未定义的索引:pretashop selection helper中的id_选项错误

prestashop-1.7 smarty prestashop php

我正试图为一个预启动模块设置一个时区下拉列表。我遵循了这个例子- http://doc.prestashop.com/display/PS16/Using+the+HelperForm+class#UsingtheHelperFormclass-Selector

这是我用来获取时区列表的代码:

function timezones() {
        $timezones = [];

        foreach (timezone_identifiers_list() as $timezone) {
            $datetime = new \DateTime('now', new DateTimeZone($timezone));
            $timezones[] = [
                'sort' => str_replace(':', '', $datetime->format('P')),
                'offset' => $datetime->format('P'),
                'name' => str_replace('_', ' ', implode(', ', explode('/', $timezone))),
                'timezone' => $timezone,
            ];
        }

        usort($timezones, function($a, $b) {
            return $a['sort'] - $b['sort'] ?: strcmp($a['name'], $b['name']);
        });

        return $timezones;
    }

然后,我尝试按照文档中的说明执行此操作-

        $timezoneList = timezones();    
    $options = array();
    foreach ($timezoneList as $timezone)
    {
      $options[] = array(
        "id" => $timezone['offset'],
        "name" => '(UTC '.$timezone['offset'].') '.$timezone['name'].''
      );
    }

我的结果生成了一个下拉列表,其中包含我想要的列表,但值为空,并引发以下错误- 请注意文件f中的第786行:xampp\htdocs\presta02\vendor\prestashop\smarty\sysplugins\smarty\u internal\u templatebase.php(157):eval()'d code [8]未定义的索引:id_选项

我的目标是得到这样的东西-

<option value="-11:00">(UTC -11:00) Pacific, Midway</option>

现在我明白了-

<option value="">(UTC -11:00) Pacific, Midway</option>

如果您使用了文档中的此部分

array(
    'type' => 'select',                              // This is a <select> tag.
    'label' => $this->l('Shipping method:'),         // The <label> for this <select> tag.
    'desc' => $this->l('Choose a shipping method'),  // A help text, displayed right next to the <select> tag.
    'name' => 'shipping_method',                     // The content of the 'id' attribute of the <select> tag.
    'required' => true,                              // If set to true, this option must be set.
    'options' => array(
        'query' => $options,                           // $options contains the data itself.
        'id' => 'id_option',                           // The value of the 'id' key must be the same as the key for 'value' attribute of the <option> tag in each $options sub-array.
        'name' => 'name'                               // The value of the 'name' key must be the same as the key for the text content of the <option> tag in each $options sub-array.
    )
),

那么您的$options数组中必须有相同的键。意思是你必须用这个

$timezoneList = timezones();    
$options = array();
foreach ($timezoneList as $timezone)
{
  $options[] = array(
    "id_option" => $timezone['offset'],
    "name" => '(UTC '.$timezone['offset'].') '.$timezone['name'].''
  );
}

或将选定项的定义选项键从 id_option 到 id

'options' => array(
     'query' => $options,                           // $options contains the data itself.
     'id' => 'id',                                  // The value of the 'id' key must be the same as the key for 'value' attribute of the <option> tag in each $options sub-array.
     'name' => 'name'                               // The value of the 'name' key must be the same as the key for the text content of the <option> tag in each $options sub-array.
)

顺便说一下,这条评论还说

// The value of the 'id' key must be the same as the key for 'value' attribute of the <option> tag in each $options sub-array.
