如何通过wordpress中的字段过滤自定义帖子？

Question

好的，非常简单的任务，我只是不擅长PHP。

我有一个页面，我想列出一些使用样式列表的工作人员。这是网页 - http://www.themontessoripeople.co.uk/montesori/?post_type=people

我下载了一个“自定义内容类型”插件，并添加了“people”的内容类型并添加了相应的字段。现在我想筛选我通过名为“层次结构”的自定义字段添加的帖子。

这里是我想要的页面显示 - http://i47.tinypic.com/oqymwh.jpg

自定义字段“层次”既包含“管理”，“babies_room”和“toddlers_room”的房间变量。

如何修改下面的代码以过滤<?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; ?> 

谢谢，本。

这里是在参考了两套筛选结果的工作代码 -

<?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 -->

我已经简化你的代码。添加过滤器：

<?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); 
    } 
?> 

编辑：get_custom_field而不是print_custom_field。

您可以在query_posts($args)中定义查询参数 - 查看query_posts。也许你可以试试get_posts
