邮件发送脚本

Question

///Send mail to members whom subscribed to receive mail

$one = 1;
settype($one, 'integer');

$two = 2;
settype($two, 'integer');

$query_news_mail = "SELECT M.id, M.j_email, M.j_news_alert, M.j_news_catid_notification FROM jt_members M WHERE (M.j_news_alert = $two AND M.j_news_catid_notification = $data[catid]) AND M.j_news_alert = $one;";
$mail_result = mysql_query($query_news_mail) or die(trigger_error(MYSQL_ERROR_MSG,E_USER_ERROR));

while($row_mail = mysql_fetch_assoc($mail_result)) {


//start sending mails here
echo "mail";
}

第二个子句不执行//M.j_news_alert = $ one 任何想法？ 感谢

Answer 1

也许你的意思

... notice the OR in place of AND ...
(M.j_news_alert = $two AND M.j_news_catid_notification = $data[catid]) OR M.j_news_alert = $one;

否则您无法满足您的WHERE条件：M.j_news_alert = $two AND M.j_news_alert = $one;

Answer 2

(M.j_news_alert = $two AND M.j_news_catid_notification = $data[catid])
AND M.j_news_alert = $one;

这永远不会是true，所以最终会得到一个空的结果集。

Answer 3

SELECT M.id，M.j_email，M.j_news_alert，M.j_news_catid_notification 来自jt_members M. WHERE（M.j_news_alert = $ two AND M.j_news_catid_notification = $ data [catid]）或M.j_news_alert = $ one;“

是的，我认为你需要并且意味着OR

编辑：看起来有人打败了我。
