我正在尝试使用jQuery将数据发送到后端。如果我控制台记录formdata，那么我会看到9个字段及其值。但是在应该接收数据的php页面中，我在执行var_dump时只看到3个字段。php页面上没有其他代码。
下面是我的jQuery AJAX 调用：
$(document).on("click", "#disputeReturnBtn", function () {
if ($("#rrn").val() == "") {
alert("RRN cannot be empty");
}
if (!$("input[name='dispute']:checked").val()) {
alert("Please choose a step");
}
var disputeform = document.getElementById("disputeForm");
var formData = new FormData(disputeform);
console.log(formData);
$.ajax({
type: "POST",
url: "../../form/scans.php",
data: formData,
contentType: false,
cache: false,
processData: false,
success: function (response) {
disputeform.reset();
console.log(response);
},
error: function (error) {
console.log(error);
},
});
});为什么我只看到三个字段的数据，而formdata有9个字段？原因是数据没有插入到数据库中，因为不是所有的字段都在那里。
我 AJAX 调用错误吗？

你们中的许多输入都有一个
id属性，但是没有name属性。当然，他们需要一个name属性才能在POST中显示。例如，替换：

问题1
注意，上传的文件不会显示在
$_POST中，而是显示在$_FILES中，并且在PHP中的处理方式不同。进一步调试
此外，尝试打开网络跟踪，以进行POST，它使用browser's developer tools。通常打开按下F12，然后转到网络选项卡。
