我正在尝试在同一页面上添加两次短代码，但问题是第二个短代码没有显示任何内容。我认为这可能是查询的一些问题，但我不确定这一点。这是我的短代码：
<?php
defined( 'ABSPATH' ) or die( 'No script kiddies please!' );
if ( ! is_admin() ) {
require_once( ABSPATH . 'wp-admin/includes/post.php' );
}
function eleva_shortcode($atts = array()){
$atts=shortcode_atts( array(
'display' => '3',
'limit' => '5',
'length' => '15',
'title' => "",
'category' => ""
), $atts ) ;
$display = $atts['display'] ;
$pars = intval($display);
$col = 0;
if($pars==1 || $pars==2 || $pars==3 || $pars==4 || $pars==6){
$col = 12 / $pars;
}
else{
$pars =3;
$col = 12 / $pars;
}
$limit = $atts['limit'];
$pars_limit = intval($limit);
$length = $atts['length'];
$pars_length = intval($length);
$title = $atts['title'];
$id = post_exists($title);
$taxonomy = $atts['category'];
?>

循环结束后，您需要重置发布数据。
/* Restore original Post Data */ `wp_reset_postdata();`

我的猜测是问题正在发生，因为有两个具有相同ID属性的HTML元素
尝试下面的代码，它使用PHP的uniqid函数为每个滑块元素创建唯一的ID
<?php
defined( 'ABSPATH' ) or die( 'No script kiddies please!' );
if ( ! is_admin() ) {
require_once( ABSPATH . 'wp-admin/includes/post.php' );
}
function eleva_shortcode($atts = array()){
$atts=shortcode_atts( array(
'display' => '3',
'limit' => '5',
'length' => '15',
'title' => "",
'category' => ""
), $atts ) ;
$el_id = uniqid();
$display = $atts['display'] ;
$pars = intval($display);
$col = 0;
if($pars==1 || $pars==2 || $pars==3 || $pars==4 || $pars==6){
$col = 12 / $pars;
}
else{
$pars =3;
$col = 12 / $pars;
}
$limit = $atts['limit'];
$pars_limit = intval($limit);
$length = $atts['length'];
$pars_length = intval($length);
$title = $atts['title'];
$id = post_exists($title);
$taxonomy = $atts['category'];
ob_start();
?>
<script>

tQ(document).ready(function(){
