使用Yii2-dynamicforms更新(嵌套动态表单)

[英]Update with Yii2-dynamicforms (Nested dynamic forms)

In my Yii 2 project, I have a Nested dynamic form working with yii2-dynamicform extension. 在我的Yii 2项目中,我有一个使用yii2-dynamicform扩展的嵌套动态表单。 I could make it work following the wiki guide , but I had to ask for help in this StackOverflow question to make it work properly. 我可以按照wiki指南进行操作 ,但我不得不在StackOverflow问题中寻求帮助以使其正常工作。 But I'm having a little problem on Update, when I try to add more fields. 但是当我尝试添加更多字段时,我在Update上遇到了一些问题。

Before explain, let me show my scenario: 在解释之前,让我展示一下我的场景: 在此输入图像描述

在此输入图像描述

My problem: 我的问题:

Updating a record, when I click to Add a new Slot field, instead of adding just one, it adds the number of groups that I have already added. 更新记录时,当我单击添加新的插槽字段而不是仅添加一个时,它会添加我已添加的组的数量。

For example: In the image above I have two groups (group1 and group2). 例如:在上图中,我有两个组(group1和group2)。 If i click to add one slot, it adds two (number of groups) slots at once. 如果我单击添加一个插槽,它会一次添加两个(组的数量)插槽。

Anyone can help me, please? 有人可以帮帮我吗?
