Generate Thumbnails of Category WordPress
- SOLVED
Hello,
On single post pages we would like to display thumbnails of other posts in the same category. The thumbnail is a custom field value called "thumbnail" which every post has.
In the single post .php is this code:
<?php $theme_options = get_option('Grace'); ?>
<?php if (!isset($theme_options["autothumb"]) || $theme_options["autothumb"] == "timthumbon") {
include (TEMPLATEPATH . '/includes/postautothumbson.php');
}
else if (!isset($theme_options["autothumb"]) || $theme_options["autothumb"] == "timthumboff") {
include (TEMPLATEPATH . '/includes/postautothumbsoff.php');
} ?>
That calls to "postautothumbsoff.php" in this case since automatic thumbnails are turned off.
In "postautothumbsoff.php" the code is the following:
<?php
$i = 1; // set variable used to control which style is applied to thumbnail
if (have_posts()) : while (have_posts()) : the_post(); // check if there are any posts
if ($i % 2 == 0) { // check if $i is divisible by 2 with no remainder then apply style to variable $c
$c = ' class="alt"';
} else {
$c = '';
}
$post_id = $post->ID;
$single = true;
$key = thumbnail;
$thumbnail_value = get_post_meta($post_id, $key, $single);
if ( $thumbnail_value ) : // retreive thumbnail custom field value
?>
<li<?php echo $c ?>>
<a href="<?php the_permalink() ?>" class="thumbhover">
<img src="<?php echo $thumbnail_value; ?>" alt="<?php the_title('','',False); ?> "/>
</a><div class="luisthumb">
<?php
{ $luisthumb = get_post_meta
($post->ID, 'luisthumb', $single = true);
if($luisthumb !== '') echo $luisthumb;} ?>
</div>
</li>
<?php $i++; else :?>
<li<?php echo $c ?>><a href="<?php the_permalink() ?>"><strong><?php the_title(); ?></strong></a><br/><?php the_excerpt(); ?></li>
<?php $i++; endif; endwhile; endif; ?>
Currently it is not working. It only shows the thumbnail of the single post. Instead it should show all thumbnails of the posts category.
The link to a single post is:
http://piersrueb.com/blog/archives/96
The link to the categories page is:
http://piersrueb.com/blog/archives/category/commercials
All the thumbnails there displayed should also show up on the single post pages.
Thank you for your help.

replace
$key = thumbnail;
$thumbnail_value = get_post_meta($post_id, $key, $single);
by
$key = 'thumbnail';
$thumbnail_value = get_post_meta(get_the_ID(), $key, $single);
var_dump($thumbnail_value);
what the output on a category php?
and is category php has this loop insided?

Thank you for your quick reply.
I tried what you said and go the following error on the front-end:
<strong>Parse error: syntax error, unexpected T_IF in /home/piersru1/public_html/blog/wp-content/themes/grace/includes/postautothumbsoff.php on line 21</strong>
Regarding your questions: i have no answer because i am too ignorant of php.
If I understand correctly its concerning my category php. Here is the category php code:
<?php get_header();
if (have_posts()) : ?>
<div id="columnleft"> <!-- columnleft -->
<?php $post = $posts[0]; // Hack. Set $post so that the_date() works. ?>
<?php /* If this is a category archive */ if (is_category()) { ?>
<h2 class="pagetitle"><?php single_cat_title(); ?> Showcase</h2>
<p> <?php echo category_description( $category ); ?> <p>
<div class="sexy"><?php if(function_exists('selfserv_sexy')) { selfserv_sexy(); } ?></div>
<?php /* If this is a tag archive */ } elseif( is_tag() ) { ?>
<h2 class="pagetitle">Photos Tagged ‘<?php single_tag_title(); ?>’</h2>
<p>These are all of the photos tagged ‘<?php single_tag_title(); ?>’.</p>
<?php /* If this is a daily archive */ } elseif (is_day()) { ?>
<h2 class="pagetitle">Archive for <?php the_time('F jS, Y'); ?></h2>
<p>These are all of the photos from <?php the_time('F jS, Y'); ?>.</p>
<?php /* If this is a monthly archive */ } elseif (is_month()) { ?>
<h2 class="pagetitle">Archive for <?php the_time('F, Y'); ?></h2>
<p>These are all of the photos from <?php the_time('F, Y'); ?>.</p>
<?php /* If this is a yearly archive */ } elseif (is_year()) { ?>
<h2 class="pagetitle">Archive for <?php the_time('Y'); ?></h2>
<p>These are all of the photos from <?php the_time('Y'); ?>.</p>
<?php /* If this is an author archive */ } elseif (is_author()) { ?>
<h2 class="pagetitle">Author Archive</h2>
<p>These are all of the photos added by <?php the_author(); ?>.</p>
<?php /* If this is a paged archive */ } elseif (isset($_GET['paged']) && !empty($_GET['paged'])) { ?>
<h2 class="pagetitle"><?php bloginfo('name'); ?> Gallery Archives</h2>
<p>These are all of the photos from the <?php bloginfo('name'); ?> gallery archives.</p>
<?php } ?>
<p class="clearall"> </p>
</div> <!-- columnleft -->
<div id="columnright"> <!-- columnright -->
<ul id="latestworkgallery">
<?php $theme_options = get_option('Grace'); ?>
<?php if (!isset($theme_options["autothumb"]) || $theme_options["autothumb"] == "timthumbon") {
include (TEMPLATEPATH . '/includes/autothumbson.php');
}
else if (!isset($theme_options["autothumb"]) || $theme_options["autothumb"] == "timthumboff") {
include (TEMPLATEPATH . '/includes/autothumbsoff.php');
} ?>
</ul>
<div class="clearall"> </div>
<p class="postnavigation">
<?php next_posts_link('<span class="previouspostbutton"> </span>') ?> <?php previous_posts_link('<span class="nextpostbutton"> </span>') ?>
</p>
</div> <!-- columnright -->
<p class="clearall"> </p>
<?php endif; ?>
</div> <!-- content -->
<?php get_footer(); ?>

