How to Implement an Upload Progress Bar in PHP

Are you working on a photo album uploader and seeking to display a progress bar during the upload process? This article provides a concise solution for adding a progress bar to your PHP upload script.

PHP Upload Progress Bar Solution

Instead of creating a custom progress bar solution from scratch, we recommend utilizing the Fine Uploader library. This library offers several advantages:

• Simplicity: It's easy to set up and integrate into your PHP script.
• Wide Compatibility: It works well on shared hosting environments without requiring external PHP libraries like APC.
• Progress Feedback: It provides real-time progress updates for each file being uploaded.
• Advanced Features: It supports HTML5 drag-and-drop functionality and multiple file uploads.

Implementing Fine Uploader

To implement Fine Uploader in your script:

1. Visit the GitHub page: https://github.com/FineUploader/fine-uploader
2. Download the library and extract it into your web server's directory.
3. Include the following line in your script after including your PHP file:

<script src="path_to_fine_uploader/jquery.fine-uploader.js"></script>

4. Initialize the uploader with custom options:

<script>
$(document).ready(function() {
    $('#fine-uploader').fineUploader({
        request: {
            endpoint: 'path_to_your_upload_script.php'
        },
        validation: {
            sizeLimit: 102400000 // in bytes (100 Mb)
        },
        callbacks: {
            onUpload: function(id, fileName) {
                console.log('Upload started for:', fileName);
            },
            onProgress: function(id, fileName, uploadedBytes, totalBytes) {
                var progress = Math.round(100 * uploadedBytes / totalBytes);
                console.log('Progress:', fileName, progress + '%');
            },
            onComplete: function(id, fileName, responseJSON) {
                console.log('Upload completed:', fileName);
            }
        }
    });
});
</script>
