要实现下图效果
一、先创建数据表
二、在目标的controll中引入use fast\Tree;
public function _initialize()
{
parent::_initialize();
$this->model = new \app\admin\model\zxdc\Categorys;
$tree = Tree::instance();
$tree->init(collection($this->model->order('id desc')->select())->toArray(), 'pid');
$this->categorylist = $tree->getTreeList($tree->getTreeArray(0), 'name');
$categorydata = [0 => ['id' => '0', 'name' => __('None')]];
foreach ($this->categorylist as $k => $v) {
$categorydata[$v['id']] = $v;
}
$this->view->assign("parentList", $categorydata);
}
public function index()
{
//设置过滤方法
$this->request->filter(['strip_tags']);
if ($this->request->isAjax()) {
//构造父类select列表选项数据
$list = $this->categorylist;;
$total = count($list);
$result = array("total" => $total, "rows" => $list);
return json($result);
}
return $this->view->fetch();
}
/**
* 编辑
*/
public function edit($ids = null)
{
$row = $this->model->get($ids);
if (!$row) {
$this->error(__('No Results were found'));
}
$adminIds = $this->getDataLimitAdminIds();
if (is_array($adminIds)) {
if (!in_array($row[$this->dataLimitField], $adminIds)) {
$this->error(__('You have no permission'));
}
}
if ($this->request->isPost()) {
$params = $this->request->post("row/a");
if ($params) {
if ($params['pid'] == $row['id']) {
$this->error(__('Can not change the parent to self'));
}
$params = $this->preExcludeFields($params);
$result = false;
Db::startTrans();
try {
//是否采用模型验证
if ($this->modelValidate) {
$name = str_replace("\\model\\", "\\validate\\", get_class($this->model));
$validate = is_bool($this->modelValidate) ? ($this->modelSceneValidate ? $name . '.edit' : $name) : $this->modelValidate;
$row->validateFailException(true)->validate($validate);
}
$result = $row->allowField(true)->save($params);
Db::commit();
} catch (ValidateException $e) {
Db::rollback();
$this->error($e->getMessage());
} catch (PDOException $e) {
Db::rollback();
$this->error($e->getMessage());
} catch (Exception $e) {
Db::rollback();
$this->error($e->getMessage());
}
if ($result !== false) {
$this->success();
} else {
$this->error(__('No rows were updated'));
}
}
$this->error(__('Parameter %s can not be empty', ''));
}
$this->view->assign("row", $row);
return $this->view->fetch();
}
修改和添加下面两个方法
三、
1、在目标js中，添加代码，去掉首页html字符
2、 表格字段居左，这样是为了看效果更加明显
{field: 'name', title: __('Name'), operate: 'LIKE', align:'left'},
四，在目标view中修改add.html和edit.html的pid代码
add.html
<div class="form-group">
<label class="control-label col-xs-12 col-sm-2">{:__('Pid')}:</label>
<div class="col-xs-12 col-sm-8">
<select id="c-pid" data-rule="required" class="form-control selectpicker" name="row[pid]">
{foreach name="parentList" item="vo"}
<option value="{$key}" {in name="key" value=""}selected{/in}>{$vo.name}</option>
{/foreach}
</select>
</div>
</div>
edit.html
<div class="form-group">
<label class="control-label col-xs-12 col-sm-2">{:__('Pid')}:</label>
<div class="col-xs-12 col-sm-8">
<select id="c-pid" data-rule="required" class="form-control selectpicker" name="row[pid]">
{foreach name="parentList" item="vo"}
<option value="{$key}" {in name="key" value="$row.pid"}selected{/in}>{$vo.name}</option>
{/foreach}
</select>
</div>
</div>
完成上面步骤后，下拉分类就已完成，但在添加分类商品时，在编辑时会出现selepage未选中状态，还要进行修改
一、分类商品中用了zxdc_categorys_id字段来做分类ID，在add添加时一切正常，在edit时要进行修改，在分类商品的controall中重写edit方法，把分类数值获取下发
/**
* 编辑
*/
public function edit($ids = null)
{
$test = new \app\admin\model\zxdc\Categorys;
$tree = Tree::instance();
$tree->init(collection($test->order('id desc')->select())->toArray(), 'pid');
$this->categorylist = $tree->getTreeList($tree->getTreeArray(0), 'name');
$categorydata = [0 => ['id' => '0', 'name' => __('None')]];
foreach ($this->categorylist as $k => $v) {
$categorydata[$v['id']] = $v;
}
$this->view->assign("parentList", $categorydata);
$row = $this->model->get($ids);
if (!$row) {
$this->error(__('No Results were found'));
}
$adminIds = $this->getDataLimitAdminIds();
if (is_array($adminIds)) {
if (!in_array($row[$this->dataLimitField], $adminIds)) {
$this->error(__('You have no permission'));
}
}
if ($this->request->isPost()) {
$params = $this->request->post("row/a");
if ($params) {
$params = $this->preExcludeFields($params);
$result = false;
Db::startTrans();
try {
//是否采用模型验证
if ($this->modelValidate) {
$name = str_replace("\\model\\", "\\validate\\", get_class($this->model));
$validate = is_bool($this->modelValidate) ? ($this->modelSceneValidate ? $name . '.edit' : $name) : $this->modelValidate;
$row->validateFailException(true)->validate($validate);
}
$result = $row->allowField(true)->save($params);
Db::commit();
} catch (ValidateException $e) {
Db::rollback();
$this->error($e->getMessage());
} catch (PDOException $e) {
Db::rollback();
$this->error($e->getMessage());
} catch (Exception $e) {
Db::rollback();
$this->error($e->getMessage());
}
if ($result !== false) {
$this->success();
} else {
$this->error(__('No rows were updated'));
}
}
$this->error(__('Parameter %s can not be empty', ''));
}
$this->view->assign("row", $row);
return $this->view->fetch();
}
二、在对应的view的edit.html中，修改
<div class="form-group">
<label class="control-label col-xs-12 col-sm-2">{:__('Zxdc_categorys_id')}:</label>
<div class="col-xs-12 col-sm-8">
<select id="c-zxdc_categorys_id" data-rule="required" class="form-control selectpicker" name="row[zxdc_categorys_id]">
{foreach name="parentList" item="vo"}
<option value="{$key}" {in name="key" value="$row.zxdc_categorys_id"}selected{/in}>{$vo.name}</option>
{/foreach}
</select>
</div>
</div>
