The PHP notice "Undefined index: images" means the script tried to read $_FILES['images'] but that array key does not exist. In 's case the most common root causes are a name mismatch between the HTML input and the PHP key, the form not being submitted as a multipart POST, the user submitting the form without choosing a file, or PHP rejecting the upload (so $_FILES is empty). Start by confirming what the server actually received.

Quick, reliable checks to add at the top of the upload handler:

var_dump($_SERVER['REQUEST_METHOD'], $_FILES);
if (!isset($_FILES['images']) || $_FILES['images']['error'] !== UPLOAD_ERR_OK) {
    // handle missing upload or inspect the error code
}

If $_FILES is empty after a submit, check php.ini limits (upload_max_filesize, post_max_size) and that the target directory exists and is writable. Use the UPLOADERR constants to get the exact failure reason (see the file-upload errors doc). Always validate and sanitize file names (do not trust client names), check move_uploaded_file() return values, and keep error reporting on while debugging.

As a longer-term fix: avoid mixing mysql and mysqli, migrate to mysqli or PDO with prepared statements, and enable detailed errors during development (error_reporting(E_ALL); ini_set('display_errors',1);). For authoritative details see the PHP file upload documentation: Handling file uploads - Manual and $_FILES - Manual.
