如何通過wordpress中的字段過濾自定義帖子？

Question

好的，非常簡單的任務，我只是不擅長PHP。

我有一個頁面，我想列出一些使用樣式列表的工作人員。這是網頁 - http://www.themontessoripeople.co.uk/montesori/?post_type=people

我下載了一個「自定義內容類型」插件，並添加了「people」的內容類型並添加了相應的字段。現在我想篩選我通過名爲「層次結構」的自定義字段添加的帖子。

這裏是我想要的頁面顯示 - http://i47.tinypic.com/oqymwh.jpg

自定義字段「層次」既包含「管理」，「babies_room」和「toddlers_room」的房間變量。

如何修改下面的代碼以過濾<?php print_custom_field('hierarchy'); ?>中保存的值？

<?php $col = 1; ?>  
    <?php if (have_posts()) : ?>   
     <?php while (have_posts()) : the_post(); ?>   
      <?php if ($col == 1) echo "<div class=\"row\">"; ?> 

       <div class="post col<?php echo $col;?>" id="post-<?php the_ID(); ?>"> 

          <div class="people-spacer"> 

           <div class="people"><a class="animate" > 
           <div class="bio"> 
           <p class="titles"><?php the_title(); ?><br/> 
           <span class="job"> <?php print_custom_field('job'); ?></span> </p><br /> 
           </div> 
           <img src="<?php print_custom_field('staff_image:to_image_src'); ?>" width="160" height="160" alt="<?php the_title(); ?>-image" /> 
           </div> 
           <div class="people-link-edit"><?php edit_post_link('Edit Post', ''); ?></div> 
          </div> 
       </div> 

      <?php if ($col == 1) echo "</div>"; (($col==1) ? $col=2 : $col=2); ?> 
     <?php endwhile; ?> 

謝謝，本。

這裏是在參考了兩套篩選結果的工作代碼 -

<?php $col = 1; ?> 
<?php if (have_posts()) : ?> 


<div class="text-box"> 

<h2>Management</h2> 
<?php while (have_posts()) : the_post(); ?> 
<?php if (get_custom_field('hierarchy') != "management") continue; ?> 

<?php if ($col == 1) echo "<div class=\"row\">"; ?> 
<div class="post col<?php echo $col;?>" id="post-<?php the_ID(); ?>"> 
<div class="people-spacer"> 
    <div class="people"><a class="animate" > 
    <div class="bio"> 
    <p class="titles"> 
    <?php the_title(); ?> 
    <br/> 
    <span class="job"> <?php print_custom_field('job'); ?></span> </p> 
    <br /> 
    </div> 
    <img src="<?php print_custom_field('staff_image:to_image_src'); ?>" width="160" height="160" alt="<?php the_title(); ?>-image" /> </div> 
    <div class="people-link-edit"> 
    <?php edit_post_link('Edit Post', ''); ?> 
    </div> 
</div> 
</div> 
<?php if ($col == 1) echo "</div>"; (($col==1) ? $col=2 : $col=2); ?> 
<?php endwhile; ?> 

</div><!-- close text box --> 


<div class="text-box"> 

<h2>Babies Room</h2> 

<?php while (have_posts()) : the_post(); ?> 
<?php if (get_custom_field('hierarchy') != "babies_room") continue; ?> 

<?php if ($col == 1) echo "<div class=\"row\">"; ?> 
<div class="post col<?php echo $col;?>" id="post-<?php the_ID(); ?>"> 
<div class="people-spacer"> 
    <div class="people"><a class="animate" > 
    <div class="bio"> 
    <p class="titles"> 
    <?php the_title(); ?> 
    <br/> 
    <span class="job"> <?php print_custom_field('job'); ?></span> </p> 
    <br /> 
    </div> 
    <img src="<?php print_custom_field('staff_image:to_image_src'); ?>" width="160" height="160" alt="<?php the_title(); ?>-image" /> </div> 
    <div class="people-link-edit"> 
    <?php edit_post_link('Edit Post', ''); ?> 
    </div> 
</div> 
</div> 
<?php if ($col == 1) echo "</div>"; (($col==1) ? $col=2 : $col=2); ?> 
<?php endwhile; ?> 

</div><!-- close text box -->

我已經簡化你的代碼。添加過濾器：

<?php 
    $col = 1; 
    while (have_posts()) 
    { 
     the_post(); 
     if ($col == 1) echo "<div class=\"row\">"; 

     // filter 
     $hierarchy = get_custom_field('hierarchy'); 
     // if it does not match continue (skip) 
     if ($hierarchy != "boss") continue; 
     // if it matches continue (skip) 
     //if ($hierarchy == "notboss") continue; 

     // needed fields 
     $id = the_ID(); 
     $job = get_custom_field('job'); 
     $title = the_title(); 
     $img = get_custom_field('staff_image:to_image_src'); 
     $edit = edit_post_link('Edit Post', ''); 

     echo <<< END 
       <div class="post col$col" id="post-$id"> 
        <div class="people-spacer"> 
         <div class="people"><a class="animate" > 
         <div class="bio"> 
         <p class="titles">$title<br/> 
         <span class="job">$job</span> </p><br /> 
         </div> 
         <img src="$img" width="160" height="160" alt="$title-image" /> 
         </div> 
         <div class="people-link-edit">$edit</div> 
        </div> 
       </div> 
END; 

     if ($col == 1) echo "</div>"; 
     (($col==1) ? $col=2 : $col=2); 
    } 
?> 

編輯：get_custom_field而不是print_custom_field。

您可以在query_posts($args)中定義查詢參數 - 查看query_posts。也許你可以試試get_posts
