December 5, 2008 – 1:00 pm
  1. Sanitizing and validating email syntax 
    $email = $_POST['email']; //getting the posted email
//sanitizing the email using FILTER_SANITIZE_EMAIL
//removes all illegal e-mail characters from a string
$email=filter_var($email, FILTER_SANITIZE_EMAIL);
//validating the email using FILTER_VALIDATE_EMAIL
//validates e-mail returning true if valid and false if invalid
(filter_var($field, FILTER_VALIDATE_EMAIL)) ? TRUE : FALSE;
  2. Creating a function to validate and sanitize 
    function check($email)  {
     $field=filter_var($field, FILTER_SANITIZE_EMAIL);
     return (filter_var($field, FILTER_VALIDATE_EMAIL)) ? TRUE : FALSE;
}

    Usage:

    $email = $_POST['email'];
if (check($email)==TRUE){
//send email
}else{
echo "Invalid email!";
}

Ternary Conditionals

December 3, 2008 – 1:01 pm

I know most of you allready use them, but there are still people that don`t know about them, so to make the following tutorials easyer, I`ll do a small example.

First of all you must know that all you will see here is a simpler way to write not so complex if statements.
Traditional way:

if (condition) {
    echo "true";
} else {
    echo "false";
}

The shorter way:

echo (condition) ? "true"  : "false";

Another example:

if (date("m")<12) {
    $var = 12-date("m") ." months till december";
}else{
    $var = "It`s December";
}
echo $var;

The shorter way:

$var = (date("m")<12) ? 12-date("m")." months till december" : "It`s December";
echo $var;

I hope you got it and this will make easyer for you to undersand the following tutorials.
