源码介绍

将其添加到 WordPress 主题的 functions.php 文件中：

function custom_publish_actions() {
    // 添加复选框到发布元框
    echo '<div id="custom-publish-time-option" style="padding:10px;">
            <label>
                <input type="checkbox" name="custom_publish_time_checkbox" id="customPublishTimeCheckbox" value="yes" onchange="autoUpdateTime();" />
                自动更新发布时间
            </label>
          </div>';
    // JavaScript 自动更新发布时间
    echo '<script type="text/javascript">
            function autoUpdateTime() {
                if (document.getElementById("customPublishTimeCheckbox").checked) {
                    var currentDate = new Date();
                    document.getElementById("aa").value = currentDate.getFullYear();
                    document.getElementById("mm").value = ("0" + (currentDate.getMonth() + 1)).slice(-2);
                    document.getElementById("jj").value = ("0" + currentDate.getDate()).slice(-2);
                    document.getElementById("hh").value = ("0" + currentDate.getHours()).slice(-2);
                    document.getElementById("mn").value = ("0" + currentDate.getMinutes()).slice(-2);
                } else {
                    // Optionally clear fields or set to original values
                }
            }
          </script>';
}
 
function update_post_date_on_publish($data, $postarr) {
    // 检查复选框是否被勾选并更新发布时间
    if (isset($_POST['custom_publish_time_checkbox']) && $_POST['custom_publish_time_checkbox'] == 'yes' && $data['post_status'] == 'publish') {
        $current_time = current_time('mysql');
        $data['post_date'] = $current_time;
        $data['post_date_gmt'] = get_gmt_from_date($current_time);
    }
    return $data;
}
 
// 添加动作钩子到发布框
add_action('post_submitbox_misc_actions', 'custom_publish_actions');
// 添加过滤器以检查复选框状态并更新发布时间
add_filter('wp_insert_post_data', 'update_post_date_on_publish', 10, 2);
