br/><br>  
                    <input type="file" name="file_upload" id="file_upload" ><br/><br/>  
                    <input type="submit" name="upload" id="submit" value="Upload" onClick="val()" />        
            </form>
        <div>
    </body>
</html>

这是我的uploadify.php文件:

    <?php

    if(isset($_POST['upload']))  //checking if the path is set
   { 
      $path1=$_POST['one']."/"; //path1
      $path2=$_POST['two']."/"; //path2
      $path3=$_POST['three']."/";   //path3
      $targetFolder=$path1.$path2.$path3; //final path without the file
   }
   else
   {
      echo "Select a Subject";
      echo "<br>";
   }


if (!empty($_FILES)) {
    $tempFile = $_FILES['file_upload']['tmp_name'];
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
    $targetFile = rtrim($targetPath,'/') . '/' . $_FILES['file_upload']['name'];
    // Validate the file type
    $fileTypes = array('jpg','jpeg','gif','png'); // File extensions
    $fileParts = pathinfo($_FILES['file_upload']['name']);
    if (in_array($fileParts['extension'],$fileTypes)) {
        move_uploaded_file($tempFile,$targetFile);
        echo $targetFolder . '/' . $_FILES['file_upload']['name'];
    } else {
        echo 'Invalid file type.';
    } 
?>

请帮我解决这个问题并让我显示进度条并将其上传到正确的目标文件夹。

谢谢

答案 0 :(得分:0)

此广告'uploadify'上传文件之前您已选择表单元素。您可以在参数'formData'中添加数据,如下所示:

$(function() {
var one = $('#text-one').val();
var two = $('#text-two').val();
var one = $('#text-three').val();
$('#file_upload').uploadify({
'swf' : 'uploadify.swf',
'uploader' : 'uploadify.php',
'progressData' : 'speed',
'formData': {'one':one,'two':'two','three':three},
'folder': 
});
});

答案将在“onUploadComplete”

事件中出现
