How to enable file upload on React's Material UI simple input?

ReactjsElectronReact ReduxRedux FormFormsy Material-Ui

Reactjs Problem Overview

I am creating a simple form to upload file using electron-react-boilerplate with redux form & material ui.

The problem is that I do not know how to create input file field because material ui does not support upload file input.

Any ideas on how to achieve this?

Reactjs Solutions

Solution 1 - Reactjs

The API provides component for this purpose.

<Button
  variant="contained"
  component="label"
>
  Upload File
  <input
    type="file"
    hidden
  />
</Button>

Solution 2 - Reactjs

newer MUI version:

<input
  accept="image/*"
  className={classes.input}
  style={{ display: 'none' }}
  id="raised-button-file"
  multiple
  type="file"
/>
<label htmlFor="raised-button-file">
  <Button variant="raised" component="span" className={classes.button}>
    Upload
  </Button>
</label>

Solution 3 - Reactjs

You need to wrap your input with component, and add containerElement property with value 'label' ...

<RaisedButton
   containerElement='label' // <-- Just add me!
   label='My Label'>
   <input type="file" />
</RaisedButton>

You can read more about it in this GitHub issue.

EDIT: Update 2019.

Check at the bottom answer from @galki

TLDR;

<input
  accept="image/*"
  className={classes.input}
  style={{ display: 'none' }}
  id="raised-button-file"
  multiple
  type="file"
/>
<label htmlFor="raised-button-file">
  <Button variant="raised" component="span" className={classes.button}>
    Upload
  </Button>
</label>

Solution 4 - Reactjs

Here's an example using an IconButton to capture input (photo/video capture) using v3.9.2:

import React, { Component, Fragment } from 'react';
import PropTypes from 'prop-types';

import { withStyles } from '@material-ui/core/styles';
import IconButton from '@material-ui/core/IconButton';
import PhotoCamera from '@material-ui/icons/PhotoCamera';
import Videocam from '@material-ui/icons/Videocam';

const styles = (theme) => ({
    input: {
        display: 'none'
    }
});

class MediaCapture extends Component {
    static propTypes = {
        classes: PropTypes.object.isRequired
    };

    state: {
        images: [],
        videos: []
    };

    handleCapture = ({ target }) => {
        const fileReader = new FileReader();
        const name = target.accept.includes('image') ? 'images' : 'videos';

        fileReader.readAsDataURL(target.files[0]);
        fileReader.onload = (e) => {
            this.setState((prevState) => ({
                [name]: [...prevState[name], e.target.result]
            }));
        };
    };

    render() {
        const { classes } = this.props;

        return (
            <Fragment>
                <input
                    accept="image/*"
                    className={classes.input}
                    id="icon-button-photo"
                    onChange={this.handleCapture}
                    type="file"
                />
                <label htmlFor="icon-button-photo">
                    <IconButton color="primary" component="span">
                        <PhotoCamera />
                    </IconButton>
                </label>

                <input
                    accept="video/*"
                    capture="camcorder"
                    className={classes.input}
                    id="icon-button-video"
                    onChange={this.handleCapture}
                    type="file"
                />
                <label htmlFor="icon-button-video">
                    <IconButton color="primary" component="span">
                        <Videocam />
                    </IconButton>
                </label>
            </Fragment>
        );
    }
}

export default withStyles(styles, { withTheme: true })(MediaCapture);

Solution 5 - Reactjs

It is work for me ("@material-ui/core": "^4.3.1"):

    <Fragment>
        <input
          color="primary"
          accept="image/*"
          type="file"
          onChange={onChange}
          id="icon-button-file"
          style={{ display: 'none', }}
        />
        <label htmlFor="icon-button-file">
          <Button
            variant="contained"
            component="span"
            className={classes.button}
            size="large"
            color="primary"
          >
            <ImageIcon className={classes.extendedIcon} />
          </Button>
        </label>
      </Fragment>

Solution 6 - Reactjs

If you're using React function components, and you don't like to work with labels or IDs, you can also use a reference.

const uploadInputRef = useRef(null);

return (
  <Fragment>
    <input
      ref={uploadInputRef}
      type="file"
      accept="image/*"
      style={{ display: "none" }}
      onChange={onChange}
    />
    <Button
      onClick={() => uploadInputRef.current && uploadInputRef.current.click()}
      variant="contained"
    >
      Upload
    </Button>
  </Fragment>
);

