I'm very proud of myself because I found the solution on my own.
I've started using snippets of the message and they would all work separately. That's until I added the part where two variables are one behind the other. I just added a short word in between and it works.
Before:
$message = "Recu informations qualité de " .$nom. " pour le voyage effectué en " .$mois. " " .$annee. ". \n\n Contact: " .$contact. ", \n Supports: " .$supports. ", \n Logements: " .$logements. ", \n Circuit: ". $circuit. ", \n Excursions: " .$excursions. ", \n Guides: " .$guides. ", \n Repas: " .$repas. ", \n Transports: " .$transports. ", \n Note: " .$note. ", \n Commentaire: " .$commentaire. "";
After:
$message = "Recu informations qualité de " .$nom. " pour le voyage effectué en " .$mois. " de " .$annee. ". \n\n Contact: " .$contact. ", \n Supports: " .$supports. ", \n Logements: " .$logements. ", \n Circuit: ". $circuit. ", \n Excursions: " .$excursions. ", \n Guides: " .$guides. ", \n Repas: " .$repas. ", \n Transports: " .$transports. ", \n Note: " .$note. ", \n Commentaire: " .$commentaire. "";
Does someone send me a chocolate medal now?
Cheers,
