聯接到數據透視表Mysql

Question

我正在用多個輸入進行搜索並查詢數據庫，我的表單很簡單，這就是我的POST的結構

[search-word] => casas
[status] => sale,rent
[type] => condo,house,commercial,lot,fractional,business,boat,villa
[beds] => 2
[baths] => 3
[amenities] => handicap facilities,children allowed,security,furnished,pet friendly,jacuzzy

在我以這種方式獲得並進行查詢之后

$query = "SELECT pr.* FROM properties as pr 
  INNER JOIN status as st
    ON pr.status_id = st.id
  INNER JOIN types as ty
    ON pr.type_id = ty.id
  INNER JOIN property_has_features as prfe
    ON prfe.property_id = pr.id
  INNER JOIN features as fe
    ON prfe.feature_id = fe.id
  WHERE ";

狀態和類型在具有status_id和type_id的屬性表中具有外鍵，但是便利設施是數據透視表properties_has_features我試圖通過最后兩個聯接來獲取

INNER JOIN property_has_features as prfe
ON prfe.property_id = pr.id
INNER JOIN features as fe
ON prfe.feature_id = fe.id

但這不起作用，畢竟我獲取了數組以獲取值

$status = explode(",", $status);
$type = explode(",", $type);
$amenities = explode(",", $amenities);
$statusCount = 0;
$typeCount = 0;
$amenitiesCount = 0;

foreach ($status as $v) {
  if ($statusCount > 0){
    $query .= "OR ";
  }
  $query .= "st.title = '$v' "; 
  ++$statusCount;
}

foreach ($type as $k) {
  if ($typeCount > 0){
    $query .= "OR ";
  }else{
    $query .= "AND ";
  }
  $query .= "ty.title = '$k' "; 
  ++$typeCount;
}

foreach ($amenities as $j) {
  if ($amenitiesCount > 0){
    $query .= "OR ";
  }else{
    $query .= "AND ";
  }
  $query .= "fe.title = '$j' "; 
  ++$amenitiesCount;
}

$query .= "
  AND pr.beds LIKE '%".$beds."' 
  AND pr.baths LIKE '%".$baths."'
";

惠特這我獲得了所有屬性，但未篩選便利設施，如果我刪除查詢的便利設施，此類型和狀態都很好，我一直在尋找並查看一些有關Group_concat（）的信息以及其他信息，但是我想建議我的問題， 謝謝

UPDATE

這是我從該咨詢中得到的實際查詢

SELECT pr.* FROM properties as pr 
  INNER JOIN status as st
    ON pr.status_id = st.id
  INNER JOIN types as ty
    ON pr.type_id = ty.id
  INNER JOIN property_has_features as prfe
    ON prfe.property_id = pr.id
  INNER JOIN features as fe
    ON prfe.feature_id = fe.id
  WHERE st.title = 'sale' OR st.title = 'rent' AND ty.title = 'condo' OR ty.title = 'house' OR ty.title = 'commercial' OR ty.title = 'lot' OR ty.title = 'fractional' OR ty.title = 'business' OR ty.title = 'boat' OR ty.title = 'villa' AND fe.title = 'handicap facilities' OR fe.title = 'children allowed' OR fe.title = 'security' OR fe.title = 'furnished' OR fe.title = 'pet friendly' OR fe.title = 'jacuzzy' 
AND pr.beds LIKE '%' 
AND pr.baths LIKE '%'

這是數據透視表的properties_has_features

id | property_id | featured_id

功能表具有

id | title

// I'm largely leaving your code as-is, but you could replace the
// list of ORs with an IN()
// The main change is that you need to enclose each attribute group
// within parenthesis so that the logical AND/OR processing is correct
if(is_array($status) && !empty($status))
{
    foreach ($status as $v) {
        if ($statusCount > 0){
            $query .= "OR ";
        }
        else{
            $query .= "(";
