I am creating a web interface for registering entries for the annual Jr.
High Music Festival at my college. I am currently in the process of
writing a page that will validate school registration information. I
have created a school registration page with forms and I am sending the
data collected to a script called validate.php. validate.php (much as
the name suggests) checks the information submitted for validity and if
it finds it so, will send it somewhere else for entry into a database.
The problem is this: I want to use pattern matching to make sure there
are no undesirable characters in the phone number fields. To facilitate
this, I have set up three text boxes; one for area code, one for prefix,
and one for the last four digits (I can't remember what that's called
ATM.) When validate.php is called, each of these values (as well as a
few others) are incorporated as variables into the script. The problem
is that my pattern matching bit doesn't work. I inserted a 'b' at the
end of the area code; validate.php was supposed to spit out an error,
but it didn't. Here's the script:
<html>
<body>
<?
$schoolname = $_POST['schoolname'];
$directorname = $_POST['directorname'];
$parea = $_POST['parea'];
$pprefix = $_POST['pprefix'];
$prest = $_POST['prest'];
$farea = $_POST['farea'];
$fprefix = $_POST['fprefix'];
$frest = $_POST['frest'];
$emailaddress = $_POST['emailaddress'];
if (preg_match("/D/", $parea, $array))
print "Error found in phone number area code information. Possible
typo?<br>\n";
if (preg_match("/D/", $pprefix, $array))
print "Error found in phone number prefix information. Possible
typo?<br>\n";
if (preg_match("/D/", $prest, $array))
print "Error found in the last four digits of phone number
information. Possible typo?<br>\n";
if (preg_match("/D/", $farea, $array))
print "Error found in fax number area code information. Possible
typo?<br>\n";
if (preg_match("/D/", $fprefix, $array))
print "Error found in fax number prefix information. Possible
typo?<br>\n";
if (preg_match("/D/", $frest, $array))
print "Error found in the last four digits of fax number area code
information. Possible typo?<br>\n";
?>

<?
print "School Name: $schoolname<br>\n";
print "Director's Name: $directorname<br>\n";
print "Phone Number: $parea-$pprefix-$prest<br>\n";
print "Fax Number: $farea-$fprefix-$frest<br>\n";
print "Director's Email: $emailaddress<br><br><br>\n";
include("registerschool.php");
?>
</body>
</html>
Can anyone help me with this?
