Reply To: image_select value not working

Yes, you can do that. However, because PHP doesn't allow to use same keys in an array, you need to change the selector to something else (while still make it work):

'input_value' => array(
    'input[name=rnr_wr_pagetype]' => 'st2',
    'input[name*=rnr_wr_pagetype]' => 'st3',
),
