Js代码

var form = document.forms.namedItem（“form-create-event”）;     的console.log（形式）;

form.addEventListener('submit', function(ev) 
{

  oData = new FormData(form);
  oData.append("seances", seance);

  console.log(oData);

  var oReq = new XMLHttpRequest();
  oReq.open("POST", form.action, true);
  oReq.onload = function(oEvent) {
    if (oReq.status == 200) {
      console.log('success');
    } else {

        console.log('failed');

    }
  };

  oReq.send(oData);
  ev.preventDefault();
}, false);

php code

公共功能商店（请求$请求）     {        return response（） - ＆gt; json（$ request-＆gt; all（））;

}

===========================================

我的问题是：

当我尝试（dd（$ request-＆gt; event_document））返回空对象

header request

Server response

Answer 1

很可能您正在尝试上传大于php.ini允许的大小的文件。所以在你的php.ini中设置upload_max_filesize和post_max_size的值：

上传文件的最大允许大小。

upload_max_filesize = 10M或您需要的任何尺寸

必须大于或等于upload_max_filesize

post_max_size = 10M
