INSERT into Roomid,name,id1,id2 values (' 1 ', ' 232 ', ' $_post[id1] ', ' $_post[id2] ')

$_POST[ID1],$_POST[ID2] Pass over is the value, not the ID, how to deal with it here?

------Solution--------------------
$_POST[ID1],$_POST[ID2] is the concept of how a value is not an ID.

is not the value in SQL is the variable name, not the value AH.
INSERT into Roomid,name,id1,id2 values (' 1 ', ' 232 ', ' {$_POST[ID1]} ', ' {$_post[id2]} ')

Or

INSERT into (ROOMID,NAME,ID1,ID2) VALUES (' 1 ', ' 232 ', ' ". $_post[id1]." ', ' ". $_post[id2]." ') "
------Solution--------------------
What do you mean??
------Solution--------------------
The IDs of the two tables cannot be inserted at the same time in an INSERT statement, and should be done in step.
If the ID is set to Auto_increment, then no ID is inserted, and duplicate values cannot be interpolated.
If not set to self-growth:
sql = "INSERT into the Roomid,name,id1" values (". $_post[' Roomid ').", ' ". $_post[' name ']." ', ". $_post[' Id1 '].") ";
When querying, you can do multiple table queries.

------Solution--------------------
$_POST[ID1],$_POST[ID2] It was his value.
