Every time when your email cannot be delivered, the SMTP server sends you a notification, which includes a standard error message, associated with the real problem. Each code is composed of three digits (X.X.X). The first digit gives the status of the email message: Continue reading

I can’t remember what all I looked at for references, but this completed tool will generate the SQL commands necessary to convert your database, tables and fields from any collation and character set into another.
It goes without saying to make a backup of your database before running such commands. If you don’t make a backup first, shame on you 😛 Continue reading
Nothing too complicated 😉
-R > recursive (includes all folders/files)
–reference=. > get owner:group from the current folder (eg: single dot)
. > start in current directory
chown -R --reference=. .
This comes in pretty handy when migrating sites using gzipped archives 😀
Compress:
tar -zcvf myarchive.tar.gz ./
Extract:
tar -zxvf myarchive.tar.gz
That’s all folks 🙂
Goes well with recursive chown when moving files between servers!
This function will convert hexadecimal colors with a length of 6, 3, 2, or 1 into their RGB decimal equivalents. If a value cannot be converted, it defaults to black…
function hex2rgb($hex = NULL) {
preg_match('/^#{0,1}([0-9a-f]{1,6})$/i', $hex, $matches);
if ($hex[0] == '#') $hex = substr($hex, 1);
$length = @strlen($matches[1]);
switch ($length) {
case 6:
$rgb = array($hex[0] . $hex[1], $hex[2] . $hex[3], $hex[4] . $hex[5]);
break;
case 3:
$rgb = array($hex[0] . $hex[0], $hex[1] . $hex[1], $hex[2] . $hex[2]);
break;
case 2:
$rgb = array($hex[0] . $hex[1], $hex[0] . $hex[1], $hex[0] . $hex[1]);
break;
default:
$hex = ($length == 1) ? $hex . $hex : 0;
$rgb = array($hex, $hex, $hex);
break;
}
return array(
'r' => hexdec($rgb[0]),
'g' => hexdec($rgb[1]),
'b' => hexdec($rgb[2])
);
}
Short, simple and sweet 🙂
Out of the box, CodeIgniter has a good CAPTCHA helper to use in your web applications. Here is a simple example of how to get a new CAPTCHA image without having to reload the page 😉
Basic Controller
class Welcome extends CI_Controller {
private $captcha_path = 'assets/img/captcha/';
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->load->helper(array('captcha'));
$captcha = create_captcha(array(
'word' => strtoupper(substr(md5(time()), 0, 6)),
'img_path' => $this->captcha_path,
'img_url' => $this->captcha_path
));
$data = array(
'captcha' => $captcha
);
$this->session->set_userdata('captcha', $captcha['word']);
$this->load->view('welcome', $data);
}
}
The View (jQuery used for UI buttons and altering CAPTCHA image ‘src’ attribute)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.23/jquery-ui.min.js"></script>
<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/themes/blitzer/jquery-ui.css">
<script>
$(function(){
$('#new_captcha').button({
text: false,
icons: {
primary: 'ui-icon-refresh'
}
}).click(function(event){
event.preventDefault();
$(this).prev().attr('src', 'welcome/new_captcha?'+Math.random());
});
});
</script>
<?php echo $captcha['image']; ?>
<a href="#" id="new_captcha">Reload CAPTCHA</a>
Modified Controller Continue reading
In a lot of my controllers, I use pagination along with the HTML <base> tag’s href attribute for relative link URLs.
Example URL: http://www.domain.com/admin/users/index/pagination_offset
HTML Base tag: <base href=”http://www.domain.com/admin/”>
What this means, is I usually have to build pagination’s base_url option based on where I am and what information is being passed in the URI. A lot of times it ends up looking something like…
$this->load->library('pagination', array(
'base_url' => $this->uri->segment(2) . '/' . $this->uri->segment(3) . '/' . $this->uri->segment(4),
'total_rows' => $total_rows,
'per_page' => 20,
'uri_segment' => 4
));
What I decided to do what extend the core CodeIgniter URI class to provide a basic slice method to grab a chunk of the URI by applying PHP’s array_slice function to the segments property of the URI class. Continue reading
Some browsers do not support the placeholder attribute added in HTML5. This attribute is useful for field hinting such as input formats for dates, phone numbers, and the like. If you see text in the field below, your browser supports placeholder, if not, add the code below to mimic the behavior 😉
Example field:
JavaScript (jQuery) workaround: Continue reading
Load the helper:
$this->load->helper(‘database’);
Call the function:
$enums = field_enums(‘table_name’, ‘field_name’);
Compliments my US State List 😉 Continue reading
