实际上，我试着制作一个旋转木马，我想得到分类ID为4的所有页面的特征图像。下面的代码获取所有添加的页面，但不显示页面的标题。你们谁能告诉我代码里出了什么问题吗
<?php
$args = array(\'posts_per_page\' => -1,
\'offset\' => 1,
\'category\' => 4,
\'numberposts\' => -1
);
$pages = get_pages($args);
$i = 1;
foreach ($pages as $page) {
setup_postdata($page);
if ($i == 1) {
?>
<div class="carousel-item active"
style="background-image: url(\'<?php echo get_bloginfo(\'template_url\'); ?>/img/intro-carousel/1.jpg\');">
<div class="carousel-container">
<div class="carousel-content">
<?php $image = wp_get_attachment_image_src(get_post_thumbnail_id($page->ID), \'optional-size\'); ?>
<h2><?php echo $page->post_title; ?></h2>
<p>
<?php echo strip_tags(get_the_excerpt()); ?>
<span>Convert Visitors Into Customers And Generate More Sales</span>
</p>
<a href="#about" class="btn-get-started scrollto"><img
src="<?php echo $image[0]; ?>" alt="arrow"/></a>
</div>
</div>
</div>
<?php } else { ?>
<div class="carousel-item"
style="background-image: url(\'<?php echo get_bloginfo(\'template_url\'); ?>/img/intro-carousel/1.jpg\');">
<div class="carousel-container">
<div class="carousel-content">
<?php $image = wp_get_attachment_image_src(get_post_thumbnail_id($page->ID), \'optional-size\'); ?>
<h2><?php echo $page->post_title; ?></h2>
<p>
<?php echo strip_tags(get_the_excerpt()); ?>
<span>Convert Visitors Into Customers And Generate More Sales</span>
</p>
<a href="#about" class="btn-get-started scrollto"><img
src="<?php echo $image[0]; ?>" alt="arrow"/></a>
</div>
</div>
</div>
<?php }
$i++;
}
?>

Use this code ,
<?php
$args = array(
\'posts_per_page\' => -1,
\'offset\' => 1,
\'category\' => 4,
\'numberposts\' => -1
);
$pages = get_pages($args);
$i = 1;
foreach ($pages as $page) {
if ($i == 1) { ?>
<div class="carousel-item active" style="background-image: url(\'<?php echo get_bloginfo(\'template_url\'); ?>/img/intro-carousel/1.jpg\');">
<div class="carousel-container">
<div class="carousel-content">
<?php $image = wp_get_attachment_image_src(get_post_thumbnail_id($page->ID), \'optional-size\'); ?>
<h2><?php echo $page->post_title; ?></h2>
<p>
<?php echo strip_tags(get_the_excerpt()); ?>
<span>Convert Visitors Into Customers And Generate More Sales</span>
</p>
<a href="#about" class="btn-get-started scrollto">
<img src="<?php echo $image[0]; ?>" alt="arrow"/>
</a>
</div>
</div>
</div>
<?php } else { ?>
<div class="carousel-item" style="background-image: url(\'<?php echo get_bloginfo(\'template_url\'); ?>/img/intro-carousel/1.jpg\');">
<div class="carousel-container">
<div class="carousel-content">
<?php $image = wp_get_attachment_image_src(get_post_thumbnail_id($page->ID), \'optional-size\'); ?>
<h2><?php echo $page->post_title; ?></h2>
<p>
<?php echo strip_tags(get_the_excerpt()); ?>
<span>Convert Visitors Into Customers And Generate More Sales</span>
</p>
<a href="#about" class="btn-get-started scrollto">
<img src="<?php echo $image[0]; ?>" alt="arrow"/>
</a>
</div>
</div>
</div>
<?php }
$i++;
}
wp_reset_query();
?>
