如何让控制器

Question

从模型和显示值我提出在笨站点，这里是我的控制器，模型和视图：

控制器：

function checking() 
{ 
$email=$this->input->post('email'); 
$this->load->model('login_model'); 
$data['dbemail']=$this->login_model->email();// assign your value to CI variable 
$this->load->view('home', $data); //passing your value to view 
} 

型号：

public function email() 
{ 
    $query = $this->db->query("SELECT email FROM change_password"); 
    $result = $query->result_array(); 
    return $result; 
} 

视图：

foreach ($dbemail as $new_dbemail) 
    { 
     echo $new_dbemail['database_field'];//in here you can get your table header. 
    //Ex if your table has name field and you need to sho it you can use $new_dbemail['name'] 
    } 

但我想在我的控制器中获得$ new_dbemail ['name']，我如何获得控制器中的$ new_dbemail ['name']的值而不是视图？

Answer 1

您呼叫的模式在一个变量： -

$data['dbemail']=$this->login_model->email(); 

所以在这你有你是从数据库中获取结果。比你传递这个变量数据到你的视图。

$this->load->view('home', $data); 

因此，您已经在控制器中获得了从存储在$ data中的模型中获取的值。

可以查看$数据中的值，使用

echo "<pre>"; 
print_r($data); 

，它会告诉你正在接受

Answer 2

什么数据尝试像这样...

在控制器...

function checking() 
{ 
$email=$this->input->post('email'); 
$this->load->model('login_model'); 
$dbemail=$this->login_model->email();//array containing all emails 
//For each loop here for displaying emails 
foreach($dbemail as $email){ 
    $mail = $email; //assigning to variable 
    echo $mail."<br/>";//displaying email 
    } 

$data['dbemail'] = $dbemail;//for passing to view 
$this->load->view('home', $data); //passing your value to view 
} 

Answer 3

首先，您需要从模型中的数据库中获取名称。更改查询行：

$query = $this->db->query("SELECT name, email FROM change_password"); 

然后使用该名称中的数据控制器，你可以试试这个：

function checking() 
{ 
    $email=$this->input->post('email'); 
    $this->load->model('login_model'); 
    $data['dbemail']=$this->login_model->email(); 
    $name = $data['dbemail']['name']; // example usage to retrieve name in controller 
    $this->load->view('home', $data); 
} 

现在名称的数据可在控制器$name。

控制器：

public function checking() 
{ 
$email=$this->input->post('email'); 
$this->load->model('login_model'); 
$data['dbemails']=$this->login_model->email(); 
$this->load->view('home', $data); //passing your value to view 
} 

型号

public function email() 
{ 
$this->db->select("email"); // the row of the table you want to select. 
$this->db->get('change_password'); //table name. you can still use your query, its just much neat when you use a specific query builder. 
$result = $this->result(); //giving you a result of type object 
return $result; 
} 

查看

foreach ($dbemails as $dbemail) 
{ 
    echo $dbemail->email; // the '->' will be the identifier of which row you want to get or display, i assume its email beacause you specify it in the model. 
} 

希望这你想找的。
