我想在最近发布帖子的首页上做的是在今天发布的帖子的缩略图上添加一个小的上角徽章或带有“NEW”的功能区。下面是我的index.php，它控制首页布局：
<?php
/**
* The main template file.
*
* Used to display the homepage when home.php doesn't exist.
*/
?>
<?php
// Get options
$mts_options = get_option(MTS_THEME_NAME);
// Featured Section 1 settings ( slider is here) --------------------------------
$slider_enabled = ( $mts_options['mts_featured_slider'] === '1' ) ? true : false;
if ( empty($mts_options['mts_featured_slider_cat']) || !is_array($mts_options['mts_featured_slider_cat']) ) {
$mts_options['mts_featured_slider_cat'] = array('0');
}
$slider_cat = implode(",", $mts_options['mts_featured_slider_cat']);
// Featured Section settings --------------------------------------------------
$f2_title = $mts_options['mts_featured_section_2_title'];
if ( empty($mts_options['mts_featured_section_2_cat']) || !is_array($mts_options['mts_featured_section_2_cat']) ) {
$mts_options['mts_featured_section_2_cat'] = array('0');
}
$f2_cat= implode(",", $mts_options['mts_featured_section_2_cat']);
// Featured Section 3 settings --------------------------------------------------

我所拥有的是：检查日期并显示徽章（不包括CSS），但不确定在何处输入它：
<?php
$days_old = (current_time(timestamp) - get_the_time('U') - (get_settings('gmt_offset') *3600 ) ) / (60*60*24);
if ($days_old <=1) {
echo <div class="post-badge">NEW</div>;
}
?>
我想将其插入最新帖子部分。任何帮助将不胜感激：）
