Woocommerce Get product tags in array
提问by Gas
I want to get the product tags of the woocommerce products in an array, for doing if/else logic with it (in_array), but my code doesn't work:
我想在一个数组中获取 woocommerce 产品的产品标签，以便对其进行 if/else 逻辑（in_array），但我的代码不起作用：
<?php
$aromacheck = array() ;
$aromacheck = get_terms( 'product_tag') ;
// echo $aromacheck
?>
When echoing $aromacheck, I only get empty Array, though the product tags are existing - visible in the post class.
当回显 $aromacheck 时，我只得到空数组，尽管产品标签存在 - 在 post 类中可见。
How can I get the product tags in an array correctly?
如何正确获取数组中的产品标签？
Solution (thanks Noman and nevius):
解决方案（感谢 Noman 和 nevius）：
/* Get the product tag */
$terms = get_the_terms( $post->ID, 'product_tag' );
$aromacheck = array();
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
foreach ( $terms as $term ) {
$aromacheck[] = $term->slug;
}
}
/* Check if it is existing in the array to output some value */
if (in_array ( "value", $aromacheck ) ) {
echo "I have the value";
}

You need to loop through the array and create a separate array to check in_arraybecause get_termsreturn objectwith in array.
您需要遍历数组并创建一个单独的数组进行检查，in_array因为get_terms返回object数组中。
$terms = get_terms( 'product_tag' );
$term_array = array();
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
foreach ( $terms as $term ) {
$term_array[] = $term->name;
}
}
So, After loop through the array.
所以， After 循环遍历数组。
You can use in_array().
Suppose $term_arraycontains tag black
您可以使用in_array()。
假设$term_array包含标签黑色
if(in_array('black',$term_array)) {
echo 'black exists';
} else {
echo 'not exists';
}

I had to parse an args-array to the get_terms function. Maybe this help other aswell.
我必须将 args 数组解析为 get_terms 函数。也许这也有助于其他人。
$args = array(
'number' => $number,
'orderby' => $orderby,
'order' => $order,
'hide_empty' => $hide_empty,
'include' => $ids
);
$product_tags = get_terms( 'product_tag', $args );

$args = array(
'number' => $number,
'orderby' => $orderby,
'order' => $order,
'hide_empty' => $hide_empty,
'include' => $ids
);
$product_tags = get_terms( 'product_tag', $args );
//only start if we have some tags
if ( $product_tags && ! is_wp_error( $product_tags ) ) {
//create a list to hold our tags
echo '<ul class="sb-tag">';
//for each tag we create a list item
foreach ($product_tags as $tag) {
$tag_title = $tag->name; // tag name
$tag_link = get_term_link( $tag );// tag archive link
echo '<li class="sidebar-list-tag" ><a href="'.$tag_link.'"> <span>'.$tag_title.' </span></a></li>';
}
echo '</ul>';
}
