How To use:
First, include the class and initiate it:

Optionally, you can use new Validation(false) to not parse all input data through the xss filter. This is not recommended.

Available functions are:

• xss($string)
• email($string)
• phone($string)
• url($string)
• db_prep($string)

All of the above functions return a boolean value with the exception of xss() and db_prep(). Those two return a modified version of $string.

Here is an example of form validation:

getErrorMessage());}

include("validation.class.php");
$validation = new Validation;

echo "SELECT * FROM users WHERE user='".$validation->db_prep($validation->database_input)."'";
echo "";

if($validation->email($validation->email)) echo "valid email";
else echo "not valid email";
echo "";

if($validation->phone($validation->phone)) echo "valid phone";
else echo "not valid phone";
echo "";

if($validation->url($validation->url)) echo "valid url";
else echo "not valid url";
echo "";
?>


database input:


email:


phone:


url:

A demo of the above test can be found here.

As you can see from the example above, instead of calling $_GET['username'], you can now call $validation->username without worrying about the data being ‘dirty’.

If you have control over both domains, then this may be the ideal solution for you. For example, lets say you have two sites and you need to share data between the sites. Connecting via MySQL could be out of the question. So what do you do now? Create a dynamic javascript include file.

See how that outputs a Javascript array? It will come in handy next.

By including the dynamic.php file as if it were a javascript file, you have imported the data from the other domain without having to use ajax. You can use this to pass any amount of javascript you need. I’m sure if you’re clever you will figure out how to make this into a “mock AJAX” system.
