A regular expression that validates a given domain without its top level domain. I didnt need to validate the tld because this comes from a selectbox, so its predefined and always valid. The http protocol or the second level domain www. are both optional, it can be written or not.

$regex = "/^(?:(http:\/\/)?)(?:(w{3}\.)?)([A-Z0-9\-".utf8_encode("äÄöÖüÜ")."]{3,})$/i";
if(!preg_match($regex,$domainname)) {
	return false;
}

So the string can look like this:
http://www.liquidbass or www.liquidbass or http://liquidbass

detailed Description:

/^

This is the beginning of the regex. The ^ is used for searching all matches from the beginning of the given string.

(?:(http:\/\/)?)(?:(w{3}\.)?)

Here we have the optional protocol and the optional second level domain www. …

([A-Z0-9\-".utf8_encode("äÄöÖüÜ")."]{3,})

This part of the regex allows all characters from a to z, hyphens and all numerics from 0 to 9.
Additionally german special chars are allowed too.
All these possible characters must match a stringlength of minimum 3.

$/i

the dollar stands for the strings end, so it would be searched for matches from beginning to the end.
the /i stands for case sensivity – the given string can be in capital letters or in lowercase.

This is an easy way to truncate strings without cutting words after n characters.

bad one:
Lorem ipsum dolor sit amet, hy…

good one:
Lorem ipsum dolor sit amet, hymenaeos …

$string = "Lorem ipsum dolor sit amet, pellentesque wisi ut congue eget quam.";
$strLength = 30;
echo substr ( $string, 0, strrpos ( $string, ' ', - ( strlen ( $string ) - $strLength ) ) );

I have searched for a long time until i found the reason why i couldnt make a pageTitle multilingual in a view or in an element.

First I tried to edit the title in this way and became unhappy because it was written in the content area of my page and not in the titletag.

$this->pageTitle = __('new PageTitle');

The second parameter “true” will avoid displaying the text directly.

$this->pageTitle = __('new PageTitle', true);

So, when you write it in this way, it works!

I wanted to install the prototype framework with the scriptaculous effects to my cakePHP Application, but after uploading the prototype files into the webroot/js folder and linking them in the layout, i got a failure message like “Undefined variable: javascript”.

This variable has to be defined in the Applications Helper, so you can put this line of code in your AppHelper class. If you dont know what to do: create a file named “app_helper.php” in your /app folder and insert these lines of code.

class AppHelper extends Helper {
	var $helpers = array('Html','Javascript','Ajax');
}

The $javascript variable is now available and you can insert your javascript files (the prototype framework in my excample) like this in the head of your layout.

		echo $javascript->link('scriptaculous/lib/prototype');
		echo $javascript->link('scriptaculous/src/scriptaculous');

		// Scripts from a view
		echo $scripts_for_layout;
