I am wondering if anyone out there can help with my form Validation Please?
I am having a few problems trying to synchronized out how certain bits of the actual structure of the script works together.
<?php
$flag="OK"; // This is the flag and we set it to OK
$msg=""; // Initializing the message to hold the error messages
if(isset($_POST['Send'])){
$key=substr($_SESSION['key'],0,4);
$num_key = $_POST['num_key'];
if($key!=num_key){
$msg=$msg."Your Key not valid! Please try again!<BR>";
$flag="NOTOK";
}
else{
$msg=$msg."Your Key is valid!<BR>";
$flag="OK";
}
}
$email=$_POST['email'];
echo "Your Email: ".$email." is";
if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)){
$msg=$msg."Invalid email<BR>";
$flag="NOTOK";
}else{
$msg=$msg."Valid Email<BR>";
$flag="OK";
}
$password=$_POST['password'];
if(strlen($password) < 5 ){
$msg=$msg."( Please enter password of more than 5 character length )<BR>";
$flag="NOTOK";
}
if($flag <>"OK"){
echo "$msg <br> <input type='button' value='Retry' onClick='history.go(-1)'>";
}else{ // all entries are correct and let us proceed with the database checking etc …
}
function spamcheck($field)
{
$field=filter_var($field, FILTER_SANITIZE_EMAIL);
if(filter_var($field, FILTER_VALIDATE_EMAIL))
{
return TRUE;
}
else
{
return FALSE;
}
}
if (isset($_POST['email']))
{//if "email" is filled out, proceed
$mailcheck = spamcheck($_POST['email']);
if ($mailcheck==FALSE)
{
echo "Invalid input";
}
}
?>
the problem, when email valid, password valid, though key is invalid the warning of key disappear, it mean passed too... and also the spamcheck doesn't look work..
