Here’s a basic example of how you can implement file upload and download with a progress bar using PHP, JavaScript, and AJAX.
1. HTML Form for Upload
Create an index.html file with the following content:
Upload File
" style="position: relative; display: block; border: 1px solid var(--cib-color-stroke-neutral-primary); border-radius: var(--cib-border-radius-large); clear: both; margin-top: 12px; margin-block: 24px 12px;">HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>File Upload with Progress Bar</title>
<style>
#progress-bar {
width: 0;
height: 20px;
background-color: green;
}
</style>
</head>
<body>
<h2>Upload File</h2>
<form id="uploadForm" enctype="multipart/form-data">
<input type="file" name="file" id="file"><br><br>
<input type="submit" value="Upload">
</form>
<div id="progress-container">
<div id="progress-bar"></div>
</div>
<div id="uploadStatus"></div>
<script>
document.getElementById('uploadForm').onsubmit = function(event) {
event.preventDefault();
var formData = new FormData(this);
var xhr = new XMLHttpRequest();
xhr.open('POST', 'upload.php', true);
xhr.upload.onprogress = function(event) {
if (event.lengthComputable) {
var percentComplete = (event.loaded / event.total) * 100;
document.getElementById('progress-bar').style.width = percentComplete + '%';
}
};
xhr.onload = function( ) {
if (xhr.status == 200) {
document.getElementById('uploadStatus').innerHTML = 'File uploaded successfully!';
} else {
document.getElementById('uploadStatus').innerHTML = 'File upload failed!';
}
};
xhr.send(formData);
};
</script>
</body>
</html>
