如何解决针对PHP MySQL的此简单搜索查询

Question

I have a MySQL table (table1) with following fields...

id, title, description, detail, category, status

What I am trying to do is searching these fields with regular php search query... My query for now is...

$q = mysql_query("SELECT * FROM table1 WHERE title LIKE '%$q%' OR description LIKE '%$q%' OR detail LIKE '%$q%' AND category='$cateid' AND status='1' ORDER BY id DESC LIMIT 10");

Where $q is my search string, $cateid is my category id and status is On/Off (Active/Inactive)

Now if get results with this query I got 5 results while I have query string = foo and it only exists in one entry not 5... And also it is showing me the rows with status='0' When I change my query to

$q = mysql_query("SELECT * FROM table1 WHERE title LIKE '%$q%' AND category='$cateid' AND status='1' ORDER BY id DESC LIMIT 10");

It gives me correct results... But I also want to match my query string to description and detail fields respectively. Please help me out.

Answer 1

You need to put parentheses () around all the OR conditions

SELECT * FROM table1
  WHERE (title LIKE '%$q%' OR description LIKE '%$q%' OR detail LIKE '%$q%')
    AND category='$cateid' AND status='1' ORDER BY id DESC LIMIT 10

Answer 2

I think this is the query you need:

$q = mysql_query("SELECT * FROM table1 WHERE
    (title LIKE '%$q%' OR detail LIKE '%$q%')
    AND category='$cateid' AND status='1' ORDER BY id DESC LIMIT 10");
