help with custom field data

    hello, hope someone here can help me.

    i would like to do two things, and both require ‘getting’ information from a page / its custom field data, and inserting into another code.

    first: in my category.php file, before calling up all posts from a specific category, i’d like to insert code that would call up the content from a page with the same name as the category name.

    for example, for a category named ‘The Beatles’ i’d like to pull up the_content from a page also named ‘The Beatles’ and include it in the category

    if i could get this to work, this second part won’t be as important, however i’d still like to know how to do it…

    second, on a page i’d like to call up all posts from a specific category. the category id would be specified as a value from a custom field entry from that page.

    i’ve used get_posts to pull up the posts, and get_post_meta to pull up the custom field data, however when i use them together like this, it gives me an error:

    <?php
 $postslist = get_posts('numberposts=5&order=DESC&orderby=ID&category=<?php echo get_post_meta($post->ID, 'identity', true); ?>');
 foreach ($postslist as $post) :
    setup_postdata($post);
 ?>
 <div class="recent">
 <?php the_excerpt(); ?>
 <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
 </div>
 <?php endforeach; ?>

    kind of new to more ‘complex’ use of this code so any help is greatly appreciated!

  • first question:

    <?php
$current_cat_name = single_cat_title('',false);
$page = get_page_by_title($current_cat_name);
if($page) : //only do the following if a page with this title exists
$pageid=$page->ID;
query_posts('post_status=publish&page_id='.$pageid);
if(have_posts()) : while(have_posts()) : the_post();
/*your page output code here*/
the_title();
the_content();
endwhile;
endif; //end of the loop
wp_reset_query();
endif; //end of if($page)
?>

    second question:
    you seem to have ignored the sequence of opening/closing php tags:
    instead of this line:

    $postslist = get_posts('numberposts=5&order=DESC&orderby=ID&category=<?php echo get_post_meta($post->ID, 'identity', true); ?>');

    you could try to use:

    $postslist = get_posts('numberposts=5&order=DESC&orderby=ID&category='. get_post_meta($post->ID, 'identity', true));

    actually, for the first code, how about calling up just a link to the page with the same title, rather than the content from that page?

    i’d like to insert code that would call up the content from a page with the same name as the category name.

    it is not absolutely clear to me what that means;
    however, if you just want to have a link to that particular page there:

    <?php
$current_cat_name = single_cat_title('',false);
$page = get_page_by_title($current_cat_name);
if($page) : //only do the following if a page with this title exists
$pageid=$page->ID; ?>
<a href="<?php echo get_permalink($pageid);?>"><?php echo $page->post_title; ?></a>
<?php
endif;
?>

    this outputs the linked title of the page with the same name as the category.
