Question

说明：- 它直接转到else部分，而不执行验证部分。我在autoload.php中添加了“ form_validation”库和“ form”帮助器。 Register.php包含视图部分。 Main_Controller.php包含功能user_register。我已经尝试了两种方式： 1. set_rules（） 2. form_validation.php（外部文件）

观看部分：

Answer 1

表单验证后的

重定向可清除验证错误。试试这个

if ($this->form_validation->run()) {
    echo "Registration Successfull";
} else {
    $this->session->set_flashdata('error', validation_errors());
    redirect('Main_Controller/register');
}

表单验证在Codeigniter中无法正常工作
