我正在尝试使用jquery和php上传包含图像的表单 - 数据已保存，但图像未上传，并且ajax调用运行错误函数，而不是成功函数。
即使有文件从php文件中回显，在jQuery中它似乎只是一个对象的.text值未定义...
这些是php错误日志中的错误消息：

我无法解决问题所在。提前谢谢。
我的jQuery代码是：
$("#signUpOrganizationForm").submit(function(){
//var organizationFormData = $(this).serialize();
//data to be sent to server (serialize doesn't work for files, so instead we are manually created FormData. Alternatively you can use the Jquery Form Plugin.
var organizationFormData = new FormData();
organizationFormData.append( "profilepic", $('#profilepic')[0].files[0]);
organizationFormData.append( "orgName", $('#orgName').val());
organizationFormData.append( "Username", $('#Username').val());
organizationFormData.append( "Password", $('#Password').val());
//e.preventDefault();
$.ajax({
url: "php/signuporganization.php", //Relative or absolute path to response.php file
type: "POST",
data: organizationFormData,
contentType: false,
processData: false,
dataType:'json',
success: function(data) {
// data = JSON.parse(data);
console.log(data);
alert('Hello we are here and data return = ' + data);
localStorage.id = data;
console.log('localStorage = ' + localStorage.id);
$.mobile.changePage($('#home-organization'),'pop');
},
error: function(data, status, error) {
//data = JSON.parse(data)
alert('error:' + data.text);
}
});

我认为在获得profilepic的第一行的PHP脚本中应该是$ _FILES而不是$ _File。

我发现这是跨源资源共享（CORS）中的一个问题。我通过put header（'Access-Control-Allow-Origin：*'）来解决它;在php文件中。显然，这不是一个很好的生产选择，但这只是测试。另外，filepath是相对的，所以我不得不在php文件夹中创建uploads文件夹，最后，我必须将返回的数据编码为JSON对象。
