How to upload an image and display it using php and html?

Hi,

Ensure the images directory has the correct permissions to allow file uploads.
Make sure sessions are correctly started on every page where you access session variables.
Consider adding more error handling for better user experience.

Make sure your HTML form and image display code are set up properly.

Choose an image to upload:

PHP Code (upload_file.php)



";
        $uploadOk = 0;
    }
} else {
    die("No file was uploaded or invalid file input.");
}

// Check file size (optional)
if ($_FILES["profilePicture"]["size"] > 500000) {
    echo "Sorry, your file is too large.
";
    $uploadOk = 0;
}

// Allow certain file formats
if (!in_array($imageFileType, ["jpg", "jpeg", "png", "gif"])) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.
";
    $uploadOk = 0;
}

// Attempt to upload the file
if ($uploadOk == 1) {
    // Generate a unique filename for the uploaded image
    $targetFile = $targetDir . uniqid("profile_") . "." . $imageFileType;
    if (move_uploaded_file($_FILES["profilePicture"]["tmp_name"], $targetFile)) {
        // Store the filename in the session to remember the uploaded image
        $_SESSION['profile_image'] = $targetFile;
        echo "The file has been uploaded.
";
    } else {
        echo "Sorry, there was an error uploading your file.
";
    }
} else {
    echo "File upload failed.
";
}

// Redirect back to the dashboard (make sure to check where you want to go)
header("Location: dashboard-user.php");
exit();
