我正在构建一个自定义的post类型，在生成ID:s时遇到了一些困难。post类的思想是生成一个具有ID和post标题的表。我想知道是否有可能根据类中的帖子数量生成唯一的ID，从1开始。我对post类或类型的计划是，它将被用作常见问题解答，其中标题将启动一个带有答案的boostrap模式。

以下是相关代码：

function cptModal_frontend($atts){
$id = rand(0, 999); // use a random ID so that the CSS IDs work with multiple on one page
$args = array( \'post_type\' => \'cptModal\', \'orderby\' => \'menu_order\', \'order\' => \'ASC\');
$loop = new WP_Query( $args );
$modals = array();
while ( $loop->have_posts() ) {
    $loop->the_post();
    if ( \'\' != get_the_title() ) {
        $title = get_the_title( get_the_ID());
        $content = get_the_excerpt();
        $modals[] = array(\'title\' => $title, \'content\' => $content);
    }
}
if(count($modals) > 0){
    ob_start();
    ?>
    <!--Table start-->

    <table class="table table-hover table-bordered">
    <thead>
          <tr>
            <th>#</th>
            <th>Fråga:</th>
          </tr>
    </thead>
    <tbody>
        <?php foreach ($modals as $key => $title) { ?>
        <tr>
          <td><?php echo $id;?></td>
          <td><a href="#cptmodal_<?php echo $id; ?>" data-toggle="modal"><?php echo $title[\'title\'];?></a></td>
        </tr>
