Laravel whereIn 或 whereIn

Question

我正在按过滤器搜索产品：

我的代码：

->where(function($query) use($filter)
{
  if(!empty($filter)){
    foreach ($filter as $key => $value) {           
      $f = explode(",", $value);        
      $query-> whereIn('products.value', $f);
    }           
  }
})

查询：

and (products.value in (Bomann, PHILIPS) and products.value in (red,white)) 

但我需要：

and (products.value in (Bomann, PHILIPS) OR products.value in (red,white)) 

在 Laravel 中是否有类似的东西：

orWhereIn

Answer 1

是的，orWhereIn Laravel 中存在 where 子句方法。有关详细信息，请参阅 Laravel Query Builder 官方文档的以下链接。

文档链接：https://laravel.com/docs/8.x/queries#additional-where-clauses

有两种方法可以得到下面的输出。

and (products.value in (Bomann, PHILIPS) OR products.value in (red,white))

1. 使用orWhereIn

$query = Product::where('color', 'blue')
    ->whereIn('value', ['Bomann', 'PHILIPS'])
    ->orWhereIn('value', ['red', 'white'])
    ->get();

输出：

select * from `products` where `color` = 'blue' and `value` in (Bomann, PHILIPS) OR `value` in (red,white)) 

1. 使用orWhere 和whereIn

$query2 = Product::where('color', 'blue')
    ->whereIn('value', ['Bomann', 'PHILIPS'])
    ->orWhere(function ($query) {
        $query->whereIn('value', ['Bomann', 'PHILIPS']);
    })
    ->get();

输出：

select * from `products` where `color` = 'blue' and `value` in (Bomann, PHILIPS) OR (`value` in (red,white)) 

Answer 2

例如，如果您有多个 whereIn OR whereIn 条件，并且您想放置括号，请这样做：

$getrecord = DiamondMaster::where('is_delete','0')->where('user_id',Auth::user()->id);
if(!empty($request->stone_id))
{
    $postdata = $request->stone_id;
    $certi_id =trim($postdata,",");
    $getrecord = $getrecord->whereIn('id',explode(",", $certi_id))
                           ->orWhereIn('Certi_NO',explode(",", $certi_id));     
}
$getrecord = $getrecord->get();

Answer 3

$query = DB::table('dms_stakeholder_permissions');
$query->select(DB::raw('group_concat(dms_stakeholder_permissions.fid) as fid'),'dms_stakeholder_permissions.rights');
$query->where('dms_stakeholder_permissions.stakeholder_id','4');
$query->orWhere(function($subquery)  use ($stakeholderId){
            $subquery->where('dms_stakeholder_permissions.stakeholder_id',$stakeholderId);
            $subquery->whereIn('dms_stakeholder_permissions.rights',array('1','2','3'));
    });

 $result = $query->get();

return $result;

// 输出@input $stakeholderId = 1

//选择 group_concat(dms_stakeholder_permissions.fid) 作为 fid，dms_stakeholder_permissionss.rights from dms_stakeholder_permissions where dms_stakeholder_permissions.stakeholder_id = 4 或 (dms_stakeholder_permissions.stakeholder_id = 1 和 @987635 @.rights in (1, 2, 3))

Answer 4

是的，orWhereIn 是您可以使用的方法。

我很确定它应该会给你想要的结果，但是，如果没有，你可以简单地使用 implode 创建一个字符串然后分解它（这是对你的数组的猜测结构）：

$values = implode(',', array_map(function($value)
{
    return trim($value, ',');
}, $filters));

$query->whereIn('products.value', explode(',' $values));

Answer 5

你在 Laravel 中有一个 orWhereIn 函数。它采用与whereIn 函数相同的参数。

它不在文档中，但您可以在 laravel API 中找到它。 http://laravel.com/api/4.1/

这应该给你这个：

$query-> orWhereIn('products.value', $f);

Answer 6

您可以只搜索核心中的whereIn 函数来查看。给你。这必须回答你所有的问题

/**
 * Add a "where in" clause to the query.
 *
 * @param  string  $column
 * @param  mixed   $values
 * @param  string  $boolean
 * @param  bool    $not
 * @return \Illuminate\Database\Query\Builder|static
 */
public function whereIn($column, $values, $boolean = 'and', $not = false)
{
    $type = $not ? 'NotIn' : 'In';

    // If the value of the where in clause is actually a Closure, we will assume that
    // the developer is using a full sub-select for this "in" statement, and will
    // execute those Closures, then we can re-construct the entire sub-selects.
    if ($values instanceof Closure)
    {
        return $this->whereInSub($column, $values, $boolean, $not);
    }

    $this->wheres[] = compact('type', 'column', 'values', 'boolean');

    $this->bindings = array_merge($this->bindings, $values);

    return $this;
}

看看它有第三个布尔参数。祝你好运。
