Drupal8:Rendering multiple TWIG template

I meet this situation as i wanted to add some hard coded text bevor the pagination table. It is just a demonstration how to render multiple TWIG templates within one return and can be useful to add third party code like external services (RSS, Webservices …)

The “custom_html_content_page” template theme should be defined in mymodule.module file, something like:

And finally the TWIG template in the templates folder:

Drupal8:Basic Jquery Ajax custom module controller

In the previous tutorial (drupal8-create-module-with-multiple-route-and-custom-route-contoller-twig-template/) we have create a custom modul using different Route and some TWIG templates. Now  we want to call one of the route using Ajax .

First of all, we should have create a custom theme and add our custom JavaScript file in MY-THME.info.yml :

Now we have to define the “global-scripting” in the MY-THME.libraries.yml

In js/ajax.js we add the usual Jquery ajax code

Let explain what we have define in the js/ajax.js:
1. The HTML Link to click:

2. Then we have to prevent to reload the page with: event.preventDefault();
3. We get the content of the href attribute, because this will be the Ajax Route call:

4. Now we start the Ajax call , we will add a post variable, that indicate our controller that we are comming from an ajax request.
5. We set the URL in the browser with the Route using:

Why we do this ? Simple , if Google will index our link or user disable Javascript in the browser , we have then to be sure that the link will works without the ajax call . In the Controller we will have a condition using the post variable “ajaxCall”.
6. The Controller response will then displayed in the content div.


So now we have to extend the editContact($id) Method within the custom module Controller “ContactController”:

You will be able now to call your own Business Logic, extend and transfer your variables to the TWIG tempalte.
IMPORTANT: Don’t forget to define your variables first in mymodule.module . Clearing the cache if no changes can be very helpful.

drupal8: create module with multiple route and custom Route Contoller Twig Template

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:


Add your Conroller in src folder with the name ContactController.php:

Create following yml file “mymodule.module”:

At the end just create the Twig templates within your templates folder:



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.

Drush8 Drupal8 on unix system

at the end update compser with: (Required User www-data)

if permissions Problem:


clear cache with: (Required User www-data)

or if you have your own site:

Upgrade PHP 5.5 to 5.6 and PHP Warning PHP Startup Unable to initialize module

How to upgrade PHP to 5.6 is not a big challenge. In some cases , some manuell installed modul over pecl like imagick will not properly works. This is because some modul are compiled with the old  php module.

The error looks like:

So the new php 5.6 in this case is compiled with module API=20131226 . All what you have to do is to upgrade the php5-dev package and reinstall the modul again. In this case imagick.

That’s all.

Basically, if you want to install imagick for the first time you can use the following commands:

Add File imagick.ini in :
/etc/php5/cli/conf.d and
With content:

mysql_secure_installation – mysql-5.5 wheezy-security; urgency=high

Ifyou get following message during server upgrade:

Then you have to run following command to secure and restrict your Database aceess.

The test Database will be deleted and also the anoymous user access from the localhost.

multipart_chunk_size_mb – upgrade s3cmd from 1.0.0 to 1.5.2 AWS Ubuntu 12.04.3 LTS

if you get some of the following errors , you should upgrade the s3cmd from 1.0.0 to 1.5.2:

[Errno 104] Connection reset by peer
[Errno 32] Broken pipe

The Problem is that files with size more han 5GB will not be able to be uploaded to AWS S3.  It is recommended that s3cmd  should be updated to 1.5.2 . This update gives the possibilitities to split / chunk the uploaded file.

Update to the recent s3cmd Version

1. Backup your /root/.s3cfg file
2. Get the latest Version with:
wget http://sourceforge.net/projects/s3tools/files/s3cmd/1.5.2/s3cmd-1.5.2.tar.gz
3. tar zxf s3cmd-1.5.2.tar.gz
4. cd s3cmd-1.5.2/
5. apt-get install python-setuptools
6. python setup.py install
7. s3cmd –version
If this doesn’t work , then :  cp -a s3cmd /usr/bin/
8. s3cmd –version
9. s3cmd –configure

You can see now new options like : multipart_chunk_size_mb

SQLCipher for Android Tutorial, encrypt and backup SQLite database[Part3]

In Part1 , we have prepared the Database Handler Class, the User TableDefintion Class where other Tables can be also defined.
The User class ensures reading and writing data from the database.

In Part2  of this tutorial we have use the business logic to create and getting some user information from the database.

In this part, we will try to get and view the SQLite database file from the device and decrypt it using SQLiteManager for windows.

During the development you will be also not able to see the database file and open it with some SQLite Browser software, that is because your application resource folder will not be displayed in the internal device storage until you root your device or deploy the application. But there exist a way how to copy the database from the internal device to the external sdcard and from the sdcard we will be able to copy the database file to the Desktop and open it using SQLiteManager.

Hier is the copy code. We can placed anywhere in the Activity, but after creating the Database. More information  in Part 2.

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.nio.channels.FileChannel;
import android.os.Environment;
import android.util.Log;
import android.os.Environment;

 try {
    File sd = Environment.getExternalStorageDirectory();
    File data = Environment.getDataDirectory();

    if (sd.canWrite()) {
       	 Log.d("DatabaseHandler", "DatabaseHandler: can write in sd");
        //Replace with YOUR_PACKAGE_NAME and YOUR_DB_NAME
        String currentDBPath = "//data//{YOUR_PACKAGE_NAME}//databases//{YOUR_DB_NAME}.db";
       //Replace with YOUR_FOLDER_PATH and TARGET_DB_NAME in the SD card
        String copieDBPath = "/{YOUR_FOLDER_PATH}/{TARGET_DB_NAME}.db";
        File currentDB = new File(data, currentDBPath);
        File copieDB = new File(sd, copieDBPath);
        if (currentDB.exists()) {
       	  Log.d("DatabaseHandler", "DatabaseHandler: DB exist");
	  FileChannel src = new FileInputStream(currentDB).getChannel();
	  FileChannel dst = new FileOutputStream(copieDB).getChannel();
    	  dst.transferFrom(src, 0, src.size());
    } catch  (Exception e) {

After launching the application on the device, you will find the copied database in the defined copieDBPath.

Please note that  DB Browser for SQLite 3.5.0  software is not supporting SQLCipher decryption for Windows until i write this tutorial.

We will use SQLiteManager that support SQLCipher decryption.

Copie or move the database to your desktop and download the SQLiteManager for windows.

After executing the software open the database file, the SQLiteManager will ask you to give the database password. The Password is defined in the DatabaseHandler class

private static final String DB_PASSWD = "YOUR_SECRET_KEY_HERE";


You will be able now to see your decrypted database data.

if you get one of this errors:
dalvikvm E ERROR: couldn't find native method
dalvikvm E Requested: Lnet/sqlcipher/database/SQLiteDatabase;.native_getDbLookaside

Be sure that you are using the latest SQLCipher for Android
and you have the ZIP file icudt46l.zip in the assets folder.
