Hello all, It's my first time here, I hope you will be indulgent. I am trying to create a contact form in php, using something that a former employee at my company has written for another website. Please note that I have no knowledge whatsoever of php (except what I've learned while creating it...). Here is the code I am working with. Can you go through and let me know if see anything that seems off to you? Thank you very much! <?php /* ******************************************************************************************** CONFIGURATION ******************************************************************************************** */ // destinataire est votre adresse mail.
