POST file along with form data Vue + axios

Question

I have a method for Vuejs component:

async submit () {
        if (this.$refs.form.validate()) {
          let formData = new FormData()
          formData.a         


        

Answer 1

So, I figured this one out in a simpler way:

    let rawData = {
                name: this.name,
                gender: this.gender,
                dob: this.dob
              }
              rawData = JSON.stringify(rawData)
    let formData = new FormData()
          formData.append('avatar', this.avatarFile, this.avatarFile.name)
          formData.append('data', rawData)
    try {
            let response = await this.$axios.post('http://localhost:3003/api/test.php', formData, {
              headers: {
                'Content-Type': 'multipart/form-data'
              }
         })

test.php:

$_POST = json_decode($_POST['data'],true);

Note: I had an option of using:

Object.keys(rawData).map(e => {
            formData.append(e, rawData[e])
          })

but since I was dealing with nested objects (name: { first: '', last: ''} ) in rawData, I chose not to do that as it would require recursive methods on either client side or server side.

PHP ( process.php )

<?php
    $data = array(
        "post"  => $_POST,
        "files" => $_FILES
    );

    echo json_encode($data);
?>

Vue and form HTML

let vm = new Vue({
    el: "#myApp",
    data: {
        form: {}
    },
    methods: {
        submit: async function (e) {
            e.preventDefault();

            /* formData */
            var formData = new FormData( this.$refs.formHTML );

            /* AJAX request */
            await axios({
                method: "post",
                url: "process.php",

                data: formData,

                config: { headers: { "Content-Type": "multipart/form-data" } }
            })

            /* handle success */
            .then( response => { console.log(response.data); } )

            /* handle error */
            .catch( response => { console.log(response) } );
        }
    }
});
