Multiple Databases In Codeigniter

Here is the general transcript from the video, however the video includes a lot more:

Hello, this is Jedidiah Reeser from JedidiahMedia.com. Today, I’m going to show you how to connect to multiple databases in CodeIgniter.

Step 1
I am going to add the secondary database details in the config folder. I will open database.php in the config folder which is found in the application folder. I will copy and paste the database settings and change default to second_db.

Step 2
Next, I will go to the controller and add the code to load the model.

 $this->load->model('example','', TRUE);

Step 3
Then I will go to the model and make it connect to the second database. To do this, I will add a private variable in the class. In the constructor function I will load the second database. I will create a function to run a query using the second database.

class Example extends Model
{
  private $second_db;

  function Example()
  {
      parent::Model();
      $this->second_db = $this->load->database('second_db', TRUE);
  }

function get_latest()
{
    $info = '';
    $query = $this->second_db->query('SELECT * FROM wp_posts limit 3');

    if ($query->num_rows() > 0 ){
      $info .= '<ul>';
       foreach ($query->result() as $row)
        {
            $info .= '
            <li>
              <h3>'.$row->post_title.'</h3>
            <br />
            <div>'.$row->post_excerpt.'</div>
           </li>
            ';
        }
        $info .= '</ul>';
    }

    return $info;

    }
}

Step 4
After that I will open the controller and send the information to the view.

 $this->load->model('example','', TRUE);

 $data['posts'] = '
     <div id="blogposts">
    <h2>Recent Posts</h2>
    ';
    $data['posts'] .= $this->example->get_latest();

    $data['posts'] .= '</div>';

    $this->load->view('welcome_message', $data);

Step 5
Then, I will go to the view and display the information.

    <?=$posts;?>

Example: Changes this 1234567890  into this (123) 456-7890

function formatphone($phone){
if (empty($phone)) return "";

if (strlen($phone) == 7) {
    sscanf($phone, "%3s%4s", $prefix, $exchange);
} else if (strlen($phone) == 10) {
    sscanf($phone, "%3s%3s%4s", $area, $prefix, $exchange);
} else if (strlen($phone) > 10) {
    if(substr($phone,0,1)=='1') {
        sscanf($phone, "%1s%3s%3s%4s", $country, $area, $prefix, $exchange);
    } else {
        sscanf($phone, "%3s%3s%4s%s", $area, $prefix, $exchange, $extension);
    }
} else {
    return $phone;
}

$out = "";
$out .= isset($country) ? $country.' ' : '';
$out .= isset($area) ? '(' . $area . ') ' : '';
$out .= $prefix . '-' . $exchange;
$out .= isset($extension) ? ' x' . $extension : '';
return $out;
}

Today, I found an additional web-tool that also creates diagonal ribbon banners that I recommend you take a look at. This webpage works similarly to the first one: you enter in information, pick out some colors, and the webpage generates code for you to enter into your blog.

quickribbon.com

I wanted to share this tool with you because the banner it generates is very sharp-looking and you can also choose to add a URL link or hyperlink to be embedded in the banner. Check it out!

My other blog article on diagonal ribbon banners can be found here:

Use this tool to generate code for a diagonal ribbon in the corner of you website: http://www.websiteribbon.com/

All you have to do is go to the website, enter your message, choose font size and color, choose banner type, click “generate” and then place the generated code in your webpage.

Here is an example that I made using this cool little tool:

Enjoy!

• PHP is compatible with Unix, Linux, and Windows.
• PHP allows you to organize the code the way you want (start imagining how this could be a good thing)
• PHP has a strong community and has many pre-built open source applications that are waiting for you to intergrate into your project (saving you millions of years sitting in front of your computer)
• Connects easily to a variety of databases
• Its OpenSource, so you got freedom!
• PHP is great for start-ups and side projects because of low-cost, though this should be appealing to everyone.
• PHP code is hidden from web surfers (only html is visible)
• PHP can create .pdf’s and excel files on the fly
• PHP was used to program other awesome and powerful projects (facebook.com, youtube.com, wikipedia.com*)

In conclusion, the correct time to consider using PHP is when you are hungry to create powerful websites!

BlogOrlando 2008 was an awesome event. Just what I needed to motivate me to get back to regularly blogging.

Nice to hear from some other motivated bloggers out there!

I use colorzilla’s “eyedropper” to select a color from a particular point in my browser. Next, I can take that color, adjust the color, and then use my new color in my code. If I’m making an image in Inkscape, I often copy the color’s number into the fill and stroke dialog and adjust the transparency.

If you are trying to get colors that are compatible with your design, install colorzilla now before you mix #7FFF00 with #DF73FF! (chartreuse with heliotrope)

Need colors to match your theme? Instead of picking a random green and purple. Pick a complimentary green and purple out of a picture or webpage. Adjust them to your liking. And go from this…to this! (see below)
