Get and post in cakephp
提问by OhDude
In Codeigniter I do this
在 Codeigniter 我这样做
$p=$this->input->post();
to get all objects posted but I don't know if there is something similar in cakephp to get all posted variables from a form ? I am writing a function to get posted password and save it into database in place of the old password recorded there.
获取发布的所有对象，但我不知道 cakephp 中是否有类似的东西可以从表单中获取所有发布的变量？我正在编写一个函数来获取发布的密码并将其保存到数据库中以代替记录在那里的旧密码。
I use native php to get 'posted' variables from a form, (I am not familiar with cakephp form usage) that is why, so instead of using $_POST['sssss'] what should I do now ?
我使用本机 php 从表单中获取“发布”变量，（我不熟悉 cakephp 表单的用法）这就是为什么，所以我现在应该做什么而不是使用 $_POST['sssss'] ？
Thank you for any help.
感谢您的任何帮助。

$value = $this->request->data('key');
Please for further reference, read the manual. It's so much easier and better for yourself to figure it out by yourself.
如需进一步参考，请阅读手册。对自己来说，自己弄清楚要容易得多，也更好。

The Post data must be in data to show up in $this->request->data.
Post 数据必须在 data 中才能显示在 $this->request->data 中。
Example:
例子：
// input field
<input type="text" name="data[foo]" value="bar" />
// in your controller
debug($this->request->data);

If you want to get a specific field of the table can move so:
如果要获取表的特定字段可以这样移动：
if($this->data["Objetorastreavel"]["id"]){
}
It checks only the ID Objetorestraevalif you want to pick only one field and not post the whole page.
Objetorestraeval如果您只想选择一个字段而不是发布整个页面，它只会检查 ID 。
