要實(shí)現(xiàn)下圖效果
?一、先創(chuàng)建數(shù)據(jù)表
二、在目標(biāo)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()
{
//設(shè)置過濾方法
$this->request->filter(['strip_tags']);
if ($this->request->isAjax()) {
//構(gòu)造父類select列表選項(xiàng)數(shù)據(jù)
$list = $this->categorylist;;
$total = count($list);
$result = array("total" => $total, "rows" => $list);
return json($result);
}
return $this->view->fetch();
}
/**
* 編輯
*/
public function edit($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);
$result = false;
Db::startTrans();
try {
//是否采用模型驗(yàn)證
if ($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 $this->view->fetch();
}
修改和添加下面兩個(gè)方法
三、
1、在目標(biāo)js中，添加代碼，去掉首頁html字符
2、 表格字段居左，這樣是為了看效果更加明顯
{field: 'name', title: __('Name'), operate: 'LIKE', align:'left'},
四，在目標(biāo)view中修改add.html和edit.html的pid代碼
add.html
<div class="form-group">
<label class="control-label col-xs-12 col-sm-2">{:__('Pid')}:</label>
<div class="col-xs-12 col-sm-8">
<select id="c-pid" data-rule="required" class="form-control selectpicker" name="row[pid]">
{foreach name="parentList" item="vo"}
<option value="{$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>
完成上面步驟后，下拉分類就已完成，但在添加分類商品時(shí)，在編輯時(shí)會出現(xiàn)selepage未選中狀態(tài)，還要進(jìn)行修改
一、分類商品中用了zxdc_categorys_id字段來做分類ID，在add添加時(shí)一切正常，在edit時(shí)要進(jìn)行修改，在分類商品的controall中重寫edit方法，把分類數(shù)值獲取下發(fā)文章來源：http://www.zghlxwxcb.cn/news/detail-653330.html
/**
* 編輯
*/
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);
$result = false;
Db::startTrans();
try {
//是否采用模型驗(yàn)證
if ($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 $this->view->fetch();
}
二、在對應(yīng)的view的edit.html中，修改文章來源地址http://www.zghlxwxcb.cn/news/detail-653330.html
<div class="form-group">
<label class="control-label col-xs-12 col-sm-2">{:__('Zxdc_categorys_id')}:</label>
<div class="col-xs-12 col-sm-8">
<select id="c-zxdc_categorys_id" data-rule="required" class="form-control selectpicker" name="row[zxdc_categorys_id]">
{foreach name="parentList" item="vo"}
<option value="{$key}" {in name="key" value="$row.zxdc_categorys_id"}selected{/in}>{$vo.name}</option>
{/foreach}
</select>
</div>
</div>
