是否有人知道如何使此页面模板仅显示知识库帖子类型？我尝试过各种不同的方法，但没有成功

<?php

 $catCounter = 7;
 foreach($categories as $category) { 
 $catCounter++;
 if ($catCounter == 1) { 
 echo \'</div><div class="row knowledge-base">\';
 } 
 elseif ($catCounter == 8) {
 $catCounter = 1;
 echo \'<div class="row knowledge-base">\';
 }
 elseif ($catCounter == 3) { 
 $catCounter = 0;
 }
