循环遍历ACF组的所有行而不指定行名称

时间：2018-05-23 10:00:01

标签： php wordpress advanced-custom-fields

在我的高级自定义字段中，我在一个组中有一个组。

内部群体中的字段是选择部分膳食。除了该组中的第一行外，格式将完全相同

enter image description here

我编写的代码输出食物名称和与每个食物名称相关的值（乘以另一个变量）。

除了输出它们之外，第5行和第6行都有if语句。它们仅显示另一个变量$ feeds_per_day是否与该餐号一样高。

这是代码......

        $protein_amount = round($zero_protein_feed / $protein_value * 10) * 10 ;
        $fat_amount = round($zero_fat_feed / $fat_value * 10) * 10 ;

            if ($feeds_per_day > 5){

        ?><tr><td>Meal 6</td><td><?php echo $protein_amount ?>g <?php echo $protein_label ?>, <?php echo $fat_amount ?>g <?php echo $fat_label ?></td></tr><?php } }

            }


endwhile;

        ?></table></div><?php
        endif;

...除了第一行之外，我重复了很多相同的代码。 有没有办法循环浏览所有字段并应用一种格式，如果该字段是＆＃39; on_waking＆＃39;如果不是，还有另一种格式？

尝试使用动态值循环进餐_：` 

    $mcount = 0; 
        while( have_rows('zero') ) : the_row(); $mcount++;?>

    <tr><td>Upon Waking</td><td><?php the_sub_field('upon_waking')?></td></tr>

    <?php
    if ( have_rows('meal_'.$mcount) ){ 
    while( have_rows('meal_'.$mcount) ) {
    the_row();

    $protein_object = (get_sub_field_object('protein_select'));                                 
    $protein_value = get_sub_field('protein_select');                                   
    $protein_label = ($protein_object['choices'][$protein_value]);

    $carb_object = (get_sub_field_object('carb_select'));                                   
    $carb_value = get_sub_field('carb_select');                                 
    $carb_label = ($carb_object['choices'][$carb_value]);

    $fat_object = (get_sub_field_object('fat_select'));                                 
    $fat_value = get_sub_field('fat_select');                                   
    $fat_label = ($fat_object['choices'][$fat_value]);

    $protein_amount = round($zero_protein_feed / $protein_value * 10) *10;
    $fat_amount = round($zero_fat_feed / $fat_value * 10) *10 ;

    ?><tr><td>Meal <?php echo$mcount; ?></td><td><?php echo $protein_amount ?>g <?php echo $protein_label ?>, <?php echo $fat_amount ?>g <?php echo $fat_label ?></td></tr><?php }  } ?>`

它可能有用!!

我的解决方案是使用for循环.. 

for ($i=1; $i<$feeds_per_day + 1; $i++) {
   if (have_rows('meal_'.$i)) {
     while (have_rows('meal_'.$i)) {

  the_row();
  //etc...

}}}

...或者，如果我的内部行没有顺序名称，我可以把它们全部放入一个数组中并像这样循环遍历...... 

$repeaters = array('zero', 'low', 'medium', 'high');
foreach ($repeaters as $repeater) {
if (have_rows($repeater)) {
while (have_rows($repeater)) {

  the_row();
  // etc...

    }
  }
}
