How to store file in laravel PHP - php

Question

Language used : js with react - redux-toolkit and php with laravel
I'm trying to save my file in my mongodb database
first of all, here my input file and axios function to post from client (react) to server(laravel) . (it's working, i received the data in php)
import React from 'react';
export const Attach = ({ register, setValue }) => {
const handleFile = (e) => {
setValue('Attachment', e.target.files[0]);
};
return (
<div >
<label >Insert a file </label>
<input type="file" name="file" onChange={(e) => handleFile(e)} />
</div>
);
};
and my axios post function
export const postOffers = (data) => (dispatch) => {
axios({
method: 'post',
url: `${process.env.REACT_APP_API_URL}offer`,
data: {
Type: Type,
UserName: data.UserName,
Object: data.Object,
Address: data.Address,
Comment: data.Comment,
Attachment: data.Attachment,
},
}).then((res) => {
if (!res.data) {
console.log('error form');
} else {
console.log(data.Attachment);
}
});
};
-> console.log(data.Attachment);
then in my php controller :
public function createOffers(Request $request)
{
if ($request) {
//what i have tried
//upload file
$bucket = InternOffer::getMongoDB()->selectGridFSBucket();
$file = $request->file('Attachment');
$resource = fopen($file, "a+");
$file_id = $bucket->uploadFromStream($file, $resource);
$InternOffer = InternOffer::create([
'Type' => $request->get('Type'),
"UserName" => $request->get('UserName'),
'Object' => $request->get('Object'),
'Address' => $request->get('Address'),
'Comment' => $request->get('Comment'),
// 'Attachment' => $file_id, (working if i don't pass the attachment)
]);
if ($InternOffer) {
$InternOffer->save();
return ["result" => "Offers has been successfully created"];
} else {
return ["result" => "failed"];
}
}
}
