我开发了一个customer metabox插件，将用户详细信息保存到db中，并在我的网站中检索回“联系我们”页面。

但我搜索了一种方法来检索“联系我们”页面上的数据，但我找不到方法。

请查看此代码，并告诉我如何检索通过metabox.php 到page-contact.php

metabox.php

<?php

add_action(\'add_meta_boxes\', \'wpl_owt_register_metabox_cpt\');
function wpl_owt_register_metabox_cpt()
{
    global $post;

    if(!empty($post))
    {
        $pageTemplate = get_post_meta($post->ID, \'_wp_page_template\', true);

        if($pageTemplate == \'page-contact.php\' )
        {
            add_meta_box(
                \'owt-cpt-id\', // $id
                \'Contact Details\', // $title
                \'wpl_owt_book_function\', // $callback
                \'page\', // $page
                \'normal\', // $context
                \'high\'); // $priority
        }
    }
}


   /**********Callback function for metabox at custom post type book******************/

 function wpl_owt_book_function( $post ) {
    //echo "<p>Custom metabox for custom post type</p>";

    define("_FILE_", "_FILE_");

    wp_nonce_field( basename(_FILE_), "wp_owt_cpt_nonce");

    echo "<label for=\'txtPhoneNum\'>Phone</label><br>";
    $phone_num = get_post_meta($post->ID, "telNo" , true);
    echo "<input type =\'tel\' name = \'txtPhoneNum\' value = \'" . $phone_num . "\'\' placeholder = \'Phone Number\' /><br><br>";

    echo "<label for=\'txtEmail\'>Email</label><br>";
    $email = get_post_meta($post->ID, "email" , true);
    echo "<input type =\'email\' name = \'txtEmail\' value = \'" . $email . "\'\' placeholder = \'Email Address\' /><br><br>";

    echo "<label for=\'txtHours\'>Hours of Operation</label><br>";
    $hours = get_post_meta($post->ID, "hourofOps" , true);
    echo "<input type =\'text\' name = \'txtHours\' value = \'" . $hours . "\'\' placeholder = \'Working Hours\' /><br><br>";
}

add_action("save_post" , "wpl_owt_save_metabox_data" , 10 , 2);

function wpl_owt_save_metabox_data($post_id, $post){

    //verify nonce
    if(!isset($_POST[\'wp_owt_cpt_nonce\']) || !wp_verify_nonce($_POST[\'wp_owt_cpt_nonce\'], basename(_FILE_))){
        return $post_id;
    }

    //verify slug value
    $post_slug = "page";
    if($post_slug != $post->post_type){
        return;
    }

    //save value to db filed
    $pub_tel = \'\';
    if(isset($_POST[\'txtPhoneNum\'])){
        $pub_tel = sanitize_text_field($_POST[\'txtPhoneNum\']);
    }

    else{
        $pub_tel = \'\';
    }

    update_post_meta($post_id, "telNo", $pub_tel);


    $pub_email = \'\';

    if(isset($_POST[\'txtEmail\'])){
        $pub_email = sanitize_text_field($_POST[\'txtEmail\']);
    }

    else{
        $pub_email = \'\';
    }

    update_post_meta($post_id, "email", $pub_email);


    $pub_hours = \'\';

    if(isset($_POST[\'txtHours\'])){
        $pub_hours = sanitize_text_field($_POST[\'txtHours\']);
    }
    update_post_meta($post_id, "hourofOps", $pub_hours);
}

?>
