我用了TP5关联表新增，其他数据能得到都行,就是mytext提示未定义数组
模型：
$data=[
'store_id' => 0,
'cate_id' => $data['cateid'],
'attr_name' => $data['attrname'],
];
if($this->attribute->save())
{

$d['attr_value_name'] = $data['mytext'];
dump($d['attr_value_name']);exit;
return $this->attribute->attrs()->save($d);
}
控制器：
public function save()
{
$data = input('param.');
$data['mytext'] = input('param.mytext/a');

$attr = new Attribute();
$result = $attr->addAttr($data);
}
前台:
<div class="layui-input-inline">
<input type="text" id="field_1" name="mytext[]" required=""
autocomplete="off" class="layui-input" value="" style="margin-bottom:15px;">
</div>
