problem with passing multiple arrays from controller to view in CI

我正在使用代码点火器，我正试图发送多个数组来查看

这是控制器中的多个数组我将这个数组传递给视图

$data=Array ( 
  [email] => Array ( 
    [abv] => Array ( 
      [name] => Abv 
      [version] => 1.0.7 
      [description] => Get the contacts from a Abv account
      [base_version] => 1.8.4 
      [type] => email 
      [check_url] => http://m.abv.bg 
      [requirement] => email 
      [allowed_domains] => Array ( 
         [0] => /(abv.bg)/i
         [1] => /(gyuvetch.bg)/i
         [2] => /(gbg.bg)/i
      )
      [imported_details] => Array ( 
        [0] => first_name
        [1] => email_1
      ) 
    ) 
  )
)
$this->load->view('view', $data)

这是视图，

<?php
  foreach($data as $type=>$providers) {
    if ($type == 'email')
      "<optgroup label='email group'>"
    else
      "<optgroup label='social group'>";
    foreach ($providers as $provider=>$details)
      "<option value='{$provider}'".($_POST['provider_box']==$provider?' selected':'').">{$details['name']}</option>";
    "</optgroup>";
  }
?>

它不打印任何东西。你能解释一下为什么它不起作用吗?

您错过了回显，这可能解释了为什么没有打印出来。例如:

echo "<optgroup label='email group'>";
