我使用WP模板http://wpshower.com/themes/expositio/
构建了一个简单的网站该网站是:Mathiaswarnich.dk
没关系,但它没有显示alt文本,我无法想出php设置。这是图像的代码:
* The template for displaying image attachments
// Retrieve attachment metadata.
$metadata = wp_get_attachment_metadata();
get_header();
?>
<section id="primary" class="content-area image-attachment">
<div id="content" class="site-content" role="main">
<header class="entry-header">
<?php the_title('<h1 class="entry-title">', '</h1>'); ?>
<div class="entry-meta">
<div class="full-size-link">
<a href="<?php echo wp_get_attachment_url(); ?>"><?php echo $metadata['width']; ?> × <?php echo $metadata['height']; ?></a>
</div>
<div class="parent-post-link">
<a href="<?php echo get_permalink($post->post_parent); ?>" rel="gallery"><?php echo get_the_title($post->post_parent); ?></a>
</div>
</div>
</header><!--
--><article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<div class="entry-content">
<div class="entry-attachment">
<div class="attachment">
<?php expositio_the_attached_image(); ?>
</div><!-- .attachment -->
<?php if (has_excerpt()) : ?>
<div class="entry-caption">
<?php the_excerpt(); ?>
</div><!-- .entry-caption -->
<?php endif; ?>
</div><!-- .entry-attachment -->
<?php
the_content();
wp_link_pages(array(
'before' => '<div class="page-links"><span class="page-links-title">'.__('Pages:', 'expositio').'</span>',
'after' => '</div>',
'link_before' => '<span>',
'link_after' => '</span>',
));
?>

是的,我最近在我的摄影网站上也发现了同样的问题,也使用了WP Expositio主题。
Stender的答案中引入的变通方法不起作用,因为图库由自定义函数处理。
解决方案非常简单:
第1步:在主题目录中打开/inc/template-tags.php。
第2步:转到第87行并在此处检查代码:
function expositio_image_tag($thumbnail_id, $size = 'post-thumbnail') {
$meta = wp_get_attachment_metadata($thumbnail_id);
if ($meta === false || $meta === '') {
return sprintf(
'<img src="%s" width="%s" height="%s" alt="" />',
wpShower::defaultImage(),
wpShower::$default_image_width,
wpShower::$default_image_height
);
}
$src = wp_get_attachment_image_src($thumbnail_id, $size);
$size_available = isset($meta['sizes'][$size]);
return sprintf(
'<img src="%s" width="%s" height="%s" alt="" />',
$src[0],
$size_available ? $meta['sizes'][$size]['width'] : $meta['width'],
$size_available ? $meta['sizes'][$size]['height'] : $meta['height']
);
}
第3步:将以上代码块替换为:
function expositio_image_tag($thumbnail_id, $size = 'post-thumbnail') {
$meta = wp_get_attachment_metadata($thumbnail_id);
if ($meta === false || $meta === '') {
return sprintf(
'<img src="%s" width="%s" height="%s" alt="" />',
wpShower::defaultImage(),
wpShower::$default_image_width,
wpShower::$default_image_height
);
}
$alt = get_post_meta($thumbnail_id, '_wp_attachment_image_alt', true);
$src = wp_get_attachment_image_src($thumbnail_id, $size);
$size_available = isset($meta['sizes'][$size]);
return sprintf(
'<img src="%s" width="%s" height="%s" alt="%s" />',
$src[0],
$size_available ? $meta['sizes'][$size]['width'] : $meta['width'],
$size_available ? $meta['sizes'][$size]['height'] : $meta['height'],
$alt
);
}
第4步:保存/上传已编辑的文件。刷新网站。
基本上,我们在这里创建一个$ alt变量,它检索图像alt属性并将其添加到格式化的字符串值数组中。享受。

如果是精选图片 - 您可以更改
<?php expositio_the_attached_image(); ?>
到这个
//full is the size - If you have a size from the theme, use that instead.
//don't know how your theme works, but maybe 'expositio_attachment_size'
<?php the_post_thumbnail('full'); ?>
甚至是这个
<div class="attachment">
<?php expositio_the_attached_image(); ?>
</div><!-- .attachment -->
到此
<?php if ( has_post_thumbnail() ) : ?>
<div class="attachment">
<?php the_post_thumbnail('full'); ?>
</div><!-- .attachment -->
<?php endif; ?>
如果您缺少某些图像类,也可以向此函数添加属性: 像这样
<?php if ( has_post_thumbnail() ) : ?>
<div class="attachment">
<?php the_post_thumbnail('full', ['class' => 'img-responsive responsive--full', 'title' => 'Feature image']); ?>
</div><!-- .attachment -->
<?php endif; ?>
祝你好运,玩得开心!
