我有以下代码,由于某种原因,该代码会导致无限循环.有人可以解释发生了什么吗?

谢谢！

 <?php 

$flagged_stores = new WP_Query( array ( 'post_type' => 'store', 'orderby' => 'post_id', 'meta_key' => 'flagged', 'limit' => 10 ) );

   if($flagged_stores->have_posts()): ?> 
        <div class="table">
            <table class="form-table">
                <tr>
                    <th>Store</th>
                    <th>Flag Reason</th>
                    <th>Delete Flag</th>
                </tr>
                <?php while($flagged_stores->have_posts()): ?>
                    <td><?php echo the_title(); ?></td>
                    <td><?php// echo get_post_custom_values('flagged'); ?></td>
                    <td><?php// echo "Delete"; ?></td>
                <?php endwhile;?>
            </table>
    <?php else: ?>
            No flags found.
    <?php endif; ?>

I have the following code, which causes an infinite loop for some reason. Can anybody explain what's going on please?

Thanks!

<?php 

$flagged_stores = new WP_Query( array ( 'post_type' => 'store', 'orderby' => 'post_id', 'meta_key' => 'flagged', 'limit' => 10 ) );

   if($flagged_stores->have_posts()): ?> 
        <div class="table">
            <table class="form-table">
                <tr>
                    <th>Store</th>
                    <th>Flag Reason</th>
                    <th>Delete Flag</th>
                </tr>
                <?php while($flagged_stores->have_posts()): ?>
                    <td><?php echo the_title(); ?></td>
                    <td><?php// echo get_post_custom_values('flagged'); ?></td>
                    <td><?php// echo "Delete"; ?></td>
                <?php endwhile;?>
            </table>
    <?php else: ?>
            No flags found.
    <?php endif; ?>

看看这个答案:按标签获取自定义帖子类型

我相信您会在$flagged_stores->the_post()循环内使用while.

+1-被发现；它确实应该显示为:` have_posts()):$flagged_stores->the_post();?>`-@yuval:无限循环是否总是显示相同的标题?

+1 - well spotted; it should indeed read: `have_posts()): $flagged_stores->the_post(); ?>` - @yuval: did the endless loop always show the same title?

@Michael是的,因为没有[`the_post()`](http://codex.wordpress.org/Function_Reference/the_post),您就不会逐个查找帖子

@Michael yes, because you don't seek post by post without [`the_post()`](http://codex.wordpress.org/Function_Reference/the_post)

也不要执行"echothe_title()",只是"the_title()",因为它默认情况下会自行打印.通常,您将`echo`与以get_开头的函数一起使用,例如在`echoget_the_title()`中

Also don't do `echo the_title()` it's just `the_title()`, as it prints itself by default. Usually you use `echo` with functions starting with get_, like in `echo get_the_title()`

尝试并使用'posts_per_page'而不是'limit'- http://codex.wordpress.org/Class_Reference/WP_Query#Parameters

仍然没有运气.还有其他想法吗?谢谢！

Still no luck. Any other ideas? Thanks!

我不知道这是引起无限循环的原因,但是您的WP_Query已关闭.

 $flagged_stores = new WP_Query( array ( 'post_type' => 'store', 'orderby' => 'ID', 'meta_key' => 'flagged', 'posts_per_page' => 10 ) );

我更新了'orderby'和'posts_per_page'.

I do not know if this is what caused the infinite loop, but your WP_Query is off.

$flagged_stores = new WP_Query( array ( 'post_type' => 'store', 'orderby' => 'ID', 'meta_key' => 'flagged', 'posts_per_page' => 10 ) );

I updated 'orderby' and 'posts_per_page'.
