Support » Fixing WordPress » exclude from wp_list_pages with meta_value

  • Can we exclude pages from wp_list_pages using met_key and meta_value?

    Does wordpress offer offer a way to do this?

    Or do I need to build an array manually? If so, what’s the cleanest way to do this? To subtract one array (list by meta_value) from the full list?

    thanks!!

  • Didn’t test this but something like this to get pages where custom field cf1 is equal to green:

    <?php
    $args=array(
      'showposts' => -1,
      'post_type' => 'page',
      'meta_key' => 'cf1',
      'meta_compare' => '=',
      'meta_value' => 'green'
    );
    $pages = get_posts($args);
    if ($pages) {
      foreach($pages as $post) {
        setup_postdata($post); ?>
        <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
        <?php
      } // foreach($pages
    } // if ($pages
    ?>

    Can anyone think of a better method?

    $list_full = wp_list_pages(‘echo=0’);
    $list_exclude = wp_list_pages(‘meta_value=XYZ&meta_key=ABC&echo=0’);
    $the_list = array_diff($list_full, $list_exclude);

    Thanks Michael. I’m looking to exclude items with meta_value green.

    What does meta_compare do? Can I set that to be not equal and use it with wp_list_pages?

    (I want to use wp_list_pages to utilize the class and hierarchy generated by WP)

    thanks again…

    So it seems like this will do the trick. I hadn’t seen meta_compare before.

    <?php

    $args = array(
    ‘meta_compare’ => ‘!=’,
    ‘meta_key’ => ‘Exclude_Page’,
    ‘meta_value’ => ‘Yes_Sir’,
    );

    wp_list_pages( $args );

    ?>

    wp_list_pages exclude is based on page ID and I just don’t see how you could relate that to a meta value.

    http://codex.wordpress.org/Template_Tags/wp_list_pages#Exclude_Pages_from_List

    Oh well, doesn’t work. I guess that meta_compare can’t be passed to wp_list_pages. that’s stinky. Back to the drawing board…

    Build an array of post ids using the get_posts example then use that array with the wp_list_pages exclude argument.

    You can use..

    <?php
    wp_list_pages( array('meta_key'=>'keyname','meta_value'=>'value') );
    ?>

    However you can’t use meta_compare when using wp_list_pages as it only supports both meta_key and meta_value, but not meta_compare..
    http://codex.wordpress.org/Function_Reference/get_pages

    get_posts is not documented as supporting meta_compare, but does look to support it(wp-includes/query.php – line 2146).

    Use get_posts if you need the meta_compare parameter, as Michael suggested.

    I believe that get_posts can use almost any argument listed in the query_posts() article.

    Hi,

    I’m trying something similar – exclude pages which don’t have the key/value of notmobile/notmobile.

    I’ve tried loads of different ways, and just used MichaelH’s code above to come up with:

    <?php
    global $post;
    $args=array(
      'post_type' => 'page',
      'meta_key' => 'notmobile',
      'meta_compare' => '!=',
      'meta_value' => 'notmobile'
    );
    $pages = get_posts($args); ?> 
    
    <ul>
       <?php wp_list_pages('exclude'.$pages); ?>
    </ul>

    But it doesn’t exclude the pages 🙁

    Any help would be sooo great!

    Thanks!

    Will repeat from above:

    sorry to show up my limited knowledge, but I thought that’s what I did??

    <?php
    global $post;
    $args=array(
      'post_type' => 'page',
      'meta_key' => 'notmobile',
      'meta_compare' => '!=',
      'meta_value' => 'notmobile'
    );
    $pages = get_posts($args);
    if ($pages) {
      $pageids = array();
      foreach ($pages as $page) {
        $pageids[]= $page->ID;
      }
    }
    ?>
    <ul>
       <?php wp_list_pages('exclude='.implode(",", $pageids)); ?>
    </ul>

    I really appreciate you coming back so quickly on this. Unfortunately I get an error:

    Warning: implode() [function.implode]: Invalid arguments passed in myurl/wp-content/themes/combined/desk_index.php on line 77

    Line 77 being:
    <?php wp_list_pages('exclude='.implode(",", $pageids)); ?>

    This is beyond me to even guess…

    Oops sorry, forgot to handle the situation where it finds NO pages with that meta_key/meta_compare/meta_value criteria:

    <?php
    global $post;
    $args=array(
      'post_type' => 'page',
      'meta_key' => 'notmobile',
      'meta_compare' => '!=',
      'meta_value' => 'notmobile'
    );
    $pages = get_posts($args);
    if ($pages) {
      $pageids = array();
      foreach ($pages as $page) {
        $pageids[]= $page->ID;
      }
     ?>
      <ul>
       <?php wp_list_pages('exclude='.implode(",", $pageids)); ?>
    </ul>
    <?php
    }
    ?>
