I have file which I use for validating which includes the following
function:
function invalidchar($strvalue)
{
if(!ereg("^[[:alpha:][:space:]\'-.]*$", $strvalue)) {
return "*";
}
}
Here is the problem. If I don't use the function, like below, there is no
problem.
if (empty($person)) { $formerror['person'] = "*"; }
elseif(!ereg("^[[:alpha:][:space:]\'-.]*$", $person)) {
$formerror['person'] = "*";
}
If I use the one below it says $formerror['person'] is set, but if I echo it
there is nothing in it. But here is the kicker, I have several other scripts
that use the same function with no problems. In fact, I have another form
which uses the code below with no problems. So I am at a loss as to what the
problem is. I have deleted all other validating except for the one below to
try and narrow this down, but still at a loss. One last thing, if I unset
$formerror['person'] at the end of the code below, it works. So obviously it
has a value - but what is it and how is it getting it?????? Am I just losing
it????
if (empty($person)) { $formerror['person'] = "*"; }
else {
$formerror['person'] = invalidchar($person);
}
Any help before I go insane.
This is the entire code:::
<?
session_start();
if(isset($_SESSION['nodatabase'])) { unset($_SESSION['nodatabase']); }
$databasename = "database";
include_once("constants.php"); // This has the functions in it
if($mysubmit && !$_SESSION['added']) {
$name = slashstrip( $_POST['person'] );
$place = slashstrip( $_POST['place'] );
$comment = slashstrip( $_POST['comment'] );
if (empty($person)) { $formerror['person'] = "*"; }
else {
$formerror['person'] = invalidchar($name);
if($formerror['person']) { $formerror['person'] = "*"; }
}
if (!$formerror) {
// Calls function to write entries to database - which works
if I could get here
$inserterror = writerecord($today, $_SESSION['cfname'],
$person, $place, $comment, $ipaddrs);
if($inserterror) {
$headerror = $inserterror;
}
else { $_SESSION['added'] = True; }
}
else { $headerror = formerrors; }
}
?>
