How to limit the number of tag links displayed for a WordPress post

To limit the number of tag links displayed for a WordPress post, you can create a custom function and use the the_tags() function with a custom loop. Add the following code snippet to your theme’s functions.php file:

1. In your WordPress admin dashboard, go to “Appearance” > “Theme Editor.”
2. In the right sidebar, locate and click on the “functions.php” file.
3. Add the following code snippet at the end of the file:

function display_limited_tags($limit = 5) {
$post_tags = get_the_tags();

if ($post_tags) {
$count = 0;
foreach ($post_tags as $tag) {
if ($count >= $limit) {
break;
}
echo '<a href="' . get_tag_link($tag->term_id) . '">' . $tag->name . '</a>, ';
$count++;
}
}
}

This code snippet creates a custom function called display_limited_tags() that accepts a parameter $limit, which sets the maximum number of tags to display. The default value is 5. You can change the default value or pass a different value when calling the function.

4. Click “Update File” to save the changes.
5. In your theme’s template file (e.g., single.php), locate the place where you want to display the limited tags and replace the default the_tags() function with the custom display_limited_tags() function. For example:

<?php display_limited_tags(3); ?>

This example limits the number of tags displayed to 3. You can change the number to your desired limit.

6. Save the changes to the template file.

Now, when you visit a post on your WordPress site, only the limited number of tags will be displayed.

Remember to always backup your files before making any changes, and test your changes on a staging site or local development environment before applying them to your live site.
