使用Codeigniter从数据库中检索单词

Question

I have recently started using codeigniter and I am a bit stuck as it is all rather new to me.

I use to have a config file with database conection and this on it:

$qset = "select * from re_settings";
$rset = mysql_query($qset) or die(mysql_error());
$aset = mysql_fetch_array($rset);

and this would allow me to pull words from database by simply putting this on the site

<?=$aset['SiteTitle']?>

How can I do this in codeigniter? Do I need to have a controller to do this or is it something much simpler than that.

Answer 1

You'll need to become familiar with the concepts of MCV which is how Codeigniter is built on and your ORM framework.

There's a bunch of helpful resources on http://tutorialcodeigniter.com/ or the official docs http://ellislab.com/codeigniter/user-guide/database/examples.html

as an example

$query = $this->db->query('SELECT name, title, email FROM my_table');

foreach ($query->result_array() as $row)
{
    echo $row['title'];
    echo $row['name'];
    echo $row['email'];
}

Answer 2

I strongly recommend to use Datamapper along with CodeIgniter. You will be surprised on how it is easy to work with your MySQL database.

Say goodbye to "mysql_fetch_array" 's and such.
