我需要检查类别：13,210,311,312

修改

完整代码：

if ( in_array( 13, $cats ) ) {
        return TRUE;
    }

感谢您的帮助！

Answer 1

虽然你的问题真的很模糊我想你要检查13,210,311,312是否在$ cats中，然后我们这个片段：

<?php
$array = array( 13, 210, 311, 312 );
$cats  = array( 13, 210, 111111, 5555, 66666, 77777, 311, 312 );
if( $array == array_intersect( $array, $cats ) ){
    return true;
}

<强>更新

所以我想我知道你想要什么，但我不确定。无论如何这里是更新的功能。

function lw_gpf_exclude_product($excluded, $product_id, $feed_format) {
    // Return TRUE to exclude a product, FALSE to include it, $excluded to use the default behaviour.
    $cats = wp_get_post_terms( $product_id, 'product_cat', array( 'fields' => 'ids' ) );
    // https://codex.wordpress.org/Function_Reference/wp_get_post_terms
    // check to make sure the response in not wp error, see Return Values
    if( ! is_wp_error( $cats ) ){
        $check = array( 13, 210, 311, 312 );
        $ids = array();
        // each array element is an object, see Variables in Returned Object
        // method 1: more reliable
        foreach( $cats as $cat ){
            $ids[] = $cat->term_id;
        }
        if( $check == array_intersect( $check, $ids ) ){
            return true;
        }
        // method 2: just compares the number of elements found
        $check = array( 13, 210, 311, 312 );
        $count = 0;
        foreach( $cats as $cat ){
            if( in_array( $cat->term_id, $check ) ){
                $count++;
            }
        }
        if( $count === count( $check ) ){
            return true;
        }
    }
    return $excluded;
}

Answer 2

您可以使用foreach looop检查所有类别，例如

$array = array('mykey' => 'myvalue', 'mykey2'=> 'myvalue2', 'mykey3'=> 'myvalueN');
foreach($array as $key=> $item){
  if ( in_array( $key, $cats ) ) {
      echo "Key or id is available";
  }
}

参考：http://php.net/manual/en/function.in-array.php

Answer 3

你可以使用foreach循环

<?php
$categories = [13, 210, 311, 312];
foreach ($categories as $category) {
if (in_array ($category, $cats) {
echo "{$category} is in array!";
}
}
?>

如何使用PHP in_array（）函数？
