[SOLVED] Allow one space between words?

[pianoman993]

Hello there PHP experts. I have a small expression that checks to make sure the given string has Only alpha characters, digits, underline or dash characters. However, would it be possible to edit it to allow one space between words?

 

Here is what I've got:

'/^([a-z0-9])([a-z0-9_\-])*$/ix'

 

Example "Example String" (the expression allows one space between example and string)

 

An even more adventurous example: "Another Example String" Still allows a space between words

 

If anyone has any ideas please post!

Thank you for your time!

You might want to post your current expression.

I figured you'd say that as soon as I posted it. *Edited*

Thanks for the speedy response

You mean something like this?

 

$str = 'Another Example String 1_2-3';
echo $str . "<br />\n";
if (preg_match('#^(?:[\w-]+ ?)+$#', $str)){
    echo 'Legal format!';
} else {
    echo 'Illegal format!';
}

I think that did that trick! And that does everything the regular expression accomplished plus spacing correct?

It takes spacing into account. Have you not tried it out?

Yup, works like a charm. You're a genius!

The pattern could also be:

 

'#^(?:[\w-]+ ?)*$#'

Note the * instead of the + after the closing non-capturing bracket. Either version seems to work though.
