过滤器查询无法通过 Laravel 查询生成器工作

Question

I have a filter query where it checks for three parameters id , keywords and status . It's working totally fine when I run this query in MySQL but when I try to run it through Laravel's query builder it's fetching all the results of that id .

Here is the query which I'm running in MySQL(and it's working fine like I mentioned):

SELECT * FROM `poems`
WHERE book_id = 2
AND p_english_keywords LIKE '%freedom%'
AND p_status = 1

And here is the Laravel's query builder code:

$poems = Poems
     ::where('book_id', '=', $filter, 'AND', 'p_english_keywords', 'LIKE', '%'.$query.'%', 'AND', 'p_status', '=', 1)
     ->orWhere('book_id', '=', $filter, 'AND', 'p_spanish_keywords', 'LIKE', '%'.$query.'%', 'AND', 'p_status', '=', 1)
     ->orWhere('book_id', '=', $filter, 'AND', 'p_german_keywords', 'LIKE', '%'.$query.'%', 'AND', 'p_status', '=', 1)
     ->orWhere('book_id', '=', $filter, 'AND', 'p_urdu_keywords', 'LIKE', '%'.$query.'%', 'AND', 'p_status', '=', 1)
     ->paginate(10);

This query looks totally fine and it's also working fine if a user removes the filter. It's searching for the keywords in user's language. But whenever a user applies a filter, it shows all the results from the filtered book instead of specific keywords in that book. Please Help!

I'm not sure why Poems::where('book_id', '=', $filter, 'AND', 'p_english_keywords', 'LIKE', '%'.$query.'%', 'AND', 'p_status', '=', 1) ever worked for you since that syntax is not in the documentation anywhere so I'm gonna rewrite your query.

$poems = Poems::where(function ($q) use ($filter, $query) {
    $q->where([
        ['book_id', '=', $filter],
        ['p_english_keywords', 'like', '%'.$query.'%'],
        ['p_status', '=', 1],
    ]);
})
->orWhere(function ($q) use ($filter, $query) {
    $q->where([
        ['book_id', '=', $filter],
        ['p_spanish_keywords', 'like', '%'.$query.'%'],
        ['p_status', '=', 1],
    ]);
})
->orWhere(function ($q) use ($filter, $query) {
    $q->where([
        ['book_id', '=', $filter],
        ['p_german_keywords', 'like', '%'.$query.'%'],
        ['p_status', '=', 1],
    ]);
})
->orWhere(function ($q) use ($filter, $query) {
    $q->where([
        ['book_id', '=', $filter],
        ['p_urdu_keywords', 'like', '%'.$query.'%'],
        ['p_status', '=', 1],
    ]);
})
->paginate(10);

However, since you always make the the same filters ( book_id = $filter and p_status = 1 ), I think this can be reduced even further:

$poems = Poems::where([
    ['book_id', '=', $filter],
    ['p_status', '=', 1],
])
->where(function ($q) use ($query) {
    $q->where('p_english_keywords', 'like', '%'.$query.'%')
    ->orWhere('p_spanish_keywords', 'like', '%'.$query.'%')
    ->orWhere('p_german_keywords', 'like', '%'.$query.'%')
    ->orWhere('p_urdu_keywords', 'like', '%'.$query.'%');
})
->paginate(10);

Using toSql() , I get the following query, which I think you're looking for:

select * from `poems`
where (
    `book_id` = ? and `p_status` = ?
)
and (
    `p_english_keywords` like ?
    or `p_spanish_keywords` like ?
    or `p_german_keywords` like ?
    or `p_urdu_keywords` like ?
)
