The Code
Our code that actually tests the form input to validate and process is as follows:
<html><head><title>Your Suggestions</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"></head>
<body bgcolor="black" text="white">
<center>
<?php
if(trim($fName) ==""){
$missing = "<p>The <b>First Name</b> has not been provided.";
}elseif(!preg_match("/^\w+$/", $fName)){
$missing .= "<p><b>First Name</b> contains invalid character(s)";
}
if(!preg_match("/^\w+$/",$lName)){
$missing .= "<p>The <b>Last Name</b> contains invalid character(s)";
}
if(!preg_match("/^(\w+)\@(\w+)\.(\w){2,3}$/",$eAddress)){
$missing .= "<p>Invalid <b>Email Address</b> Provided.";
}
if(trim($suggestion) ==""){
$missing .= "<p><b>Suggestion</b> is blank.";
}
if(trim($missing) != ""){
print "<p>There are a few problems with your data entry:</p>". $missing;
} else {
print "<h2>Thank You</h2>".
"<p>Hello <b>". $fName . " " . $lName . "</b><p>Your suggesstions state that".
"<br><b>$suggestion</b>\. Your email address <b>".
$eAddress . "</b> is valid";
}
}
?>
<center>
</body></html>
