preg_match question

[dmcinnis]

Anyone know the problem with this snippit. I am trying to make sure that the value $pwd1 contains only letters and numbers.

if (preg_match ("/^{[a-z0-9]+S/",} $pwd1)) {
// code here
}

Thanks,

David

This was probably just a careless mistake, but if you replace the "S" with "$", it should work.

Still giving me problems.

Here is my code

if (preg_match ("/^{[a-z0-9]+$/",} $pwd1)) {
$errormsg .= "<LI>INVALID PASSWORD: Password may contain only letters or numbers.\n";

}

Interesting. I did not think that I could post html code to this board. &lt;LI &gt; and &lt;BR &gt were accepted above.

The code you use now is sort of backward.

change "(preg_match ("/^{[a-z0-9]+$/",} $pwd1))" to "if (!ereg_match ("/^{[a-z0-9]+$/",} $pwd1)) {", and it should work properly. If not, I don't know what the problem is.
