Cakephp 中的 getLastInsertId() 等价于什么? [英] What is the equivalent to getLastInsertId() in Cakephp?

问题描述

如果我在 save() 之后立即执行 getLastInsertId()，它会起作用，否则就不起作用.这在我的控制器中得到了证明:

If I do getLastInsertId() immediately after a save(), it works, but otherwise it does not. This is demonstrated in my controller:

function designpage() {
    //to create a form Untitled
    $this->Form->saveField('name','Untitled Form');
    echo $this->Form->getLastInsertId(); //here it works
}

function insertformname() {
    echo $this->Form->getLastInsertId(); //this doesnt echo at all
}

请提出获得我想要的功能的方法.

Please suggest a way to get the functionality I want.

推荐答案

CakePHP 有两种获取最后插入 id 的方法:Model::getLastInsertID() 和 Model::getInsertID().实际上这些方法是相同的，所以你使用哪种方法并不重要.

CakePHP has two methods for getting the last inserted id: Model::getLastInsertID() and Model::getInsertID(). Actually these methods are identical so it really doesn't matter which method you use.

echo $this->ModelName->getInsertID();
echo $this->ModelName->getLastInsertID();

这些方法可以在 cake/libs/model/model.php 第 2768 行找到

This methods can be found in cake/libs/model/model.php on line 2768
