Hello friends, welcome back to my blog. Today in this blog post, I am going to tell you, How to upload, preview and save image inside folder in react js?

Reactjs image upload and save

For reactjs new comers, please check the below link:

Reactjs Basic Tutorials


Friends here is the code snippet for How to upload, preview and save image inside folder in react js? and please use this code snippet carefully to avoid the mistakes:

1. Firstly friends we need fresh reactjs setup and for that we need to run below commands into our terminal and also w should have latest node version installed on our system:

npx create-react-app reactimageupload

cd reactimageupload

npm start // run the project

 

2. Now we need to run below commands to get bootstrap(for good layout), react image uploading(for image upload ) and axios(to post image request to php)  modules into our react js app:

npm install bootstrap --save

npm install --save react-images-uploading

npm install axios --save

npm start

 

3. Finally friends we need to add below code into our src/App.js file to get final output on web browser:

import React from 'react';
import './App.css';

//bootstrap
import 'bootstrap/dist/css/bootstrap.min.css';

//For Image Save
import axios from 'axios';

//For Image Upload
import ImageUploading from "react-images-uploading";


class App extends React.Component {
  onChange = (imageList) => {
    // data for submit
    
    // Create an object of formData 
    const formData = new FormData(); 
     
    // Update the formData object 
    formData.append( 
      "myFile", 
      imageList[0].file, 
      imageList[0].file.name
    ); 
   
    // Details of the uploaded file 
    console.log(imageList[0].file); 
   
    // Request made to the backend api 
    // Send formData object to my php file for save in folder
    axios.post("http://localhost/reactimageupload.php", formData); 
  }; 
   

  render() {
   
    return (
     
      <div className="maincontainer">
        
        <h1 className="mr-5 ml-5 mt-5">TheRichPost</h1>
        <div className="container mb-5 mt-5">
        
        <ImageUploading
        onChange={this.onChange}
      >
        {({ imageList, onImageUpload }) => (
          // write your building UI
          <div className="imageuploader">

            <div className="mainBtns">
            <button className="btn btn-primary mr-1" onClick={onImageUpload}>Upload Image</button>
            
            </div>
            {imageList.map((image) => (
              <div className="imagecontainer" key={image.key}>
                <img src={image.dataURL} />
                
              </div>
            ))}
          </div>
        )}
      </ImageUploading>

       
            
      </div>

      
      </div>
      
)
};
}

export default App;

 

4. In the end friends we need to add below code into our src/App.css file to style the things:

.imagecontainer {
  float: left;
  width: 215px;
  height: auto;
  margin: 10px 0;
}
.imagecontainer img{width: 150px; margin:10px 0;}
.imageuploader{width: 800px; height: 400px; background-color:#cbeefc;padding: 10px;}

 

5. For moving image inside folder, friends here is my php file reactimageupload.php code, which I have used in reactjs. I have put this file inside my xampp/htdocs folder and I have also made uploads folder into my xampp/htdocs folder:

Guys I have used php to move image inside the folder

<?php

//Upload folder
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["myFile"]["name"]);
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image

  $check = getimagesize($_FILES["myFile"]["tmp_name"]);
  if($check !== false) {

  //Move File To Uploads Folder
    if (move_uploaded_file($_FILES["myFile"]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES["myFile"]["name"]). " has been uploaded.";
    } else {
    echo "Sorry, there was an error uploading your file.";
    }
    
  } else {
    echo "File is not an image.";
    
  }


?>
