下面的代码位于functions.php文件中:
while ( have_rows('origin-repiter') ): the_row();
$origin = get_sub_field('origin-rep');
endwhile;
while ( have_rows('destination-repiter') ): the_row();
$destination = get_sub_field('destination-rep');
endwhile;
这里是origin-repiter/destination repiter中继器字段名和origin-rep/destination-rep是中继器字段，如果你想的话，可以行。
我的问题是，在我的WP网站的前端，ACF只显示从后端中继器字段的最后输入。
的例子:
For ORIGIN我输入:
伦敦，巴黎，莫斯科(三行)相同的目的地，但反向(莫斯科，巴黎，伦敦)。
但是前端ACF只显示最后一个条目
原产地:MOSCOW &目的地:伦敦
这是一个来自functions.php的代码，它为这两个字段/片段在前端呈现PHP/HTML:
$output .= '<div class="post_offer"><div class="offer-header"><div class="offer-pr"><div class="offer-pr-t"> from</div> <div class="offer-pr-v"><div class=""><div class="offer-pr-c">'.$fcurrency_icon .'</div><span class="price" style="font-size:30px;">'.$fprice.'</span></div></div></div> <h2 class="offer-tl editor-paragraph-tags">'.$ftitle.'</h2></div><div class="offer-rt-rd"><div class="offer-rt-rd-o"><div class="offer-rt-rd-lb">Origin</div><div class="offer-rt-rd-lo">'.$origin.'</div></div><div class="offer-rt-rd-d"><div class="offer-rt-rd-lb">Destination</div><div class="offer-rt-rd-lo">'.$destination .'</div></div><div class="offer-rt-rd-ico"></div></div>';
感谢任何帮助!!

您的第一个代码示例没有多大意义，因为您不断地覆盖$origin和$destination的值。此外，如果您想要耦合源值和目标值，您应该按照以下方式设置ACF字段:1个中继器和2个中继器子字段用于origin和destination
要循环遍历前端的中继器值，使用如下结构:
<?php
// check if the repeater field has rows of data
if( have_rows('your_repeater_name') ): /* your_repeater_name corresponds to the name of your repeater field */
// loop through the rows of data
while ( have_rows('your_repeater_name') ) : the_row();
// display the sub field (the function the_sub_field echos the values directly)
the_sub_field('origin'); /* sub-field with name "origin" */
the_sub_field('destination'); /* sub-field with name "destination" */
// or save the sub fields in a variable
$origin = get_sub_field('origin');
$destination= get_sub_field('destination');
// and then echo them
// you need to output them **INSIDE** the while loop
echo $origin;
echo $destination;
endwhile;
else :
// no rows found
endif;
?>
应用于您的场景，假设您有一个functions.php和一个页面模板:
将此添加到functions.php:
注意，您必须检查acf-field-names是否与代码匹配。示例中的中继器字段名为"your_repeater_name"。
function print_origin_dest(){
// check if the repeater field has rows of data
if( have_rows('your_repeater_name') ):
// loop through the rows of data
while ( have_rows('your_repeater_name') ) : the_row();
// get the acf values
$origin = get_sub_field('origin');
$destination= get_sub_field('destination');
// add the title and icon html here (you have not defined them in your question)
$ftitle = 'Your title';
$fcurrency_icon = '';
// render the content
$output = '<div class="post_offer"><div class="offer-header"><div class="offer-pr"><div class="offer-pr-t"> from</div> <div class="offer-pr-v"><div class=""><div class="offer-pr-c">'.$fcurrency_icon .'</div><span class="price" style="font-size:30px;">'.$fprice.'</span></div></div></div> <h2 class="offer-tl editor-paragraph-tags">'.$ftitle.'</h2></div><div class="offer-rt-rd"><div class="offer-rt-rd-o"><div class="offer-rt-rd-lb">Origin</div><div class="offer-rt-rd-lo">'.$origin.'</div></div><div class="offer-rt-rd-d"><div class="offer-rt-rd-lb">Destination</div><div class="offer-rt-rd-lo">'.$destination .'</div></div><div class="offer-rt-rd-ico"></div></div>';
echo $output;
endwhile;
else :
// no rows found
endif;
}
然后在页面模板中调用函数:
<?php print_origin_dest(); ?>
