Question

我试图使用read()函数读取我的表格中的一行，这给了我一个错误。我曾尝试使用find('all')，但同样的事情发生了：

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

Model Article.php

    class Article extends AppModel {

      function index() {

      }
    }

Controller 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;
    }

  }

有人可以帮帮我吗？

该行

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

不正确。然而

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

如果您的通话看起来像/articles/view/id:1，

将会有效。

在CakePHP中，使用Passed Arguments更容易。参数从URL中提取并传递给操作。在你的情况下：

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            
    }

}

通过致电/articles/view/1，view操作将从id=1表中检索articles。
