PHP foreach loop & html table - displaying duplicates

问题

以下是您要翻译的内容：

"我正在使用WordPress、ACF和PHP；我已经创建了一个自定义块，代码如下。请让我知道是否需要更多信息。我对此还相当新手，不确定需要包括哪些内容。

我能够弄清楚。我在foreach($progcode_check_checked_values as $progcode_check_value)之后添加了一个if语句。我也能够让被注释的$code = get_sub_field('discipline_code')正常工作。下面是更新后的代码。

  1. <table style="width: 800px;">
  2.     <thead>
  3.         <tr>
  4.             <th>Course</th>

  6.             <th>Course Credits</th>
  7.         </tr>
  8.     </thead>

  14.         $i = 0;
  16.         foreach($rawcourses as $rawcourse) : 
  17.             if( have_rows('course_list', $rawcourse) ): ?>
  19.             <?php

  21.                 $code = get_sub_field('discipline_code');

I was able to figure out. I added an if statement after the foreach($progcode_check_checked_values as $progcode_check_value). I was able to get the commented out $code = get_sub_field('discipline_code') to work as well. Updated code below.

  1. &lt;table style=&quot;width: 800px;&quot;&gt;
  2. &lt;thead&gt;
  3. &lt;tr&gt;
  4. &lt;th&gt;Course&lt;/th&gt;
  5. &lt;th&gt;Course Name&lt;/th&gt;
  6. &lt;th&gt;Course Credits&lt;/th&gt;
  7. &lt;/tr&gt;
  8. &lt;/thead&gt;
  9. &lt;tbody&gt;
  10. &lt;?php 
  11. $rawcourses = get_field(&#39;course_selector&#39;); 
  12. $progcode_check_checked_values = get_field(&#39;prog_discipline_code&#39;); 
  13. $i = 0;
  14. foreach($rawcourses as $rawcourse) : 
  15. if( have_rows(&#39;course_list&#39;, $rawcourse) ): ?&gt;
  16. &lt;?php
  17. while( have_rows(&#39;course_list&#39;, $rawcourse) ) : the_row(); 
  18. $code = get_sub_field(&#39;discipline_code&#39;);
  19. if ($progcode_check_checked_values) : ?&gt;
  20. &lt;?php foreach ($progcode_check_checked_values as $progcode_check_value) : ?&gt;
  21. &lt;?php if ($progcode_check_value == $code ) : ?&gt;

  23. &lt;td&gt;&lt;a href=&quot;#&quot; data-bs-toggle=&quot;modal&quot; data-bs-target=&quot;#modal&lt;?php get_sub_field(&#39;course_number&#39;);?&gt;&lt;?php echo $i;?&gt;&quot;&gt;&lt;?php echo strtoupper($progcode_check_value) ?&gt;&lt;?php the_sub_field(&#39;course_number&#39;); ?&gt;&lt;/a&gt;  &lt;/td&gt;
  24. &lt;td&gt;&lt;?php echo get_the_title($rawcourse); ?&gt; &lt;/td&gt;
  25. &lt;td&gt;&lt;?php the_sub_field(&#39;credits&#39;); ?&gt;&lt;/td&gt;

  27. &lt;div class=&quot;modal-dialog&quot;&gt;
  28. &lt;div class=&quot;modal-content&quot;&gt;
  29. &lt;div class=&quot;modal-header&quot;&gt;
  30. &lt;h5 class=&quot;modal-title&quot; id=&quot;exampleModalLabel&quot;&gt;&lt;?php echo get_the_title($rawcourse); ?&gt;&lt;/h5&gt;
  31. &lt;button type=&quot;button&quot; class=&quot;btn-close&quot; data-bs-dismiss=&quot;modal&quot; aria-label=&quot;Close&quot;&gt;&lt;/button&gt;
  32. &lt;/div&gt;
  33. &lt;div class=&quot;modal-body&quot;&gt;
  34. &lt;?php $content_post = get_post($rawcourse);
  35. $content = $content_post-&gt;post_content;

  38. echo $content; ?&gt;
  39. &lt;/div&gt;
  40. &lt;div class=&quot;modal-footer&quot;&gt;
  41. &lt;button type=&quot;button&quot; class=&quot;btn btn-secondary&quot; data-bs-dismiss=&quot;modal&quot;&gt;Close&lt;/button&gt;
  42. &lt;/div&gt;
  43. &lt;/div&gt;
  44. &lt;/div&gt;
  45. &lt;/div&gt;
  46. &lt;/tr&gt;
  47. &lt;?php endif; ?&gt;
