I don’t do it this way any longer, but the following might help you?
// Check if the file was uploaded successfully
if (isset($_FILES['image']) && $_FILES['image']['error'] === UPLOAD_ERR_OK) {
$uploadedFile = $_FILES['image'];
// Validate the file (e.g., file size, type, etc.)
$maxFileSize = 25 * 1024 * 1024; // 25 MB
$allowedFileTypes = ['image/jpeg', 'image/png'];
if ($uploadedFile['size'] > $maxFileSize) {
echo json_encode(['error' => 'File size is too large.']);
exit();
}
if (!in_array($uploadedFile['type'], $allowedFileTypes)) {
echo json_encode(['error' => 'Invalid file type.']);
exit();
}
// Move the uploaded file to the desired destination
$destinationDirectory = '../assets/canvas_images/';
$saveDirectory = '/assets/canvas_images/';
$destinationFilename = time() . '_' . basename($uploadedFile['name']);
$destinationPath = $destinationDirectory . $destinationFilename;
if (move_uploaded_file($uploadedFile['tmp_name'], $destinationPath)) {
// Load the image
$image = imagecreatefromjpeg($destinationPath);
// Get the original dimensions
$original_width = imagesx($image);
$original_height = imagesy($image);
// Calculate the new dimensions
$new_width = 1200;
$new_height = 800;
$scale = min($new_width / $original_width, $new_height / $original_height);
$width = intval($original_width * $scale);
$height = intval($original_height * $scale);
// Create a new image with the new dimensions
$new_image = imagecreatetruecolor($width, $height);
// Copy and resize the original image to the new image
imagecopyresampled($new_image, $image, 0, 0, 0, 0, $width, $height, $original_width, $original_height);
// Save the new image
imagejpeg($new_image, $destinationPath, 100);
$savePath = $saveDirectory . $destinationFilename;
// Prepare the SQL INSERT statement
$sql = "INSERT INTO lego_trivia (points, question, answer, canvas_images) VALUES (:points, :question, :answer, :canvas_images)";
$stmt = $pdo->prepare($sql);
// Bind the values to the placeholders
$stmt->bindValue(':points', $points, PDO::PARAM_INT);
$stmt->bindValue(':question', $question);
$stmt->bindValue(':answer', $answer);
$stmt->bindValue(':canvas_images', $savePath);
// Execute the prepared statement
$insertSuccess = $stmt->execute();
I do it this way now and find it much easier →
use Intervention\Image\ImageManagerStatic as Image;
// Check if the form was submitted with POST method
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// Get the input and textarea values
$category = $_POST['category'] ?? null;
$question = $_POST['question'] ?? null;
$answer = $_POST['answer'] ?? null;
$points = $_POST['points'] ?? null;
// Validate input and textarea values as needed
// ...
// Check if the file was uploaded successfully
if (isset($_FILES['image']) && $_FILES['image']['error'] === UPLOAD_ERR_OK) {
$uploadedFile = $_FILES['image'];
// Validate the file (e.g., file size, type, etc.)
$maxFileSize = 56 * 1024 * 1024; // 25 MB
$allowedFileTypes = ['image/jpeg', 'image/png'];
if ($uploadedFile['size'] > $maxFileSize) {
echo json_encode(['error' => 'File size is too large.']);
exit();
}
if (!in_array($uploadedFile['type'], $allowedFileTypes)) {
echo json_encode(['error' => 'Invalid file type.']);
exit();
}
// Move the uploaded file to the desired destination
$destinationDirectory = '../assets/canvas_images/';
$saveDirectory = '/assets/canvas_images/';
$destinationFilename = time() . '_' . basename($uploadedFile['name']);
$destinationPath = $destinationDirectory . $destinationFilename;
if (move_uploaded_file($uploadedFile['tmp_name'], $destinationPath)) {
// Load the image
$image = Image::make($destinationPath);
// Resize the image to a width of 1200 and constrain aspect ratio (auto height)
$image->resize(1200, null, function ($constraint) {
$constraint->aspectRatio();
});
// Save the resized image
$image->save($destinationPath);
$savePath = $saveDirectory . $destinationFilename;
// Prepare the SQL INSERT statement
$sql = "INSERT INTO canyousolve (points, question, answer, canvas_images, category) VALUES (:points, :question, :answer, :canvas_images, :category)";
$stmt = $pdo->prepare($sql);
// Bind the values to the placeholders
$stmt->bindValue(':points', $points, PDO::PARAM_INT);
$stmt->bindValue(':question', $question);
$stmt->bindValue(':answer', $answer);
$stmt->bindValue(':canvas_images', $savePath);
$stmt->bindParam(':category', $category);
// Execute the prepared statement
$insertSuccess = $stmt->execute();
I find using \ImageManagerStatic library is easier and a little more secure.
