Question

这是我的例子

<?php
/* 
Template Name: SQL Templatess
*/
get_header();
global $wpdb;

/**
 * Function is used to select fields from BarZap and ICMOrders database.
 */
function selectDatas($Fields) {
    global $wpdb;
    $slectSQL = "SELECT $Fields
    FROM barZapp.Venue AS venue
    INNER JOIN ICMOrders.Customer AS customer ON customer.ID = venue.CustomerId
    INNER JOIN ICMOrders.Order AS orderP ON customer.ID = orderP.CustomerID
    WHERE orderP.OrderType='BarZapp' GROUP BY orderP.CustomerID";
    return $slectSQL;
}

$insert4User = selectDatas("customer.ID,customer.Name,venue.password,customer.EmailAddress,venue.creationdate,venue.country,
    venue.state, venue.city, venue.zip, venue.contactphone");
$selectQuery = $wpdb->get_results($insert4User, OBJECT );

foreach ($selectQuery as $keyValues) {
    $result = $wpdb->insert( 
        $wpdb->prefix . 'users', 
        array( 
            'spam'            => 0, 
            'user_status'     => 0, 
            'deleted'         => 0, 
            'old_user_id'     =>$keyValues->ID,
            'user_login'      =>$keyValues->Name, 
            'user_pass'       =>$keyValues->password,
            'user_nicename'   =>$keyValues->Name, 
            'user_email'      =>$keyValues->EmailAddress, 
            'display_name'    =>$keyValues->Name, 
            'user_registered' =>$keyValues->creationdate, 
        )
    );
        $user_id = $wpdb->insert_id; ## Get the last inserted ID of user's
        $forUserrole = new WP_User( $user_id );

        add_user_meta( $user_id, 'nickname', $keyValues->Name);
        add_user_meta( $user_id, 'first_name', $keyValues->Name);
        add_user_meta( $user_id, 'rich_editing', true);
        add_user_meta( $user_id, 'admin_color', 'fresh');
        add_user_meta( $user_id, 'use_ssl', 0);
        add_user_meta( $user_id, 'show_admin_bar_front', 0);
        add_user_meta( $user_id, 'ic_capabilities', $forUserrole->set_role('Multi')); 
        add_user_meta( $user_id, 'ic_user_level', 0);
        add_user_meta( $user_id, 'billing_first_name', $keyValues->Name);
        add_user_meta( $user_id, 'billing_email',$keyValues->EmailAddress);
        add_user_meta( $user_id, 'billing_phone', $keyValues->contactphone);
        add_user_meta( $user_id, 'billing_state', $keyValues->state);
        add_user_meta( $user_id, 'billing_city', $keyValues->city);
        add_user_meta( $user_id, 'billing_zip', $keyValues->zip);
        add_user_meta( $user_id, 'billing_country', $keyValues->country);
}
get_footer();

现在我可以将此class User < ActiveRecord::Base validates_with EmailValidator end class EmailValidator < ActiveModel::Validator def validate(record) if record != someregex record.errors.add(:email, 'invalid email') end end end用于任何模型。但我的要求是验证其特定模型的独特性和存在性。

如果我能做到这一点，我可以使用此EmailValidator进行任何模型电子邮件验证，其功能是唯一的，存在。

然后我可以实现更多可重用的Validator。

您可以将验证程序重写为EachValidator：

class EmailValidator < ActiveModel::EachValidator
  def validate_each(record, attribute, value)
    if attribute !~ someregex
      record.errors.add attribute, (options[:message] || 'invalid email')
    end
  end
end

然后在你的模型中：

validates :email, email: true, uniqueness: true, presence: true

希望有所帮助。
