php - 当我在输入字段中使用数组类型名称时显示黑洞错误

Question

admin_add_newsletter.ctp

foreach($menu_page_1 as $menu_pages) {
    echo $this->Form->checkbox('top_links.',array(
        'type'=>'checkbox','id'=>'checked_box',
        'value'=>$menu_pages['MenuPage']['id'],
        'label'=>false,'div'=>false,'hiddenField'=>false,
        'saparator'=>'</td><td>'
    ));
    echo '<label for="top_links'.$menu_pages['MenuPage']['id'].'">'.
        $menu_pages['MenuPage']['name'].'</label>';
}

通讯控制器.php

if($this->request->is('post')) {
    print_r($this->data['Newsletter']['top_links']['']);
    exit();
}

错误

The request has been black-holed

Error: The requested address '/admin/newsletters/add_newsletter' was not found on this server.

帮助我了解如何在 cakephp 中使用复选框，其中包含从视图文件到控制器的所有检查值，而不会显示黑洞错误。

问题是您正在手动构建复选框选项，并在字段名称中添加一个点。

做到这一点的方法是这样做的蛋糕方式：

$options = array();

foreach($menu_page_1 as $menu_pages) {
    $options[$menu_pages['MenuPage']['id']] = $menu_pages['MenuPage']['name'];
}
echo $this->Form->select('top_links', $options, array(
    'multiple' => 'checkbox'
));
