标签: ajax codeigniter

嗨,我是ajax的新手,有问题。我正在尝试使用ajax制作购物车。我不知道我的代码有什么问题请帮帮我。 当我点击添加按钮时,会发出警告“没有成功”#39;没有任何事情发生,我无法将商品添加到购物车。 谢谢你的帮助。

这是我的观点

server {
    listen      80;
    server_name www.my-app.com;
    return 301  $http_x_forwarded_proto://my-app.com$request_uri;
}

这是我的控制器

类Shopping2扩展了CI_Controller {

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

请帮助我如何使用ajax在购物车中添加商品。

答案 0 :(得分:0)

由于您设法得到回复,问题应该出在您的模型或数据插入中。

很少有建议:

  1. 还建议您使用$ .post()而不是$ .ajax()。
  2. "<?php echo base_url(); ?>" + "index.php/shopping2/add"可以更改为"<?php echo site_url('shopping2/add"'); ?>"
  3. 使用内置的Codeignter输出类输出您的JSON。见这里:https://www.codeigniter.com/userguide3/libraries/output.html
