cakephp 获取、设置表单值学习笔记
文章给大家提供一篇cakephp 获取、设置表单值学习笔记,希望此文章对大家学习cakephp有所帮助。
cakephp中,不允许直接修改$this->request->data
但是可以用下面的方式设置
//取值 $this->request->data('Post.title'); //设置新值到data中 $this->request->data('Post.title', 'New post!'); /** * Provides a read/write accessor for `$this->data`. Allows you * to use a syntax similar to `CakeSession` for reading post data. * * ## Reading values. * * `$request->data('Post.title');` * * When reading values you will get `null` for keys/values that do not exist. * * ## Writing values * * `$request->data('Post.title', 'New post!');` * * You can write to any value, even paths/keys that do not exist, and the arrays * will be created for you. * * @param string $name,... Dot separated name of the value to read/write * @return mixed Either the value being read, or this so you can chain consecutive writes. */
