Question

我使用自定义元数据库创建了wordpress库，我的代码根据需要提供了正确的输出。但试图以标准方式制作它。

原始代码

$mytheme_gallery_one = get_post_meta( get_the_ID(), 'mytheme_image_one', true ); 
$mytheme_image_one_image = wp_get_attachment_image( $mytheme_gallery_one, 'large' ); 
$mytheme_image_one_url = wp_get_attachment_url( $mytheme_gallery_one );

$mytheme_gallery_two = get_post_meta( get_the_ID(), 'mytheme_image_two', true ); 
$mytheme_image_two_image = wp_get_attachment_image( $mytheme_gallery_two, 'large' ); 
$mytheme_image_two_url = wp_get_attachment_url( $mytheme_gallery_two );

$mytheme_gallery_three = get_post_meta( get_the_ID(), 'mytheme_image_three', true ); 
$mytheme_image_three_image = wp_get_attachment_image( $mytheme_gallery_three, 'large' ); 
$mytheme_image_three_url = wp_get_attachment_url( $mytheme_gallery_three );
?>
<figure class="fit-vid ed-youtube">
    <a href="<?php echo $mytheme_image_one_url; ?>" ><?php echo $mytheme_image_one_image; ?></a>
    <a href="<?php echo $mytheme_image_two_url; ?>" ><?php echo $mytheme_image_two_image; ?></a>
    <a href="<?php echo $mytheme_image_two_url; ?>" ><?php echo $mytheme_image_two_image; ?></a>
</fiture>

我正在尝试使用 foreach ：

缩短版本

foreach {
   my_theme_gallery;
   my_theme_image;
   my_theme_url
<figure class="fit-vid ed-youtube">
    <a href="<?php echo $mytheme_image_one_url; ?>" ><?php echo $mytheme_image_one_image; ?></a>
</fiture>
}

并需要输出上传的多张图片。

Answer 1

这是最简单的方法：

<figure class="fit-vid ed-youtube">
<?php

foreach ( array('one', 'two', 'three') as $theme )
{
    $mytheme_gallery = get_post_meta( get_the_ID(), 'mytheme_image_' . $theme, true );
    $mytheme_image = wp_get_attachment_image( $mytheme_gallery, 'large' );
    $mytheme_image_url = wp_get_attachment_url( $mytheme_gallery );

    echo '<a href="', $mytheme_image_url, '" >', $mytheme_image, '</a>';

}

?>
</figure>

Answer 2

<figure class="fit-vid ed-youtube">
<?php

**foreach ( array('one', 'two', 'three') as $theme )**
{
    $mytheme_gallery = get_post_meta( get_the_ID(), 'mytheme_image_' . $theme, true );
    $mytheme_image = wp_get_attachment_image( $mytheme_gallery, 'large' );
    $mytheme_image_url = wp_get_attachment_url( $mytheme_gallery );

    echo '<a href="', $mytheme_image_url, '" >', $mytheme_image, '</a>';

}

?>
</figure>

如果我们有超过20个阵列，那么

而不是使用多个arryas。有可能做出这样的事吗？ foreach（数组（＆＃39;一个＆＃39;，＆＃39;两个＆＃39;，＆＃39;三个＆＃39;，＆＃39;四个＆＃39;，＆＃39;五＆＃39; ;以及更多）作为$ theme） foreach（数组（＆＃39;一个+ 1＆＃39;）作为$ theme） 还是活着的？

我试图将这个正常的代码转换为foreach：
