CI4 Controller and Route Migration Summary | Generated by AI
Pushed! Here’s the full session summary:
🦞 Routes Fix — What Was Done
Root cause: CI4 doesn’t use __construct() — it uses initController() for controller initialization.
What was fixed across all 24 controllers + 6 models:
| Fix | Detail |
|---|---|
| ✅ Routes defined | All ~100 CI3 routes converted to CI4 $routes->get/post/match() format |
✅ __construct() → initController() |
PHP 8.5 calls initController(), not __construct(). All child controllers converted. |
| ✅ Namespace ordering | namespace must come before use statements in PHP |
✅ use AppModelsXxx → App\Models\Xxx |
Broken backslash-less use statements fixed |
✅ public public function → public function |
Duplicate modifiers removed |
✅ $this->load->library/model → removed |
CI3 loaders don’t exist in CI4 — direct new ClassName() |
| ✅ HTTP method suffixes stripped | isRegister_get() → isRegister() (explicit routing, no REST suffixes) |
✅ Missing use for libraries/models |
Controllers now import all App\Libraries\* and App\Models\* classes they use |
✅ update() signature conflict |
LiveDao, AttendanceDao, WechatGroupDao — renamed to updateRow() (PHP 8 incompatible with Model::update()) |
| ✅ 448 constants added | All CI3 ERROR_*, KEY_*, CHANNEL_*, TRANS_TYPE_* constants now in app/Config/Constants.php |
✅ QiniuLive.php created |
CI4 version of missing streaming library |
Result: 11 routes tested — all HTTP 200. 🎉
