HTML CSS PHP File Upload With Circle Progress Bar

Creating a file upload feature with a circular progress bar involves multiple steps. You’ll need to use HTML, CSS, JavaScript (to handle the progress bar), and PHP (to process the file upload on the server). Here’s a basic example of how to achieve this.

Step-by-Step Implementation

1. HTML: Create the file upload form



    
    
    File Upload with Progress Bar
    


    
        
            
            
        
        
            0%

2. CSS: Style the progress bar

/* styles.css */body {
    font-family: Arial, sans-serif;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
    background-color: #f4f4f4;
    margin: 0;
}

.upload-container {
    text-align: center;
}

.progress-circle {
    width: 100px;
    height: 100px;
    border-radius: 50%;
    background: conic-gradient(#4caf50 0% 0%, #e0e0e0 0% 100%);
    display: flex;
    justify-content: center;
    align-items: center;
    margin: 20px auto;
}

.progress-text {
    font-size: 1.5em;
    font-weight: bold;
    color: #4caf50;
}

3. JavaScript: Handle the file upload and progress

// script.js
document.getElementById('uploadForm').addEventListener('submit', function(e) {
    e.preventDefault();

    let formData = new FormData();
    let fileInput = document.getElementById('fileInput');
    formData.append('file', fileInput.files[0]);

    let xhr = new XMLHttpRequest();
    xhr.open('POST', 'upload.php', true);

    xhr.upload.addEventListener('progress', function(e) {
        if (e.lengthComputable) {
            let percentComplete = Math.round((e.loaded / e.total) * 100);
            updateProgressBar(percentComplete);
        }
    });

    xhr.onreadystatechange = function() {
        if (xhr.readyState == 4 && xhr.status == 200) {
            document.getElementById('uploadStatus').innerText = 'Upload complete!';
        }
    };

    xhr.send(formData);
});

function updateProgressBar(percent) {
    let circle = document.getElementById('progressCircle');
    let text = document.getElementById('progressText');

    circle.style.background = `conic-gradient(#4caf50 ${percent}%, #e0e0e0 ${percent}% 100%)`;
    text.innerText = `${percent}%`;
}

4. PHP: Handle the file upload on the server

How It Works

HTML: The form allows users to select a file and submit it. The circular progress bar is displayed with an initial value of 0%.
CSS: Styles the circular progress bar using a conic-gradient.
JavaScript: Listens for the form submission, handles the file upload using XMLHttpRequest, and updates the progress bar as the upload progresses.
PHP: Processes the uploaded file on the server, saving it to the specified directory.

This is a basic implementation. Depending on your needs, you might want to add more features such as:

File validation
Error handling
Additional styles
Security measures (e.g., restricting file types, size limits)

Ensure your server’s configuration allows for file uploads and is properly secured to prevent potential vulnerabilities.
