custom page and validate the input

[carleton]

I am working on developing a custom page that needs to validate the input before continuing. I have read the OptionInstall2 page a number of times now and simply do not understand how to get the validation function called. Here is what I have:

Here is my init:

code:


Function .onInit

!insertmacro MUI_INSTALLOPTIONS_EXTRACT_AS "assets\RegForm.ini" "RegForm"

FunctionEnd

This is where I am calling the page:

code:


!insertmacro MUI_PAGE_LICENSE "..\licence\Licence.txt"



LangString REGFORM_TITLE ${LANG_ENGLISH} "Registration."

LangString REGFORM_SUBTITLE ${LANG_ENGLISH} "Enter your Unlock Key."

Page custom RegPageShow



!insertmacro MUI_PAGE_DIRECTORY

The function calls:

code:


Function RegPageShow



   !insertmacro MUI_HEADER_TEXT "$(REGFORM_TITLE)" "$(REGFORM_SUBTITLE)"

   !insertmacro MUI_INSTALLOPTIONS_DISPLAY "RegForm"



FunctionEnd



Function RegPageValidate



  ReadINIStr $R0 "RegistrationForm" "Field 4" "State"

  StrCmp $R0 "" 0 +3

    MessageBox MB_ICONEXCLAMATION|MB_OK "Please enter your name."

    Abort



FunctionEnd

I see your function called RegPageValidate, but when is it executed?
Try move the contents of RegPageValidate into RegPageShow...

put the validation function on the custom page definition

code:
Page custom RegPageShow RegPageValidate

Thank you! I did keep digging through the documentation last night and finally found the answer, I am still a bit new to working with Open Source project's, man what a different mindset. The answer is there, you just have to dig for it at times!
