In our series of post recently ‘on the website check’ we portray everyday problems, we have found in our Web site checks and demonstrate solutions. A contact form is useful and provides a convenient way for the company to contact, such as when he just sits on his own PC not the users. “However, experience shows that often forget” is to enter the E-Mail address or a message body (finally the receiver must know so well what I want from him and how he can reach me!”). No X make for a U – plausibility control each contact form should contain a plausibility check, which checks whether all required inputs have been made before sending can be correct. This protects also against clowns, the like to empty”contact forms send off. Ideally the plausibility check serves two, both the user and the provider.
When in form fields such as for the entry of the name, only letters, and not numbers be approved and vice versa for a form field, such as a phone number is obtained, only numbers and no letters are allowed, serves this as a help for the users and also reduces the spam payload for the provider. Spam through contact forms so far, so good. Were it not for the bots. Derived from the term robot, bots-computer programmes are meant, named the self-employed largely repetitive tasks work without being dependent on an interaction with a human user such as automated filling out contact forms with more or less meaningful content. Most bots are the fields of contact forms now capable of correctly”to fill in the field, which is an E-Mail address to enter any email address and to ensure that the plausibility of the entries. CAPTCHAs – a solution with barriers to reduce the exposure to unwanted advertisements via contact forms through such bots are often so called CAPTCHAs used.
