原标题:Filter posts in slider

我的餐厅(3Slider JQuery)打电话,显示最后5个员额。 它从一个称为umb的习俗领域收集图像。

相反,我喜欢把那些在umb本习俗领域具有价值的图像只打上。 这是可能的吗?

现 问 题

<?php
$my_query = new WP_Query( showposts=5 );
while ($my_query->have_posts()) : $my_query->the_post();
?>
<li class="sliderImage"> <a href="<?php the_permalink() ?>" rel="bookmark"> <img class="featimg" src="<?php echo get_post_meta($post->ID,  thumb , true) ?>" alt="<?php the_title(); ?>"  />
<span class="des"><h1><?php the_title(); ?></h1><?php the_excerpt(); ?></span>    
</a>
</li>
<?php endwhile; ?>

提前感谢。

问题回答

你会想将贵重的WP_Query改为:

$my_query = new WP_Query(
    array(
         posts_per_page  =>  5 ,
         meta_query  => array(
            array(
                 key  =>  thumb ,
                 value  =>   ,
                 compare  =>  != 
            )
        )
    )
);

当然,如果某人进入了一种价值,即没有一条有效的图像途径(例如,blahblah),这仍会传递给您的<代码><img> 载于您的<代码><li>要素,因此,你可能想在处理压力背书人的意见时做一些进一步的检查/处理。
