How to configure connection setting for sqlite database in Openshift?
Below code is my connection setup in database.php:
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Sqlite',
'persistent' => false,
'database' => get_env('OPENSHIFT_DATA_DIR').'/database.sqlite',
'prefix' => ''
);
}
I have placed my sqlite db in path: "/var/lib/openshift/~/app-root/data"
When i access the website i receive the following error:
Parse error: syntax error, unexpected '(', expecting ')' in /var/lib/openshift/~/app-root/runtime/repo/app/Config/database.php on line 65
line 65: 'database' => get_env('OPENSHIFT_DATA_DIR').'/database.sqlite',
In PHP you can not use a function when declaring a class property.
If you must use that function you can write:
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Sqlite',
'persistent' => false,
'prefix' => ''
);
function __construct() {
$this->default['database'] = get_env('OPENSHIFT_DATA_DIR').'/database.sqlite';
}
}

We want to connect one of too many databases as a default.
as per user requriment so we want take a database name in a variable or Global variable.
we are unable to use any variable in Database.php file
so guys help me for this problem.
view code here Codeigniter 4.0.0
It has been a while since I tried to do "weird" things like attempting to assign dynamic variables in configuration files so I'm not entirely sure if CodeIgniter supports it. However, even if it does, I would suggest using the function designed for these sort of things:
https://codeigniter4.github.io/userguide/database/connecting.html#connecting-with-custom-settings
$custom = [
'DSN' => '',
'hostname' => 'localhost',
'username' => '',
'password' => '',
'database' => '',
'DBDriver' => 'MySQLi',
'DBPrefix' => '',
'pConnect' => false,
'DBDebug' => (ENVIRONMENT !== 'production'),
'cacheOn' => false,
'cacheDir' => '',
'charset' => 'utf8',
'DBCollat' => 'utf8_general_ci',
'swapPre' => '',
'encrypt' => false,
'compress' => false,
'strictOn' => false,
'failover' => [],
'port' => 3306,
];
$db = \Config\Database::connect($custom);
I suppose, since all else is the same except for database name you could also access the database configuration property for your default database and use $custom = array_replace($configDb, ['database' => $_SESSION['db_name']) to change out the database name. Obviously check that db_name exists and isn't empty and all that jazz. You could even put this entire logic in to a class with db_name as a constructor so you don't have to keep doing this all the time.
E.g. (untested):
namespace App\Config;
use InvalidArgumentException;
class DatabaseChooser extends \Config\Database
{
protected $dbName;
public function __construct(string $dbName = '')
{
$this->dbName = $dbName;
$config = $this->buildArr();
return parent::connect($config);
}
private function buildArr()
{
if (empty($this->dbName)) {
throw InvalidArgumentException('dbName cannot be empty');
}
$default = $this->defaultGroup;
if (property_exists($this, $default) && is_array($this->$default)) {
return array_replace($this->$default, ['database' => $this->dbName]);
} else {
throw new Exception('Invalid configuration.');
}
}
}
I'm sure you've considered it, but CI4 isn't exactly production ready afaik. To be honest, I'd be using something like Laravel, Lumen, or Symfony which already have an extensive and tested codebase, as well as many compatible third party packages.
I'm starting a new project where I want to use Codeigniter with SQLite. I searched information about this and I managed to conect and get data from my SQLite database but I have no idea of how can I create a CRUD for a table with this, I'm trying to do it the same way I did in the past with MySQL buy it is not working.
Here is what I did:
config/database.php
$db['default'] = array(
'dsn' => '',
'hostname' => '',
'username' => '',
'password' => '',
'database' => APPPATH.'/database/Pasapalabra.sqlite',
'dbdriver' => 'sqlite3',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
config/autoload.php
$autoload['libraries'] = array('database');
models/modelo_prueba.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class modelo_prueba extends CI_Model {
public function getTestData() {
return $this->db->get('preguntas')->result();
}
}
?>
controllers/Welcome.php
public function __construct() {
parent::__construct();
$this->load->library("grocery_CRUD");
}
public function prueba() {
$this->load->model('modelo_prueba');
$dataSet = $this->modelo_prueba->getTestData();
$this->load->view('data_view', [
'dataSet' => $dataSet
]);
}
views/data_view.php
<h4>Lets test the data</h4>
<?php
if($dataSet) {
foreach($dataSet as $dataItem) {
echo $dataItem->definicion . "<hr>";
}
}
?>
<h5>done!</h5>
This worked for me, it shows correctly all data in 'preguntas' database, but now I'm trying to create a CRUD just like I usually do with MySQL and it's working, it shows a database error.
The only thing that I have changed from the code of above is Welcome.php
public function prueba() {
$crud = new Grocery_CRUD();
$crud->set_table('preguntas');
$output = $crud->render();
$this->load->view("example.php", $output);
}
The error that is shown in the screen is the following:
A PHP Error was encountered

Anyone knows what is happening? There isn't any error with the database connection because the previous code worked, but it's like Grocery CRUD can't create a CRUD of an SQLite.
I'm working with Codeigniter 3.1.4 and I created the SQLite database with SQLite Manager (Firefox) 0.8.3.1
Thank you for your answers.
