wrong info?

 

If the user does not fill in all required fields or enters an invalid email format I want to avoid opening my registration success page because it is all filled out to prompt on a successful registration.

you can use the following regex pattern to validate emails

$pattern = "#^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$#";

note i use # as a delimiter.

 

an example

$email = "bad email";
if (preg_match($pattern, $email)){
echo "good email";
else {
echo "bad email";
}

 

output: bad email

 

sorry forgot other part.

 

 

if you want to test for empty fields, use the empty() function, IE

if (empty($field)){
echo "field is empty. Fail!";
exit();
}

Hi Mike,

 

That part of the code is actually working fine, my question is How do I kill the script from opening the reg_success page if the user doesn't enter all required info or do i need to process the register page on it;s on page then open the reg_success page?

 

Thanks again

if (isset($_POST['submit']))

{

//check for data

if ($_POST['username'] == '')

{$username_error= 'fill in you user name';}

else

{$username=$_POST['username']; $error=1;

//clean form input data here

}

// do an if/else for each form widget

}

 

if (!isset($_POST['submit'] || $error==1)

{

//do your form

echo $username_error;// only shows if it has value...so wont show on the !isset

echo "<input name=username value=\"$username\">";//note the var in user name-this repopulates the widget if there is an error but the names WAS filled out and the error is elsewhere

// do this for all errors and widgets}

}

else

{

//do your registration stuff

// then thank the registrant or whoever and what ever they did

}

Thanks , but I don't understand anything you have just posted, sorry.  All I want to to do is show a registration page after successful registration that's all.. If any fields are left blank or the email format was entered correctly I don't want the user to see the reg_success page.
