Question

我正在使用多个输入进行搜索并咨询数据库，我的表单很简单，这是我的POST的结构

[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

在我以这种方式获得并提出查询之后

$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 ";

状态和类型在属性表中有一个外键，其中包含status_id和type_id，但是设施是一个数据透视表properties_has_features我试图通过最后两个连接获取

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

但这不起作用，毕竟我获取数组以获取值

$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."'
";

惠特这个我得到所有的属性，但没有过滤的设施，如果我删除查询的设施这项工作正常的类型和状态，我正在寻找和查看一些关于Group_concat（）和其他的东西，但我想建议关于我的问题，谢谢

更新

这是我从该咨询中获得的实际查询

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 '%'

id | property_id | featured_id

功能表有

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){
