如何将键列表数组与 wordpress post 与 array_intersect 的 "cat_name" 数组进行比较

How to compare an array of list of keys with an array of "cat_name" of wordpress post with array_intersect

我创建了这段代码:

 <?php 
             $lisections = array('anglais','boxe-thai','Cyclotourisme','Danse-modernjazz–grs–classique','danse-sportive','dessin-peinture','escrime','Espagnol','gym-tonic','gymnastique-de-detente','gymnastique-enfantine-et-sportive','Gymnastique-senior','handball','hatha-yoga','histoire-de-lart','judo - ju jitsu','Karate','kendo-iaido','natation','ninjutsu','petanque','photo-club','randonnees-pedestres','refection-fauteuils','Sportives','subaquatique','tennis-de-table','tennis-de-table–senior','Tir','gym-dentretient-top-gym','sections-arts-martiaux','sections-langues','sections-gymnastique', 'section-aquatique','section-tennisdetable' );
            foreach((get_the_category()) as $cat) { 
                                $displaycat[] = $cat->cat_name . ' '; 
             }
              //print_r($displaycat);
            $onesection=array_intersect($lisections,$displaycat);
            print_r($onesection);?>

但是没用。

$displaycat 显示:Array ( [0] => Accueil [1] => Evénements [2] => hatha-yoga [3] => Sections ).

print_r($onesection)的结果;是一个空数组而不是 Array([0] => hatha-yoga.

我的目标是获取类别名称"hatha-yoga"之一post生成一个link到return本节[=24]的主页=].

您的 $displaycat 条目有尾随 space ($displaycat[] = $cat->cat_name . ' ';)。你的 $lisections 没有。

试试 $displaycat[] = $cat->cat_name;(没有串联)。
