ereg() dilemma

[rachellara1979]

Hi, new to PHP and to this group, so very sorry if this is simple or
has been covered before. Basically want to check that a user and
password (entered in a previous page) only has characters but the
result of this is that it only ever goes to wrong!!! please tell me
why! I cant figure it out and feel so stupid! I even tried with :

if(ereg("[a-z][A-Z][0-9]", $Pword) && ereg("[a-z][A-Z][0-9]", $User)) {
redirection2();
}
else {
redirection();
}

and that also goes to the wrong.php page (which I put in a following
else), that's why I assumed try checking that it equals 1, but still no
good. HELP ME PLEASE!!

<?php
function redirection2() {
header("location: ok.php");
}

function redirection() {
header("location: wrong.html");
}

$User = $_POST["Username"];
$Pword = $_POST["Password"];

if(ereg("([a-z][A-Z][0-9])", $User, $Pword) == 1) {
redirection2();
}
else {
redirection();
}
?>

You need to learn a bit more about regular expressions.

The expression "[a-z][A-Z][0-9]" matches a single lowercase letter, followed
by a single uppercase letter, followed by a single digit. Any string
containing this combination will pass your test (try "-+= xY2 &/;", for
example -- the sequence "xY2" in the middle is enough to pass your test).

In this case, something like "^[a-zA-Z0-9]+$" would probably work better,
although I don't think it's wise to restrict passwords to alphanumeric
characters only. Why not allow other symbols like /, _, !, @, #, $, %, ^, &,
* as well? And don't names sometimes contain spaces or hyphens?

You can also define minimum and maximum lengths for these strings by
replacing "+" with something like "{4,20}". I'll leave you to figure out how
this all works. The documentation is perfectly clear:

Thank you thank you! :) fixed! I didn't realise the [] and order
made a difference...checking out the link you provided. i agree with
your points about spaces, underscores etc, but that unfortunately isnt
up to me in this instance but ill work out how to use them too. ;)

thanks again :)

I know exactly what it feels when you get help from *kind hearted*
newsgroups guys. Great expression, indeed!

I still remember my older days. Still getting a big deal help.
