Q - How to fix yaml file error in phpBB3 custom extension ?

[Raja Pdl]

I've (1) created phpBB 3 extension named "m_example",
(2) extract in "ext" folder
(3) Go to ACP > Customize and click on "Enable"
(4) After that, if I go to any page of the board, it displays the following error

m_example_main:
path: /mextension

How can I fix it ?

version - phpBB 3

[eange08]

You should change mindphp.m_example.controller.main_controller to mindphp.m_example.controller:main_controller to match the syntax expected by phpBB.

So, your routing.yml file should look like this:

โค้ด: เลือกทั้งหมด

m_example_main:
  path: /mextension
  defaults: 
    _controller: mindphp.m_example.controller:main_controller

After making this change, remember to clear phpBB's cache and try enabling the extension again.

[eange08]

You can check the structure of each file in the phpBB extension at: https://area51.phpbb.com/docs/dev/maste ... ml#routing


It's recommended that the path name should match the controller name, for example:

โค้ด: เลือกทั้งหมด

m_example_main:
  path: /m_example_main
  defaults: 
    _controller: mindphp.m_example.controller:main_controller

This helps maintain consistency and makes it easier to understand the file structure.

I changed the codes as following and diabled and enabled again, clear the cache, but it displays the same error

โค้ด: เลือกทั้งหมด

m_example_main:
path: /m_example_main

  _controller: mindphp.m_example.controller:main_controller

I also tested like

โค้ด: เลือกทั้งหมด

m_example_main:
path: /m_example_main
defaults: { _controller:mindphp.m_example.controller:handle }

But it displays the same error
What can I do now ?

[eange08]

It seems your information is too limited. Here's a checklist to troubleshoot:

1. **What error message appears?**
2. **Check the controller file**: Does it contain a method named `main_controller`?
3. **Verify the services file**: Make sure it correctly references the controller path.

Sample setup for `services`:
```yaml

โค้ด: เลือกทั้งหมด

   
   services:
       mindphp.m_example.controller:
           class: mindphp\m_example\controller\main  # Ensure this matches the controller file name
           arguments:
               - '@config'
               - '@controller.helper'
               - '@language'
               - '@template'
   ```

Confirm each point to help locate any misconfiguration.

Here's the response in English:

The `services.yml` file and the PHP file you provided seem correct in terms of YAML structure and PHP class setup. However, the YAML error may be due to incorrect indentation or formatting issues in the `services.yml` file. To avoid the error, try the following adjustments:

1. **Correct `services.yml` Formatting:** Ensure proper YAML syntax with the following structure:

```yaml

โค้ด: เลือกทั้งหมด

  services:
       mindphp.m_example.controller:
           class: mindphp\m_example\controller\main
           arguments:
               - '@config'
               - '@controller.helper'
               - '@language'
               - '@template'

2. **Spacing and Indentation:**
- Make sure `services:` starts at the beginning of the line without any spaces in front.
- Use 4 spaces for indentation under `mindphp.m_example.controller` to correctly define the `class` and `arguments`.

3. **Clear the Cache:** After making these adjustments, clear the phpBB cache by going to `ACP > General > Purge the cache`. Alternatively, navigate to the `cache` folder in phpBB and delete all files except for `.htaccess` to force phpBB to reload the updated files.

4. **Check File Structure:** Verify that your folder and file structure are correct:
- `ext/mindphp/m_example/config/services.yml`
- `ext/mindphp/m_example/controller/main.php`

5. **Test Again:** After clearing the cache and verifying the structure, try enabling the extension once more to see if the issue is resolved.

Based on the properties you've decided to use in the controller, we can adjust the `services.yml` and the `controller` to align with this setup:

### `services.yml`

In `services.yml`, specify only the `arguments` that match the properties in the controller's constructor, removing any unnecessary arguments:

```yaml

โค้ด: เลือกทั้งหมด

services:
  mindphp.m_example.controller:
    class: mindphp\m_example\controller\main
    arguments:
      - '@config'
      - '@cache'
      - '@dbal.conn'
      - '@template'
      - '@user'
      - '@controller.helper'
      - '@service_container'
      - '@request'
      - '@auth'
      - '%core.table_prefix%'

### `controller/main.php`

Update the controller to use only the needed properties:

```php

โค้ด: เลือกทั้งหมด

<?php
namespace mindphp\m_example\controller;

class main
{
    protected $config;
    protected $cache;
    protected $db;
    protected $template;

    protected $helper;
    protected $phpbb_container;
    protected $request;
    protected $auth;
    protected $table_prefix;

    public function __construct(\phpbb\config\config $config, \phpbb\cache\service $cache, \phpbb\db\driver\driver_interface $db, \phpbb\template\template $template, \phpbb\user $user, \phpbb\controller\helper $helper, Container $phpbb_container, \phpbb\request\request $request, \phpbb\auth\auth $auth, $table_prefix) {
        $this->config = $config;
        $this->cache = $cache;
        $this->db = $db;
        $this->template = $template;
        $this->user = $user;
        $this->helper = $helper;
        $this->phpbb_container = $phpbb_container;
        $this->request = $request;
        $this->auth = $auth;
        $this->table_prefix = $table_prefix;
    }

    public function handle()
    {
        // Assign a greeting to the template for testing
        $this->template->assign_vars([
            'GREETING' => 'Hello from m_example!',
        ]);

        return $this->helper->render('m_example_template.html');
    }
}

### Summary

- **`services.yml`**: Only include the arguments specified in the constructor.
- **`controller/main.php`**: Keep only the properties that are actively used.
