In general, the essence is as follows. I have a WP theme, a bulletin board. There you can publish ads, which can then be "highlighted" with color, raised above other ads and other promotion tools. To use these nishtyak, users must pay them. In the subject there are 20 built-in payment methods, but there is not one that would suit me. (All are designed for the market either in India or in England). Question: how to sew there another one, your payment method? I need to embed a button there.
Here is an example code for one of the payment methods. I have no boom boom in php, but if I were told how to remake this code for my needs, I think I could figure it out.
