cakephp 获取、设置表单值学习笔记

作者：袖梨 2022-06-25

cakephp中，不允许直接修改$this->request->data

但是可以用下面的方式设置

代码如下

复制代码

//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.
