在插件中输出变量 [英] Outputting variables within a plugin

问题描述

从这个问题开始，我现在正在尝试对插件进行重新设计，以便可以这样做:

Following on from this question, I'm now trying to rework the plugin so that I can do:

{exp:deetector}
     {user_agent}
     {hash}
{/exp:deetector}

但是使用下面的代码，我没有输出:

but with the code below, I get no output:

public function __construct()
{
    $this->EE =& get_instance();

    include(PATH_THIRD.'/deetector/libraries/detector.php');

    $this->ua = $ua;

    $tagdata = $this->EE->TMPL->tagdata;

    $variables[] = array(
        'user_agent'   => $this->ua->ua,
        'hash'         => $this->ua->uaHash,
        'browser_os'   => $this->ua->full,
        'browser'      => $this->ua->browser,
        'browser_full' => $this->ua->browserFull
    );

    return $this->EE->TMPL->parse_variables($tagdata, $variables);
}

如果我对上面列出的每个变量执行$this->return_data = $this->ua->xx，我将得到输出，但如果我解析$ variables数组，则不会得到输出.

If I do $this->return_data = $this->ua->xx for each of the variables listed above I get output, but not if I parse the $variables array.

我也尝试过$variables = array，但得到未定义偏移量:0 .

推荐答案

如果仅使用构造函数进行输出，请确保插件类具有公共属性return_data，其中包含解析的tagdata:

If you're just using the constructor for output, make sure the plugin class has a public property return_data which contains the parsed tagdata:

$this->return_data = $this->EE->TMPL->parse_variables($tagdata, $variables);

对于该类中的任何其他方法，您只需按照示例返回分析的数据即可.

For any other method in the class, you can just simply return the parsed data, as per your example.

作为旁注，我认为您不在此处循环任何数据.考虑改用parse_variables_row方法，因此省略了count，total_results和switch之类的多余变量.使用该方法不需要嵌套数组，因此可以归结为:

As a sidenote, I take it you're not looping any data here. Consider using the parse_variables_row method instead, so extra variables like count, total_results and switch are omitted. Using that method doesn't require a nested array, so it would come down to this:

$variables = array(
    'user_agent' => $this->ua->ua,
    ...
);

$this->return_data = $this->EE->TMPL->parse_variables_row($tagdata, $variables);
