在CakePHP中使用FormHelper创建“选择”列表框 [英] Creating 'select' listboxes using FormHelper in CakePHP

问题描述

我有两个模型， Category 和 Point 。关联定义为：

I have two models, Category and Point. The associations are defined as:

Category hasMany Point
Point belongsTo Category

我想在将 Points 添加到我的数据库时，它属于< select> 框，以及表单数据的其余部分。

I would like, when adding Points to my database, to be able to select the category it belongs to from a <select> box, along with the rest of the form data.

我需要设置类别列表，我该如何做呢？

Where would I need to set the category list and how could I do it? And how would I produce the select box?

我假设可以用

$form->input('categorieslist',array('type'=>'select')); //categorieslist needs
                                                        //setting somewhere.

推荐答案

在控制器中：

$categories = $this->Point->Category->find('list');
$this->set(compact('categories'));

在视图中：

$form->input('category_id',array('type'=>'select'));
