ACF - 中继器仅显示最后输入的行，而不是帖子中的所有行

Question

我的functions.php文件中有这段代码：

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 转发器字段名称，origin-rep/destination-rep 是转发器字段，如果需要，行。

我的问题是，在我的 WP 站点的前端，ACF 仅显示来自后端的转发器字段的最后输入。

例子：

对于我输入的 ORIGIN：

伦敦、巴黎、莫斯科（三行）与 DESTINATION 相同，但相反（莫斯科、巴黎、伦敦）。

但是在前端 ACF 上只显示最后一个条目

出发地：莫斯科和目的地：伦敦

这是来自 functions.php 的代码，它在前端为这两个字段/sn-ps 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>';

Answer 1

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，如果要耦合起点和终点值，则应按如下方式设置 ACF 字段：1 个中继器和 2 个中继器子字段用于起点和终点

要在前端循环遍历转发器值，请使用如下结构：

<?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;

?>

应用于你的场景，假设你有一个functions.php和一个页面模板：

将此添加到您的 functions.php：

注意，您必须检查 acf-field-names 是否与代码匹配。示例中的转发器字段称为“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;
}

然后在你的页面模板中，调用函数：

<?php print_origin_dest(); ?>
