Batch - If, ElseIf, Else

Question

Whats wrong with this code?

IF \"%language%\" == \"de\" (
    goto languageDE
) ELSE (
    IF \"%language%\" == \"en\" (
    goto languageEN
) ELSE (
    ech         


        

Answer 1

@echo off
title Test

echo Select a language. (de/en)
set /p language=

IF /i "%language%"=="de" goto languageDE
IF /i "%language%"=="en" goto languageEN

echo Not found.
goto commonexit

:languageDE
echo German
goto commonexit

:languageEN
echo English
goto commonexit

:commonexit
pause

The point is that batch simply continues through instructions, line by line until it reaches a goto, exit or end-of-file. It has no concept of sections to control flow.

Hence, entering de would jump to :languagede then simply continue executing instructions until the file ends, showing de then en then not found.

Answer 2

@echo off title Test
echo Select a language. (de/en) 
set /p language=

IF "%language%" == "de" (
   goto :languageDE 
   ) ELSE IF "%language%" == "en" ( 
   goto :languageEN 
  ) ELSE (
   echo Not found. )

:languageDE 
   echo welcome ,you selected the jarmni langauge 
   goto :eof

:languageEN 
   echo welcome ,you selected the english langauge 
   goto :eof

Answer 3

batchfiles perform simple string substitution with variables. so, a simple

goto :language%language%
echo notfound
...

does this without any need for if.

Answer 4

@echo off
color 0a
set /p language=
if %language% == DE (
    goto LGDE
) else (
    if %language% == EN (
    goto LGEN
    ) else (
    echo N/A
)

:LGDE
(code)
:LGEN
(code)

Answer 5

Recommendation. Do not use user-added REM statements to block batch steps. Use conditional GOTO instead. That way you can predefine and test the steps and options. The users also get much simpler changes and better confidence.

@Echo on
rem Using flags to control command execution

SET ExecuteSection1=0
SET ExecuteSection2=1

@echo off

IF %ExecuteSection1%==0 GOTO EndSection1
ECHO Section 1 Here

:EndSection1

IF %ExecuteSection2%==0 GOTO EndSection2
ECHO Section 2 Here
:EndSection2

Answer 6

@echo off

set "language=de"

IF "%language%" == "de" (
    goto languageDE
) ELSE (
    IF "%language%" == "en" (
        goto languageEN
    ) ELSE (
    echo Not found.
    )
)

:languageEN
:languageDE

echo %language%

This works , but not sure how your language variable is defined.Does it have spaces in its definition.
