这是带有输出的 PHP 代码:
<?php wp_reset_query();?><?php$post_name = $post->post_name;if ($post_name == "17u-navy") {$post_type = "17u_navy";}elseif ($post_name == "15u-navy") {$post_type = "15u_navy";}elseif ($post_name == "17u-red") {$post_type = "17u_red";}elseif ($post_name == "17u-white") {$post_type = "17u_white";}elseif ($post_name == "17u-gold") {$post_type = "17u_gold";}$args = array('post_type'=>$post_type,'posts_per_page'=>-1, 'orderby' => 'number', 'order' => 'ASC',);$the_query = new WP_Query( $args );$标志= 0;如果 ($the_query->have_posts()):?><?php while ($the_query->have_posts()): $the_query->the_post();?><?php$flag++;?><?php if ($flag == 999): ?><?php $flag = 0;?><?php endif;?><h3 class="h-custom-headline cs-ta-left h4 口音"><span><?php the_title();?> #<?php the_field('number');?></span></h3><div id="x-section-2" class="x-section" style="margin: 0px 0px 25px 0px;padding: 0px; background-color: transparent; margin-bottom: 50px;"><div class="x-column x-sm x-1-5" style="padding: 0px;"><img class="x-img x-img-none" src="<?php the_field('profilephoto'); ?>"><div class="x-column x-sm x-4-5" style="padding: 0px;"><ul class="x-block-grid two-up"><li class="x-block-grid-item"><strong><?php the_field('gradyear');的类?></strong><br/><strong>高度:</strong><?php the_field('height');?><br/><strong>职位:</strong><?php the_field('位置');?><br/><?php if(get_field('bballhonors')): ?><strong>篮球荣誉:</strong><?php the_field('bballhonors');?><br/><?php endif;?><?php if(get_field('ncaaclearing')): ?><strong>NCAA 清算所:</strong><?php the_field('ncaaclearing');?><br/><?php endif;?><?php if(get_field('highlightfilm')): ?><strong>亮点影片:</strong><a href="<?php the_field('highlightfilm'); ?>"target="_blank">link</a><?php endif;?><?php if(get_field('hobbies')): ?><strong>爱好:</strong><?php the_field('爱好');?><?php endif;?><li class="x-block-grid-item"><strong>高中:</strong><?php the_field('highschool');?><br/><strong>家乡:</strong><?php the_field('citystate');?><br/><?php if(get_field('gpa')): ?><strong>GPA:</strong><?php the_field('gpa');?><br/><?php endif;?><?php if(get_field('sat')): ?><strong>SAT:</strong><?php the_field('sat');?><br/><?php endif;?><?php if( get_field('schoolhonors') ): ?><strong>学校荣誉:</strong><?php the_field('schoolhonors');?><br/><?php endif;?><?php if( get_field('favoritequote') ): ?><strong>最喜欢的引用:</strong><em><br/>"<?php the_field('favoritequote');?>"</em><br/><?php if(get_field('author')): ?>~ <?php the_field('author');?><?php endif;?><?php endif;?></li>
<?php endwhile;?><?php endif;?>
您尝试做的事情看起来很简单，使用正确的工具非常简单，但是尝试做一些事情，例如提取 Jersey Number 然后订购那个帖子会留下一团糟的WP_Query，这只是一个可怕的想法.
就后序而言，有几种方法可以作弊".
您可以获得一个插件，让您可以创建自定义发布订单，但这会破坏通过 WP_Query 的排序并锁定"它，因此我总是尽可能避免这种情况.
您可以获得一个名为高级自定义字段"的插件并创建一个新字段，您将在其中写入帖子的 Jersey 编号，然后按该字段对查询进行排序，这可能是最好的方法.
我还喜欢创建一个无限制的转发器字段，它允许我为每个重复字段选择一个帖子，并按照我想要的任何顺序一个接一个地添加帖子 - 这会改变您构建查询和模板的方式，因此它是稍微复杂一点.
(而且一开始的 ifs 链看起来很可怕.它会导致以后管理方面的痛苦.我希望我可以编写模板并对其进行测试:( )
I'm trying to order this roster by Jersey Number but haven't been able to make it work. I'm not a programmer and have searched and tried to make this work multiple times.
Thank you so much for any help.

What you're trying to do seems simple, and with the right tools is very simple, but trying to do something like extract the Jersey Number and then order the posts by that is going to leave a mess of a WP_Query and is just a horrible idea.
There's a few ways to 'cheat' in terms of post order.
You could get a plugin that allows you to create a custom post order, but this breaks the ordering via WP_Query and 'locks' it, so I always avoid that when I can.
You could get a plugin called 'Advanced Custom Fields' and create a new field where you will write Jersey number of the post, then order the query by that field, which is probably the best way to do it.
I also like to create an unlimited repeater field that will allow me to choose a single post per repeated field and keep adding posts one by one in whatever order I want - this changes the way you structure the query and the template so it's a little bit more complex.
(also that chain of ifs at the beginning is horrible to look at. It's going to lead to pain in terms of management later on. I wish I could just write the template and test it :( )
