Php 查询未正确筛选结果

这是我的疑问：

$sql = "SELECT * , (3956 * 2 * ASIN(SQRT( POWER(SIN(('$lat' - lat) *  pi()/180 / 2), 2) +COS('$lat' * pi()/180) * COS(lat * pi()/180) * POWER(SIN(('$lon' - lon) * pi()/180 / 2), 2) ))) as distance  from posts WHERE posts.subname LIKE '%$subject%' AND posts.pricing <= '$rate' ".$add_here." GROUP BY posts.UUID having  distance <= '$distance' order by distance";

在浏览器中

SELECT * , 
(3956 * 2 * ASIN(SQRT( POWER(SIN(('2.993518' - lat) * pi()/180 / 2), 2) + 
COS('2.993518' * pi()/180) * COS(lat * pi()/180)
 * POWER(SIN(('101.7874058' - lon) * pi()/180 / 2), 2) ))) 
    as distance
from posts 
WHERE posts.subname LIKE '%tamil%' 
AND posts.pricing <= '161' 
AND posts.morning IN ('sun') 
OR posts.afternoon IN ('sun') OR posts.evening IN ('sun','mon') 
GROUP BY posts.UUID 
having distance <= '40' 
order by distance

我遇到的问题是，此查询的结果不会筛选子名称。它只是过滤和帖子。定价问题在于你的WHERE子句

WHERE posts.subname LIKE '%tamil%' 
AND posts.pricing <= '161' 
AND posts.morning IN ('sun') 
OR posts.afternoon IN ('sun') OR posts.evening IN ('sun','mon') 

如果我理解你的意思，你是想说选择： “%tamil%”和定价

WHERE posts.subname LIKE '%tamil%' 
AND posts.pricing <= '161' 
AND (posts.morning IN ('sun') 
    OR posts.afternoon IN ('sun') 
    OR posts.evening IN ('sun','mon'))
