Cakephp博客教程 - 编辑例程$ this-> Post-> id = $ id;

Question

In the cakephp blog tutorial in the Edit Post edit() action section

http://book.cakephp.org/2.0/en/tutorials-and-examples/blog/part-two.html

I can't understand what this code does $this->Post->id = $id;

Answer 1

Your url would be something like /posts/edit/1, where $id = 1 in this case. What that line does is set the id for the current record that the Post->save() call will affect.
