Php联系表格未被收到

Question

今天下载了一个基本引导网站的模板，在自定义并上传到我的主机之后，我意识到联系表单虽然说它已被发送，但不会发送电子邮件。

我从未做过任何PHP编码，也不知道任何帮助的语言！

这是php的代码

# Try to find Lua or LuaJIT depending on the variable ENABLE_LUAJIT.
# Sets the following variables:
#   LUA_FOUND
#   LUA_INCLUDE_DIR
#   LUA_LIBRARY
#

SET (LUA_FOUND FALSE)

SET (LUA_INTERPRETER_TYPE "")

SET (LUA_INTERPRETER_TYPE "LuaJIT")
SET (LUA_LIBRARY_NAME luajit-5.1)
SET (LUA_INCLUDE_DIRS /usr/include/luajit-2.0 /usr/local/include/luajit-2.0)

FIND_PATH (LUA_INCLUDE_DIR lua.h ${LUA_INCLUDE_DIRS} 
            HINT ${LUAJIT_INCLUDE_DIR_HINT}/include)
FIND_LIBRARY (LUA_LIBRARY NAMES ${LUA_LIBRARY_NAME} PATHS /usr/lib /usr/local/lib
            HINT ${LUAJIT_INCLUDE_DIR_HINT}/bin)

#...
