i think we can make the topic Resolved

Sure!! thanks again

I have figure out sth different to do the same thing.

<article>
	<?php
		$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
		$temp = $wp_query;
		$wp_query= null;
		$wp_query = new WP_Query();
		$args = array(
		'posts_per_page' => 2,
		'cat'            => 7,
		'paged'          => $paged,
		);
		$wp_query->query( $args );
		while ( $wp_query->have_posts() ) : $wp_query->the_post();
		$post_id = get_the_ID();
	?>
	<?php
		$title = get_the_title();
		if (strlen($title) > 20) {
			$title = substr($title, 0, 18) . '...';
		}
	?>
	<h2><a href="<?php the_permalink(); ?>"><?php echo $title; ?></a>   <?php the_time('F jS, Y') ?></h2>
	<?php the_post_thumbnail('thumbnail');?>
	<p>
	<?php
		$excerpt = get_the_excerpt();
  		echo string_limit_words($excerpt,56);
	?>
	</p>

	<p class="read_more">Read the full post <a href="<?php the_permalink(); ?>">here</a></p>
	<?php endwhile;
		$page_navi = function_exists('wp_pagenavi') ? true : false ;
		($page_navi) ? wp_pagenavi() : posts_nav_link();
	?>
	<?php wp_reset_postdata(); ?>
	<?php $wp_query = null; $wp_query = $temp; ?>
</article>

to use the_post_thumbnail(), i had to add to my functions.php:
add_theme_support( ‘post-thumbnails’ );

And change the way to attach images to the posts: inside the post, click no “Set featured image”.

I hope it helps ?? this is where i took it from… https://www.ads-software.com/support/topic/no-image-showing-in-single-post?replies=5

Thanks a lot CarletonU for your answer and your time.

For the first price of code…

I had already added the line:
add_theme_support( ‘post-thumbnails’ );

But i kept attaching the image from the Media Library. Now i do as you said, and it is working!

Thanksssssssssssssss a looooot

i have also tried this code

<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
	<?php echo $post_id = get_the_ID();?>
	<h2><?php the_title(); ?></h2>
	<h3><?php the_time('F jS, Y') ?></h3>
	<?php echo wp_get_attachment_image($post_id, 'full');?>
	<p><?php the_content(); ?></p>
<?php endwhile; ?>
<nav>
	<?php previous_post_link('%link', '< Previous ' , in_same_cat, 'excluded_categories'); ?>
	<?php next_post_link('%link', ' Next > ', in_same_cat, 'excluded_categories'); ?>
</nav>

the images were attached to the posts from the Media Library. This means:
I created a post and published it.
Then i went to the Media Library and Add a new image.
From the Media Library i clicked “attach” to attach the image to the post.

I dont know whats happening, i was supposed to be easy o.O

oh, i see!! thanks a lot for the explanation.

by the way, since the image is in the Media library, i attach it to the post, and everything works perfect!!

Thankssssssssss

You are right, frizax.
When i went to the Media Library, there is no image attached to the post, but my doubt now is:
I could attached the image when i created the post, and i still can see it. When i preview the post, i see the image as well, but it is not in the media library.
What is happening?

hi! thanks a lot for your answers and your time.

frizax, I have done your suggested debugging and in the sencond one, it says ’empty’.
But i have an image attached to the post (attached when i created the post in WP admin panel), and actually i can see it when i see the single post.
weird :S

maybe i can use also some advice. This is the first time i try to do a blog, and im not sure if i did right using query(), for example.

keesiemeijer, thanks a lot, that works perfectly.
Anyway, I was checking other posts, and i found this, which helped, although it does not use wp_query.

I did what you said, Stefan, and it is working perfectly and exactly how i wanted.

I would like to solve that as well, exactly the same.
