php - cakephp 从 db 获取数据

Question

我是 cakephp 新手，如何在 cakephp 中编写下面的 sql 查询

$sql = "SELECT * FROM `user` WHERE `email` = '" . $email . "' AND  `password` = '" . $password . "'";

$result = mysql_query($sql, $connection);

while($fetchdata = mysql_fetch_assoc($result)){
    echo $fetchdata['name'];
}

请帮助我谢谢

Answer 1

在您的用户控制器中，您可以执行以下操作：

$this->set('user',$this->User->find('all', array ('conditions' => array('email' => $email, 'password' => $password))));

在你看来

foreach ($user as $us) {
   echo($us['name']);
//your code
}

Answer 3

对于您的查询：

<?php

 $this->loadmodel('User');
 $result = $this->User->find('first',array('conditions' => array('email' => $email,  
 'password' => $password)));
 foreach($result as $row)
 {
   //do whatever you want to do

 }
?>

Answer 4

使用 cakephpfind方法来做到这一点。

<?php

    $users = $this->User->find('first',array
    (
        'conditions' => array
        (
            'User.email'    => $email,
            'User.password' => $password
        )
    ));

    pr($users);
    exit;

?>

我已添加pr($users);exit;用于调试查询结果。

您还可以通过recursive,limit等order以及 find 方法find在cakephp上阅读更多信息

Answer 5

如果您在用户控制器中，则无需加载模型并连接数据库。如果您从另一个模型访问用户模型，则将您的用户模型加载到您的控制器中。您可以通过两种方式加载模型

$this->loadmodel('User');
or
public $uses = array('User');
$results = $this->User->find('all',array('conditions' => array('email' => $email,'password' => $password)));
$this->set(compact('results '));

现在在你的视图文件中使用这个

foreach ($results as $users) {
  echo h($users['User']['email']);
  echo h($users['User']['password']);
}
