I'm using vuetify components for front-end in Vuejs. I want to create a user registeration form with file upload. I'm able to create a form using v-text-field in vuetify but how to upload the file. Which component to use or any other alternative way.

Answer 1

This is something we will add in the future, but not currently. There is discussion on github with several users posting their implementations that they are using for the time being, https://github.com/vuetifyjs/vuetify/issues/238

Answer 2

An easy trick is:

<v-btn color="success" @click="$refs.inputUpload.click()">Success</v-btn>
<input v-show="false" ref="inputUpload" type="file" @change="yourFunction" >

Just create an input with the following properties:

• type=file
• ref=inputUpload this works like an id, you could name it like you want
• v-show=false this hides input

Then make a button that when you click it, it fires a click event on the input Upload Button.

Answer 3

Good news.

Starting with version 2.0.0.-beta.8 v-file-input is available in Vuetify. You're supposed to use it like:

<template>
  <v-file-input accept=".txt" label="Select File..."></v-file-input>
</template>

EDIT (SNIPPET ADDITION):

A basic usage for handling an image file can be implemented as follows.

Thanks to @Begueradj pointing there is even no need for handling @change event for tracking the file change and making the example even more precise:

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data: () => ({
    file: null,
    imageUrl: null
  }),
  methods: {
    onUpload() {
      console.log(this.file)
    }
  }
})

          label="Select Image File..." 
          accept="image/*"
        ></v-file-input>
        <v-btn color="primary" @click="onUpload">Upload</v-btn>
      </v-container>
    </v-content>
  </v-app>
</div>

Vue JS do not have file-input feature till today, so you can tweak v-text-field to work like image input field. The concept is, create an file input field and then hide it using css, and add an event in v-text-field to trigger that specific file input field to upload image. I have attached snippet please do play with that, and I also do have a fiddle created using vue and vuetify, visit here. Thanks!

new Vue({
    el: '#app',
    data: () => ({
        title: "Image Upload",
        dialog: false,
		imageName: '',
		imageUrl: '',
		imageFile: ''
    }),

    methods: {
        pickFile () {
            this.$refs.image.click ()
        },
		
		onFilePicked (e) {
			const files = e.target.files
			if(files[0] !== undefined) {
				this.imageName = files[0].name
				if(this.imageName.lastIndexOf('.') <= 0) {
					return
				}
				const fr = new FileReader ()
				fr.readAsDataURL(files[0])
				fr.addEventListener('load', () => {
					this.imageUrl = fr.result
					this.imageFile = files[0] // this is an image file that can be sent to server...
				})
			} else {
				this.imageName = ''
				this.imageFile = ''
				this.imageUrl = ''
			}
		}
    }

})
