Hi all this is my first question, and it might be that Im currently over confusing matters.... I have got a database config file which specifies the SQL database that is used. What I want to do is make it so that the database name is the same as the subdomain. Thus meaning that the same php can be used to access different databases. If you get me. Any help greatly appreciated.
$db['default'] = array(
'dsn' => '',
'hostname' => 'databaseserver',
'username' => 'admin',
'password' => 'password',
'database' => 'subdomain',
'dbdriver' => 'mysqli',
'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
);

I am hosting a CodeIgniter API on GCP App Engine and I cant connect to the GCP Cloud SQL. I create the instance and database, but when I try to conect via CI I got a timeout message
error screen
My databse config on CI is:
$db['default'] = array(
'dsn' => 'mysql:unix_socket=/instance_name/instancia;dbname=project_name',
'hostname' => 'http://00.000.00.00',//here i put the public ip from the sql instance
'username' => 'user',
'password' => 'passwd',
'database' => 'projeto',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => yes,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
I've been banging my head on this for a while, myself, and finally cracked it! Here's what my db config looks like:
$db['default'] = array(
'dsn' => '',
'hostname' => '/cloudsql/PROJECT-NAME:REGION:DATABASE',
'username' => 'USERNAME',
'password' => 'PASSWORD',
'database' => 'DATABASE_NAME',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
// 'db_debug' => TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
The important bits are that the dsn is empty and the hostname is the full path to the unix socket. The rest of it should be about the same.
Hope that helps you, too!
I Developed Codeigniter app with SQL server connection. it is properly connected when using PHP 5.6 on windows 7 PC, but same application not working on windows 10 with same PHP version. showing the error
$db['default'] = array(
'dsn' => '',
'hostname' => '192.168.0.241',
'username' => 'sa',
'password' => 'mypw',
'database' => 'dbsrver',

You might have some error in configuration. Make sure you have correctly configure database.
In application/config/databse.php
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => 'write password if any otherwise leave it empty',
'database' => 'Your_Database_Name',
'dbdriver' => 'mysqli',
'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
);
I have an autoloaded DB which has all its var set in the config/database.php file as a default group:
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => 'root',
'database' => 'dbname',
'dbdriver' => 'mysqli',
'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
);
In this default DB there is a table where I need to read an external DB, and I have all fields to get a new connection.
I need to connect both DB at the same time, but I cannot define the DB variables in the config/database.php as these are dynamic and may change depending on the DB (default) content.
My idea was this either to SET $db['external'] = [...] IN THE CONTROLLER and set the data from the default DB I read, or simply use a DNS:
Solution #1:
public function wordpress()
{
$DB = $this->load->database('default', true);
$wp_db = $DB->get_where('dbtable', ['type_needed' => 'wordpress'])->row();
$db['wp_db'] = array(
'dsn' => '',
'hostname' => $wp_db->mysql_host,
'username' => $wp_db->mysql_user,
'password' => $wp_db->mysql_password,
'database' => $wp_db->mysql_db,
'dbdriver' => 'mysqli',
'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,
);
$this->WPDB = $this->load->database('wp_db', true);
}
Solution #1 gives "You have specified an invalid database connection group (wp_db) in your config/database.php file." error
Solution #2:
$DB = $this->load->database('default', true);
$wp_db = $DB->get_where('dbtable', ['type_needed' => 'wordpress'])->row();
$wp_dns = "mysql://$wp_db->mysql_user:$wp_db->mysql_password#$wp_db->mysql_host/$wp_db->mysql_db";
$this->WPDB = $this->load->database($wp_dns, true);
Solution #2 gives a "Invalid DB Connection String" error
Ps: I'm moving to Laravel, but this project was built with CI already :)
the only thing you've to change in your function is the following
public function wordpress()
{
$DB = $this->load->database('default', true);
$wp_db = $DB->get_where('dbtable', ['type_needed' => 'wordpress'])->row();
$arrDbData = array(
'dsn' => '',
'hostname' => $wp_db->mysql_host,
'username' => $wp_db->mysql_user,
'password' => $wp_db->mysql_password,
'database' => $wp_db->mysql_db,
'dbdriver' => 'mysqli',
'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,
);
$this->WPDB = $this->load->database($arrDbData, true);
}
I found out Solution #2 is working but due to the dns connection which is a STRING you are to make sure the password is made of letters and numbers and NO SYMBOLS otherwise it screws up the string and does not read properly.
In my case the password was this one iidf#q0RDTh#)CrPo5PDLeVe so dashes and parenthesis created a problem where CI could not read the whole password.
I always get the following error in my codeigniter 3 application when I start using a sqlite3 database.
SQLite3::query(): Unable to prepare statement: 1, no such table: pages
I have read somewhere that this is the case when you have the wrong path to the databse. My database is located in application/db/pages.sqlite
This is the config for the sqlite database:
$db['pages'] = array(
'dsn' => '',
'hostname' => '',
'username' => '',
'password' => '',
'database' => APPPATH.'db/pages.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
);
What have I done wrong?
Try this, it worked for me before
'database' => 'sqlite:'.APPPATH.'db/pages.sqlite',
Also make sure that folder db is readable by your app.
First you need to check that sqlite3 php module is installed on your web server or not?
This will required to work Codeigniter3 sqlite3 db driver.
If its not working then provide 'dsn' string. This will definitely working.
First thing try to check your php.ini and uncomment this
extension=php_pdo_sqlite.dll
extension=php_sqlite3.dll
and try this
$db['default'] = array(
'dsn' => 'sqlite:application/db/pages.sqlite',
'hostname' => 'localhost',
'username' => '',
'password' => '',
'database' => '',
'dbdriver' => 'pdo',
'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
);
