ACF 如何更新查询中的单个字段

Question

我需要根据以下代码仅在满足条件（购买值和使用值相等）时更新特定 post 的无线电字段。相反，这会更新所有 post 上的无线电选择。需要帮助解决这个问题。

如果我可以使用任何其他替代方法来满足此要求，也请提及。

<?php

function expired() {
  echo "Expired";
}

function rto_deactivation() {
  $post_id = false;
  update_field('field_59ba2159ddd3b', 'Deactive', $post_id);
}

// Issue on function rto_deactivation(), when calls all RTOs get deactivated

$i=1;
$args = array(
  'numberposts' => -1,
  'post_type'   => 'rto_providers',
  'meta_key'    => 'package',
  'meta_value'  => 'Casual RTO'
);

$the_query = new WP_Query( $args );

?>
<?php if( $the_query->have_posts() ): ?>

  <div class="table-responsive">
  <table class="table">
    <thead>
      <tr>
        <th>#</th>
        <th>RTO Name</th>
        <th>Email Address</th>
        <th>Purchased</th>
        <th>Used</th>
        <th>Status</th>
      </tr>
    </thead>
    <tbody>

  <?php 
  while( $the_query->have_posts() ) : $the_query->the_post(); 
  $email_id = get_field( 'email_address', $post_id );
  $number_of_enquiries = get_field( 'number_of_enquiries', $post_id );
  $account_activation = get_field( 'account_activation', $post_id );
  ?>
    <tr>
      <td><?php echo $i++; ?></td>
      <td><?php the_title(); ?></td>
      <td><?php echo $email_id; ?></td>
      <td><?php echo $number_of_enquiries; ?></td>

      <?php
      $used = $wpdb->get_var(" SELECT COUNT(*) FROM table_name WHERE form_name = 'Course Enquiry' AND field_value = '$email_id' ");
      ?>

      <td><?php echo $used; ?></td>
      <td class="<?php if ($number_of_enquiries == $used) echo 'red'; ?>"><?php if ($number_of_enquiries == $used) expired(); rto_deactivation(); ?></td>
    </tr>
  <?php endwhile; ?>
  </tbody>
  </table>
  </div>
<?php endif; ?>

<?php wp_reset_query(); ?>

Answer 1

您没有在以下代码的 if 条件中调用 rto_deactivation：

<td class="<?php if ($number_of_enquiries == $used) echo 'red'; ?>">
   <?php if ($number_of_enquiries == $used) expired(); rto_deactivation(); ?>
</td>

当满足 if 条件时，您没有任何要调用的行：

if ($number_of_enquiries == $used) expired(); rto_deactivation();

...所以 expired(); 只有在满足条件时才会被调用，但是 rto_deactivation 总是会被执行。

只需将 'if' 更改为：

if ($number_of_enquiries == $used) { expired(); rto_deactivation(); }
