Problem:

I am looking for after step 2 is submitted/processed and on step 3 I would be allowed to change the pricing. This would have the changed pricing shown in step 3 rather than after step 3 is submitted/processed. In the processing of changing this price. I've tried the above methods to change the pricing on the transaction, however, it remains the same.

Please let me know if I can provide any additional information.

Hi @tfont I provided some feedback on https://gist.github.com/tfont/4045cdd1736fa853bd9bd60b7d6333d9, although that might not be the cause of your problem.

@mnelson4 so far no. I left an update on the GIST. I am trying to figure out the entire EE_SPCO_Reg_Step_Attendee_Information class and its interactions to better debug my problem.

hi @tfont I'm having difficulty following what you're asking on that gist. Can you please show your entire plugin code? That would help me identify the problem

Sadly, not possible. It's pretty straightforward:

When submitting on step 2 which then goes on to step 3. How would one change the price of a transition (item) that will display this price change on step 3 and onwards?

@tfont it's much harder for us to help debug your code if you don't show us what it is.

Here is a code snippet that I've confirmed changes the transaction's total and the amount show during SPCO's payment options step (what you're calling step 3):

add_action('AHEE__Single_Page_Checkout__after_attendee_information__process_reg_step', 'custom_hook', 10, 1);
function custom_hook(EE_SPCO_Reg_Step_Attendee_Information $data)
{
    $purchases = $data->checkout->transaction->items_purchased();
    $first_item = reset($purchases);
    //we need to edit the sub-item's unit price, as
    //the line item's total is calculated from its sub-items
    $children = $first_item->children();
    $child_line_item = reset($children);
    $child_line_item->set('LIN_unit_price', 10);
    $data->checkout->cart->get_grand_total()->recalculate_total_including_taxes();
    $data->update_checkout();
}

Added this as a new code snippet on https://github.com/eventespresso/ee-code-snippet-library/blob/master/checkout/mn_spco_change_line_item_before_payment_options_step.php

If you would like more help, please provide the code you're using.
