提交具有相同名称的多个输入 [英] Submitting multiple inputs with same name

问题描述

好的，所以我有创建民意调查的表格。我想使用AJAX请求和能够用户附加图像而不是问题，所以我使用FormData。

Ok, so I have form for creating polls. I want to use AJAX request and able user to attach image instead of question, so I use FormData for this.

我无法找到任何解决方案来处理多个输入同名（命名如下：name []）。我尝试了这个选项：

I could't find any solution for working with multiple input with same name (named like this: "name[]"). I tried this option:

var fdata = new FormData();
fdata.append('answers[]', $('input[name="answer[]"]').val());

但它不起作用。我知道我可以使用 .each（），但我不希望每个问题有不同的名称，所以我不必太多地重建PHP方面。

But it doesn't work. I know I could use .each(), but I don't want different name for each question, so I don't have to rebuild PHP side too much.

感谢您的帮助。

推荐答案

您必须附加每个值转。目前你只追加第一个（因为那是 val（）返回。

You have to append each value in turn. Currently you are only appending the first one (because that is what val() returns.

$('input[name="answer[]"]').each(function (index, member) {
    var value = $(member).val();
    fdata.append('answers[]', value);
});
