Question

我在这里编写了我的第一个wordpress插件代码：

    <?php
// If this file is called directly, abort.
if ( ! defined( 'WPINC' ) ) {
    die;
}

define( 'PLUGIN_NAME_VERSION', '1.0.0' );

/**
 * The code that runs during plugin activation.
 * This action is documented in includes/class-post-time-changer-activator.php
 */
function activate_post_time_changer() {
    require_once plugin_dir_path( __FILE__ ) . 'includes/class-post-time-changer-activator.php';
    Post_Time_Changer_Activator::activate();
}

/**
 * The code that runs during plugin deactivation.
 * This action is documented in includes/class-post-time-changer-deactivator.php
 */
function deactivate_post_time_changer() {
    require_once plugin_dir_path( __FILE__ ) . 'includes/class-post-time-changer-deactivator.php';
    Post_Time_Changer_Deactivator::deactivate();
}

register_activation_hook( __FILE__, 'activate_post_time_changer' );
register_deactivation_hook( __FILE__, 'deactivate_post_time_changer' );

/**
 * The core plugin class that is used to define internationalization,
 * admin-specific hooks, and public-facing site hooks.
 */
require plugin_dir_path( __FILE__ ) . 'includes/class-post-time-changer.php';

/**
 * Begins execution of the plugin.
 *
 * Since everything within the plugin is registered via hooks,
 * then kicking off the plugin from this point in the file does
 * not affect the page life cycle.
 *
 * @since    1.0.0
 */
function run_post_time_changer() {

    $plugin = new Post_Time_Changer();
    $plugin->run();

}
run_post_time_changer();


add_action('admin_menu', 'PTC_setup_menu');

function PTC_setup_menu(){
        add_menu_page( 'Post Time Changer', 'PostTimeChanger', 'manage_options', 'post-time-changer', 'ptc_option_page' );
}
global $ptc_db_version;
$ptc_db_version = '1.0';


//install database table 
function ptc_install() {
    global $wpdb;
    global $ptc_db_version;

    $table_name = $wpdb->prefix . 'concilium';

    $charset_collate = $wpdb->get_charset_collate();

    $sql = "CREATE TABLE $table_name (
        id mediumint(9) NOT NULL AUTO_INCREMENT,
        hours tinytext NOT NULL,
        minutes tinytext NOT NULL,
        PRIMARY KEY  (id)
    ) $charset_collate;";

    require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
    dbDelta( $sql );

    add_option( 'ptc_db_version', $ptc_db_version );
}
//initial database data
function ptc_install_data() {
    global $wpdb;

    $hours = '6';
    $minutes = '12';

    $table_name = $wpdb->prefix . 'concilium';

    $wpdb->insert( 
        $table_name, 
        array( 

            'hours' => $hours, 
            'minutes' => $minutes, 
        ) 
    );
}


function ptc_table_check(){
    global $wpdb;
    $table_name = $wpdb->prefix . 'concilium';
$checktable = mysql_query('select 1 from' . $table_name );
if($checktable !== FALSE)
{
    ptc_install();
    echo "database installed!";
}else{
    ptc_update_data();
    echo "data upadated!";
}

}

//update data
function ptc_update_data(){
    global $wpdb;
    $hours = $_POST['hours'];
    $minutes = $_POST['minutes'];
    $table = 'wp_concilium';
    $rows = $wpdb->update( 
    $table, 
    array( 
        'hours' => $hours,  // string
        'minutes' => $minutes   // integer (number) 
    ), 
    array( 'ID' => 1 ), 
    array( 
        '%s',   // value1
        '%d'    // value2
    ), 
    array( '%d' ) 
);
}

function ptc_option_page(){
        ?>
            <div class="wrap">
            <h1>Post Time Changer</h1>
            <?php 
            global $wpdb;
            $result = $wpdb->get_results ( "SELECT * FROM wp_concilium");
            foreach ( $result as $print) {
                ?>

            <?php
            }
            ?>
            <form action="<?php ptc_update_data(); ?>" method="post">
            <?php settings_fields('plugin_options'); ?>
            <?php do_settings_sections('plugin'); ?>


<!-- amount of time the post should be anticipated -->

set the amount of Hours you want your post to be anticipated <input name="hours" type="number" value="" /><br/>
set the amount of minutes you want your post to be anticipated <input name="minutes" type="number" value="" /><br/>
<tr>
                <td><h2>currently set to</h2></td>
                <td><?php echo $print->hours;?> hours</td>
                <td><?php echo $print->minutes;?> minutes</td>
            </tr><b/>
<!--save setting on the bottom -->
<input name="Submit" type="submit" value="update" />
</form></div>
<?php
add_action('admin_init', 'plugin_admin_init');
function plugin_admin_init(){
register_setting( 'plugin_options', 'plugin_options', 'plugin_options_validate' );
add_settings_section('plugin_main', 'Main Settings', 'plugin_section_text', 'plugin');
add_settings_field('plugin_text_string', 'Plugin Text Input', 'plugin_setting_string', 'plugin', 'plugin_main');


}

}

插件会更新数据库，其中包含我希望发布帖子的小时和分钟数，以便人们可以认为我已经在实际时间之前几个小时发布了。代码正常工作，因为在代码部分：

             <tr>
                <td><h2>currently set to</h2></td>
                <td><?php echo $print->hours;?> hours</td>
                <td><?php echo $print->minutes;?> minutes</td>
            </tr><b/>

它没有显示它在数据库中保存的正确时间，但是当我重新加载页面时它显示了保存的时间，这是我重新加载数据库字段时的另一个问题返回0

我该如何解决这个问题？
