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)
解决
完整代码
{:__('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 {
$query->where($k, '=', $v);
}
}
}
};
}
$adminIds = $this->getDataLimitAdminIds();
if (is_array($adminIds)) {
$this->model->where($this->dataLimitField, 'in', $adminIds);
}
$list = [];
$total = $this->model->where($where)->count();
if ($total > 0) {
if (is_array($adminIds)) {
$this->model->where($this->dataLimitField, 'in', $adminIds);
}
$fields = is_array($this->selectpageFields) ? $this->selectpageFields : ($this->selectpageFields && $this->selectpageFields != '*' ? explode(',', $this->selectpageFields) : []);
//如果有primaryvalue,说明当前是初始化传值,按照选择顺序排序
if ($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 . '\'';
}, $primaryvalue);
$primaryvalue = implode(',', $primaryvalue);
$this->model->orderRaw("FIELD(`{$primarykey}`, {$primaryvalue})");
} else {
$this->model->order($order);
}
$datalist = $this->model->where($where)
->page($page, $pagesize)
->select();
foreach ($datalist as $index => $item) {
unset($item['password'], $item['salt']);
if ($this->selectpageFields == '*') {
$result = [
$primarykey => isset($item[$primarykey]) ? $item[$primarykey] : '',
$field => isset($item[$field]) ? $item[$field] : '',
];
} else {
$result = array_intersect_key(($item instanceof Model ? $item->toArray() : (array)$item), array_flip($fields));
}
$result['inv_pcode'] = isset($item['inv_pcode']) ? $item['inv_pcode'] : (isset($item['parent_id']) ? $item['parent_id'] : 0);
$list[] = $result;
}
if ($istree && !$primaryvalue) {
$tree = Tree::instance();
$tree->init(collection($list)->toArray(), 'inv_pcode');
$list = $tree->getTreeList($tree->getTreeArray(0), $field);
if (!$ishtml) {
foreach ($list as &$item) {
$item = str_replace(';', ' ', $item);
}
unset($item);
}
}
}
//这里一定要返回有list这个字段,total是可选的,如果total $list, 'total' => $total]);
}
最终效果
