cakePHP 验证根本不起作用

Question

蛋糕版本2.0

我正在做一个 cakePHP 项目，我无法让验证功能正常工作。

我通过订单控制器向付款table（模型）提交数据。

这是视图。

echo $this->Form->create("Payment",array("class"=>"payment"));
    echo $this->Form->input("Payment.PaymentID");
    echo $this->Form->input("Payment.OrderID",array("value"=>$order["Order"]["OrderID"],"type"=>"hidden"));
    echo $this->Form->input("Payment.UserID",array("type"=>"hidden","value"=>$loggedInUserID));
    echo $this->Form->input("Payment.TransactionTypeID",array("class"=>"transaction","options"=>$transactions,"label"=>"Transaction Type","empty"=>"Select Transaction Type"));

    echo $this->Html->div("transactionType Phone");
        echo $this->Form->input("Payment.NameOnCheck",array("class"=>"CheckBy Phone"));
        echo $this->Form->input("Payment.CheckRoutingNumber");
        echo $this->Form->input("Payment.CheckAccountNumber");  
    echo "</div>";

    echo $this->Html->div("transactionType CreditCard clearfix");
        echo $this->Form->input("Payment.CreditCardNumber",array("label"=>"Card Number"));
        echo $this->Form->input("CreditCardExpirationMonth",array("label"=>"Expiration Date","options"=>$months));
        echo $this->Form->input("CreditCardExpirationYear",array("label"=>" ","options"=>$years));
        echo $this->Form->input("Payment.CreditCardExpirationDate",array("type"=>"hidden"));
        echo $this->Form->input("Payment.CreditCardCVV",array("label"=>"CVV (not required)","class"=>"noCharge"));
        echo $this->Form->input("Payment.CreditCardStreet",array("label"=>"Street Address on Card (not required)","class"=>"noCharge"));
        echo $this->Form->input("Payment.CreditCardZipCode",array("Zip Code","class"=>"noCharge"));
    echo "</div>";

    echo $this->Html->div("transactionType AmountPaid clearfix");
        echo $this->Form->input("Payment.PaymentAmount",array("label"=>"Amount Paid"));
        echo $this->Form->input("Pay In Full",array("type"=>"button","label"=>" "));
    echo "</div>";

    echo $this->Html->div("transactionType RefundAmount");
        echo $this->Form->input("RefundAmount",array("label"=>"Amount To Refund"));
    echo "</div>";



echo $this->Form->end("Complete Transaction");

控制器

 $this->Order->Payment->set($this->request->data);
        if($this->request->is("post") || $this->request->is("put")) {



            if($this->Order->Payment->save($this->request->data)){
                $this->Session->setFlash("Payment Added");
               //$this->redirect("add_payment/$id");
            }

        }

支付模式

class Payment extends AppModel{
public $useTable = "Payment";
public $primaryKey = "PaymentID";
public $belongsTo = array(
    "TransactionType"=>array(
        "foreignKey"=>"TransactionTypeID"
    )
);
    public $validate = array(
        "NameOnCheck" => array(
            "rule" => "notBlank"
        )
    );

其中一个问题是，每当我在 NameOnCheck 字段中提交包含数据的表单时，它都会给我一个错误提示，指出该字段为空白。

它也没有考虑我设置的所有验证。当我对 CheckRoutingNumber 的长度进行验证时，它只是忽略它并且只给我一个 NameOnCheck 的错误（无论是否填写）。

我也在顶部收到两次警告：

preg_match(): Delimiter must not be alphanumeric or backslash [CORE/Cake/Model/Model.php, line 3198]

有没有人对此有解决方案，我们将不胜感激！谢谢！

除非您在其他地方定义了它，否则规则 notBlank 应该是 notEmpty 以使字段成为必需的（对于低于 2.7 的 CakePHP，如您的情况）：-

public $validate = array(
    "NameOnCheck" => array(
        "rule" => "notEmpty"
    )
);

Cake 向您显示错误消息 preg_match(): Delimiter must not be alphanumeric or backslash，因为 notBlank 不是您应用中定义的规则，因此将其视为自定义正则表达式规则。

正如 Dave 在他对 CakePHP 2.7+ 的评论中所述，您应该使用 notBlank.
