我從我的註冊控制器調用驗證碼模型。 「insert_captcha（）模型函數加載驗證碼助手，更新驗證碼錶，並將創建的驗證碼返回給顯示在視圖中的寄存器控制器驗證碼創建時Codeigniter驗證碼助手錯誤
它工作正常50％的時間，但我不時讓PHP錯誤的大名單：
提取模型：
class captcha_model extends CI_Model {
public function __construct() {
parent::__construct();
$this->load->helper('captcha');
}
public function insert_captcha() {
//captcha creation
$vals = array(
'img_path' => './captcha/',
'img_url' => base_url() . 'captcha',
'font_path' => './assets/fonts/OpenSans-Bold.ttf',
'img_width' => '150',
'img_height' => 30,
'expiration' => 900,
'word_length' => 8,
'font_size' => 16,
'img_id' => 'captcha-pic',
'pool' => 'abcdefghijklmnopqrstuvwxyz',
'colors' => array(
'background' => array(255, 255, 255),
'border' => array(255, 255, 255),
'text' => array(0, 0, 0),
'grid' => array(255, 40, 40)
)
);
$captcha = create_captcha($vals);
//insert captcha into DB
$captcha_db_params = array(
'captcha_time' => $captcha['time'],
'ip_address' => $this->input->ip_address(),
'word' => $captcha['word']
);
$query = $this->db->insert_string('captcha', $captcha_db_params);
if ($this->db->query($query)) { return $captcha; }
else { return false; }
}
}
提取控制器的
class Register extends CI_Controller {
public $data = array();
public function __construct() {
parent::__construct();
$this->load->model('captcha_model');
if ($this->session->userdata('logged_in')) {
$this->data['name'] = $this->session->userdata('name');
$this->data['id'] = $this->session->userdata('id');
$this->data['email'] = $this->session->userdata('email');
$this->data['isAdmin'] = $this->session->userdata('isAdmin');
}
if (!empty($this->session->flashdata('error'))) { $this->data['error'] = $this->session->flashdata('error'); }
}
public function index() {
//captcha creation success
if ($cap = $this->captcha_model->insert_captcha()) {
$this->data['title'] = 'Register';
$this->data['captcha'] = $cap;
$this->template->load('default', 'register/register', $this->data);
}
//not supposed to happen
else {
$this->data['error'] = 'Erreur systeme, captcha non genere';
$this->template->load('default', 'register/register', $this->data);
}
}
的錯誤
