php - 循环重复相同的数据 8 次或更多次

Question

我正在使用 foreach 循环在表上显示数据，但不知道是什么导致相同的数据在循环中重复 8 次或更多次。

例如，id = 1 的列重复 8 次，那么 id = 2 的列将显示 8 次，依此类推。我已经尝试了很多，但似乎我最后给出的连接查询有一些问题

Blade.php

                        <thead>

                        @endforeach

                    </table>

这是我用于循环名称“join”的查询

$join = DB::table('leaves_policy')
    ->join('leaves_policies', 'leaves_policy.leave_policy', '=', 'leaves_policies.title')
    ->join('leaves_requests', 'leaves_policy.requested_by' , '=', 'leaves_requests.requested_by')
    ->select('leaves_policy.*', 'leaves_policies.title', 'leaves_policies.total_no_of_leaves_allowed_per_year',
        'leaves_policies.no_of_months_leaves_valid', 'leaves_policies.max_leaves_per_month', 'leaves_policies.max_con_leaves_per_month',
        'leaves_requests.leave_status')
    ->get();

Answer 1

尝试使用分组依据进行此查询

$join = DB::table('leaves_policy')
    ->join('leaves_policies', 'leaves_policy.leave_policy', '=', 'leaves_policies.title')
    ->join('leaves_requests', 'leaves_policy.requested_by' , '=', 'leaves_requests.requested_by')
    ->select('leaves_policy.*', 'leaves_policies.title', 'leaves_policies.total_no_of_leaves_allowed_per_year',
        'leaves_policies.no_of_months_leaves_valid', 'leaves_policies.max_leaves_per_month', 'leaves_policies.max_con_leaves_per_month',
        'leaves_requests.leave_status')
    ->groupBy('leaves_policy.id')    
    ->get();
