Database error in core/Loader.php -- postgresql + codeigniter - php

i am getting the following error :
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php
Line Number: 346
my database.php is :
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'usertest';
$db['default']['password'] = '';
$db['default']['database'] = 'usertest';
$db['default']['port'] = '5433';
$db['default']['dbdriver'] = 'postgre';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
What is the possible solution. I do not want to $db['default']['db_debug'] = FALSE;
as even after doing this i am still not able to connect to db.
EDIT :
Changed the port to 5432. still it doesnt work

Set Set $db['default']['pconnect'] = FALSE; and check once again.

Some database drivers (such as PDO, PostgreSQL, Oracle, ODBC) might
require a full DSN string to be provided. If that is the case, you
should use the ‘dsn’ configuration setting, as if you’re using the
driver’s underlying native PHP extension, like this:
$db['default']['dsn'] = 'pgsql:host=localhost;port=5432;dbname=database_name';
from official documentation of codeigniter

Try:
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = FALSE;

Check your db driver name. I am pretty sure it is "postgres" and not "postgre."

unable to connect database : Codeigniter

I have noticed some unexpected behavior while connecting MySQL Codeigniter
Here is scenario:
-> I configured database library for autoload. (config/autoload.php)
$autoload['libraries'] = array('database', 'session');
-> But after configuring that, I can't open anything. I mean to say, Controller or View.
Have I done something wrong?
$active_group = 'default';
$active_record = TRUE;
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'root';
$db['default']['password'] = 'password';
$db['default']['database'] = 'myfamilyfirst';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = FALSE;
$db['default']['stricton'] = FALSE;
I tried to set $db['default']['autoinit'] = TRUE; to $db['default']['autoinit'] = FALSE;
Now I can open the pages but unable to connect the database.
Please help.
Probably you are using new xampp or wamp. So it will not support mysql.
Change this
$db['default']['dbdriver'] = 'mysqli'; # Change
In codeignator latest version we need to connect database using Mysqli. So in database file you need to give database driver as mysqli like this,
$db['default']['dbdriver'] = 'mysqli';
New codeignator version have mysqli dbdriver. If we have add mysql instated mysqli then shows following error.
Message: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead
Correct way is : $db['default']['dbdriver'] = 'mysqli';
Please make sure that your database username and password matches. Sometimes, these little things matters a lot.

code igniter error: Unable to connect to your database server using the provided settings. Filename: core/Loader.php Line Number: 346

I'm developing a website application using codeigniter at localhost and then i host it in hawkhost.
At localhost it runs well, but at host there's and error :
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php Line Number: 346
this is my db configuration
$active_group = 'default';
$active_record = TRUE;
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = '****';
$db['default']['password'] = '****';
$db['default']['database'] = '****';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
I know many people already asked this problem but it doesn't seems to solve anything on my case.
changing $db['default']['db_debug'] = TRUE; to false only hide the error but when i tried to get data from query it doesn't return anything.
I also tried to change $db['default']['pconnect'] = FALSE; to true and still doesn't work.
Any help please?
Just change localhost to the local ipaddress i.e. 127.0.0.1 and it will start working.
$db['default']['hostname'] = 'localhost';
to
$db['default']['hostname'] = '127.0.0.1';
In my case setting pconnect to false worked.
$db['default']['pconnect'] = FALSE;
The problem is really due to credentials.
I test it using simple code to check if connection can be made.
The problem is in username, i realize there's additional suffix when using hosting. such as suffix_user
I think the same errors in Core/Loader.php Line Number: 346 has the same solution. make sure the username, password and host are right.
It's solved. Thank you everyone for helping.
Just change
$db['default']['hostname'] = 'localhost';
to
$db['default']['hostname'] = '127.0.0.1';
and voila.
Most of the time this problem happens when codeigniter is in live environment.
That’s why I assumed a domain name ‘(example: domainname.com)’ and after creating a mysql database (example: testDb) and user name (example: testUser) you will find a prefix name automatically added with your mysql database name and user name like ‘domainname_ testDb’ and ‘domainname_ testUser’.
Now in codeigniter /application/config/database.php edit following:
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'domainname_ testDb ';
$db['default']['password'] = '*******';
$db['default']['database'] = 'domainname_ testUser';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre']= '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'domainname_ testDb ';
$db['default']['password'] = '*******';
$db['default']['database'] = 'domainname_ testUser';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre']= '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
If anyone else is having this issue, try disabling SE-Linux if you have it enabled. It was causing the connection issues for me, with php 5.4.
Also worth checking is switching
$db['default']['dbdriver'] = 'mysql';
to
$db['default']['dbdriver'] = 'mysqli';
as mysql is depreciated after php 5.5.

Connection to remote mysql from localhost

I have searched the net to no solution for a problem I am facing.
I am working on a codeigniter project which I am running on a localhost Apache Server. For the database, I am attempting to connect from CI's database.php configuration file to connect to a remote server.
The following is my configuration
$active_group = 'default';
$active_record = TRUE;
$db['default']['hostname'] = 'remotedatabase.com';
$db['default']['username'] = 'remote_2102Dev';
$db['default']['password'] = '1q2w3e4r5t';
$db['default']['database'] = 'remote_cs2102';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
I have tried to connect to the remote Database via mysql workbench 5.5. So that means I have did the configuration correctly at the server side.
Please help me. Is this CI problem or there is something wrong with my settings. Thank you.
Check host entry # remotedatabase.com. It should be % in host
If your PHP version is >= 5.3 set db_debug to false:
$db['default']['db_debug'] = FALSE;

Connect to IBM DB2 from Codeigniter

I have never worked with DB2 before. I am trying to connect from codeigniter. I have used the following settings in my database config file:
$db['default']['hostname'] = 'ipAddress';
$db['default']['port'] = 'portNumber';
$db['default']['username'] = 'uname';
$db['default']['password'] = 'pword';
$db['default']['database'] = 'myDBName';
//$db['default']['dbdriver'] = 'pdo';
$db['default']['dbdriver'] = 'odbc';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
and it throws the following error:
Unable to connect to your database server using the provided settings.
Filename: C:\xampp\htdocs\archive\system\database\DB_driver.php
Again, I am totally new to DB2, so in case I need to install anything extra (I assume the driver is already included in my latest CI download) or I need to define a dsn (please let me know how to do that if i require that) please do let me know, will very much appreciate your help.
Yes, you need to install the IBM Data Server Client package, or at least Runtime Client. Download the appropriate driver from http://www-01.ibm.com/support/docview.wss?uid=swg27016878
The manual explains how to configure DB2 access from a PHP application.
You need to add the full connection to the hostname parameter , as the following code
$active_group = 'default';
$active_record = FALSE;
$db['default']['hostname'] = "driver={IBM db2 odbc DRIVER};Database=DBNAME;hostname=localhost;port=50000;protocol=TCPIP;" . "uid=username; pwd=password";
$db['default']['username'] = 'username';
$db['default']['password'] = 'password';
$db['default']['database'] = 'DBNAME.SCHEMANAME';
$db['default']['dbdriver'] = 'odbc';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
