我无法使用高级自定义字段 WordPress 插件从中继器获取图像
I can't get images from a repeater using Advanced Custom Fields WordPress plugin
我附上了中继器的屏幕截图和图像高级自定义字段。
我已经为转发器图片块上传了三张图片。
现在,我可以获得那些船,但无法在屏幕上查看。我打开我的检查元素,我看到 while 循环正在执行并显示所有三艘船代码。
我的代码:
<?php
/*
Template Name: boatProduct
*/ ?>
<?php get_header(); ?>
<?php if( have_rows('boat_product_slider') ): while ( have_rows('boat_product_slider') ) : the_row(); ?>
<div class="product_boat" style="background: url('<?php the_sub_field('slider_image'); ?>'); background-size: cover;">
</div>
<?php endwhile; endif; ?>
</div>
<div id="charter" class="brokerage" style="background: linear-gradient(rgba(255,255,255,0.95), rgba(255,255,255,0.95)), url('<?php the_field('agys_icon'); ?>') no-repeat center 48%; background-size: 80%; background-attachment: fixed;">
<h3 style="margin-top:40px;">Specification</h3>
<p align="justify"><?php the_field('content'); ?></p>
</div>
<?php get_footer(); ?>
您需要对代码稍作改动,将 the_sub_field()
替换为 get_sub_field()
。
来自 get_sub_field()
文档:
This function will return a sub field value from a repeater field or flexible content field loop. This function is used within a have_rows()
loop.
the_sub_field()
函数将打印结果。这对您不起作用,因为您已将 slider_image
设置为 return "Image Object"。
来自文档:
This function will display a sub field value from a repeater field or flexible content field loop. This function is used within a have_rows()
loop.
This function is the same as echo get_sub_field('name');
.
编辑:"The Loop"
关于如何处理 WordPress 循环,您有两种选择:
选项 1
ACF函数需要在WordPress loop内部使用。例如(使用默认的 TwentySixteen WordPress 主题中的 page.php
:
<?php
// Start the loop.
while ( have_posts() ) : the_post();
// ACF functions should be added here, inside "the Loop"
// Include the page content template.
get_template_part( 'template-parts/content', 'page' );
// If comments are open or we have at least one comment, load up the comment template.
if ( comments_open() || get_comments_number() ) {
comments_template();
}
// End of the loop.
endwhile;
?>
选项 2
或者,您可以将 $post_id
参数添加到 have_rows()
以指定 ACF 字段应来自哪个 post/page:
$post_id
: Specific post ID where your value was entered. Defaults to current post ID (not required). This can also be options / taxonomies / users / etc
$post_id = 123; // This should be the ID of the post/page that contain the ACF fields
if( have_rows('boat_product_slider', $post_id) ):
// loop through the rows of data
while ( have_rows('boat_product_slider', $post_id) ) : the_row();
// ...