With Material-UI and React Hooks

import * as React from "react";
import {
  Button,
  IconButton,
  Tooltip,
  makeStyles,
  Theme,
} from "@material-ui/core";
import { PhotoCamera } from "@material-ui/icons";

const useStyles = makeStyles((theme: Theme) => ({
  root: {
    "& > *": {
      margin: theme.spacing(1),
    },
  },
  input: {
    display: "none",
  },
  faceImage: {
    color: theme.palette.primary.light,
  },
}));

interface FormProps {
  saveFace: any; //(fileName:Blob) => Promise<void>, // callback taking a string and then dispatching a store actions
}

export const FaceForm: React.FunctionComponent<FormProps> = ({ saveFace }) => {

  const classes = useStyles();
  const [selectedFile, setSelectedFile] = React.useState(null);

  const handleCapture = ({ target }: any) => {
    setSelectedFile(target.files[0]);
  };

  const handleSubmit = () => {

Official recommendation

import * as React from 'react';
import { styled } from '@mui/material/styles';
import Button from '@mui/material/Button';
import IconButton from '@mui/material/IconButton';
import PhotoCamera from '@mui/icons-material/PhotoCamera';
import Stack from '@mui/material/Stack';

const Input = styled('input')({
  display: 'none',
});

export default function UploadButtons() {
  return (
    <Stack direction="row" alignItems="center" spacing={2}>
      <label htmlFor="contained-button-file">
        <Input accept="image/*" id="contained-button-file" multiple type="file" />
        <Button variant="contained" component="span">
          Upload

You can use Material UI's Input and InputLabel components. Here's an example if you were using them to input spreadsheet files.

import { Input, InputLabel } from "@material-ui/core";

const styles = {
  hidden: {
    display: "none",
  },
  importLabel: {
    color: "black",
  },
};

<InputLabel htmlFor="import-button" style={styles.importLabel}>
    <Input
        id="import-button"
        inputProps={{
          accept:
            ".csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel",
        }}
        onChange={onInputChange}
        style={styles.hidden}
        type="file"
    />
    Import Spreadsheet
</InputLabel>

Solution 10 - Reactjs

Just the same as what should be but change the button component to be label like so

<form id='uploadForm'
      action='http://localhost:8000/upload'
      method='post'
      encType="multipart/form-data">
    <input type="file" id="sampleFile" style="display: none;" />
    <Button htmlFor="sampleFile" component="label" type={'submit'}>Upload</Button> 
</form>

Solution 11 - Reactjs

<input type="file"
               id="fileUploadButton"
               style={{ display: 'none' }}
               onChange={onFileChange}
        />
        <label htmlFor={'fileUploadButton'}>
          <Button
            color="secondary"
            className={classes.btnUpload}
            variant="contained"
            component="span"
            startIcon={
              <SvgIcon fontSize="small">
                <UploadIcon />
              </SvgIcon>
            }
          >

            Upload
          </Button>
        </label>

Make sure Button has component="span", that helped me.

Solution 12 - Reactjs

Here an example:

return (
    <Box alignItems='center' display='flex' justifyContent='center' flexDirection='column'>
      <Box>
        <input accept="image/*" id="upload-company-logo" type='file' hidden />
        <label htmlFor="upload-company-logo">
          <Button component="span" >
            <Paper elevation={5}>
              <Avatar src={formik.values.logo} className={classes.avatar} variant='rounded' />
            </Paper>
          </Button>
        </label>
      </Box>
    </Box>
  )

Solution 13 - Reactjs

 import AddPhotoIcon from "@mui/icons-material/AddAPhoto";
 import Fab from "@mui/material/Fab";

  <Fab color="primary" aria-label="add-image" sx={{ position: "fixed", bottom: 16, right: 16, overflow: "hidden" }}>
    <input
      type="file"
      onChange={imageHandler}
      accept=".jpg, .jpeg, .png"
      accept="image/*"
      multiple
      style={{ //make this hidden and display only the icon
        position: "absolute", 
        top: "-35px",
        left: 0,
        height: "calc(100% + 36px)",
        width: "calc(100% + 5px)",
        outline: "none",
      }}
    />

    <AddPhotoIcon />
  </Fab>

Solution 14 - Reactjs

You can pursue all the comments above, those are really great, However, I have another option for customizing your component, if you want to follow.

// Import

import { styled } from '@mui/material/styles';
import { Input } from "@mui/material";

// Custom style

const CustomFileInput = styled(Input)(({ theme }) => {
  return {
    color: "white",
    '::before': {
      border: 'none',
      position: 'static',
      content: 'none'
    },
    '::after': {
      border: 'none',
      position: 'static',
      content: 'none'
    }
  }
});

// Using that component

<CustomFileInput type="file" />

Solution 15 - Reactjs

Both @galki and @elijahcarrel method works fine. If anyone trying to do unit-testing(jest) for these two answers.

You wont be able to use the button component with (specially if you are using disabled=true

expect(getByRole("button", {name: "Upload"})).not.toBeEnabled();

instead use this

expect(getByLabelText("Upload")).not.toBeEnabled();

Solution 16 - Reactjs

This is for Select Image File

<IconButton color="primary" component="label">
   <input type="file" accept="image/*" hidden />
   <AttachFileIcon fontSize="medium" />
</IconButton>

NOTE : React Material UI Component (IconButton, AttachFileIcon)
