Excluding/Removing Specific Tags in WordPress
Excluding specific tags from the tag list with the_tag seemed challenging. However, I figured out a way using get_the_tags, and I wanted to share it with you. Additionally, I noticed a previous blog post that quoted an article about wanting to exclude multiple specific tags on the IT engineer-focused Q&A site, Teratail. So, I’ve modified the code to handle multiple tags using arrays.
<?php
$exclude_tags = array("tag1", "tag2", "tag3"); // Array of tags to be excluded by their slugs
$tags = get_the_tags($post->ID);
$separator = ', ';
$output = '';
if ($tags) {
foreach ($tags as $tag) {
if (!in_array($tag->slug, $exclude_tags)) { // If the tag slug is not included in the excluded tags
$output .= '<a href="' . get_tag_link($tag->term_id) . '">' . $tag->name . '</a>' . $separator;
}
}
echo trim($output, $separator);
}
?>
On the other hand, if you want to display a list of tags in a select box and need to exclude/remove specific tags, you can use code like the following:
<?php
$excluded_tag = array('tag1', 'tag2', 'tag3'); // Array of tags to be excluded by their slugs
$tags = get_tags();
$filtered_tags = array();
if ($tags) {
foreach ($tags as $tag) {
if (!in_array($tag->slug, $excluded_tag)) {
$filtered_tags[] = $tag;
}
}
}
if (!empty($filtered_tags)) :
?>
<select onchange="document.location.href=this.options[this.selectedIndex].value;" class="custom-select form-control-sm">
<?php foreach ($filtered_tags as $tag) : ?>
<option value="<?php echo esc_url(get_tag_link($tag->term_id)); ?>"><?php echo esc_html($tag->name); ?></option>
<?php endforeach; ?>
</select>
<?php endif; ?>
