allowing space in textfield

[shakeit]

Hello everybody, I have a little issue regarding chars and signs that are aprooved in a text string.

 

I want to check the field $name to contain only small and big letters which is usual in a name. But it happens that some people have two names, e.g. one main and one middle name. So I want to allow the user to write both names in one text field, i.e. by using space between them, for example: Jon Thomas. How do I add the space character in the code below in $goodChars, if it is possible?

 

Thanx very much in advance and I hope you understand the problem description :-)

 

----------------------------------------------------------------------------------

public function validateName($name)

{

 

$goodChars = "^[a-z_A-Z]+$";

 

if( ereg("$goodChars",$name) && strlen($name) > $nameLengthMIN )

{

 

return true;

 

}

else

{

return false; //Only A-E and -

}

 

}

---------------------------------------------------------------------

You could simply add a space inside the square brackets. But I think you need to change it a bit, 'cause now a username could contain only an underscore (or more). Do you want an underscore to be allowed at all? If you want the name to either be pure a-zA-Z or a-zA-Z, then one underscore or space, and then a-zA-Z again, this regex would work (change ereg to eregi to make the check case insensitive):

 

^[a-z]+([ _][a-z]+)?$

Hmm.. no i do not want the underscore in the name, that was my bad, i didnt even notice that, heheh... I only want, small letters a to z, big letters A to Z and space.

 

so is this right then:

 

^[a-z]+([ ][A-Z]+)?$

Yep, as long as you use eregi. And it's a bit confusing to use both a-z and A-Z when the search is case insensitive. I would stick with lowercase letters (just for the looks - it won't change any functionality in the script).

[shakeit]

Okey , so I can set all of the letter to lower case in the code AND change ereg to eregi and still use both small and big letters? Thanx man...

Correct
