I guess you’ld like to feature that on you home page right?
I’m doing something similar and my solution is to use a script that shows the latest post of a given category. with another piece of php I also add the first image of that post and below adding title and excerpt is very simple.
<?php query_posts ('cat=5&showposts=1'); ?> //here you can change the category ID or the namber of posts to show
<?php while (have_posts()) : the_post(); ?>
<a class="title" href="<?php the_permalink() ?>" rel"">
<div class="picture">
<img class="c" src="<?php getImage('1'); ?>//this is the part that grabs the first picture of your post
</a>
</div><!--picture-->
<div class="first_article">
<a class="title_main" href="<?php the_permalink() ?>"><h3><?php the_title(); ?></h3></a>
<p class="text"><?php the_excerpt() ?>
</p>
<ul class="mini_post"> <li class="rm"><a class="read_more" href="<?php the_permalink() ?>"><span>Read more</span></a><li>
<li class="cm"><a class="comments" href="<?php the_permalink() ?>"><span>Comments <?php comments_number('0', '1', '%'); ?></span></a><li>
</ul>
<?php endwhile;?>
ok, you don’t have to use this html structure, I just grabbed my own code and for some reasons I build it like that.
so, at the beginning I’m retrieving 1 post from a given category but you could also retrieve a particular post with this code:
<?php
// retrieve one post with an ID of 5
query_posts('p=5');
?>
then I have a div for the picture and here you can only see the tag I used to retrieve the image but there’s also a code to put in the function.php
you can find the instructions here: https://bavotasan.com/tutorials/retrieve-the-first-image-from-a-wordpress-post/
then were I wanted the text I used the <? php the_excerpt () ?>
and it shows the excerpt you wrote on your admin panel when you wrote the article. if instead you used the tag <!--more-->
inside the article then you have to use <? php the_content () ?>
fianlly where you see the unordered list I also added a “read more” link and a “comment” link which also shows the current number of comments for that post.
All this stuff is in a template I created for the home page so this is all stuff you need to put in a template. even the index or the single page, is up to you.
However it’s the first time that I deal with wordpress so I can’t be of much help but look at this link to find more tips. they really helped me:
