Codeigniter 聯接 Oracle database 要改的地方

Codeigniter version 1.6.3
Oracle version 10.2.0.4 use oci8

遇到這個 error :
Message: ocifetchinto() expects parameter 1 to be resource, null given

// 這個檔 \system\database\DB_driver.php 改成..

// $RES->num_rows	= $RES->num_rows();

if ($this->dbdriver == 'oci8')
{
  $RES->stmt_id		= $this->stmt_id;
  $RES->curs_id		= NULL;
  $RES->limit_used	= $this->limit_used;
}
$RES->num_rows	= $RES->num_rows();


解決沒有使用 UTF8 的問題

// 這個檔 \system\database\drivers\oci8\oci8_driver.php
// 改兩個地方:
function db_connect() 的
return @ocilogon($this->username, $this->password, $this->hostname,$this->char_set);

db_pconnect() 的
return @ociplogon($this->username, $this->password, $this->hostname,$this->char_set);


codeigniter 的連線設定

$db['default']['hostname'] = '//172.20.10.6/DB1';
$db['default']['username'] = "scott";
$db['default']['password'] = "*****";
$db['default']['database'] = "DB1";
$db['default']['dbdriver'] = "oci8";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = TRUE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";

codeigniter 的 oracle driver 問題還不少, 同一隻程式第二個 sql select 的結果跟第一個一樣…

要改

/system/database/drivers/oci8/oci8_driver.php
的159行
if ( ! is_resource($this->stmt_id))
{
  $this->stmt_id = ociparse($this->conn_id, $this->_prep_query($sql));
}
改成
$this->stmt_id = ociparse($this->conn_id, $this->_prep_query($sql));
就夠了.

設定 .htaccess 讓 網址比較短

CodeIgniter – Open source PHP web application framework

設定 .htaccess 讓 網址比較短

codeigniter 網頁提到
http://codeigniter.com/user_guide/general/urls.html

可以把www.your-site.com/index.php/news/article/my_article
變成
www.your-site.com/news/article/my_article

步驟:
改 apache 的 virtual host file
Options FollowSymLinks
在 /xxx/username/ci/ 下建 .htaccess
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond $1 !^(index.php|images|robots.txt)
RewriteRule ^(.*)$ /rimmon/ci/index.php/$1 [L]
</IfModule>
