After the payment is successful, ecshop Alipay displays "this payment method does not exist or the parameter is incorrect".

The error is as follows: the payment is successful.

 

Cause analysis

This is because the ecshop programmer has an error. The file_exists function cannot properly obtain the correct position of the document when checking the file because no ROOT_PATH is set during file determination.

Solution

In respond. php

If (file_exists ($ plugin_file ))

Change

If (file_exists (ROOT_PATH. $ plugin_file ))

Supplement: The file_exists function is used to determine whether the file exists, while ROOT_PATH is a global variable that is the configuration file of a site directory in ecshop.
