可变前驱循环php
可变前驱循环php
提问于 2014-11-17 10:21:20
我有麻烦了。
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。如何将$attachment_description、$attachment_caption和$attachment_title置于循环之外？
谢谢你的帮助。守则如下：
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;似乎没有什么是可行的，这是循环的第一个文件：
<?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('postformats/format'，get_post_format())；当然，请参阅第一个文件
我无法将$ID编号放入第二个文件中，原因是可变的，谢谢您宝贵的帮助:)

您可以创建一个数组，其中索引是您的$ID，值是一个包含您想要的信息的数组。
$arrayInformation = array();
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
$arrayInformation[$ID] = array("title" =>$attachment_title, "caption" =>$attachment_caption, "description" =>$attachment_description)
}现在您可以获得值(例如，如果您的ID是1)
print $arrayInformation[1]["title"];
print $arrayInformation[1]["caption"];
print $arrayInformation[1]["description"];页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
