使用PHP的Select2 optgroup格式

我有一个ajax调用,该调用获取动态数据并将其放置在select2中,如下所示:

$.ajax({
    type: 'get',
    url: '/api/?stuff='+c,
    dataType: "json",
    success: function (response) {
        // If select2 is already defined, we destroy it and rebuild it with the new data
        if(typeof $(".select2edit").data('select2') !== 'undefined') {
            $(".select2edit").select2('destroy').select2({ data: response, width: '100%', closeOnSelect: false });
        } else {
            $(".select2edit").select2({ data: response, width: '100%', closeOnSelect: false });
        }
    }
});

我使用PHP创建响应,然后在发送响应之前将其转换为JSON:

$old_emplacement = '';
$results = array();
$i = -1;

while($array_campaign = tep_db_fetch_array($campaign)){
    if ($array_campaign['name'] != $old_emplacement) {
        $i++;
        $results['results'][$i]['text'] = $array_campaign['name'];
        $old_emplacement = $array_campaign['name'];
        $c = 0;
    }
    $results['results'][$i]['children'][$c]['id'] = $array_campaign['id'];
    $results['results'][$i]['children'][$c]['text'] = $array_campaign['c_name'];
    $c++;
}

$results['pagination']["more"] = true; 

因此产生以下JSON格式:

{
  "results": [
    { 
      "text": "Name 1", 
      "children" : [
        {
            "id": 1,
            "text": "Text 1.1"
        },
        {
            "id": 2,
            "text": "Text 1.2"
        }
      ]
    },
    { 
      "text": "Name 2", 
      "children" : [
        {
            "id": 1,
            "text": "Text 2.1"
        },
        {
            "id": 2,
            "text": "Text 2.2"
        }
      ]
    }
  ],
  "paginate": {
    "more": true
  }
}

当select2初始化并加载时,我得到一个No results found.。而且我不知道为什么。就documentation来说,这是正确的格式,而other questions似乎可以证实。任何想法可能出在哪里?

还应注意,我的select2位于模式内部的表单中,这是html:

<select name="xx[]" id="edit-xx" name='xx' class="form-control select2edit" multiple>
</select>

问题出在我的PHP代码生成的格式上。我将结果发布在这里,供尝试使用PHP生成select2 optgroup格式的任何人以及我自己的参考文献:

$old_emplacement = '';

$results = array();
$i = -1;

while($array_campaign = tep_db_fetch_array($campaign)){
    if ($array_campaign['name'] != $old_emplacement) {
        $i++;
        $results[$i]['text'] = $array_campaign['name'];
        $old_emplacement = $array_campaign['name'];
        $c = 0;
    }
    $results[$i]['children'][$c]['id'] = $array_campaign['id'];
    $results[$i]['children'][$c]['text'] = $array_campaign['c_name'];
    if(in_array($array_campaign['id'], $campaigns_array)) {
        $results[$i]['children'][$c]['selected'] = true;
    }
    $c++;
}
