preg_match not doing much

[shotza]

Hi folks

I'm very new at php and writing code in general so please be gentle with me :)

I'm trying to write an if statement that will check for numeric input unfortunatley the code isnt trapping any text input.

The statement is as follows:

if (!preg_match('/[[:^digit:]]/', $seconds)) {
echo "<h1>Laptime must contain numeric values only! </h1>
<p>Please hit the <b>Back Button</b> on your browser to re-enter information";
exit();
}#end if

Any pointing out of stupid mistakes would be greatly appreciated!

POSIX bracket-expressions are not valid in PCRE; try [tt]/^\d+$/[/tt] to match all digits.

That worked a treat - very much appreciated :)
