Question

print_r($products);

返回：

Array ( [1] => 1 [2] => 2 [3] => 3 [4] => 4 [5] => 5 [6] => 6 [7] => 7 [8] => 8 [9] => 9 [10] => 10 [11] => 11 [12] => 12 [13] => 13 )

** ......错了。它必须是**

[1] => product_item_1, 
[2] => product_item_2, ....etc.....

为什么数组错了？

KlientsController.php：

class KlientsController extends AppController {
     var $name = 'Klients';
     var $scaffold;

public $helpers = array('Html', 'Form', 'Session', 'Form');
public $components = array('Session');

  public function newedit($id = null) {
      $this->Klient->recursive = 1;
      $this->loadModel('Product');
      $products=$this->Product->find('list',
                array('Product.id','Product.product_name'));

Klient.php（型号）：

   `class Klient extends AppModel {
       var $name = 'Klient';
        var $belongsTo = array('Product');

 function newedit($id = null){    
        $products = $this->Klient->Product->generateList();       
        $this->set('products', $products);

}

newedit.ctp：

 echo $this->Form->input('product_id', 
                 array('options' => $products));

这个下拉列表包含13个项目，这是正确的，但它是空的....为什么？

Answer 1

我没看到字段

$products=$this->Product->find('list',
              array('fields' => array('Product.id','Product.product_name')));

数组是空的，关系一对多，cakephp
