问题描述：

My current theme supports Gallery Post Formats. The Gallery format takes all images from the gallery and displays them in a slideshow. I want to be able to add the caption and photo credit line to the bottom of each image as it changes for the information to change along with it.

The current gallery format template looks like this:

 <?php if ( has_post_format( \'gallery\' ) ) : ?>
<div class=\"gallery-post-format\">
<?php
$galleries = get_post_gallery_images( $post );
$output = \'<ul class=\"gallery-images\">\';
foreach ($galleries as $gallery) {
$output .= \'<li>\' . \'<img src=\"\'. $gallery . \'\">\' . \'</li>\';
}
$output .= \'</ul>\';
echo $output;
?>
</div>
<?php endif; ?>

I am wanting to add the following code to display the captions and photo credit line to each image.

    <div>
<?php 
$photographer_name = get_post_meta(get_post_thumbnail_id(), \'be_photographer_name\', true);
$photographer_url = get_post_meta(get_post_thumbnail_id(), \'be_photographer_url\', true);
if ( $photographer_name ) : ?>
<div id=\"tgg_credit_line\" class=\"tgg-photo-credit\" align=\"right\">
📷 Image Credit /
<?php if ( $photographer_url ) : ?> 
<a href=\"<?php echo $photographer_url ?>\">
<?php endif; ?>
<?php echo $photographer_name ?>
<?php if ( $photographer_url ) : ?> 
</a>
<?php endif; ?>
</div>
<?php endif; ?>
</div>
<div id=\"tgg_image_caption\" class=\"tgg-image-caption\" align=\"left\">
<?php echo get_post(get_post_thumbnail_id())->post_excerpt; ?>
</div>
</div>

How can I do this?

我当前的主题支持Gallery Post格式。 图库格式从图库中获取所有图像并以幻灯片形式显示。 我希望能够将标题和照片信用额度添加到每个图像的底部，因为它会随着信息的变化而变化。</ p>

当前图库格式模板如下所示 ：</ p>

 ＆lt;？php if（has_post_format（\'gallery\'））：？＆gt; 
＆lt; div class =“gallery-post-format”＆gt;  
＆lt;？php 
$ galleries = get_post_gallery_images（$ post）; 
$ output =\'＆lt; ul class =“gallery-images”＆gt;\'; 
foreach（$ galleries as $ gallery）{  
$ output。=\'＆lt; li＆gt;\'  。  \'＆lt; img src =“\'。$ gallery。\'”＆gt;\'  。  \'＆lt; / li＆gt;\'; 
} 
$ output。=\'＆lt; / ul＆gt;\'; 
echo $ output; 
？＆gt; 
＆lt; / div＆gt; 
＆lt;  ？php endif;  ？＆gt; 
</ code> </ pre> 
我想添加以下代码，以显示每张图片的标题和照片信用额度。</ p> 
 ＆lt; div＆gt; 
＆lt;？php 
$ photographer_name = get_post_meta（get_post_thumbnail_id（），\'be_photographer_name\'，true）; 
$ photographer_url = get_post_meta（get_post_thumbnail_id（），\'be_photographer_url\'，true）;  
if（$ photographer_name）：？＆gt; 
＆lt; div id =“tgg_credit_line”class =“tgg-photo-credit”align =“right”＆gt; 
＆amp;＃x1F4F7;  Image Credit / 
＆lt;？php if（$ photographer_url）:?＆gt;  
＆lt; a href =“＆lt;？php echo $ photographer_url？＆gt;”＆gt; 
＆lt;？php endif;  ？＆gt; 
＆lt;？php echo $ photographer_name？＆gt; 
＆lt;？php if（$ photographer_url）:?＆gt;  
＆lt; / a＆gt; 
＆lt;？php endif;  ？＆gt; 
＆lt; / div＆gt; 
＆lt;？php endif;  ？＆gt; 
＆lt; / div＆gt; 
＆lt; div id =“tgg_image_caption”class =“tgg-image-caption”align =“left”＆gt; 
＆lt;？php echo get_post（get_post_thumbnail_id（）） - ＆gt;  post_excerpt;  ？＆gt; 
＆lt; / div＆gt; 
＆lt; / div＆gt; 
</ code> </ pre> 
我该怎么做？</ p> 
</ div>

