command line - Using "SET /P" inside an IF statement

Question

I'm creating a batch to turn my laptop into wifi an make my life easier to type lines in cmd each time.

The trouble is the wifi name always get set to key= insted of the one which I enter.

Here is what I did:

@echo OFF
set /p option="Enter 1 to create wifi, Enter 2 to stop wifi "
IF %option% EQU 1 (
    set /p id="Enter wifi Name:"
    set /p key="Set password:"
    netsh wlan set hostednetwork mode=allow ssid = %id% key = %key%
    netsh wlan start hostednetwork
)

IF %option% EQU 2 (
netsh wlan set hostednetwork mode=disallow
)

timeout /t 5

Answer 1

While you shouldn't have any spaces between the switch and the equal sign, or the equal sign and the parameter, the real culprit is because you're using SET /P inside the IF statement.

To correct this, you'll need to do two things:

1. Add Setlocal EnableDelayedExpansion to the top of your batch file, after the @ECHO OFF statement (so that the variables in the IF block can be expanded at execution time).

2. Since we're now using EnableDelayedExpansion, call all your variables using !! instead of %%, such as:
   
   netsh wlan set hostednetwork mode=allow ssid=!id! key=!key!
