如何在WHERE子句上使用多个OR？

Question

I am having a problem with my MYSQL statement

Warning : mysqli_num_rows() expects parameter 1 to be mysqli_result, bool given in C:\Users\R.B.Lara\Documents\My Projects\focalnews\index.php on line 188

$sqltype = "SELECT * FROM focalnews_items ORDER BY datime ASC limit $last,20 WHERE (likes >= 5 OR love >= 5 OR informative >= 5)";

$resulttype = mysqli_query($conn, $sqltype);

if (mysqli_num_rows($resulttype) > 0) {
    while($row = mysqli_fetch_assoc($resulttype))
    {
        $profile_pic = $row["profile_pic"];
        $author = $row["author"];
        $message = $row["message"];
        $likes = $row["likes"];
        $love = $row["love"];
        $informative = $row["informative"];
        $datime = $row["datime"];
        $joined_date = $row["joined_date"];
    }
}
?>

Any Idea please?

ORDER BY and LIMIT should be goes at the end.

You can use the multiple conditions in OR as follows

WHERE  likes >= 5 OR love >= 5 OR informative >= 5

Your query should be

$sqltype = "SELECT * FROM focalnews_items WHERE likes >= 5 OR love >= 5 OR informative >= 5 ORDER BY datime ASC limit $last,20";
