codeigniter

如何检查数据库中的数据是否为真不在CodeIgniter中使用会话,codeigniter,Codeigniter,我正在使用CodeIgniter，我有一个函数可以将电子邮件地址和代码插入数据库我现在希望用户发布该代码，如果它是正确的，删除它，如果它是不正确的，让用户再试一次我已经编辑了原始编码电子邮件控制器-我删除了对会话的引用，并注释掉了发送电子邮件的内容，因为我只在localhost中进行测试。电子邮件功能运行良好。发布电子邮件功能后，我打开数据库并复制必须正确的代码代码控制器-我已删除对会话的引用。我现在在代码视图中有一个电子邮件文本框，顺便说一句，它会自动插入电子邮件地址。然后我将代码粘贴

我正在使用CodeIgniter，我有一个函数可以将电子邮件地址和代码插入数据库

我现在希望用户发布该代码，如果它是正确的，删除它，如果它是不正确的，让用户再试一次

我已经编辑了原始编码

电子邮件控制器-我删除了对会话的引用，并注释掉了发送电子邮件的内容，因为我只在localhost中进行测试。电子邮件功能运行良好。发布电子邮件功能后，我打开数据库并复制必须正确的代码

代码控制器-我已删除对会话的引用。我现在在代码视图中有一个电子邮件文本框，顺便说一句，它会自动插入电子邮件地址。然后我将代码粘贴到“代码”文本框中

但是，尽管代码是正确的，但选择的是视图（'code不正确'），而不是视图（'username'）

谁能告诉我怎么了

电子邮件控制器

代码模型

class Code_model extends CI_Model
{
function __construct()
{
parent::__construct();
$this->load->database();
}
public function find_code($email, $code)
{
$this->db->select('user_id');
$this->db->where('email_address', $email);
$this->db->where('pass_word', $code);
$code = $this->db->get('tbl_members');
if ($code->result())
{
return $this->db->delete('pass_word', $code);
}
}
}

这是代码视图中的编码，可能导致问题

<style type="text/css"> .email-address { position: fixed; width: 100%; text-align: center; top: 30%; } </style>
<div class="email-address">
<input type="text" name="email" value="<?php echo set_value('email'); ?>" style="width: 18%; height: 5mm"; />
<style type="text/css"> .code { position: fixed; width: 100%; text-align: center; top: 55%; } </style>
<div class="code">
<input type="email" class="form-control" name="code" style="width: 15mm; height: 5mm"; />
<a href="<?php echo BASE_URL . 'username'; ?>"></a></div>
<?php echo form_open('code'); ?>
<style type="text/css"> .submit { position: fixed; width: 100%; text-align: center; top: 65%; } </style>
<div class="submit">
<input type="submit" class="btn btn-primary" value="Submit" />
</form></div>

。电子邮件地址{位置：固定；宽度：100%；文本对齐：居中；顶部：30%；}
因此，您的控制器正确调用模型，但您没有检查模型功能，也没有发送电子邮件字段
所以这应该是正确的：
控制器：
public function index()
{
    $this->load->model('Code_model', 'code_model');
    $code = $this->input->post('code');
    $email= $this->input->post('email');

    if ($this->code_model->find_code($code, $email)) {
        $this->load->view('username');
    } else {
        $this->load->view('codeincorrect');
    }

}

public function find_code($code, $email)
{
    $this->db->select('user_id');
    $this->db->where('email_address', $email);
    $this->db->where('pass_word', $code);
    $code = $this->db->get('tbl_members')->result();
    if ($code->num_rows() >= 1) {
        $this->db->delete('pass_word', $code);
    }

}

型号：
public function index()
{
    $this->load->model('Code_model', 'code_model');
    $code = $this->input->post('code');
    $email= $this->input->post('email');

    if ($this->code_model->find_code($code, $email)) {
        $this->load->view('username');
    } else {
        $this->load->view('codeincorrect');
    }

}

public function find_code($code, $email)
{
    $this->db->select('user_id');
    $this->db->where('email_address', $email);
    $this->db->where('pass_word', $code);
    $code = $this->db->get('tbl_members')->result();
    if ($code->num_rows() >= 1) {
        $this->db->delete('pass_word', $code);
    }

}

注意：
如果您尝试的是密码登录，那么您不应该这样做。请查看此示例：

谢谢Jewel Mia博士，我尝试过你建议的改变，但出现了这个错误；遇到未捕获的异常类型：错误消息：调用未定义的函数form_open（）文件名：C:\xampp\htdocs\application\views\codeError.php，该文件在视图中引用此文件；以上与我所做的其他函数一起工作$此->加载->查看（'code不正确'）；鉴于，代码是正确的，应转到$此->加载->查看（'username'）；该视图是用户名和密码的下一步。它无法工作，因为它加载$this->load->View（'code不正确'）；是的，因为如果不响应$result中的值，则加载$this->load->view（'code不正确'）；如果响应值在$result中，则加载$this->load->view（'username'）；您想让我检查什么来找到响应值？谢谢Web先生，我已经尝试了您建议的更改，但出现了此错误；遇到未捕获的异常类型：ParseError消息：语法错误，意外的文件结尾，预期函数（T_函数）引用它$此->数据库->删除（'pass_word'，$code）；在模型中。作为对您的查询的响应，不，我不尝试使用密码登录。我试图首先让用户发布一个电子邮件地址，我成功地将电子邮件地址和代码插入到数据库中。我想发送一封带有代码的电子邮件，但这将不得不等到我有了服务器。但是，我可以从数据库中复制代码，然后通过subject函数发布。代码只是暂时保存在pass_word字段中。下一步$this->load->view（'username'）；是永久用户名和密码。好的，但我现在得到这个错误；类型：错误消息：调用数组文件名：C:\xampp\htdocs\application\models\Code\u model.php上的成员函数num\u rows（），该函数表示if（$Code->num\u rows（）>=1）{I will will moother。
