Ook is het niet handig om je mail-fucntie te onderdrukken. En ik raad aan om hier ook een if-else statement in te bouwen. het wil wel eens gebeuren dat mail() soms een false geeft, en ook dát wil je graag opvangen.
Zie ook je PM van huishoudelijke aard die ik je zo stuur.

het script werd gedownload van https://code-boxx.com/simple-php-reservation-system/
Idem dito voor de rest in de connect.
Je hebt het zelf verkeerd ingevuld.
