However, until recently it has lacked an elegant way of nesting an image in an anchor tag. I had to resort to manually typing out HTML like this:
<a href="<?=site_url?>/controller/action"><img src="<?=base_url()?>/images/button.gif"></a>
CodeIgniter 1.6 has been released, quickly followed by 1.6.1. This includes an image helper. One is still unable to elegantly link images using CI’s helpers. If you want to be able to do something like this:
<?= anchor( 'controller/action', img( 'images/button.gif' )?>

You could just comment out line 117 in /system/helpers/url_helper.php but that means you are altering CI core, which is not a good idea. For a start it will be overwritten when you upgrade and it is an inelegant hack.

A better bet is to create your own helper file and use it to override CodeIgniter’s one. This is dead-simple, just create a file called MY_url_helper.php in the following location /system/application/helpers/. Note that the MY_ prefix is set in the config.php file under $config['subclass_prefix'] = 'MY_'; so if you have changed that setting you will need to adjust your file-name accordingly.

Then just copy and paste the following in to it:

< ?php  if (!defined('BASEPATH')) exit('No direct script access allowed');

if (! function_exists('anchor'))

{

 function anchor($uri = '', $title = '', $attributes = '')

 {

 	$title = (string) $title;		if ( ! is_array($uri))

 	{

 	$site_url = ( ! preg_match('!^\w+://!i', $uri)) ? site_url($uri) : $uri;

 	}

 	else

 	{

 		$site_url = site_url($uri);

 	}

if ($title == '')

 	{

 		$title = $site_url;

 	}

if ($attributes == '')

 	{

 		// $attributes = ' title="'.$title.'"';

 	}

 	else

 	{

 		$attributes = _parse_attributes($attributes);

 	}

return ''.$title.'';

 }

}

?>

However, I now have Lighty, PHP, and MySQL playing nicely and… it’s fast! This was tested with: Lighty 1.4.18 and PHP 5.2.3_1 on FreeBSD 6.2.For the installation of these programs it is almost a must to install from the latest ports snapshot. Installing from ports allows you to compile with certain options, for example CGI support, and it also ensures you have the very latest release. This is important since even right now the latest PHP5 in ports (5.2.3_1) has security problems, and so too does Lighttpd 1.4.18. Therefore it is vital that these can be updated at the soonest possible time. Personally, I don’t mind a few security niggles, and while Lighty retains a fairly small percentage of the server market it shouldn’t be subjected to bad attacks.

For me, I wanted to use Lighty and PHP with MySQL. The easiest way to install PHP and PHP MySQL support is to just install the php5-extensions. So change to their directory:

cd /usr/ports/lang/php5-extensions

make config

Now choose all the different extensions you want, which would normally include MySQL. When asked about PHP options make sure you enable FastCGI.

    For me I chose to install:

  • CLI
  • CGI
  • Suhosin
  • IPV6
  • FastCGI
  • Path Info

If you don’t want all the fluff you can just change directory to

cd /usr/ports/lang/php5

make config

Choose the options here. In either case after running:

make config

you need to run:

make install clean
