[Решено] Функция imagecreatefromjpeg возвращает пустое значение

Recommended Posts

Уважаемые разработчики, помогите решить проблему. В контроллере модуля Обратной связи в пользовательской части для капчи определена функция

function captcha() {
		$rand = time() + (mt_rand(0, time()));
		$ra = mt_rand(1, 10);
		$random = substr($rand, 1, $ra);
		$code = substr(hexdec(md5(date("F j").$random)), 2, 6);
		$this->session->data['pin'][$this->request->get['captcha_id']] = $code;
		$image = imagecreatefromjpeg(DIR_SYSTEM.'captcha/captcha.jpg');
		$color = imagecolorallocate($image, rand(50, 150), rand(50, 100), rand(50, 150));
		imagettftext($image, 14, rand(-3, 3), rand(5, 15), 18, $color, DIR_SYSTEM."captcha/x.ttf", $code);
			imagejpeg($image, "", 100);
		$data = base64_encode(ob_get_clean());
		echo $data;


На денвере работает прекрасно, на сервере ошибка imagejpeg(): Filename cannot be empty


Как понимаю, функция не успевает создать картинку.

В интернете нашла вот такое решение http://www.php.su/imagecreatefromjpeg

Но то ли я его реализую неправильно, то ли ошибка в другом месте. Не могу разобраться.

// Пропускаем параметр filename, используя NULL, а затем устанавливаем качество в 75%
imagejpeg($im, NULL, 75);
