내 페이팔 기부 웹 페이지에서이 오류가 발생하며이를 중지하는 방법을 잘 모릅니다.경고 : mysql_num_rows() : 제공된 인수가 유효한 MySQL 결과 리소스가 아닙니다. - 페이팔 기부 스크립트
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/sixthr6/public_html/donation/donate.php on line 116
나는이 문제를 해결할 수있는 방법을 찾을 때까지 지금은 데모 모드입니다. 필자는 데모 모드에서 가짜 기부를 할 때 주 페이지에 주석을 저장하지 않고 그 오류를 던지기 때문에 왜 올바른 테이블을 사용하여 사용자 정의 mySQL 데이터베이스를 설정했는지 알 수 없습니다. 여기
질문 나는이 웹 사이트 http://tutorialzine.com/2010/05/donation-center-php-mysql-paypal-api/에서 코딩을 사용하고<?php

<h3>Hello, dear visitor!</h3>
<p>This is Tutorialzine's Donation Center. It utilizes PayPal's APIs to bring you a fully fledged donation solution. It is currently in <strong>Demo Mode</strong>, which means that PayPal is bypassed and you can donate as much as you want to test the functionality. You can, however, just change a variable in the config.php file to enable real donations.</p>
