Woocommerce自定义帐户页面初始化操作会在每个页面上显示字段错误

如何解决Woocommerce自定义帐户页面初始化操作会在每个页面上显示字段错误

我正在创建自定义woocommerce注册页面。客户可以使用姓名，电子邮件和手机号码创建帐户。这三个字段都是必填字段。

这是我的代码：

add_action('init','devsol_customer_auth_register');
function devsol_customer_auth_register() {
    $customer_name = sanitize_text_field( $_POST['reg_billing_name'] );
    $customer_phone = sanitize_text_field( $_POST['reg_billing_phone'] );
    $customer_email = sanitize_email( $_POST['reg_billing_email'] );
    $customer_password = wp_generate_password( 12,false );
    $noemail = '';

if (isset( $_POST['reg_billing_name'] ) && empty( $_POST['reg_billing_name'])) {
    $GLOBALS['ERROR'] = 'register-name';
    } 
else if (isset( $_POST['reg_billing_email'] ) && empty( $_POST['reg_billing_email'])) {
    $GLOBALS['ERROR'] = 'register-email';
    }  

else if (email_exists($customer_email)) {
        $GLOBALS['ERROR'] = 'register-email-exist';  
}

else if (isset( $_POST['reg_billing_phone'] ) && empty( $_POST['reg_billing_phone'])) {
    $GLOBALS['ERROR'] = 'register-phone';
    }    

else if ((!preg_match('/^[0-9]{11}$/D',$_POST['reg_billing_phone'] )) && !empty( $_POST['reg_billing_phone'])) {
    $GLOBALS['ERROR'] = 'register-phone-validation';    
    }

else if (!username_exists($customer_phone)) {       
        $user_id = wp_create_user($customer_phone,$customer_password,$noemail);   
        if ( !is_wp_error( $user_id ) ) {          
        if ( apply_filters( 'woocommerce_registration_auth_new_customer',true,$user_id ) ) {
        wc_set_customer_auth_cookie( $user_id );
        }
        update_user_meta($user_id,'billing_first_name',$customer_name);
        update_user_meta($user_id,'billing_email',$customer_email);
        update_user_meta($user_id,'billing_phone',$customer_phone);
        wp_update_user (array( 
            'ID' => $user_id,'first_name' => $customer_name,'display_name' => $customer_name,'nickname' => $customer_name,'role' => 'customer',));  
        }        
    }   
    else {
        $GLOBALS['ERROR'] = 'duplicate-register';         
    }  
}

这是输出：

我在每个页面上都收到此错误

Notice: Undefined index: reg_billing_name in /Applications/AMPPS/www/flatsome/wp-content/plugins/devsol-auth-customer/index.php on line 110

Notice: Undefined index: reg_billing_phone in /Applications/AMPPS/www/flatsome/wp-content/plugins/devsol-auth-customer/index.php on line 111

Notice: Undefined index: reg_billing_email in /Applications/AMPPS/www/flatsome/wp-content/plugins/devsol-auth-customer/index.php on line 112

Notice: Undefined index: reg_billing_phone in /Applications/AMPPS/www/flatsome/wp-content/plugins/devsol-auth-customer/index.php on line 131

请帮助。

解决方法

您到处都可以看到该通知，因为devsol_customer_auth_register函数已挂接到init中，每次加载WordPress时都会触发该功能。可能会使用更好的钩子。

add_action('init','devsol_customer_auth_register');

第二，通知来自这些行，因为$ _POST变量在将变量设置为等于它们时不存在。

    $customer_name = sanitize_text_field( $_POST['reg_billing_name'] );
    $customer_phone = sanitize_text_field( $_POST['reg_billing_phone'] );
    $customer_email = sanitize_email( $_POST['reg_billing_email'] );

为避免这种情况，请先检查变量是否存在。

    $customer_name  = null;
    $customer_phone = null;
    $customer_email = null;
    if ( isset( $_POST['reg_billing_name'] ) ) {
       $customer_name = sanitize_text_field( $_POST['reg_billing_name'] );
    }
    if ( isset( $_POST['reg_billing_phone'] ) ) {
       $customer_name = sanitize_text_field( $_POST['reg_billing_phone'] );
    }
    if ( isset( $_POST['reg_billing_email'] ) ) {
       $customer_name = sanitize_text_field( $_POST['reg_billing_email'] );
    }

最后，这是一个片段，应注意添加这些额外的配置文件字段

function woocommerce_edit_my_account_page() {
    return apply_filters( 'woocommerce_forms_field',array(
        'woocommerce_reg_billing_name' => array(
            'type'        => 'text','label'       => __( 'Reg Billing Name','textdomain' ),'placeholder' => __( 'Billing Name','required'    => false,),'woocommerce_reg_billing_phone' => array(
            'type'        => 'text','label'       => __( 'Reg Billing Phone','placeholder' => __( 'Billing Phone','woocommerce_reg_billing_email' => array(
            'type'        => 'text','label'       => __( 'Reg Billing Email','placeholder' => __( 'Billing Email',) );
}
function edit_my_account_page_woocommerce() {
    $fields = woocommerce_edit_my_account_page();
    foreach ( $fields as $key => $field_args ) {
        woocommerce_form_field( $key,$field_args );
    }
}
add_action( 'woocommerce_register_form','edit_my_account_page_woocommerce',15 );
