CAKEPHP：錯誤：SQLSTATE [42000]：語法錯誤或訪問衝突：1064您的SQL語法中有錯誤;

Question

我試圖用read()函數讀取我的表中的一行，這給了我一個錯誤。我試着使用find('all')，但同樣的事情發生：

Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax;

型號Article.php

class Article extends AppModel { 

     function index() { 

     } 
    } 

控制器ArticlesController.php

class ArticlesController extends AppController { 

    public $uses = array('Article', 'User'); 

    public function view() { 
     $id = $this->request->params['id']; 

     $this->Article->recursive = 3; 
     $this->Article->id = $id; 
     $articl = $this->Article->read(); 

     echo count($articl); 
     exit; 
    } 

    } 

任何人可以幫助我嗎？

線

$id = $this->request->params['id']; 

不正確。然而，

$id = $this->request->params['named']['id']; 

將工作，如果你的電話看起來像/articles/view/id:1。

在CakePHP中，它更易於使用Passed Arguments。參數從URL中提取並傳遞給操作。你的情況：

class ArticlesController extends AppController { 

    public $uses = array('Article', 'User'); 

    public function view($id) { 

     //$this->Article->recursive = 3; // does not apply, only needed with Model->find 
     $this->Article->id = $id; 
     $article = $this->Article->read(); //will return a single row    
    } 

} 

通過調用/articles/view/1，該view行動將檢索來自articles表id=1。
