fastadmin selectpage 下拉编辑默认选中

原因: 因为 selectpage 默认使用的 data-primary-key 为id, 上级默认使用pid

我的字段使用的不是id 和pid

所以导致问题出现(编辑页面不出现默认选中)

fastadmin 官方 selectpage 示例动态下拉(SelectPage) - FastAdmin框架文档 - FastAdmin开发文档

        {:__('Parent_name')}:
        
            
        
    

第一步
重写 data-source 方法
data-source="user/user/indexSelectPage"

 重写indexSelectPage 将搜索指向更改

public function indexSelectPage()
    {
        //设置过滤方法
        $this->request->filter(['strip_tags', 'trim']);
        if ($this->request->isAjax()) {
            //如果发送的来源是Selectpage，则转发到Selectpage
            $keyField = $this->request->request('keyField');
            if ($keyField) {
                return $this->selectpageSelect();
            }
            list($where, $sort, $order, $offset, $limit) = $this->buildparams();
            $list = $this->model
                ->with(['group','invite','level'])
                ->where($where)
                ->order($sort, $order)
                ->paginate($limit);
            foreach ($list as $k => $v) {
                $v->avatar = $v->avatar ? cdnurl($v->avatar, true) : letter_avatar($v->nickname);
                $v->hidden(['password', 'salt']);
            }
            $result = array("total" => $list->total(), "rows" => $list->items());

            return json($result);
        }
        return $this->view->fetch();
    }

第二步
将data-primary-key 限制成你搜索的字段

我的是 inv_code

data-primary-key="inv_code"

第三步
更改selectpageSelect方法  
方法来自  application\common\controller\Backend.php\selectpage
将pid更改成 inv_pcode

只需要修改下面两个地方就可以

 

protected function selectpageSelect()
    {
        //设置过滤方法
        $this->request->filter(['trim', 'strip_tags', 'htmlspecialchars']);

        //搜索关键词,客户端输入以空格分开,这里接收为数组
        $word = (array)$this->request->request("q_word/a");
        //当前页
        $page = $this->request->request("pageNumber");
        //分页大小
        $pagesize = $this->request->request("pageSize");
        //搜索条件
        $andor = $this->request->request("andOr", "and", "strtoupper");
        //排序方式
        $orderby = (array)$this->request->request("orderBy/a");
        //显示的字段
        $field = $this->request->request("showField");
        //主键
        $primarykey = $this->request->request("keyField");
        //主键值
        $primaryvalue = $this->request->request("keyValue");
        //搜索字段
        $searchfield = (array)$this->request->request("searchField/a");
        //自定义搜索条件
        $custom = (array)$this->request->request("custom/a");
        //是否返回树形结构
        $istree = $this->request->request("isTree", 0);
        $ishtml = $this->request->request("isHtml", 0);
        if ($istree) {
            $word = [];
            $pagesize = 999999;
        }
        $order = [];
        foreach ($orderby as $k => $v) {
            $order[$v[0]] = $v[1];
        }
        $field = $field ? $field : 'name';

        //如果有primaryvalue,说明当前是初始化传值
        if ($primaryvalue !== null) {
            $where = [$primarykey => ['in', $primaryvalue]];
            $pagesize = 999999;
        } else {
            $where = function ($query) use ($word, $andor, $field, $searchfield, $custom) {
                $logic = $andor == 'AND' ? '&' : '|';
                $searchfield = is_array($searchfield) ? implode($logic, $searchfield) : $searchfield;
                $searchfield = str_replace(',', $logic, $searchfield);
                $word = array_filter(array_unique($word));
                if (count($word) == 1) {
                    $query->where($searchfield, "like", "%" . reset($word) . "%");
                } else {
                    $query->where(function ($query) use ($word, $searchfield) {
                        foreach ($word as $index => $item) {
                            $query->whereOr(function ($query) use ($item, $searchfield) {
                                $query->where($searchfield, "like", "%{$item}%");
                            });
                        }
                    });
                }
                if ($custom && is_array($custom)) {
                    foreach ($custom as $k => $v) {
                        if (is_array($v) && 2 == count($v)) {
                            $query->where($k, trim($v[0]), $v[1]);
                        } else {

            if ($primaryvalue !== null && preg_match("/^[a-z0-9_\-]+$/i", $primarykey)) {
                $primaryvalue = array_unique(is_array($primaryvalue) ? $primaryvalue : explode(',', $primaryvalue));
                //修复自定义data-primary-key为字符串内容时，给排序字段添加上引号
                $primaryvalue = array_map(function ($value) {
                    return '\'' . $value . '\'';
