Conflict with “add_fee” function – unable to add discount

  • Hello,

    I was using $cart->add_fee to add discount (based on custom logic). After enabling plugin it stopped working.
    Adding discount is hooked with add_action('woocommerce_before_calculate_totals', 'discount_based_on_trade_account');.

    Any tip how to get it working back is appreciated

  • Hi.
    You need debug step by step to get exactly bug. In this plugin, we don’t use woocommerce_before_calculate_totals hook.

    Hi,
    Isn’t it exactly bug? $cart->add_fee worked and stopped working after activating plugin. Is there any information I can share with you that would be helpful in troubleshooting?

    No, I want to know bug in which line, type of bug,… Are you web developer? Do you use some debug tools like Query monitor plugin?

    The problem is that there is no bug/warning appearing. The only effect is that coupon is not applied.

    I’m a developer. I’ve used Query monitor but it showed no errors.
    When I’ve added var_dump($cart) just before $cart->add_fee there are warnings Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/fieldtiles/wp-content/themes/fieldtiles/inc/functions_coupon.php:43). Do you think is somehow related?

    Are there any actions I could perform to obtain more information that would be helpful?

    No, this warning mean you show data in header area. I think line-43 is where you write var_dump().

    To difficult to help you when I don’t know your code.

    Yes, line-43 is where I wrote it. I was asking because this warning appears only when plugin is activated.

    Here’s the code: https://bitbucket.org/robert-adchitects/field-tiles-discount/src/master/functions_coupon.php

    Currently, this function is not exist, may be you don’t send all code https://prnt.sc/t1srr2
