Codeigniter 2.2.2 / How to print the array data in a "View" which is passed in from a controller?

我没有收到从我的控制器传递到我的视图的任何 "country" 数据。这是我的控制器:

    public function country_destination()
{

    $this->load->model('model_admin');
    //Calling the get_unique_states() function to get the arr of state. Model already loaded.
    $arrCountries = $this->model_admin->get_unique_countries();

    //Getting the final array in the form which I will be using for the form helper to create a dropdown.
    foreach ($arrCountries as $countries) {
        $arrFinal[$countries->country] = $countries->country;
    }
    $data['countries'] = $arrFinal;

            // Basis page data
            $data = array(
                'templateVersion'   => 'template1',
                'headerVersion'     => 'header1',
                'css'               => '<link rel="stylesheet" href="/css/compiled/index.css" type="text/css" media="screen" />
                                       <link rel="stylesheet" type="text/css" href="/css/lib/animate.css" media="screen, projection" />',
                'navBarVersion'     => 'navbar1',
                'main_content'      => 'detail-wrap/admin/country_destination', 
                'page_title'        => 'example.com - App',
                'footerVersion'     => 'footer1'
                );
            //echo "here";
            $this->load->view('detail-wrap/includes/template1', $data);      
}

在我看来,我想转储 $data 的内容,其中包括 $data[countries]。这将帮助我确定是否确实 'some' 数据正在传递并有助于进一步调试。

我试过了print_r($data);但我收到 'undefined variable: data' 错误。

注意: $data 数组的键被转换为变量

你必须做

print_r($countries);  //to print the countries

在您看来

你必须给这个数组一些key

 $data['somekey'] = array(
                'templateVersion'   => 'template1',
                'headerVersion'     => 'header1',
                'css'               => '<link rel="stylesheet" href="/css/compiled/index.css" type="text/css" media="screen" />
                                       <link rel="stylesheet" type="text/css" href="/css/lib/animate.css" media="screen, projection" />',
                'navBarVersion'     => 'navbar1',
                'main_content'      => 'detail-wrap/admin/country_destination', 
                'page_title'        => 'example.com - App',
                'footerVersion'     => 'footer1'
                );

并在键的帮助下在视图中访问此数据。 CI 将密钥作为普通 php 变量发送到 view

因此从视图中您可以访问 print_r($somekey)

在你的视图文件中,你可以这样写来以结构化格式显示数组数据。

echo "<pre>";

print_r($countries);
