Php 如何将wordpress短代码更改为数组

我在添加数组时出现语法错误。有人能指出我在哪里犯了错误吗

function commresi() {
                ob_start();
                ?>     
<?php if( has_term=array('commercial',’commercial-filtration’,'commercial-water-softeners’,’category') ) { ?>
      <p class="commercial com-res"><a href="/home">Visit Residential Systems</a></p>
<?php  } else { ?>
      <p class="not-commercial com-res"><a href="/commercial">Visit Commercial Systems</a></p>
  <?php } ?>

<?php
                return ob_get_clean();
}
add_shortcode('comres', 'commresi');

---

在ob_开始之前忘记打开php标记，在声明has_term变量时忘记美元符号$，在代码末尾忘记关闭php标记

function commresi() 
{
    <?php
        ob_start();
    ?>     
    <?php

        if ($has_term = array(
            'commercial',
            ’commercial - filtration’,
            'commercial-water-softeners’,’category'
        ))

    { ?>
          <p class="commercial com-res"><a href="/home">Visit Residential Systems</a></p>
    <?php
    }
    else
    { ?>
          <p class="not-commercial com-res"><a href="/commercial">Visit Commercial Systems</a></p>
      <?php
    } ?>

    <?php
        return ob_get_clean();
    ?>
}
add_shortcode('comres', 'commresi');

忘记了$sign之前有\u术语变量

使用此代码：

function commresi() { 
$commercial_array = array('commercial','commercial-filtration','commercial-water-softeners','category');
$return  = ' <p class="not-commercial com-res"><a href="/commercial">Visit Commercial Systems</a></p>';

if( in_array ($has_term, $commercial_array)  ) {
    $return = ' <p class="commercial com-res"><a href="/home">Visit Residential Systems</a></p>';
}
return $return; 
}   

add_shortcode('comres', 'commresi');

其中，$has_term是要从$commercial_数组中匹配的术语

function commresi() { 
$commercial_array = array('commercial','commercial-filtration','commercial-water-softeners','category');
$return  = ' <p class="not-commercial com-res"><a href="/commercial">Visit Commercial Systems</a></p>';

if( in_array ($has_term, $commercial_array)  ) {
    $return = ' <p class="commercial com-res"><a href="/home">Visit Residential Systems</a></p>';
}
return $return; 
}   

add_shortcode('comres', 'commresi');
