Fastadmin 自定義Tab選項卡（B表的條件查詢A表的資料，在A表裡面加B表的引數作為選項卡）

上圖：
個人、推廣員、商業使用者都是在使用者表裡面的一個type欄位，當前訂單表通過user_id關聯了使用者表。
第一步：
在_initialize方法裡面加上 $this->view->assign("newList", $this->model->getNewList());
getNewList 方法如下，其實就是自定義的
public function getNewList(){
return ['person' => __('個人'), 'genera' => __( 然後再對應的Html下面加上這個
<div class="panel-heading">
{:build_heading(null,FALSE)}
<ul class="nav nav-tabs" data-field="user_id">
<li class="active"><a href="#t-all" data-value=" 第二步
在對應的js裡面的index方法裡面加上這個：
// 繫結TAB事件
$('.panel-heading a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
var field = $(this).closest("ul").data("field");
var value = $(this).data("value");
var options = table.bootstrapTable('getOptions');
options.pageNumber = 1;
options.queryParams = function (params) {
var filter = {};
if (value !== '') {
filter[field] = value;
}
params.filter = JSON.stringify(filter);
return params;
};
table.bootstrapTable('refresh', {});
return false;
});
// 為表格繫結事件
Table.api.bindevent(table);
第三步就是接收資料處理資料了
buildparams方法主要是過濾掉了 filter欄位，改為：$filter = '{}';,不去接收get引數
$c=null;
$t=$this->request->param();
if(isset($t['filter'])){
if($t['filter']!='{}'){
$c=$t['filter'];
}
}
上面這段程式碼主要是為了提前接收到傳值 filter,並且做好儲存，加上$where2查詢條件作為新條件的處理。
$where2=array();
if($c){
$type=(array)json_decode($c,true)['user_id'];
$user=new \app\admin\model\User();
$ids=$user->where(['type'=>$type[0]])->column('id');
$where2=['user_id'=>['in',$ids]];
}
上面這段程式碼核心思想 where in ，想必到這裡基本上就能解決問題了，程式碼再騷，問題解決才是關鍵。
下面貼出來完整的index方法跟buildparams兩個方法，講解在上面：
/**
* 檢視
*/
public function index()
{
// $this->relationSearch=true;
//設定過濾方法
$this->request->filter(['strip_tags']);
if ($this->request->isAjax()) {
//如果傳送的來源是Selectpage，則轉發到Selectpage
$c=null;
$t=$this->request->param();
if(isset($t['filter'])){
if($t['filter']!='{}'){
$c=$t['filter'];
}
}
if ($this->request->request('keyField')) {
return $this->selectpage();
}
list($where, $sort, $order, $offset, $limit) = $this->buildparams();
$where2=array();
if($c){
$type=(array)json_decode($c,true)['user_id'];
$user=new \app\admin\model\User();
$ids=$user->where(['type'=>$type[0]])->column('id');
$where2=['user_id'=>['in',$ids]];
}
$total = $this->model
->with(['user','maindata'])
->where($where)
->where($where2)
->order($sort, $order)
->count();
$list = $this->model
->with(['user','maindata'])
->where($where)
->where($where2)
->order($sort, $order)
->limit($offset, $limit)
->select();
$list = collection($list)->toArray();
$result = array("total" => $total, "rows" => $list);
return json($result);
}
return $this->view->fetch();
}
