I am posting here as a beginner of VueJS and Laravel. I am stuck with a problem that I can't fix by myself after hours of search.

I would like to know how correctly send and get back the inputs of a form (complex data and files).

Here is the submit method of the form:

```
onSubmit: function () {
  var formData = new FormData();
  formData.append("data", this.model.data);
  formData.append("partData", this.model.partData);
  if (this.model.symbolFile != null) {
    formData.append("symbolFile", this.model.symbolFile);
  }
  if (this.model.footprintFile != null) {
    formData.append("footprintFile", this.model.footprintFile);
  }
  axios
    .post("/api/updatecomponent", formData, {
      headers: {
        "Content-Type": "multipart/form-data",
      },
    })
    .then((res) => {
      // do something with res
      // console.log(res);
    })
    .catch((err) => {
      /* catch error*/
      console.log(err);
    });
},

```

The variable Data and PartData contains multiple string fields which will be stored in different tables in my database. Example :
Data
{
string Value,
string Tolerance,
string Power
}

Here is the method of the Controller in the server side:

```
public function updateComponent(Request $req)
{
   $data = $req->input('data');
   $partData = $req->input('partData');
   $symbolFile = $req->file('symbolFile'); // is null if the user did not modify the symbol
   $footprintFile = $req->file('symbolFile'); // is null if the user did not modify the footprint
   // etc...
}

```

I am able to get the files, everything work for that and I can store and read them :)

But, the problem is that I am unable to get back properly my Data or PartDat.
When I do :

```
dd($partData);

```

I got as result in the console:

```
"[object Object]"

```

I am almost sure that I don't use correctly the FormData but after hours of search, I can't find the good way I should gave the Data and PartData to the FormData.

My code was working well for Data and PartData until I add FormData to support the file upload :(

Thank you for your help :)
