我想扩展cakephp 3。X博客教程。
我想有添加文章表单(文章/添加)让您选择一个类别或创建一个新的类别，并将其链接到新的文章。
如果在articles/add.ctp:
<h1>Add Article</h1>
<?php
echo $this->Form->create($article);
echo $this->Form->input('title');
echo $this->Form->input('category_id');
echo $this->Form->input('name');
echo $this->Form->input('body', ['rows' => '3']);
echo $this->Form->button(__('Save Article'));
echo $this->Form->end();
?>
在articlescontroller。php中添加
public function add()
{
$article = $this->Articles->newEntity();
if ($this->request->is('post')) {
if($this->request->data['category_id']==""){
$this->Categories->add($category );
}
$article = $this->Articles->patchEntity($article, $this->request->data);
// Added this line
$article->user_id = $this->Auth->user('id');
// You could also do the following
//$newData = ['user_id' => $this->Auth->user('id')];
//$article = $this->Articles->patchEntity($article, $newData);
if ($this->Articles->save($article)) {
$this->Flash->success(__('Your article has been saved.'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('Unable to add your article.'));
}
$this->set('article', $article);
$categories = $this->Articles->Categories->find('treeList');
$this->set(compact('categories'));
// Just added the categories list to be able to choose
// one category for an article
// $categories = $this->Articles->Categories->find('treeList');
//$this->set(compact('categories'));
}
但我得到一个"未知的方法"错误上类别->添加
如何同时添加类别?
这意味着在表Categories中没有方法。你必须像这样在src/Model/Table/categoriable .php中创建方法:
public function add($data)
{
$category = new Entity();
$category->...
//add columns what you need to save in table
if($this->save($category)){
return true;
}else{
return false;
}
}
