Upload Image in Vue Component with Laravel - laravel-5

Question

I am making a simple website that has a feature to upload images. I tried it Laravel way which I made it in blade template and it works fine. Now I am trying to make it inside Vue Components
Here's my Create.vue
<template>
<div>
<div class="row">
<input type="hidden" name="_token" :value="csrf">
<div class="col-md-5">
<div class="detail-container">
<label for="title">Book Title:</label>
<input type="text" name="title" id="title" v-model="book_title" class="form-control">
</div>
<div class="detail-container">
<label for="title">Book Description:</label>
<textarea type="text" name="description" id="description" v-model="book_description" class="form-control" rows="5"></textarea>
</div>
<div class="detail-container">
<label for="title">Tags:</label>
<multiselect v-model="tags" :show-labels="false" name="selected_tags" :hide-selected="true" tag-placeholder="Add this as new tag" placeholder="Search or add a tag" label="name" track-by="id" :options="tagsObject" :multiple="true" :taggable="true" #tag="addTag" #input="selectTags">
<template slot="selection" slot-scope="tags"></template>
</multiselect>
</div>
</div>
<div class="col-md-7">
<!-- BOOK COVER WILL GO HERE -->
<div class="detail-container">
<label>Book Cover:</label>
<input type="file" class="form-control-file" id="book_cover" name="selected_cover" #change="onFileChange">
<small id="fileHelp" class="form-text text-muted">After you select your desired cover, it will show the preview of the photo below.</small>
<div id="preview">
<img v-if="url" :src="url" height="281" width="180" />
</div>
</div>
</div>
<div class="detail-container" style="margin-top: 20px;">
<button class="btn btn-primary" #click="saveBook()">Next</button>
</div>
</div>
</div>
</template>
<script>
import Multiselect from 'vue-multiselect'
// register globally
Vue.component('multiselect', Multiselect)
export default {
// OR register locally
components: { Multiselect },
data () {
return {
csrf: document.querySelector('meta[name="csrf-token"]').getAttribute('content'),
url: null,
selected_cover: null,
tags: [],
tagsObject: [],
selected_tags: [],
book_title: '',
book_description: ''
}
},
methods: {
getTags() {
let vm = this;
axios.get('/admin/getTags').then(function(result){
let data = result.data;
for(let i in data) {
vm.tagsObject.push({id: data[i].id, name: data[i].name});
}
});
},
addTag (newTag) {
const tag = {
name: newTag,
id: newTag.substring(0, 2) + Math.floor((Math.random() * 10000000))
}
this.tagsObject.push(tag);
this.tags.push(tag);
},
selectTags(value) {
this.selected_tags = value.map(a=>a.id);
},
onFileChange(e) {
const file = e.target.files[0];
this.url = URL.createObjectURL(file);
this.selected_cover = file;
},
saveBook() {
const fd = new FormData();
fd.append('image', this.selected_cover, this.selected_cover.name)
console.log(this.selected_cover);
var book_details = {
'title': this.book_title,
'description': this.book_description,
'book_cover': this.selected_cover,
'tags': this.selected_tags
};
axios.post('/admin/saveBook', book_details).then(function(result){
console.log('done')
})
}
},
created() {
this.getTags();
}
}
</script>
<!-- New step!
Add Multiselect CSS. Can be added as a static asset or inside a component. -->
<style src="vue-multiselect/dist/vue-multiselect.min.css"></style>
and here's my controller
public function store(Request $request)
{
$this->validate(request(), [
'title' => 'required|min:5',
'description' => 'required|min:10',
'book_cover' => 'required|image|mimes:jpeg,jpg,png|max:10000'
]);
// File Upload
if($request->hasFile('book_cover')) {
$fileNameWithExt = $request->file('book_cover')->getClientOriginalName();
// GET FILE NAME
$filename = pathinfo($fileNameWithExt, PATHINFO_FILENAME);
// GET EXTENSION
$extension = $request->file('book_cover')->getClientOriginalExtension();
// File Unique Name
$fileNameToStore = $filename. '_'. time().'.'.$extension;
$path = $request->file('book_cover')->storeAs('public/book_covers', $fileNameToStore);
} else {
$fileNameToStore = 'noimage.jpg';
}
$book = new Book;
$book->title = request('title');
$book->description = request('description');
$book->book_cover = $fileNameToStore;
$book->save();
$book->tags()->sync($request->tags, false);
return back()->with('success', 'Book Created Successfully!');
}
I never touched my controller because this is what I used when I do this feature in Laravel Way but when I save it, the details are being saved but the image is not uploading instead it saves noimage.jpg in the database. Does anyone know what I am doing wrong?
i tried to add this part const fd = new FormData(); in book_details but when i console.log(fd) it returned no data.

Answer 1

you should pass the fd object and not the book_details in your POST request.
you could do it something like this.
onFileChange(e) {
const file = e.target.files[0];
// this.url = URL.createObjectURL(file);
this.selected_cover = file;
},
saveBook() {
const fd = new FormData();
fd.append('image', this.selected_cover)
fd.append('title', this.book_title)
fd.append('description', this.book_description)
fd.append('book_cover', URL.createObjectURL(this.selected_cover))
fd.append('tags', this.selected_tags)
axios.post('/admin/saveBook', fd).then(function(result){
console.log('done')
})
}
and also, you can't just console.log the fd in the console. what you can do instead is something like this
for (var pair of fd.entries()) {
console.log(pair[0]+ ', ' + pair[1]);
}
FormData is a special type of object which is not stringifyable and cannot just be printed out using console.log. (link)
