The simple way to custom your site logo in Drupal8 is to upload your logo with the name logo.svg in your custom theme directory. The Path is something like : sites/YOUR-SITE.com/themes/MY-THEME/logo.svg. This will override the Drupal8 default logo.
The second way is from the Backend . Just go to Appearance->Settings->Global settings and in the “Logo image settings” give the path where your logo.png is.
Just change “YOUR-SITE.com” and “MY-THEME” with your custom folder names.
In the most example of drupal8 you will experiment the Hello World module. This is just a demostration how you can create your custom module within the new drupal8 concept.
But your application can be more complicated as just a Hello World module, you want may be create one module, multiple route and a custom twig template for each route
User case is if you want to create your own module but managing a multiple Route within one module.
When you add a new yaml file you should uninstall the modul and insatll it again. I haven’t found other solution for this right now ! This will help you if you can’t see any changes when you add some configuration or yml files.Or when you get following error:
Theme hook YOUR-TEMPLATE not found.
Let say you want to create a module to manage contact and edit them. My Module in this case is named “mymodule”
Let start to create the diffrent route in “mymodule.routing.yml” file:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
mymodule.contacts_show: path: '/contacts/show' defaults: _controller: '\Drupal\database\Controller\ContactController::getContacts' _title: 'Contacts' requirements: _permission: 'access content' mymodule.contact_edit: path: '/contact/edit/{id}' defaults: _controller: '\Drupal\database\Controller\ContactController::editContact' _title: 'Edit Contact' requirements: _permission: 'access content' |
Add your Conroller in src folder with the name ContactController.php:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
<?php namespace Drupal\mymodule\Controller; use Drupal\Core\Controller\ControllerBase; class ContactController extends ControllerBase { public function getContacts($name) { //here you can define you business logic, like Database querys , forms ...and you can transmit variable in the return array return [ '#theme' => 'contacts_show_page']; } public function editContact($id) { return [ '#theme' => 'contact_edit_page', '#id' => $id ]; } } ?> |
Create following yml file “mymodule.module”:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
<?php /** * Implements hook_theme(). */ function database_theme() { $templates = array('contacts_show_page' => array('template' =>'contacts_show'), 'contact_edit_page' => array('variables' => ['id' => NULL],'template' => 'contact_edit') ); return $templates; } |
At the end just create the Twig templates within your templates folder:
templates/contact_edit.html.twig
|
1 |
This is id : {{id}} |
templates/contacts_show.html.twig
|
1 |
This is the Contacts show twig template |
So now, you are able to create diffrent routes and templates using Drupal8 and transfer variables from the controller to the twig template
using your own business logic operations.
First install composer for all projects(Required User root)
|
1 2 |
curl -sS https://getcomposer.org/installer | php mv composer.phar /usr/bin/composer |
Then change directory to to the Drupal8 installtion and edit composer.json and add the drush line:
|
1 2 3 4 5 |
"require": { "composer/installers": "^1.0.21", "wikimedia/composer-merge-plugin": "^1.3.0", "drush/drush": "dev-master" }, |
at the end update compser with: (Required User www-data)
|
1 |
composer update |
if permissions Problem:
|
1 2 3 |
sudo chmod www-data.www-data composer.lock sudo chgrp www-data -R * (for the whole drupal8 installation) sudo chmod g+w vendor/* |
clear cache with: (Required User www-data)
|
1 2 3 |
drush cache-clear or drush cr |
or if you have your own site:
|
1 2 3 |
drush cache-clear --uri=YOUR-SITE-FLODER-NAME or drush cr --uri=YOUR-SITE-FLODER-NAME |
