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

Question

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?

Answer 1

The API provides component for this purpose.
<Button
variant="contained"
component="label"
>
Upload File
<input
type="file"
hidden
/>
</Button>

Answer 2

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>

Answer 3

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>

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);

Answer 5

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>

Answer 6

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>
);

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
</Button>
</label>
<label htmlFor="icon-button-file">
<Input accept="image/*" id="icon-button-file" type="file" />
<IconButton color="primary" aria-label="upload picture" component="span">
<PhotoCamera />
</IconButton>
</label>
</Stack>
);
}

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) => {

Answer 9

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>

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>

Answer 11

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>

Answer 12

<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.

Answer 13

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>
)

Answer 14

Typescript version of #tomatentobi's javascript solution
const uploadInputRef = useRef<HTMLInputElement | null>(null);
return (
<>
<input
ref={uploadInputRef}
type="file"
accept="image/*"
style={{ display: "none" }}
onChange={onChange}
/>
<Button
onClick={() => uploadInputRef.current && uploadInputRef.current.click()}
variant="contained">
Upload
</Button>
</>
);

Answer 15

This worked for me.
<Button variant="contained" component="label" >
UPLOAD
<input accept="image/*" hidden type="file" />
</Button>

Answer 16

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" />

Answer 17

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();

Answer 18

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)

Answer 19

Or there is library for MUI 5 / React 18 : https://viclafouch.github.io/mui-file-input/ 🔥
import React from 'react'
import { MuiFileInput } from 'mui-file-input'
const MyComponent = () => {
const [value, setValue] = React.useState(null)
const handleChange = (newValue) => {
setValue(newValue)
}
return <MuiFileInput value={value} onChange={handleChange} />
}

Answer 20

Try This
import React from 'react'
import { MuiFileInput } from 'mui-file-input'
export default function MyComponent () {
const [file, setFile] = React.useState(null)
const handleChange = (newFile) => {
setFile(newFile)
}
return (
<MuiFileInput value={file} onChange={handleChange} />
)
}
npm install mui-file-input --save
npm install #mui/icons-material
or
yarn add mui-file-input
yarn add #mui/icons-material

Answer 21

another way is this and we can add the name of the file as a value for TextField.
<TextField
value={state.value}
label="upload profile picture"
sx={{ m: 1, width: '25ch' }}
InputProps={{
fullWidth: true,
startAdornment: (
<IconButton component="label">
<AttachFileIcon />
<input
type="file"
hidden
onChange={handleUploadInput}
name="[name]"
/>
</IconButton>
)
}}
/>
