我写了一小段代码,它应该适用于Codeigniter中的验证码.代码应该只是简单地打印验证码创建的时间,首先尝试.但它似乎甚至没有创建验证码本身.我确定帮助器被加载,这是在构造函数中完成的.除此之外,将图像写入文件夹的正确权限应该在那里.任何人都知道为什么它不工作,因为它应该？
- defined('BASEPATH') OR exit('No direct script access allowed');
- class Register extends CI_Controller{
- public function __construct(){
- parent::__construct();
- $this->load->helper('captcha');
- }
- public function generate_captcha(){
- $vals = array(
- 'img_path' => './captcha/','img_url' => base_url().'captcha/',);
- echo base_url().'assets/images/captcha/';
- $captcha = create_captcha($vals);
- echo 'cap time: ' . $captcha['time'];
- $captcha_image = $captcha['image'];
- return $captcha_image;
- }
- }
- <?PHP defined('BASEPATH') OR exit('No direct script access allowed');
- class Mycaptcha extends CI_Controller {
- public function __construct() {
- parent::__construct();
- $this->load->helper('captcha');
- $this->load->helper('url');
- }
- public function index() {
- $vals = array(
- 'img_path' => './captcha/','img_url' => base_url().'/captcha/',);
- $captcha = create_captcha($vals);
- $captcha_image = $captcha['image'];
- print_r($captcha);
- }
- }
确保你有：
>在根目录下创建文件夹captcha,权限为777>在config.PHP $config [‘base_url’] =’http：// localhost / yourproject /’;
