【中文标题】如何从同一类中的另一个方法检索最后插入的 id？【英文标题】：How to retrieve the last inserted id from another method inside same class? 【发布时间】：2019-10-24 23:11:22 【问题描述】：我在Home 类中有两个方法，分别称为addProperty 和uploadImages。
我从 jquery dropzone 调用 uploadImages() 方法来发布图像，并调用 addProperty() 将表单输入插入数据库。
我想将最后插入的 Id 从 addProperty 方法传递给 uploadImages 以将图像详细信息保存到数据库中。

我想将图像详细信息插入到名为 tbl_property_images 的表中
-
文件上传工作
表单输入也成功插入
问题：
我需要使用propertyid 将图像详细信息插入到表中，propertyid 是我们从addProperty 方法中的$result 变量中获得的最后插入的id。
【问题讨论】：
出于好奇。需要exit('No direct script access allowed');的部分吗？
不需要那个？？
我不知道。这就是我问的原因
我不太了解你的代码，但是如果你需要在 add 属性中保存一个 Id，只需将其设置为“home”类的属性，这样你就可以使用它了来自同一类中的 uploadimage 方法。
尝试改进格式，以便于阅读。
【参考方案1】：
解决方案 1 创建一个插入记录并返回插入记录的 id 的过程。
解决方案 2 创建一个将所有数据插入各个表并返回成功或失败的过程。
【讨论】：
以上是关于如何从同一类中的另一个方法检索最后插入的 id？的主要内容，如果未能解决你的问题，请参考以下文章
