我在我的functions.php页面中编写了一个函数,用于在某些页面上显示的库。它显示在自定义模板上,但现在我需要它在index.php上显示以下是我的functions.php文件中的代码:
function min_get_page_gallery( $echo = true) {
global $post;
$show_gallery = get_post_meta($post->ID, 'min_gallery-show', true);
if ( empty($show_gallery) ) {
return;
}
$gallery = get_post_meta($post->ID, 'min_image_advanced', false);
ob_start();
?>
<div class="gallery" id="gallery-<?php echo $post->ID; ?>">
<button class="gallery-move-left"><i class="fa fa-arrow-circle-left" aria-hidden="true"></i></button>
<div class="image_container clearfix">
<?php
$count = count($gallery);
$num = ceil($count / 3);
//$width_container = $num * 100;
//$width_row = 100 / $num;
//echo '<div class="gallery_inner" style="width:' . $width_container . '%;">';
echo '<div class="gallery_inner">';
for ( $i = 0; $i < $count; $i++) {
if ( $i % 3 == 0 ) {
//echo '<div class="row" style="width: ' . $width_row . '%;">';
echo '<div class="row'. (0 == $i ? ' active': ' inactive') .'">';
}
echo '<div class="col-sm-4 img_container' . (0 == $i ? ' active': ' inactive') . '">';
echo wp_get_attachment_image($gallery[$i], 'thumb-gallery');
echo '</div>';
if ( $i % 3 == 2 || ($i+1) == $count) {
echo '</div>';
}
}
echo '</div>';
?>
</div>
<button class="gallery-move-right"><i class="fa fa-arrow-circle-right" aria-hidden="true"></i></button>
</div>
<?php
$return = ob_get_contents();
ob_end_clean();
if ( $echo ) {
echo $return;
} else {
return $return;
}
}
该代码就像一个魅力。这里我称之为min_get_page_gallery();在awards.php中,它完美无瑕地运作:
<?php
/* Template Name: Awards Page Template */
get_header(); ?>
<div class="container" id="block-no-sidebar">
<h1><?php the_title(); ?></h1>
<div id="award-list">
<?php echo min_get_awards(); ?>
</div>
<div class="row">
<?php min_get_page_gallery(); ?>
</div>
<?php min_get_page_tabs(); ?>
</div>
<?php get_footer(); ?>
最后,我尝试添加min_get_page_gallery()的相同函数调用;在我的index.php文件中,如下所示:
<?php
// Silence is golden.
if ( ! defined ( 'ABSPATH' ) ) {
exit;
}
?>
<?php get_header(); ?>
<style class="take-to-head">
#block-main-content-with-sidebar { background: #ffffff; }
</style>
<div class="container" id="block-main-content-with-sidebar">
<div class="row">
<div class="col-sm-8">
<?php
if ( have_posts() ) : while ( have_posts() ) : the_post();
l('block-' . get_post_type());
endwhile; else:
l('block-none' );
endif;
?>
</div>
<div class="col-sm-4">
<?php l('block-sidebar'); ?>
</div>
</div>
<div class="row">
<?php min_get_page_gallery(); ?>
</div>
</div>
有什么我想念的吗?

尝试更详细地描述您的index.php
有什么问题?加载input.php
或空白页时是否有输出?
是否正确定义ABSPATH
?如果没有,您的脚本将在开头退出。
要更加具体地了解流程,请尝试在那里写一些echo
E.g。
<div class="row">
<?php echo "Before calling min_get_page_gallery()" ?>
<?php min_get_page_gallery(); ?>
<?php echo "After calling min_get_page_gallery()" ?>
</div>
然后看看,如果在调用所需函数之前和之后可以看到来自echo的消息。

好的,所以我不得不做一些调整以获得在functions.php中显示的元数据我添加了这些行:
$pagemain = is_page();
然后:
if ( $pagemain == is_page( 35393 ) ) {
$meta[] = array(
'id' => 'imageupload',
'post_types' => array( 'page'),
'context' => 'normal',
'priority' => 'high',
'title' => __( 'Image Gallery', 'min' ),
'fields' => array(
array(
'name' => __( 'Show', 'min' ),
'id' => "{$prefix}_gallery-show",
'desc' => __( '', 'meta-box' ),
'type' => 'checkbox',
'clone' => false,
),
array(
'id' => "{$prefix}_image_advanced",
'name' => __( 'Image Advanced', 'min' ),
'type' => 'image_advanced',
// Delete image from Media Library when remove it from post meta?
// Note: it might affect other posts if you use same image for multiple posts
'force_delete' => false,
// Maximum image uploads
//'max_file_uploads' => 2,
),
),
);
}
