adding first image from post to front page spoiler

von Joern am 12. Aug. 2010 | Keine Kommentare

hi so i have done some modification to my index.php. on the frontpage the code i am using is the index.php from your website, where you select one post from each category to be displayed on the frontpage. what i am trying to do is pull the first image from a post and display it in the spoiler. i have a code that works but for some odd reason the pictures that are displayed are not the corresponding ones with the post. it’s like it’s almost offset by one post. if you would like i can give you a test account to see my theme since i am using theme test drive.
and here is the code i have

Code:


<!--- code to display one post per category only, put the category ID below in the order you wish and as many you want --->

<?php $display_categories = array(53,56,57,55,54); foreach ($display_categories as $frontcats) { ?>

<?php $catposts = get_posts("showposts=1&cat=$frontcats"); foreach($catposts as $post) : setup_postdata($post); ?>

<div class="clearfloat">

<h3 class=cat_title>"><?php $this_category = get_category($frontcats); ?><?php echo $this_category->cat_name; ?> »</h3>

<div class="title">" rel="bookmark"><?php the_title(); ?></div>

<div class="meta">[<?php the_time('j M Y') ?> | <?php comments_popup_link('No Comment', 'One Comment', '% Comments');?> | <?php if(function_exists('the_views')) { the_views(); } ?>]</div>

<div class="spoiler">

<?php   $values = get_post_custom_values("Image");if (isset($values[0])) { ?>

" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">

<img src="<?php echo bloginfo('template_url'); ?>/scripts/timthumb.php?src=/<?php

$values = get_post_custom_values("Image"); echo $values[0]; ?>&w=150&h=150&zc=1&q=100"

alt="<?php the_title(); ?>" class="left" width="150px" height="150px"  />

<?php }

else {

$id =$post->ID;

$the_content = $wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE ID = $id");

$home = get_option('home');

$pattern = '!<img.*?src="'.$home.'(.*?)"!';

$image_src = $matches['1'][0];

preg_match_all($pattern, $the_content, $matches);?>

<?php if($image_src != '') { ?><img src="<?php echo bloginfo('template_url'); ?>/scripts/timthumb.php?src=<?php echo $image_src; ?>&w=150&h=150&zc=1&q=100"

alt="<?php the_title(); ?>" class="left" width="150px" height="150px"  />

<?php } ?>

<?php } ?>

<?php the_excerpt(); ?>

</div>

</div>

<?php endforeach; // end of post ?>

<?php } ?>

<!--- end of code to display one post per category only --->

<?php } // end of FIRST PAGE ?>

thnx for your help and hope im clear on my question

looking at the code again I think you get the matches after preg_match so you could try this by putting "$image_src = ..." below preg_match_allThe line with the comment ($image_src = '';) might help, try without this line first....$the_content =…
