WordPress自定义问题：未定义索引

Question

  

注意：未定义索引：名称在   G：\ aservera \ htdocs \ WP \ woocommerce \ wp-content \ plugins \ custom-post \ custom_post.php   在第78行

     

注意：未定义索引：以电子邮件发送   G：\ aservera \ htdocs \ WP \ woocommerce \ wp-content \ plugins \ custom-post \ custom_post.php   在第79行

我的代码：

function wpdocs_my_display_callback($post){

    $name =get_post_meta($post->ID,'muvies_name',true);
    $email =get_post_meta($post->ID,'muvies_email',true);
    ?>
        <label for="">name:</label>
        <input type="text" name="name" value="<?php echo $name;?>">
        <br>

        <label for="">email:</label>
        <input type="text" name="email" value="<?php echo $email;?>">

    <?php
}
function data_save($post_id,$post){

    $name = $_POST['name'];
    $email = $_POST['email'];

    update_post_meta($post_id,'muvies_name', $name);
    update_post_meta($post_id,'muvies_email', $email);
}
add_action('save_post','data_save',10,2);
