Question

我的控制器类

 class BlistsController extends AppController{

    public $components = array('session');
    public function index(){
       $data = $this->Blist->find('all');
       $this->set('var_Blist', $data);
    }

    public function add(){
        print_r($this->request->data);

        if($this->request->is(array ('post', 'put'))){
            $this->Blist->create();
            if($this->Blist->save($this->request->data)){
                $this->session->setFlash("book added successfully");
                $this->reirect('index');
            }
            else{
                $this->session->setFlash("Unable to add book");
            }               
        }
    }
}

我在家用电脑上使用过此代码。它的工作正常。但是同样的代码在我的工作场所不起作用。在wamp中是否有任何启用需求。

当我打印print_r($this->request->data)时它显示

Array ( [Blist] => Array ( [F_bookId] => [F_name] => sadfasdf [F_author] => asdfasdf ) )

字段“F_bookId”在数据库表中自动递增。因此它不会显示在显示页面上。

App::uses('AppModel', 'Model');
/**
 * Blist Model
 *
 */
class Blist extends AppModel {

/**
 * Primary key field
 *
 * @var string
 */
    public $primaryKey = 'F_bookId';

/**
 * Display field
 *
 * @var string
 */
    public $displayField = 'F_name';

/**
 * Validation rules
 *
 * @var array
 */
    public $validate = array(
        'F_bookId' => array(
            'notEmpty' => array(
                'rule' => array('notEmpty'),
                //'message' => 'Your custom message here',
                //'allowEmpty' => false,
                //'required' => false,
                //'last' => false, // Stop validation after this rule
                //'on' => 'create', // Limit validation to 'create' or 'update' operations
            ),
        ),
        'F_name' => array(
            'notEmpty' => array(
                'rule' => array('notEmpty'),
                //'message' => 'Your custom message here',
                //'allowEmpty' => false,
                //'required' => false,
                //'last' => false, // Stop validation after this rule
                //'on' => 'create', // Limit validation to 'create' or 'update' operations
            ),
        ),
        'F_author' => array(
            'notEmpty' => array(
                'rule' => array('notEmpty'),
                //'message' => 'Your custom message here',
                //'allowEmpty' => false,
                //'required' => false,
                //'last' => false, // Stop validation after this rule
                //'on' => 'create', // Limit validation to 'create' or 'update' operations
            ),
        ),
    );
}

Add.ctp

  <h1> Add Book Details </h1>
<?php
 echo $this->Form->create('Blist');
 echo $this->Form->input('F_bookId');
 echo $this->Form->input('F_name');
 echo $this->Form->input('F_author');
 echo $this->Form->end('Add Book');
?>

最终代码正常工作..

 public function add(){             

    $data = $this->request->data;//getting the values from the input fields

    //get the last record
    $lastRecordId = $this->Blist->find('first', array('order' =>array('F_bookId' => 'DESC')));

    //Split the book id, to generate a new book id
    $temp = str_split($lastRecordId['Blist']['F_bookId'], '4');        
    $data['Blist']['F_bookId'] = ($temp[0]. ((String)((int)$temp[1]+1)));

    if($this->request->is(array ('post', 'put'))){           
        $this->Blist->create();                        
        if($this->Blist->save($data)){
            $this->session->setFlash("book added successfully");
            $this->redirect('add');
        }
        else{
            debug($this->Blist->validationErrors);
            $this->session->setFlash("Unable to add book");
        }               
    }
}

您的ID由数据库的自动增量功能自动创建。没有必要验证F_BookId的用户输入，因为没有，如果在该字段上设置规则notEmpty验证将触发错误。

从$ validate数组中删除此部分：

    'F_bookId' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
            //'message' => 'Your custom message here',
            //'allowEmpty' => false,
            //'required' => false,
            //'last' => false, // Stop validation after this rule
            //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
    ),

这应该让你保存书籍。
