Php 插入到另一个数组中的条件数组输出

我有以下代码创建一个电子邮件活动，并将其发送到mailchimp中的特定部分

    $data = array("recipients" => array(
        "list_id" => "$listId",
        "segment_opts" => array(
            'match' => 'any', // or 'all' or 'none'
            'conditions' => array (
                array(
                    'condition_type' => 'Interests', // note capital I
                    'field' => 'interests-0a6fa2c02e', // ID of interest category
                    'op' => 'interestcontains', // or interestcontainsall, interestcontainsnone
                    'value' => array (
                        '11111111',  // ID of interest in that category
                        '22222222', // ID of another interest in that category
                        '33333333',
                        '44444444',
                        '55555555'
                    )
                 )
            
              )
           )
        ),
        "type" => "regular",
        "status" => "paused",
        //"schedule_time" => $form_data['post_date'],
        "schedule_time" => "2020-09-15T15:00:00+00:00",
        "timewarp" => false,
        "batch_delivery" => array(
            "batch_delay" => 0,
            "batch_count" => 0
        ),
        "settings"  => array(
            "subject_line"  => $form_data['lbu_subject'],
            "title"         => $form_data['post_title'],
            "from_name"     => $form_data['lbu_from'],
            "reply_to"      => get_option('lubuvna-company-email'),
            "template_id"   => 999999,
        )
    );

我可以从下面的表格中获得动态值，它工作得很好：

    if ( $form_data['lbu_to'] == 'multilists' && $form_data['lbu_multilistsvalue'] !== '' ){

        // get the comma separated values from 'lbu_multilistsvalue' input.
        $commaValues = $form_data['lbu_multilistsvalue'];
        $lubuvnaCommas = explode(',', $commaValues);

        $segment_opts = array(
            "segment_opts" => array(
                'match' => 'any', // or 'all' or 'none'
                'conditions' => array (
                    array(
                        'condition_type' => 'Interests', // note capital I
                        'field' => 'interests-0a6fa2c02e', // ID of interest category
                        'op' => 'interestcontains', // or interestcontainsall, interestcontainsnone
                        /*'value' => array (
                            '11111111',  // ID of interest in that category
                            '22222222', // ID of another interest in that category
                            '33333333',
                            '44444444',
                            '55555555'
                        )*/
                        'value' => $lubuvnaCommas // array from values
                    )
                
                  )
                )
        );

    } else {

      $segment_opts = '';

    }

最终结构应如下所示，但这不起作用：

    $data = array("recipients" => array(
           "list_id" => "$listId",
           $segment_opts,
        ),
        
        "type" => "regular",
        "status" => "paused",
        //"schedule_time" => $form_data['post_date'],
        "schedule_time" => "2020-09-15T15:00:00+00:00",
        "timewarp" => false,
        "batch_delivery" => array(
            "batch_delay" => 0,
            "batch_count" => 0
        ),
        "settings"  => array(
            "subject_line"  => $form_data['lbu_subject'],
            "title"         => $form_data['post_title'],
            "from_name"     => $form_data['lbu_from'],
            "reply_to"      => get_option('lubuvna-company-email'),
            "template_id"   => 99999,
        )
    );

我需要检查“lbu_multilistsvalue”是否为空，然后避免在最终结构中输出$segment_opts变量。我总是被困在这样的数组中，需要一些有条件的数据。

使用

array\u merge（）

组合两个数组

$data = array("recipients" => array_merge(array("list_id" => "$listId"), $segment_opts),
              "type" => "regular",
              "status" => "paused",
              //"schedule_time" => $form_data['post_date'],
              "schedule_time" => "2020-09-15T15:00:00+00:00",
              "timewarp" => false,
              "batch_delivery" => array(
                  "batch_delay" => 0,
                  "batch_count" => 0
                  ),
              "settings"  => array(
                  "subject_line"  => $form_data['lbu_subject'],
                  "title"         => $form_data['post_title'],
                  "from_name"     => $form_data['lbu_from'],
                  "reply_to"      => get_option('lubuvna-company-email'),
                  "template_id"   => 99999,
                  )
    );

若要正确执行此操作，当条件为非真时，应将空数组分配给

$segment\u opts

，而不是空字符串

} else {
    $segment_opts = array();
}
