Creating an override custom error message

[Jack Ball]

Hi,

I am wanting to change the current error message “coupon ‘…’ will be applied when its conditions are met” for all my coupons, I know I can do itin the front end however I have many coupons and are continually adding them, is there a way to change it?

You can use the ‘woocommerce_coupon_error’-filter for that. You can take a look at the source code of our plugin for inspiration.

What directory is the source code for this in your plugin?

/pro/plugins/WJECF_Pro_Coupon_Queueing.php

Looking further, I think the WC filter to override our meta-value ‘_wjecf_enqueue_message’ would be easier to implement. Something like this:

add_filter(
  'woocommerce_coupon_get__wjecf_enqueue_message',
  function( $value, $coupon ) {
    return 'THE MESSAGE YOU WOULD LIKE TO SHOW';
  }, 10, 2 );

(Snippet has not been tested)

This filter is defined in WooCommerce here: https://github.com/woocommerce/woocommerce/blob/e9e382adf8509ae407c68cc5ebef378f29de8cdc/plugins/woocommerce/includes/abstracts/abstract-wc-data.php#L352
