我正在制作一个包含库存的小型系统。我有一个products表,该表具有一个image
列,该列代表特定产品的图片。我的问题是为什么我不能在Laravel项目中使用模态和Ajax代码上传?有谁知道如何解决这个问题?我已经花了两天的时间来解决该错误:
消息:“未定义索引:product_name”
我已经将字段填充到模型中。帮助将不胜感激。

当服务器需要JSON时,好像您向服务器发送了一个对象。尝试添加dataType:
$.ajax({
url: "{{ url('/product') }}",
method: 'post',
enctype: 'multipart/form-data',
contentType: false,
dataType: 'json', // setting of data type
data:{
product_name: name,
description: description,
price: price,
supplier_id: supplier_id,
image: image,
},
success: function (res) {
console.log(res);
window.location.href = '{{route("products")}}'
}
});

我知道这个问题已经很老了,但我在过去几天遇到了同样的问题,所以我认为一个答案可能对其他开发者有用。
您只需要使用 FormData 而不是序列化您的表单。请注意,FormData 需要一个 HTMLFormElement,因此您需要将 [0] 添加到您的 jQuery 对象。而且您不必添加 dataType 指令。
这是我的代码:
$('#submit').on('click', function(e) {
e.preventDefault();
$(this).attr('disabled','disabled');
var form = $(this).closest('form');
jQuery.ajax({
type: 'POST',
processData: false,
contentType: false,
data: new FormData(form[0]),
url: form.attr('action'),
enctype: 'multipart/form-data',
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
success: function (data) {
$('#submit').removeAttr('disabled');
// YOUR SUCCESS MANAGEMENT
},
error: function (e) {
$('#submit').removeAttr('disabled');
// YOUR ERROR MANAGEMENT
}
});
});
