php - Codeigniter - 无法调用系统的 lang() 函数

Question

尝试调用作为 codeigniter 的系统/助手 (language_helper.php) 一部分的 lang() 函数，导致 fatal error

Fatal error: Call to undefined function lang()

$def_actions['add'] = array('name' => lang('carbogrid_add'), 'alias' => 'add', 'url' => $this->add, 'icon' => 'ui-icon-circle-plus', 'toolbar' => TRUE, 'grid' => FALSE);

Answer 1

你必须在这样做之前加载助手:

$this->load->helper('language');

$def_actions['add'] = array('name' => lang('carbogrid_add'), 'alias' => 'add', 'url' => $this->add, 'icon' => 'ui-icon-circle-plus', 'toolbar' => TRUE, 'grid' => FALSE);
