Uploading Files with Ease: Using FilePond with PHP Forms
Tired of clunky file upload forms? Want a user-friendly and modern approach to file handling in your PHP applications? Enter FilePond, a JavaScript library that revolutionizes file uploads, offering a seamless experience for your users.
The Problem: Traditional file upload forms often lack the polish and interactivity users expect. They can be cumbersome, lacking progress indicators or drag-and-drop functionality, leading to frustration and abandonment.
The Solution: FilePond brings modern web development to file uploads, enabling users to easily select, drag-and-drop, and upload files directly within a web form. This article will guide you through integrating FilePond with your PHP forms, enabling efficient file handling and seamless user experience.
Scenario: Imagine a simple form allowing users to upload an image, such as a profile picture for a website. With FilePond, the user can simply drag-and-drop their image into the form or browse their files, with real-time progress indicators showing the upload status.
Original Code (PHP):
<form method="POST" enctype="multipart/form-data">
<input type="file" name="image" id="image">
<button type="submit">Upload</button>
</form>

PHP (upload.php):
<?php
// Handle file upload
if (isset($_FILES['image'])) {
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["image"]["name"]);
$uploadOk = 1;
// Check file type
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["image"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["image"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Upload file
if ($uploadOk == 1) {
if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
