Upload multiple file with vue js and axios - laravel

Question

I am trying to upload multiple images using vuejs and axios but on server side i am getting empty object. I added multipart/form-data in header but still empty object.
submitFiles() {
/*
Initialize the form data
*/
let formData = new FormData();
/*
Iteate over any file sent over appending the files
to the form data.
*/
for( var i = 0; i < this.files.length; i++ ){
let file = this.files[i];
console.log(file);
formData.append('files[' + i + ']', file);
}
/*`enter code here`
Make the request to the POST /file-drag-drop URL
*/
axios.post( '/fileupload',
formData,
{
headers: {
'Content-Type': 'multipart/form-data'
},
}
).then(function(){
})
.catch(function(){
});
},
HTML:
<form method="post" action="#" id="" enctype="multipart/form-data">
<div class="form-group files text-center" ref="fileform">
<input type="file" multiple="multiple">
<span id='val'></span>
<a class="btn" #click="submitFiles()" id='button'>Upload Photo</a>
<h6>DRAG & DROP FILE HERE</h6>
</div>
My Server side code:
class FileSettingsController extends Controller
{
public function upload(Request $request){
return $request->all();
}
}
Output:
{files: [{}]}
files: [{}]
0: {}
Console.log() result:
File(2838972) {name: "540340.jpg", lastModified: 1525262356769, lastModifiedDate: Wed May 02 2018 17:29:16 GMT+0530 (India Standard Time), webkitRelativePath: "", size: 2838972, …}

Answer 1

You forgot to use $refs. Add ref to your input:
<input type="file" ref="file" multiple="multiple">
Next, access your files like this:
submitFiles() {
const formData = new FormData();
for (var i = 0; i < this.$refs.file.files.length; i++ ){
let file = this.$refs.file.files[i];
formData.append('files[' + i + ']', file);
}
axios.post('/fileupload', formData, {
headers: {
'Content-Type': 'multipart/form-data'
},
}
).then(function(){
})
.catch(function(){
});
},
This should be works.

If anyone wondering, "How can I send also data with it", there you go:
formData.append('name[' + this.name + ']', name);
formData.getAll('files', 'name');

Answer 3

For Composition API this should work:
const files = ref([])
function save() {
let formData = new FormData()
for (let file of files.value) {
formData.append('files', file)
}
axios.post('/upload', formData, {
headers: {
'Content-Type': 'multipart/form-data',
},
})
.then((response) => {
})
}
