如何从cakephp中的控制器获取数据

Question

$this->loadModel('Siteconfig');

$data=$this->Siteconfig->find('all');

foreach($data as $data)
{           
    $email=$data['Siteconfig']['email'];

    $companyname=$data['Siteconfig']['companyname'];

    $cfa=$data['Siteconfig']['cfa'];
}

以上是控制器

如何使用 CAKPHP 在视图中获取 cfa 数据？

Answer 1

将您的脚本修改为

$this->loadModel('Siteconfig');

$data=$this->Siteconfig->find('all');
$cfa = '';

foreach($data as $datum)
{           
    $email=$datum['Siteconfig']['email'];

    $companyname=$datum['Siteconfig']['companyname'];

    $cfa=$datum['Siteconfig']['cfa'];
}
$this->set('view_cfa',$cfa);

这将解决它。您的 foreach 正在重新分配 $data.

Answer 2

在你的控制器方法中，你可以使用这个

$this->set('var_name_in_view', $cfa);  //You will find the variable $cfa as $var_name_in_view in your view(You have to use $var_name_in_view in view)

您还可以一次将多个变量发送到您的视图

$this->set(compact('cfa', 'another_variable'));  //You can acceess using $cfa and $another_variable

Compact makes an array keeping the variable name as key and variable value as the value for the array key.
