Verificarea datelor primite prin $_POST

[Gabriel Puscuta]

O varianta simpla ar fi:

class Input{
    
    static public $index;
    
    public function post($index=NULL){
        self::$index = $index;
        
        if($index == NULL){
            $toret = array();
            
            foreach($_POST as $key => $value){
                $toret[$key] = Input::sanitize(trim($value));
            }
            
            return $toret;
        }
    }
    
    public function sanitize($var,$santype=3){
        switch($santype){
            case 1:
                return strip_tags($var);
            case 2:
                return htmlentities(strip_tags($var), ENT_QUOTES, 'UTF-8');
            case 3:
                if(!get_magic_quotes_gpc())
                    return addslashes(htmlentities(strip_tags($var), ENT_QUOTES, 'UTF-8'));
                else
                   return stripslashes(htmlentities(strip_tags($var), ENT_QUOTES, 'UTF-8'));
            break;
        }
        return FALSE;
    }
    
    public function valid_input($post,$mandatory){
        foreach($mandatory as $key){
            if(!isset($post[$key])){
                return FALSE;
            }
        }
        
        return TRUE;
    }
    
}
$post = Input::post();
if($post){
    $mandatory = array('field');
    if(!valid_input($post,$mandatory)){
          return FALSE;
    }
}
