using namespaces and file paths in php properly

having mutiple issues with file paths and using namespaces and not sure why it seems they wont load.

Fatal error: Uncaught Error: Class "MD\model\TodoModel" not found in /var/www/html/app/controller/TodoController.php:7 Stack trace: #0 /var/www/html/app/view/todos/index.php(4): include() #1 {main} thrown in /var/www/html/app/controller/TodoController.php on line 7

here is code

<?php

set_include_path('app/model/');
//require '../model/TodoModel.php';
use MD\model\TodoModel;

class TodoController extends TodoModel {
    public function viewTodos() {
        return $this->selectAllTodos();
    }

    public function add_Todo($todo, $data) {
        return $this->addTodo($todo, $data);
    }

    public function edit_Todo($id) {
        return $this->editTodo($id);
    }

here is model code

Why MD/ ? also never capitalize paths MD/ is your project folder? or is that some part of the namespace I'm just not keen to?

set_include_path('app/model/'); //require '../model/TodoModel.php';

You realize both these paths are not even the same right?

MD•9mo ago

actually I removed those

b1mind•9mo ago

https://www.w3schools.com/html/html_filepaths.asp

MD•9mo ago

took out all the md

b1mind•9mo ago

why did you even have it xD that makes me think you don't understand paths at all mate typically I don't think you would even be calling for /app/ but you would want to do /app being at the root/ of your project

MD•9mo ago

idk how php handles that because it seems different in go it was very easy in php it's not

b1mind•9mo ago

again... paths are paths man

MD•9mo ago

in php you have namespaces, require, include,

b1mind•9mo ago

so what

MD•9mo ago

ive tried them all and nothing has worked

Fatal error: Uncaught Error: Class "model\TodoModel" not found in /var/www/html/app/controller/TodoController.php:5 Stack trace: #0 /var/www/html/app/view/todos/index.php(4): include() #1 {main} thrown in /var/www/html/app/controller/TodoController.php on line 5

b1mind•9mo ago

What are you trying now since you changed the above

MD•9mo ago

that's closest I got so far

<?php
namespace controller;
use model\TodoModel;

class TodoController extends TodoModel {
    public function viewTodos() {
        return $this->selectAllTodos();
    }

    public function add_Todo($todo, $data) {
        return $this->addTodo($todo, $data);
    }

    public function edit_Todo($id) {
        return $this->editTodo($id);
    }

    public function update_Todo($id, $topic, $task) {
        return $this->updateTodo($id, $topic, $task);
    }

    public function delete_Todo($id) {
        return $this->deleteTodo($id);
    }
}

<?php
namespace controller;
use model\TodoModel;

class TodoController extends TodoModel {
    public function viewTodos() {
        return $this->selectAllTodos();
    }

    public function add_Todo($todo, $data) {
        return $this->addTodo($todo, $data);
    }

    public function edit_Todo($id) {
        return $this->editTodo($id);
    }

    public function update_Todo($id, $topic, $task) {
        return $this->updateTodo($id, $topic, $task);
    }

    public function delete_Todo($id) {
        return $this->deleteTodo($id);
    }
}

it says it cant find "model\TodoModel"

<?php
namespace model;

that's model folder with TodoModel both controller and model folders are in the app folder trying include ../model/TodoModel.php, require ../model/TodoModel.php and use model\TodoModel all yield the same error if trying set_include_path("app/model/") and others have failed even full paths didnt work

b1mind•9mo ago

omg mate... you really don't understand paths have you tried /app/model? 😉 like I said

MD•9mo ago

yes it failed

b1mind•9mo ago

/model/filename?

MD•9mo ago

yep

b1mind•9mo ago

looks like you need to learn how then 😄 you do know that ../ and are not the same right? and / is root?

MD•9mo ago

yes I use linux daily

b1mind•9mo ago

yea I know that is why I'm laughing cause I would think you know this shit

MD•9mo ago

well php is different

b1mind•9mo ago

paths are paths man idk how many times I gotta say this

MD•9mo ago

if remove use model\TodoModel; this then the extends fails if you try any combination of include, or require with the path to the folder it still can't find it you get errors like this

b1mind•9mo ago

So you have to import the correct path b4 use will work ya? LIke you have to give the namespace the correct path before you can use its shorthand

there's an example

b1mind•9mo ago

right cause where is it looking for model\TodoModel.... you calling it from inside /app/controller yes?

MD•9mo ago

you cant use backslashes in keyword use it only allows forward

b1mind•9mo ago

so its looking for /app/controller/model/TodoModel but you want /app/model/ Am I wrong in seeing this ?

MD•9mo ago

no that is what im trying to achieve but the way php does things im not reaching it correctly

b1mind•9mo ago

wait I read that wrong so its doing this

MD•9mo ago

use model/TodoModel yields an unexpected ; error so syntax fail

b1mind•9mo ago

/app/controller/app/model xD

MD•9mo ago

../ would take you one level out of controllers putting you in app which has model folder in it

b1mind•9mo ago

do you need to define __DIR__./model/ or something?

MD•9mo ago

yet php doesnt acknowledge it ive tried that too

b1mind•9mo ago

https://opensource.com/article/23/4/autoloading-namespaces-php

Opensource.com

Use autoloading and namespaces in PHP

PHP autoloading and namespaces provide handy conveniences with huge benefits.

MD•9mo ago

read that too

b1mind•9mo ago

Scroll down the PSR-4 bit

MD•9mo ago

you need composer

b1mind•9mo ago

Well mate idk what to tell you don't use namespaces then

MD•9mo ago

it's part of php now so it's needed

b1mind•9mo ago

All of these examples use / root paths though

MD•9mo ago

im used to the php 5 days this is way different it's like Java now usually I dont have trouble with paths this is just a weird one

b1mind•9mo ago

its not weird you just have to fingure out your mental block paths work the same anywhere You just need to know how it handles the paths 😄 Like these do show it going outside of app too right? idk hf with this 😂 glad its not me 🖖

MD•9mo ago

idk either this language has changed a lot and ive only used php 3 times in my life mainly it's Java or C

b1mind•9mo ago

yea mate.. your name spaces look like they need to start with \namespace from all the examples I see the whole / to \ drives me a bit nuts 🤣

MD•9mo ago

yeah php enforces \ on namespaces

b1mind•9mo ago

yea idk man I can't be of anyhelp as I don't know it well enough but seems pretty clear cut 🤷‍♂️ I would try an example from one these in your project Get it working first then make your own 😉

MD•9mo ago

maybe jochem or epic will provide insight because im not gonna make any progress til this works this could be all day epic showed me with composer that's what i know 😄 just never setup composer with php and apache in docker lord even composer failed yeah even in the same damn folder it cant find it that's beyond me
