我的页面中有4个uploadify按钮。这是我的代码：
$(function() {
$('#file_upload').uploadify({
'formData' : {
'PHPSESSID': '<?=session_id()?>',
'timestamp' : '<?php echo $timestamp;?>',
'token' : '<?php echo md5('unique_salt' . $timestamp);?>'
},
'swf' : 'uploadify.swf',
'uploader' : 'uploadify.php?id=<? echo $resID; ?>&state=<? echo strtolower($negeri); ?>',
'onQueueComplete': function() {
setTimeout(function(){location.reload(true);},100)
}
});
$('#file_upload1').uploadify({
'formData' : {
'PHPSESSID': '<?=session_id()?>',
'timestamp' : '<?php echo $timestamp;?>',
'token' : '<?php echo md5('unique_salt' . $timestamp);?>'
},
'swf' : 'uploadify.swf',
'uploader' : 'uploadify1.php?id=<? echo $resID; ?>&state=<? echo strtolower($negeri); ?>',
'onQueueComplete': function() {
setTimeout(function(){location.reload(true);},100)
}
});
$('#file_upload2').uploadify({
'formData' : {
'PHPSESSID': '<?=session_id()?>',
'timestamp' : '<?php echo $timestamp;?>',
'token' : '<?php echo md5('unique_salt' . $timestamp);?>'
},
'swf' : 'uploadify.swf',
'uploader' : 'uploadify2.php?id=<? echo $resID; ?>&state=<? echo strtolower($negeri); ?>',
'onQueueComplete': function() {
setTimeout(function(){location.reload(true);},100)
}
});
$('#file_upload3').uploadify({
'formData' : {
'PHPSESSID': '<?=session_id()?>',
'timestamp' : '<?php echo $timestamp;?>',
'token' : '<?php echo md5('unique_salt' . $timestamp);?>'
},
'swf' : 'uploadify.swf',
'uploader' : 'uploadify3.php?id=<? echo $resID; ?>&state=<? echo strtolower($negeri); ?>',
'onQueueComplete': function() {
setTimeout(function(){location.reload(true);},100)
}
});
});
问题是它正在摧毁我的SESSION数据。当我删除3个其他的脚本。它并没有破坏我的会话。所以，我决定在页面中的所有4 uploadify按钮上使用一个脚本。我试过这样做：
$('.file_upload').uploadify({
'formData' : {
'PHPSESSID': '<?=session_id()?>',
'timestamp' : '<?php echo $timestamp;?>',
'token' : '<?php echo md5('unique_salt' . $timestamp);?>'
},
'swf' : 'uploadify.swf',
'uploader' : 'uploadify.php?id=<? echo $resID; ?>&state=<? echo strtolower($negeri); ?>',
'onQueueComplete': function() {
setTimeout(function(){location.reload(true);},100)
}
});
即便如此：
$(".file_upload").each(function() {
$(this).uploadify({
'formData' : {
'PHPSESSID': '<?=session_id()?>',
'timestamp' : '<?php echo $timestamp;?>',
'token' : '<?php echo md5('unique_salt' . $timestamp);?>'
},
'swf' : 'uploadify.swf',
'uploader' : 'uploadify.php?id=<? echo $resID; ?>&state=<? echo strtolower($negeri); ?>',
'onQueueComplete': function() {
setTimeout(function(){location.reload(true);},100)
}
});
});
但他们两个都行不通。该按钮不会出现。
有什么办法可以解决吗？
谢谢你：D。非常感谢您的帮助

你是否从official doc开始。我是关于：
formData : { '<?php echo session_name();?>' : '<?php echo session_id();?>' }
并在uploadify.php
$session_name = session_name(); if (!isset($_POST[$session_name])) { exit; } else { session_id($_POST[$session_name]); session_start(); }
答案 1 :(得分：2)
$('.selectorClass').uploadify({
formData:{
PHPSESSID: '<?=session_id()?>',
timestamp: '<?php echo $timestamp;?>',
token : '<?php echo md5('unique_salt' . $timestamp);?>'
},
swf : 'uploadify.swf',
uploader : 'uploadify.php?id=<? echo $resID; ?>&state=<? echo strtolower($negeri); ?>',
onQueueComplete: function() {
setTimeout(function(){location.reload(true);},100)
}
});
在查看uplodify的源代码之后，我发现传递给uplodify的对象没有像这样的单引号的键
var settings = $.extend({
// Required Settings
id : $this.attr('id'), // The ID of the DOM object
swf : 'uploadify.swf', // The path to the uploadify SWF file

preventCaching : true, // Adds a random value to the Flash URL to prevent caching of it (conflicts with existing parameters)
progressData : 'percentage', // ('percentage' or 'speed') Data to show in the queue item during a file upload

}, options);
这可能是你的问题背后的原因，试试这个，删除侧面json键的单引号。
