Question

似乎get_instance()在Codeigniter 4中不再起作用。但是我需要从BaseController到我的custom_helper中获得一些价值。这是我的代码段：

BaseController.php

<?php namespace App\Controllers;
class BaseController extends Controller
{
 protected $helpers = ['custom'];
 public function initController(...) {
  parent::initController(...);

   $myconfig = config('MyConfig');
   $this->languages = $myconfig->languages;
   $this->selected_lang = $myconfig->site_lang;
   $lang_segment = $this->request->uri->getSegment(1);
   foreach ($this->languages as $lang) {
    if ($lang_segment == $lang->short_form) {
      $this->selected_lang = $lang;
      $this->lang_base_url = base_url() . $lang->short_form . "/";
    }
   }
 }
}
// Here I need to pass ($this->selected_lang) value to my custom_helper.

custom_helper.php

<?php
 if (!function_exists('trans')) {
    function trans($string)
    {
        $language_translations = get_translation_array($this->selected_lang->id);
        // --> Here I want to get ($this->selected_lang->id) value from BaseController.
        
        if (!empty($language_translations[$string])) {
            return $language_translations[$string];
        }
        return "";
    }
 }
 function get_translation_array($land_id)
 {
    .......
 }

我不确定是否可以！我是CI4的新手。请提出是否有解决方案。预先感谢。

您应该在帮助程序中执行所有操作，而不是调用BaseController

FBO = glGenFramebuffers(1)
DBO = glGenRenderbuffers(1)

glBindRenderbuffer(GL_RENDERBUFFER, DBO)
glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT, 1280, 720)

glBindFramebuffer(GL_FRAMEBUFFER, FBO)
glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, DBO)
glBindFramebuffer(GL_DRAW_FRAMEBUFFER, 0)

尽管我不知道您要做什么，但我希望这能对您有所帮助
