我尝试了一个简单的帖子值传递给另一个形式，这是互联网上的例子。所有这些都有效，但是当我尝试在我自己的表单上实现时，它确实工作......我也尝试使用会话。但是没有运气..有人可以帮助我..这是我的第一个表单代码..表单用于使用AJAX上传多个文件，并通过upload.php将其他信息保存到mysql，其中post值应该去。 / p>
index.php - 上传表单
<form action="upload.php" method="post" enctype="multipart/form-data">

if (isset($cat) and strlen($cat) > 0) {
$quer = "SELECT DISTINCT subcategory FROM subcategory where cat_id=$cat order by subcategory";
} else {
$quer="SELECT DISTINCT subcategory FROM subcategory order by subcategory";

答案 0 :(得分：0)
我不确定你明白你做了什么。您在页面加载后立即调用uploadFile函数。
对我来说，你必须用from加载页面，然后用户将在他的电脑上选择一些文件，然后他将提交表格，你必须上传他的文件。所以你必须在表单提交上调用函数uploadFile，但不像你那样。
您需要以下代码中的内容。
jQuery的：
$(document).ready(function()
{
$(document).on('submit','form#formId',function() {
var settings = {
url: "upload.php",
method: "POST",
allowedTypes:"jpg,jpeg,png,bmp,gif,mp3,mp4,avi,mpeg,flv,wmv,3gp,txt,doc,docx,ppt,pdf,zip,rar",
fileName: "myfile",
multiple: true,
onSuccess:function(files,data,xhr)
{
$("#status").html("<font color='green'></font>");
},
onError: function(files,status,errMsg)
{
$("#status").html("<font color='red'>Failed.</font>");
}
}
$("#mulitplefileuploader").uploadFile(settings);
}
});
在HTML中，您必须在表单中添加id属性：
<form action="upload.php" id='formId' method="post" enctype="multipart/form-data">
