hi,
my problem is this: i'm using a while loop to check elements in an
Array for valid email syntax. if $User[0] is a valid email address but
$User[1] is not, the code for $User[0] is still executed before the die
statement. i need my loop to finish checking ALL array elements for
validity, and to then die BEFORE any further code is executed. here's
what i have now (it doesn't work):
//loop to check for bad email addresses:
$j = 0;
$flag = 0;
while ($j < count($User)){
if
(($User[$j]!="")&&!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*$",
$User[$j]))
{
$flag = 1;
$errorNo = $j + 1;
}
//die if flag is 1
if ($flag = 1) {
die ("<p align='center'><b>Email #$errorNo is not a valid e-mail
address!</b><br><br><br><a
href='javascript:window.history.back();'>Please return and correct
this.</a></p>");
}
else {
continue...
}
any suggestions would be great!
thanks much,
tom
