Question

使用无限滚动我尝试一次加载3个帖子，但只填写有特定字段（视频）的帖子。

例如，我最近的2个帖子填写了字段（视频），3d帖子没有，第4个帖子有。我想要帖子1,2和＆amp; 4加载的原因使得3.然后无限滚动应该加载包括视频等的接下来的3个帖子

无限滚动有效，分页查询有效，但是：因为帖子3没有填写视频字段，无限滚动只加载帖子1＆amp; 2并没有添加帖子4来完成我想要的3个帖子......

我的代码：

<div id="interviews">

<?php   $temp = $wp_query;
        $wp_query= null;
        $wp_query = new WP_Query();
        $wp_query->query('paged='.$paged.'&cat=5&showposts=3');
        while ($wp_query->have_posts()) : $wp_query->the_post();
        echo ('<ul id="infinite">');

    if (get('video_video', 1, TRUE)) {

        echo ('<li class="video">');
        $home = array("h" => 290, "w" => 380, "zc" => 1, "q" =>100);
        //echo get('video_video');
        echo ('With: ');
        echo get('participant_first_name');
        echo ('&nbsp;');
        echo get('participant_last_name');
        echo ('</li>');

        }else{ $video_video=false;
        echo ('');

         }  ?>

        <?php endwhile;?>
       </ul> 

<?php if ($wp_query->max_num_pages > 1) : ?>
<nav id="nav-below">
    <div class="nav-previous"><?php next_posts_link( __( '&larr; More', 'intowntheme' ) ); ?></div>
</nav>

<?php endif; ?>


</div><!--End interviews-->

Jquery脚本：

 jQuery('#interviews').infinitescroll({ 
navSelector  : "#nav-below",  // selector for the paged navigation (it will be hidden)
nextSelector : "#nav-below .nav-previous a",   // selector for the NEXT link (to page 2)
itemSelector : "li.video",  // selector for all items you'll retrieve
extraScrollPx: 50,    
loading         : {
     msgText: "<em>Loading the next year of Grantees...</em>",
    finishedMsg: "<em>You've reached the end of the Grantees.</em>"
}

}）;

Answer 1

之前我没见过get功能。你知道它从哪个表中提取数据吗？如果是wp_postmeta，您可以在WP_Query中使用custom field parameters来仅从数据库中检索您感兴趣的记录。

类似的东西：

$wp_query = new WP_Query();
$wp_query->query('paged='.$paged.'&cat=5&showposts=3&meta_key=video_video&meta_value=1');

应该这样做。

Answer 2

<div id="interviews">
<?php echo ('<ul id="infinite">'); ?>
<?php 
$wp_query = new WP_Query();
$wp_query->query('paged='.$paged.'&cat=5&showposts=3&meta_key=video_video&orderby=meta_value&order=ASC'  . $post->ID);
while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<?php if ( get_post_meta($post->ID, 'video_video', true) ) : ?>
    <li class="video"><?php $home = array("h" => 290, "w" => 380, "zc" => 1, "q" =>100);
            //echo get('video_video');
            echo ('With: ');
            echo get('participant_first_name');
            echo ('&nbsp;');
            echo get('participant_last_name');
            echo ('</li>');?>

<?php endif;?>


<?php endwhile;?>

<?php if (get_post_meta($post->ID, 'video_video', true) ) { ?>
    <?php if ($wp_query->max_num_pages > 1) : ?>
        <nav id="nav-below" >
        <div id="next"><?php next_posts_link( __( 'Scroll down for more', 'intowntheme' ) ); ?></div>
    </nav>
    <?php endif; //end nav ?>
<?php } else {  ?>
<p>There are no interviews at the moment </p>
<?php }   ?>     
</ul>     
</div><!--End interviews-->

使用if / else语句进行无限滚动
