Hi everyone.

I’m creating a code to show the information of PDF documents, but I can see the result, because it’s seems to be that I made a mistake, but I can’t found it.

Updated code:

<!-- MOSTRAR CAMPOS PERSONALIZADOS -->

	<!-- Documento principal -->

		<?php
	$attachment_id = get_field('archivo');
	$url = wp_get_attachment_url($attachment_id);
	$title = get_the_title($attachment_id);
	$path_info = pathinfo(get_attached_file($attachment_id));
	$filesize = filesize( get_attached_file( $attachment_id ) );
	$filesize = size_format($filesize, 2);

		if(get_field('archivo')): ?>
			<div class="titulos_secundarios">Ver documento:</div><br/><br/>
			<a href="<?php echo $url; ?>" target="_blank" title="Abrir documento en una nueva pestaña" style="display: inline;"><?php echo $title?>.<?php echo $path_info['extension'];?> (<?php echo $filesize; ?>)</a>
		<?php 
		endif; 
?>
	<!-- Documento secundarios -->

		<br/>
		<div class="titulos_secundarios">Antecedentes</div>
		<br/>

<?php if(have_rows('otros_archivos')):
	while (have_rows('otros_archivos')) : the_row();
	$post_object = get_sub_field('antecedente');
		echo "<ol>";
		if($post_object): 
			$post = $post_object; setup_postdata($post); ?>
			<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
		<?php wp_reset_postdata();
		else:
			echo "<li>No se ha incluido ningún antecedente aún.</li><br/>";
		endif;
	echo "</ol>";
	endwhile;
endif; ?>
<!-- FIN MOSTRAR CAMPOS PERSONALIZADOS -->

Thanks in advance.

First error is a missing <?php tag on line 10, it should be

<?php if(get_field('archivo')): ?>

I can resolve my problem, however the last loop doesn’t work. The loop repeat the same information and it shows the title and link of the current post.

Code:

<?php if(have_rows('otros_archivos')):
	while (have_rows('otros_archivos')) : the_row();
	$post_object = get_sub_field('antecedente');
		echo "<ol>";
		if($post_object): 
			$post = $post_object; setup_postdata($post); ?>
			<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
		<?php wp_reset_postdata();
		else:
			echo "<li>No se ha incluido ningún antecedente aún.</li>";
		endif;
	echo "</ol>";
	endwhile;
endif; ?>

You can see the results on this webpage.

Is your code inside a template file that is loaded using one of the standard WP functions for loading a template file of some kind? like get_templat_part() how is this file loaded? Where is the code located?

The code is located on the file “content.php” of the theme Stargazer. I can’t found a standard function. The complete code is presented bellow:

<article <?php hybrid_attr( 'post' ); ?>>

	<?php if ( is_singular( get_post_type() ) ) : // If viewing a single post. ?>

		<header class="entry-header">

			<h1 <?php hybrid_attr( 'entry-title' ); ?>><?php single_post_title(); ?></h1>

			<div class="entry-byline">
				<span <?php hybrid_attr( 'entry-author' ); ?>><?php the_author_posts_link(); ?></span>
				<time <?php hybrid_attr( 'entry-published' ); ?>><?php echo get_the_date(); ?></time>
				<?php comments_popup_link( number_format_i18n( 0 ), number_format_i18n( 1 ), '%', 'comments-link', '' ); ?>
				<?php if ( function_exists( 'ev_post_views' ) ) ev_post_views( array( 'text' => '%s' ) ); ?>
				<?php edit_post_link(); ?>

I just took a quick look at the theme, since for a change I could actually look at a themes code. The answer is, no, the theme does not use standard WP functions to include template files. What this means is that the standard global variables (like $post) are not available.

I think you can correct this by simply declaring the global variables that you need to access, in this case $post

<?php if(have_rows('otros_archivos')):
	global $post; // add this
	while (have_rows('otros_archivos')) : the_row();
	$post_object = get_sub_field('antecedente');
		echo "<ol>";
		if($post_object): 
			$post = $post_object; setup_postdata($post); ?>
			<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
		<?php wp_reset_postdata();
		else:
			echo "<li>No se ha incluido ningún antecedente aún.</li><br/>";
		endif;
	echo "</ol>";
	endwhile;
endif; ?>
