I need a really simple regex, but I don't want to bother looking in to it for 1 thingie.
it basicly needs to check if a string has 1 dot in it not more not less and if after that dot there are 1-5 random Letters not numbers.
"^\\.[a-zA-Z]{1,5}$"
Couple things I'm assuming:
PCRE, single line, and nothing before or after the string you are validating.
My test cases:
[code]
.words - validates
.whoop - validates
word.words - fails
this.is.atest - fails
this.is.a.test - fails
teh - fails
.cakes - validates
[/code]
Regex seems pretty simple
Ooh how would I let this pass ?
word.words - fails
and still letting this fail :
this.is.atest - fails
this.is.a.test - fails
edit :
Sorry for not being clear enough.

Just gotta stick a [a-zA-Z]* on the front of it, like so: "^[a-zA-Z]*\\.[a-zA-Z]{1,5}$"
Mind you this would still let stuff like ".words" validate, so let me know if that's not what you want.
[QUOTE=VoiDeD;17789353]"^[a-zA-Z]*\\.[a-zA-Z][b][u]{1,5}[/u][/b]$"[/QUOTE]
How did I miss this? D:
Oke well I understand it now only I do not understand this : "^[a-zA-Z][b]*\[/b]\.[a-zA-Z]{1,5}$"
What does this do ?

In the actual regex, that will appear as a single backslash. As you're entering it into some sort of language (C++, Lua, PHP, whatever), you must escape the backslash with another one, as backslashes are considered escape characters in many languages.
I've set up a simple script to test the regex but it isn't outputting anything :S
[php]
<html>
<head>
<title>Wassup</title>
</head>
<body>
<form name="input" action="test.php" method="post">
validate
<input type="text" name="user" />
<input type="submit" value="Submit" />
</form>
</body>
</html
<?php
if(isset($_POST['user']))
{
if(preg_match("/^[a-zA-Z]*\\.[a-zA-Z]{1,5}$/",$_POST['user']))
{
echo "Valid !";
} else {
echo "Non Valid !";
}
}
?>
[/php]
</html typo
And you should move it to before the end html tag anyway
stupid type :(