Hi I have found solution from grocery crud form post with works with sqlite3 you have to modify Grocery curd library first copy sqlite3 model from this link
http://www.grocerycrud.com/forums/topic/651-suport-for-sqlite3/
this model extending grocery_crud_model, just include grocery_crud_model in your sqlite model.
in grocery crud library find grocery_crud_model, where it is loading this model just replace with grocery_crud_sqlite3, and you are done. it will work perfect.
just remember you have to modify these lines manually on each update in future.
I'm sure this is more simple than I'm making it.
The error that I get...
Notice (8): Undefined property: Cake\Database\Connection::$config [... line 73]
The code on line 73...
Line 72: debug($conn);
Line 73: debug($conn->config);
Here's what $conn equals
$conn = object(Cake\Database\Connection) {
'config' => [
'password' => '*****',
'username' => '*****',
'host' => '*****',
'database' => '*****',
'driver' => 'Cake\Database\Driver\Postgres',
'persistent' => false,
'encoding' => 'utf8',
],
}
Anyone know why $conn->config isn't the right syntax?
There is no public property named $config only a protected $_config in the database connection class in Cake (http://api.cakephp.org/3.2/source-class-Cake.Database.Connection.html).
With the the database connection in Cake you must use the public function config() to get the configuration array.
$config = $conn->config();
I don't know what debug() does, but it's not returning a detailed representation of the properties of the object as would var_dump or as you could get from reflection. Don't rely on it to learn the interface of an object/class.
I am new to Cakephp, I am trying to install it. I extract everything and create the needed files/folders, now there is the following error:
Warning (2): include_once(C:\xampp\htdocs\TravelBuddy\app\Config\database.php): failed to open stream: No such file or directory [CORE\Cake\Model\ConnectionManager.php, line 67]
Warning (2): include_once() [function.include]: Failed opening 'C:\xampp\htdocs\TravelBuddy\app\Config\database.php' for inclusion (include_path='C:\xampp\htdocs\TravelBuddy\lib;.;C:\xampp\php\PEAR') [CORE\Cake\Model\ConnectionManager.php, line 67]
The file database.php does not exists. Do I have to create it?
Here is the code of ConnectionManager where the problem is:
protected static function _init() {
include_once APP . 'Config' . DS . 'database.php';
if (class_exists('DATABASE_CONFIG')) {
self::$config = new DATABASE_CONFIG();
}
self::$_init = true;
}
create inside: app/Config a file called database.php
now you need to configure your database connection like:
<?php
class DATABASE_CONFIG {
public $default = array (
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'yourusermysql',
'password' => 'passwordmysql',
'database' => 'nameofdatabase',
'prefix' => ''
);
public $test = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'user',
'password' => 'password',
'database' => 'test_database_name',
'prefix' => '',
//'encoding' => 'utf8',
);
}
?>
To avoid the given error you should do
if (class_exists('DATABASE_CONFIG', FALSE)) {
self::$config = new DATABASE_CONFIG();
}
i was struggling with same problem, but if the class didn't exist it should perform the remaining operation, and not giving me a fatal error.
http://www.php.net/manual/en/function.class-exists.php
Check and make sure the database.php file is committed in your git repo. Checkout the .gitignore file.
I can call SQL server 2008 from PHP with Microsoft Drivers for PHP for SQL Server But as Sqlsvr driver class is needed to use CakePHP with SQL server 2008, I got the driver file from following repository.
However, when running my test cakephp with following database.php
<?php
class DATABASE_CONFIG {
var $default = array(
'driver' => 'sqlsvr',
'host' => 'localhost\EPHP',
'login' => 'sa',
'password' => 'xxxxxxx',
'database' => 'Blog',
);
}
?>
I got following error:
Fatal Error (256): ConnectionManager::loadDataSource - Unable to import DataSource class .DboSqlsvr [CORE\cake\libs\model\connection_manager.php, line 185]
Then I have read all the you-cannot-make-cakePHP-work-with-sql-2008 discussions. Is there any resolution by now?
UPDATE: Let me rephrase my question. I would appreciate if someone successfully made CakePHP work with SQL 2008 and tell me the procedure he followed to do that.
After some research, I found this article ( http://book.cakephp.org/view/1652/Plugin-DataSources-and-Datasource-Drivers). Basically, you can not place your driver file in the directory ( \cakephp\cake\libs\model\datasources\dbo) where the "factory" driver files are located. Instead you should place the driver file in following directory of your baked cake.
your-cake-application\plugins\your-plugin-name\models\datasources\dbo
And then you should change your database.php in config accordingly.
<?php
class DATABASE_CONFIG {
var $default = array(
'driver' => 'your-plugin-name.DboSqlsrv',
'host' => 'localhost\EPHP',
'login' => 'sa',
'password' => 'xxxxxxx',
'database' => 'Blog',
);
}
?>
After this, I could run my cakephp app.
Assuming you have the datasources in the folder app/model/datasource/dbo_sqlsrv.php load it like this:
<?php
class DATABASE_CONFIG {
var $default = array(
'datasource' => 'sqlsvr',
'host' => 'localhost\EPHP',
'login' => 'sa',
'password' => 'xxxxxxx',
'database' => 'Blog',
);
}
?>
The difference is in the 'driver' vs 'datasource' keyword
