HAS_CATEGORY未正常工作

时间：2017-01-06 作者：Alex

在我的website 我想用一个星形图标标记特色文章，它通过检查一篇文章是否有“特色”类别来工作。然而，对于回溯的文章，它似乎总是返回真的，这真的很奇怪。（例如，计算机->编程最佳实践下面的所有内容都被错误地标记为特色！）。更让人尴尬的是，这些过时的文章甚至都不需要使用它，而且对于每一篇特色文章来说，都有足够奇怪的两次。

这是我的函数代码。php：

function showPosts($number, $category="", $description = false, $disambiguation = null, $featured = false, $collapsible = true, $thumbnail = false, $languageFlag = true)
{
    global $post;

            $args = array(
              \'numberposts\'       =>   $number,
              \'category_name\'     =>   $category
            );

    $myposts = get_posts($args); 

    if( $myposts )
    {   
        // hidden posts due to language setting
        $hiddenPosts = 0;

        // get cookie data (prefered language(s))
        if(isset($_COOKIE["post-data"])) :
            $allowedLanguages = get_tangboshi_cookies();
        else:
            $allowedLanguages = array();
        endif;

        // if language setting has not been set, allow all
        // not very elegant to have all the stuff in a single array (post-data), with multiple arrays one could use array.empty();

        if( !(in_array("posts-english", $allowedLanguages) || in_array("posts-german", $allowedLanguages)) ) :
            array_push($allowedLanguages, "posts-english");
            array_push($allowedLanguages, "posts-german");
        endif;

        foreach( $myposts as $post ) 
        {
            setup_postdata($post);

            $id = convertText(get_the_title())."-".$disambiguation;
            $postID = get_the_ID();

            $status = get_post_meta($postID, "status", true);

            switch ($status)
            {
                case "": $statusText = ""; break;
                default: $statusText = \'<span class="caption-draft"> - \'.$status.\'</span>\'; break;
            }

            if ( $featured ) : 
                $id .= "-featured";
            endif;

            // same problem with has_category(\'Featured\')
            if ( in_category(\'Featured\') )
            {
                // every featured article mentioned twice; BUG!!
                // backdated always get start...
                $icon = \'star\';
            }


            // get language of current post
            $language = get_post_meta($postID, "language", true);

            // if language not mentioned, default is English
            if ( !$language )
            {
                $language = "english";
            }

在我的index.php 我打电话"createMainPanel(...)", showPosts(...) 作为call\\u userf\\u func\\u数组的回调调用panelAllPostsParams(...):

循环每次迭代后，您都不会重置图标变量，因此，一旦它成为“星”，它将始终保持不变。

SO网友:montrealist

我怀疑你没有使用get_posts 正确（看起来你在混音WP_Query 方法，例如the_post 在中，结果来自get_posts). 请阅读以下内容的区别WP_Query 和get_posts, 例如here.

您是否尝试将当前帖子ID传递到in_category?

if ( in_category(\'Featured\', $post->ID) )
