HEllo everyone, i don't know if this is a common problem but i can't seem to understand why it is happening.
I am trying to process a form and have it send the details to an email. Simple enough.
Here is the PHP code for it. When someone fills the form up it shows everything except the senders email. It comes out as unknown sender. Does anyone know how i can fix it?
Thanks a lot to anyone who takes time out to look at this.
