外部变量 foreach 循环 php

我遇到了一个问题。

在 Wordpress 上，我定义了一个 foreach 循环，从附加的图像中获取一些信息，如标题、描述等......

在这个循环之外，我想调用各种变量的结果。如何在循环之外获得$attachment_description、$attachment_caption和$attachment_title？

感谢您的帮助。代码下方：

if ( $attachments ) : 
echo $before;
    foreach( $attachments as $ID ){
        $attachment = get_post($ID);
        $attachment_description = $attachment->post_content; //Display description
        $attachment_caption = $attachment->post_excerpt; //Display caption
        $attachment_title = $attachment->post_title; //Display title
        //IF : Affichage sur certaines images
        //if($attachment_description != ''){
        //echo '<div class="item">' . wp_get_attachment_image( $attachment->ID, 'portfolioslider' ) . '<div class="captionportfolio"><h1 class="titrecaption">' . $attachment_title . '</h1>' . $attachment_description . '</div></div>';
        //}// else {
        echo '<div class="item">' . wp_get_attachment_image( $attachment->ID, 'portfolioslider' ) . '</div>';
        //}
    }
echo $after;
endif;

似乎没有任何东西有效，这是第一个带有循环的文件：

<?php 
/**
 * Make sure we can access post data easily.
 */
global $post;
/**
 * Setup variables needed for the gallery
 */
$attachments = get_post_meta( $post->ID, '_ebor_portfolio_gallery_list', true );
$type = get_post_meta( $post->ID, '_ebor_gallery_format', true );
$before = '<div class="owl-carousel portfolio-slider custom-controls">';
$after = '</div>';
if( $type == 'carousel' ){
$before = '<div class="carousel-gallery-wrapper"><div class="carousel-gallery custom-controls">';
$after = '</div></div>';
}
/**
 * If we found items, output the gallery.
  * $before and $after change depending on the gallery chosen.
 */
if ( $attachments ) : 
echo $before;
$arrayInformation = array();
    foreach( $attachments as $ID ){
        $attachment = get_post($ID);
        $attachment_description = $attachment->post_content; //Afficher la description
        $attachment_caption = $attachment->post_excerpt; //Afficher le caption
        $attachment_title = $attachment->post_title; //Afficher le titre
        $arrayInformation[$ID] = array("title" =>$attachment_title, "caption" =>$attachment_caption, "description" =>$attachment_description);
        //IF : Affichage sur certaines images
        //if($attachment_description != ''){
        //echo '<div class="item">' . wp_get_attachment_image( $attachment->ID, 'portfolioslider' ) . '<div class="captionportfolio"><h1 class="titrecaption">' . $attachment_title . '</h1>' . $attachment_description . '</div></div>';
        //}// else {
        echo '<div class="item">' . wp_get_attachment_image( $attachment->ID, 'portfolioslider' ) . '</div>';
        //}
    }
echo $after;
endif;

我想将变量的内容调用到这个文件中：

<div class="container inner">
<?php get_template_part('postformats/format', get_post_format()); ?>
<div class="divide30"></div>
<?php 
global $post;
$titrecat = get_the_title();
if( has_term( 'creation', 'portfolio-category' ) ) {
echo '<p><span class="portfolio-title">Création - </span>' . $titrecat . '</p>'; 
print $arrayInformation[$ID]["description"];
}
else if( has_term( 'realisation', 'portfolio-category' ) ) {
echo '<p><span class="portfolio-title">Réalisations - </span>' . $titrecat . '</p>';
print $arrayInformation[$ID]["description"]; 
}
else if( has_term( 'inspiration', 'portfolio-category' ) ) {
echo '<p><span class="portfolio-title">Inspiration - </span>' . $titrecat . '</p>'; 
print $arrayInformation[$ID]["description"];
}
?>  
</div>

get_template_part（'postformat/format'， get_post_format（））;当然，请参考第一个文件

我无法将$ID号放入第二个文件中，原因是可变的，感谢您的宝贵帮助:)