How about this:
<?php if ( has_post_format( \'gallery\' ) ) : ?>
<div class=\\\"gallery-post-format\\\">
<?php
$gallery = get_post_gallery( $post, false );
$att_ids = wp_parse_id_list( $gallery[\'ids\'] );
$output = \'<ul class=\\\"gallery-images\\\">\';
for ( $i = 0; $i < count( $gallery[\'src\'] ); $i++ ) {
$att_id = $att_ids[ $i ];
$photographer_name = get_post_meta( $att_id, \'be_photographer_name\', true );
$photographer_url = get_post_meta( $att_id, \'be_photographer_url\', true );
$image = sprintf( \'<img src=\\\"%s\\\" />\',
esc_url( $gallery[\'src\'][ $i ] ) );
$caption = \'<div>\';
if ( $photographer_name ) {
$caption .= \'<div class=\\\"tgg-photo-credit\\\" align=\\\"right\\\">\';
$caption .= \'📷 Image Credit /\';
if ( $photographer_url ) {
$caption .= sprintf( \'<a href=\\\"%s\\\">%s</a>\',
esc_url( $photographer_url ), esc_html( $photographer_name ) );
} else {
$caption .= esc_html( $photographer_name );
}
$caption .= \'</div><!-- .tgg-photo-credit -->\';
}
$caption .= \'</div>\';
$excerpt = get_post_field( \'post_excerpt\', $att_id );
if ( $excerpt ) {
$caption .= /* wrapped */
\'<div class=\\\"tgg-image-caption\\\" align=\\\"left\\\">\' .
$excerpt .
\'</div><!-- .tgg-image-caption -->\';
}
$output .= \'<li>\' . $image . $caption . \'</li>\';
}
$output .= \'</ul><!-- .gallery-images -->\';
echo $output;
?>
</div><!-- gallery-post-format -->
<?php endif; ?>
Or another version, which directly echoes the output instead of saving it in a variable (i.e. $output):
<?php if ( has_post_format( \'gallery\' ) ) : ?>
<div class=\\\"gallery-post-format\\\">
<?php
$gallery = get_post_gallery( $post, false );
$att_ids = wp_parse_id_list( $gallery[\'ids\'] );
?>
<ul class=\\\"gallery-images\\\">
<?php for ( $i = 0; $i < count( $gallery[\'src\'] ); $i++ ) : ?>
<li>
<?php
$att_id = $att_ids[ $i ];
$photographer_name = get_post_meta( $att_id, \'be_photographer_name\', true );
$photographer_url = get_post_meta( $att_id, \'be_photographer_url\', true );
$excerpt = get_post_field( \'post_excerpt\', $att_id );
?>
<img src=\\\"<?php echo esc_url( $gallery[\'src\'][ $i ] ); ?>\\\" />
<div>
<?php if ( $photographer_name ) : ?>
<div class=\\\"tgg-photo-credit\\\" align=\\\"right\\\">
📷 Image Credit /
<?php if ( $photographer_url ) : ?>
<a href=\\\"<?php echo esc_url( $photographer_url ); ?>\\\"><?php echo esc_html( $photographer_name ); ?></a>
<?php else : ?>
<?php echo esc_html( $photographer_name ); ?>
<?php endif; // end $photographer_url ?>
</div><!-- .tgg-photo-credit -->
<?php endif; // end $photographer_name ?>
</div>
<?php if ( $excerpt ) : ?>
<div class=\\\"tgg-image-caption\\\" align=\\\"left\\\">
<?php echo $excerpt; ?>
</div><!-- .tgg-image-caption -->
<?php endif; // end $excerpt ?>
</li>
<?php endfor; // end gallery loop ?>
</ul><!-- .gallery-images -->
</div><!-- .gallery-post-format -->
<?php endif; ?>
