Php 我的MySQL查询无法工作

我在以下查询中搜索了一个插曲指南数据库，以查找用户输入的数据：

$query = "SELECT * 
            FROM epguide 
           WHERE EpisodeTitle LIKE '%$trimmed%' 
              OR Synopsis LIKE '%$trimmed%' 
              OR Notes LIKE '%$trimmed%' 
        ORDER BY o";

这工作正常，但当我添加“Series=”$ser”和“it stop:

$query = "SELECT * 
            FROM epguide 
           WHERE Series = '$ser' 
             AND EpisodeTitle LIKE '%$trimmed%' 
              OR Synopsis LIKE '%$trimmed%' 
              OR Notes LIKE '%$trimmed%' 
        ORDER BY o";

---

看起来应该能用。我能做些什么来修复它？

您需要决定您的意思是

SELECT * FROM epguide WHERE (Series = '$ser' AND EpisodeTitle LIKE '%$trimmed%') OR Synopsis LIKE '%$trimmed%' OR Notes LIKE '%$trimmed%' ORDER BY o

或

---

并适当地修改查询。

您需要决定是否

SELECT * FROM epguide WHERE (Series = '$ser' AND EpisodeTitle LIKE '%$trimmed%') OR Synopsis LIKE '%$trimmed%' OR Notes LIKE '%$trimmed%' ORDER BY o

或

并适当修改查询。

使用：

  SELECT * 
    FROM epguide 
   WHERE Series = '$ser' 
     AND (EpisodeTitle LIKE '%$trimmed%' 
          OR Synopsis LIKE '%$trimmed%' 
          OR Notes LIKE '%$trimmed%')
ORDER BY o

您需要括号来分隔WHERE子句中的语句。

使用：

  SELECT * 
    FROM epguide 
   WHERE Series = '$ser' 
     AND (EpisodeTitle LIKE '%$trimmed%' 
          OR Synopsis LIKE '%$trimmed%' 
          OR Notes LIKE '%$trimmed%')
ORDER BY o

在WHERE子句中，需要用括号分隔/分组语句
