Question

我有以下数组：

array (
  0 => 
  array (
    'new_service' => 
    array (
      0 => 
      array (
        'service_name' => 'wi-fi',
        'this_service_is_present' => true,
      ),
      1 => 
      array (
        'service_name' => 'Washing machine',
        'this_service_is_present' => false,
      ),
    ),
  ),
)

我需要显示该服务（如果存在），或者理想地同时显示两者，但要说该服务存在/不存在。

我只是尝试了一下以测试是否能够获取这些值然后进行计算，所以：

$repeater = get_field('servizi_casa');
foreach( $repeater as $row ) {
  echo $row[0][0][1];
}

或

$repeater = get_field('servizi_casa');
foreach( $repeater as $row ) {
  echo $row['service_name'];
}

和

$repeater = get_field('servizi_casa');
foreach( $repeater as $row ) {
  echo $row[0]['service_name'];
}

但是我做错了，因为我没有价值

Answer 1

如果您的输出为$repeater的值，则此代码应该起作用：

foreach ($repeater as $row) {
    foreach ($row['new_service'] as $service) {
        echo "{$service['service_name']} is " . ($service['this_service_is_present'] ? "" : "not ") . "present\n";
    }
}

输出：

wi-fi is present 
Washing machine is not present

<?php
$a = array (
  0 => 
  array (
    'new_service' => 
    array (
      0 => 
      array (
        'service_name' => 'wi-fi',
        'this_service_is_present' => true,
      ),
      1 => 
      array (
        'service_name' => 'Washing machine',
        'this_service_is_present' => false,
      ),
    ),
  ),
);


foreach($a[0]['new_service'] as $k) {
   if($k['this_service_is_present'])
     echo $k['service_name'] .'is present';
   } else {
      echo $k['service_name'] .'is Not present';
   }
}

如果为true，则显示php数组项
