如何在WordPress中按选定的标签显示帖子？

Question

Is it possible to show a post by selected tags? I tried to do some research on Google, but I can't get it. I have faced this problem and I am stuck.

I have created a new WordPress post

ex.

Lasagne and I tags it as Sweet-Food,Creamy-Food
Noodles and the tags = Spicy-Food,Sweet-Food

On the page I wanted to show the Sweet-Food tags and it will show Noodles and Lazagna. Is this possible?

Answer 1

Yes its possible

function get_tags_post($tag_name)
{
    $original_query = $wp_query;
    $wp_query = null;
    $brand_name= $tag_name;
    $args=array('posts_per_page'=>5, 'tag' => $brand_name);
    $wp_query = new WP_Query( $args );
    if ( have_posts() ) :
        while (have_posts()) : the_post();
            echo '<li>';
            the_title();
            echo '</li>';
        endwhile;
    endif;
    $wp_query = null;
    $wp_query = $original_query;
    wp_reset_postdata();
}

Pass the tag name in the variable $brand_name and you can get the post related to the tag

If you want to get the tag list you can achieve that from the below code

<?php
$posttags = get_the_tags(); // gives you the list of all tags 
if ($posttags) {
  foreach($posttags as $tag) {
    echo '<img src="http://example.com/images/' . $tag->term_id . '.jpg" 
alt="' . $tag->name . '" />'; 
  get_tags_post($tag->name); // pass the dynamic names to the function and it will return the post of the particular tag 
  }
}
?>
