我在下面出现错误...

I'm getting the error below...

警告：implode（）[function.implode]：在\wp-content / themes中传递的参数无效/mytheme/functions.php第1335行

Warning: implode() [function.implode]: Invalid arguments passed in \wp-content/themes/mytheme/functions.php on line 1335

at ...

function my_get_tags_sitemap(){
    if ( !function_exists('wp_tag_cloud') || get_option('cb2_noposttags')) return;
    $unlinkTags = get_option('cb2_unlinkTags'); 
    echo '<div class="tags"><h2>Tags</h2>';
    if($unlinkTags)
    {
        $tags = get_tags();
        foreach ($tags as $tag){
            $ret[]= $tag->name;
        }
        //ERROR OCCURS HERE
        echo implode(', ', $ret);
    }
    else
    {
        wp_tag_cloud('separator=, &smallest=11&largest=11');
    }
    echo '</div>';
}

任何想法如何拦截错误。该网站只有一个标签。

Any ideas how to intercept the error. The site has exactly one tag.

推荐答案

您收到错误，因为 $ ret 不是一个数组。

You are getting the error because $ret is not an array.

为了摆脱错误，在函数开始时，用这一行定义它： $ ret = array（）;

To get rid of the error, at the start of your function, define it with this line: $ret = array();

看起来get_tags（）调用什么也没有返回，所以foreach没有运行，这意味着$ ret未定义。

It appears that the get_tags() call is returning nothing, so the foreach is not run, which means that $ret isn't defined.
