codeigniter has convenient way repopulate field on validation failure

set_value()

thanks.

you give set_value() second parameter initial value on loading.

i using @ supress errors if piece of data not exist

set_value('input_name',@$input_value); 

for this, form element prefilled $input_value if exists
