error php
// how to display php errors on your browser :
// first step, create an error function :
$errors = array();
// now you have just to insert the function like this :
if (........){
$errors['the_name_of_the_error']='the error message';
}
// example :
// we want to display an error when the user does not correctly fill,
// in the 'password' box when registering on your website :
if(empty($_POST['password']) ||
$_POST['password'] != $_POST['password_confirm']){
$errors['errors']= "You must enter a valid password";
}
