Cakephp数据验证“；notEmpty“&引用；“必需”；

我是一个菜鸟蛋糕，完成了博客教程，现在我正在尝试一些简单的开始。 但我有点不明白。 在model PersonalInformation上，我得到了表字段的数据验证：

这是我的带有$validate数组的模型：

class PersonalInformation extends AppModel {

/**
 * Validation rules
 * @var $validate
 */
public $validate = array(
    "first_name" => array(
        "name"      => array(
            "rule"      => "validName",
            "message"   => 'Only alpha characters and "." (dots)',
        ),
    ),
    "last_name"  => array(
        "name"      => array(
            "rule"      => "validName",
            "message"   => 'Only alpha characters and "." (dots)',
        ),
    ),
    "birth_date" => array(
        "date"      => array(
            "rule"      => "date",
            "message"   => "Enter a valid date",
        ),
    ),
    "nickname"  => array(
        "alphanumeric"  => array(
            "rule"      => "alphaNumeric",
            "message"   => "Only alpha-numeric characters",
        ),
    ),
    "gender"     => array(
        "notEmpty"  => array(
            "rule"          => "notEmpty",
            "message"       => "Can't be empty",
        ),
    ),
);

} // end class

'gender' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Can\'t be empty.'
            )
        )

这是我的桌子：

CREATE TABLE `personal_informations`
(
`id` INT NOT NULL UNIQUE AUTO_INCREMENT,
`first_name` VARCHAR(45),
`last_name` VARCHAR(45),
`birth_date` DATE,
`nickname` VARCHAR(45),
`is_company` TINYINT DEFAULT 0 NOT NULL,
`picture_url` VARCHAR(255),
`gender` ENUM('m','f') NOT NULL,
`notes` TEXT,
`created` DATETIME,
`modified` DATETIME,
PRIMARY KEY (`id`)
) ENGINE=InnoDB CHARACTER SET=utf8;

CREATE INDEX `id_idx` ON personal_informations(id);

以下是观点：

<!-- /PersonalInformations/add -->

<div class="">
<h2>Create a personal information</h2>
    <?php
    echo $this->Form->create();

    echo $this->Form->input( "PersonalInformation.first_name" );
    echo $this->Form->input( "PersonalInformation.last_name" );
    echo $this->Form->input( 
        "PersonalInformation.birth_date", 
        array( 
            "separator" => " - ", 
            "minYear" => date('Y') - 90,
            "maxYear" => date('Y')
    )
    );
    echo $this->Form->input( "PersonalInformation.nickname" );
    echo $this->Form->input( "PersonalInformation.is_company", array( "type" =>     "checkbox" ));
    echo $this->Form->input( "PersonalInformation.piture_url", array( "type" => "file"     ));
    echo $this->Form->radio( "PersonalInformation.gender", array( "m" => __("Male"), "f"     => __("Female")), array( "hiddenField" => false ));
    echo $this->Form->textarea( "PersonalInformation.notes" );

    echo $this->Form->end( "Done" );
    ?>
</div>

创建个人信息

所以问题是，出于某种原因，“昵称”是必需的，我的意思是，当我点击“昵称”为空的提交按钮时，它只显示“字母数字字符”。 对于“性别”，如果没有选择，则不会显示任何内容

如果还有什么我需要发布的，请告诉我。

对于昵称，您是否尝试使用

required=>false

？ 你可以阅读更多关于它的内容

为了你的绰号

'nickname' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Nick name is required.'
            )
        )

性别：

在视图中

echo $this->Form->input('PersonalInformation.gender',array(
          'type'=>'select','empty' => '---- Select----',
          'class'=>'select',
          'options'=>$option_array
          ))

在模型验证阵列中：

class PersonalInformation extends AppModel {

/**
 * Validation rules
 * @var $validate
 */
public $validate = array(
    "first_name" => array(
        "name"      => array(
            "rule"      => "validName",
            "message"   => 'Only alpha characters and "." (dots)',
        ),
    ),
    "last_name"  => array(
        "name"      => array(
            "rule"      => "validName",
            "message"   => 'Only alpha characters and "." (dots)',
        ),
    ),
    "birth_date" => array(
        "date"      => array(
            "rule"      => "date",
            "message"   => "Enter a valid date",
        ),
    ),
    "nickname"  => array(
        "alphanumeric"  => array(
            "rule"      => "alphaNumeric",
            "message"   => "Only alpha-numeric characters",
        ),
    ),
    "gender"     => array(
        "notEmpty"  => array(
            "rule"          => "notEmpty",
            "message"       => "Can't be empty",
        ),
    ),
);

} // end class

'gender' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Can\'t be empty.'
            )
        )

为昵称规则添加

'allowEmpty'=>true

 "nickname"  => array(
        "alphanumeric"  => array(
            "allowEmpty"=> true,
            "rule"      => "alphaNumeric",
            "message"   => "Only alpha-numeric characters",
        ),
    ),

关于性别，我会尽快测试，但关于昵称，我不希望它是必需的，但出于某种原因，它看起来像是在我点击提交时，因为它不允许我在没有填写输入的情况下提交。关于昵称，您到底需要什么功能。请注意，根据文档，“notEmpty”在2.7版之后被弃用。替换它的函数为“notBlank”。对于第一个问题没有任何解释，“允许免费”有效。我以前试过，问题是它不在昵称数组中，我刚刚注意到在ADmad post Thank all（不幸的是，我无法投票支持）上，实际上，“required”不是他想要的。从您链接到的文档中可以看出：“required和allowEmpty之间的差异可能会令人困惑。'required'=>true表示如果$this->data中没有此字段的键，则无法保存模型（使用isset执行检查）；然而，'allowEmpty'=>false确保当前字段值为非空，如上所述。”
