allow terawallet topup conditionally

@kmalber You can restrict wallet top-ups using filter

woo_wallet_is_enable_top_up

Thanks Subrata. In case it helps anyone else, here’s the code I’m using:

add_filter('woo_wallet_is_enable_top_up',?'ka_limit_topup_to_neg_bal');

function?ka_limit_topup_to_neg_bal($enable_flag){

????$user?=?wp_get_current_user();??????

????$current_user_id?=?$user->ID;

????$wallet_bal?=??woo_wallet()->wallet->get_wallet_balance($current_user_id,?'');?

????$enable_flag?=?FALSE;????//initialize?to?not?allow?top_up?unless?debit?balance

//?if?a?debit?balance?exists,?allow?payment

????if?($wallet_bal<0)?{

????????$enable_flag?=?TRUE;

????}?

????return?$enable_flag;????????

}