Does that help?
Oleg Butuzov comments:
let me check the category.php
meanwhile check the code at main answer witch relates to the (after var dumpsemicollon).i think you have cpy my code with error before i had change it.
Mathias Vagni comments:
btw. autothumbsoff.php and postautothumbsoff.php is the same file. I just duplicated it to be able to change the thumbnail generation on the single posts and the archives seperately.
I tried your code again and this time it showed the thumbnail as before but put this line directly above the thumbnail:
string(73) "http://piersrueb.com/blog/wp-content/uploads/2010/07/timthumb-2.php_1.png"
Mathias Vagni comments:
thank you for your help!
Oleg Butuzov comments:
And its show you this code only on single.php only?
Mathias Vagni comments:
yes. your latest code is online now.

Oleg Butuzov comments:
thanks. let me write you a code of new loop for single.php wait a 5 minutes. cheers
Oleg Butuzov comments:
can you insert my code
// its actualy array of the categories but we are taking only girst one
$cat = array_shift(get_the_category($post->ID));
$params = array(
'cat' => $cat->term_id,
'showposts' => 6,
);
//showposts related to the numebr of the posts that shoueld be displayed be runned
query_posts($params);
after this one (of your single.php)
<ul id="latestworkgallery">
Mathias Vagni comments:
check the link on previous post.
its showing it as text? is a php tag missing? sorry if this is a stupid question.
Mathias Vagni comments:
It now reads:
<h2>Featured</h2>
<ul id="latestworkgallery">
// its actualy array of the categories but we are taking only girst one
$cat = array_shift(get_the_category($post->ID));
$params = array(
'cat' => $cat->term_id,
'showposts' => 6,
);
//showposts related to the numebr of the posts that shoueld be displayed be runned
query_posts($params);
<?php $theme_options = get_option('Grace'); ?>
<?php if (!isset($theme_options["autothumb"]) || $theme_options["autothumb"] == "timthumbon") {
include (TEMPLATEPATH . '/includes/postautothumbson.php');
}
else if (!isset($theme_options["autothumb"]) || $theme_options["autothumb"] == "timthumboff") {
include (TEMPLATEPATH . '/includes/postautothumbsoff.php');
} ?>
</ul>
</div> <!-- columnright -->
Oleg Butuzov comments:
sorry.
you should wrap it by php tags
<?php
// its actualy array of the categories but we are taking only girst one
$cat = array_shift(get_the_category($post->ID));
$params = array(
'cat' => $cat->term_id,
'showposts' => 6,
);
//showposts related to the numebr of the posts that shoueld be displayed be runned
query_posts($params);
?>
// once again sorry, its normaly for me to write php code without php tags...
Mathias Vagni comments:
yes!
its working. nearly.
look at the link:[[LINK href="http://piersrueb.com/blog/archives/63"]]http://piersrueb.com/blog/archives/63[[/LINK]]
it now shows the url of the pic adn something with "string" above it.
