Jump to PostI'm assuming that you're using vanilla mysql. Change to mysqli or PDO for binding parameters, then you don't have to worry out escaping input. However you may want to validate input, which is a different matter. Have a look here for built-in validate filters: http://php.net/manual/en/filter.filters.validate.php
