Question

我在使用uploadify时遇到了问题。每当我在$ post_id中使用字符串时，uploadify只会在我选择3个文件进行上传时上传单个文件。但是当我为$ post_id指定一个不存在的值时，例如一个不存在的会话变量$ _SESSION ['something']。它将所有三个文件都插入到数据库中。我认为这可能是$ post_id的数据结构上的错误。

 if(!empty($_FILES)){
            $post_id = 'aa';
            $name2 = mysql_real_escape_string($_FILES['Filedata']['name']);
            $mime2 = mysql_real_escape_string($_FILES['Filedata']['type']);
            $data2 = mysql_real_escape_string(file_get_contents($_FILES['Filedata']['tmp_name']));
            $size2 = intval($_FILES['Filedata']['size']);



            $db->query("INSERT INTO tbl_files SET post_id='$post_id', filename='$name2', file_data='$data2', mime_type_id='$mime2'");



    }

我试图回显剩下的数据，看起来他们只存储普通的字符串。所以$ post_id字符串也应该有效，

echo $_FILES['Filedata']['name'];

Answer 1

如果您正在使用会话，请检查您是否已启动会话，即session_start（）

如果你想将post_id从uploadify函数传递给php文件，你可以使用scriptData，这在下面的函数中提到。

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
    $(document).ready(function(){
    //uploadify function
    $("#file_upload").uploadify({
        'uploader': 'uploadify.swf',
        'script': 'uploadify.php',
        'cancelImg': 'cancel.png',
        'folder': 'photos', //folder where images to be uploaded
        'auto': false, // use for auto upload
        'multi': true,
        'queueSizeLimit': 6,
        'buttonImg': 'images/upload.png',
        'width': '106',
        'height': '33',
        'wmode': 'transparent',
        'method': 'POST',
        'scriptData': {'myid':post_id}, //you can post the id here
        'onQueueFull': function(event, queueSizeLimit) {
            alert("Please don't put anymore files in me! You can upload " + queueSizeLimit + " files at once");
            return false;
        },
        'onComplete': function(event, ID, fileObj, response, data) {
            $("#uploadfiles").append(response+",");
        },
        'onAllComplete': function(response, data) {
            showAll();
        }
    });
</script>

<强> uploadify.php

if (!empty($_FILES)) {
    $post_id = $_POST['myid'];
    include_once "config.php";

    //use this when uploading images into a folder
    $tempFile = $_FILES['Filedata']['tmp_name'];

    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';

    $fna = $_FILES['Filedata']['name'];
    $targetFile =  str_replace('//','/',$targetPath) . $fna;
    move_uploaded_file($tempFile,$targetFile);
    //folder upload end

           $name2 = mysql_real_escape_string($_FILES['Filedata']['name']);
            $mime2 = mysql_real_escape_string($_FILES['Filedata']['type']);
            $data2 = mysql_real_escape_string(file_get_contents($_FILES['Filedata']['tmp_name']));
            $size2 = intval($_FILES['Filedata']['size']);



        $db->query("INSERT INTO tbl_files SET post_id='$post_id', filename='$name2', file_data='$data2', mime_type_id='$mime2'");

}

试试这个应该按预期工作

 $tblQry = 'INSERT INTO tbl_files ';
 $tblQry .= 'SET         
        post_id                 = "' .$_SESSION['post_id'] . '",
        filename                = "' .$name2. '",
        file_data               = "' .$data2.'",
        mime_type_id            = "' .$mime2.'"';
  $db->query($tblQry);

刚遇到这个问题。 Flash不使用浏览器中设置的cookie，因此您需要将会话ID作为post变量传递到Flash脚本中，然后在upload.php脚本中的post值中设置cookie值。参见：
