Question

我正在尝试使用cakephp模型实现表单验证。这是我的代码片段......

模型

// File: /app/models/enquiry.php
class Enquiry extends AppModel {
    var $name = "Enquiry";
    var $useTable = false;
    var $_schema = array(
        "name"      => array( "type" => "string", "length" => 100 ), 
        "phone"     => array( "type" => "string", "length" => 30 ), 
        "email"     => array( "type" => "string", "length" => 255 )
    );
    var $validate = array(
    'name' => array(
        'rule' => 'notEmpty',
        'required' => true,
        'message' => 'Name is required'
    ),
    'email' => array(
        'emailFormat' => array(
            'rule' => 'notEmpty',
            'required' => true,
            'message' => 'Email is required'
        ),
        'emailNeeded' => array(
            'rule' => array('email', true),
            'required' => true,
            'message' => 'Must be a valid email address'
        )
    )
    );
}

控制器操作

// /app/controllers/nodes_controller.php
class NodesController extends AppController {

    var $name = "Nodes";
    var $uses = array( "Enquiry" );
    function enquire() {
        if ( $this->data ) {
           $this->Enquiry->set( $this->data );
            if ( $this->Enquiry->validates() ) {
            // .....
            } else {
                 $this->set("errors", $this->Enquiry->invalidFields());
            }
        }
    }
}

查看...

// /app/views/nodes/enquire.ctp
<?php echo $form->create("Node", array("action" => "ask")); ?>
<?php echo $form->input("name", array(
                            "error" => array( "class" => "error-message" ),
                            "div" => false,
                            "label" => "Name",
                            "size" => "40"
                        ) ); ?>
<?php echo $form->input("email", array(
                            "error" => array( "class" => "error-message" ),
                            "div" => false,
                            "label" => "Email",
                            "size" => "40"
                        ) ); ?>
<?php echo $form->input("phone", array(
                            "label" => "Phone No.",
                            "div" => false,
                            "size" => "30"
                        ) ); ?>
<?php echo $form->end("Send");?>

我的问题：在提交时，表单验证发生，Model-＆gt; validates方法返回false，但验证错误永远不会显示。我检查了invalidFields（）返回的数组，我在模型中设置的所有错误消息都在那里，但它们没有显示....

我做错了什么？

此致

对我来说，问题出在你的表格标签上。

基本上，如果您验证查询，公司字段应具有以下名称：data [Inquiry] [name]而不是data [Node] [name]。

如果你改变了

<?php echo $form->create("Node", array("action" => "ask")); ?>

到

<?php echo $form->create("Enquiry", array("action" => "ask")); ?>

错误应该出现在核心。

如果您的表单混合了Node和Inquiry字段，那么只需将Model的名称放在字段名称前面，如下所示：

<?php echo $form->input("Enquiry.email", array(....));?>

Cakephp：验证错误未出现在数据验证中
