将循环输出保存到变量中

问题描述：

I have a loop to get a list of terms for a taxonomy.

    <?php 
  $terms = get_field('modell');
  if( $terms ):
    $total = count($terms);
    $count = 1;
    foreach( $terms as $term ):
      ?>
      '<?php echo $term->slug; ?>'
      <?php 
      if ($count < $total) {
        echo ', ';
      }
      $count++;
    endforeach;
  endif; 
?>

The loop output is this:

 'termname-one','termname-two','termname-three'

Now I want to save this output into variable ($termoutput) and insert it into a array of terms of following loop:

<?php 
query_posts( array(  
    'post_type' => 'posttypename', 
    'posts_per_page' => -1, 
    'orderby' => 'title',
    'order' => 'ASC',
    'tax_query' => array( 
       array( 
          'taxonomy' => 'systems', 
          'field' => 'slug', 
         'terms' => array($termoutput)
       ) 
   ) 

) );    ?>

Is there a way to achive this? Thank you!

我有一个循环来获取分类法的术语列表。 p>

 ＆lt;？php 
 $ terms = get_field（'modell'）; 
 if（$ terms）：
 $ total = count（$ terms）; \  n $ count = 1; 
 foreach（$ terms as $ term）：
？＆gt; 
'＆lt;？php echo $ term-＆gt; slug;  ？＆gt;'
＆lt;？php 
 if（$ count＆lt; $ total）{
 echo'，'; 
} 
 $ count ++; 
 endforeach; 
 endif;  
？＆gt; 
  code>  pre> 
 
 循环输出为： p> 
 
 
 'termname-one'，'termname  -two'，'termname-three'
  code>  pre> 
 
 现在我想将此输出保存到变量（ $ termoutput  strong>）并将其插入 以下循环的术语数组： p> 
 
 
 ＆lt;？php 
query_posts（array（
'post_type'=＆gt;'posttypename'，
'posrs_per_page'=＆gt;  ; -1，
'orderby'=＆gt;'title'，
'order'=＆gt;'ASC'，
'tax_query'=＆gt;数组（
 array（
'taxonomy'=＆gt;  'systems'，
'field'=＆gt;'slug'，
'terms'=＆gt; array（$ termoutput）
）
）
 
））;  ？＆gt; 
  code>  pre> 
 
 有没有办法实现这个目标？ 谢谢！ p>

答

You should accumulate your output into an array like this:

$termoutput = array();

...

foreach( $terms as $term ) {
    $termoutput[] = $term->slug;
}

Then, in the second section of your code:

...
'terms' => $termoutput

Try this:

 <?php 
  $terms = get_field('modell');
  if( $terms ):
    $total = count($terms);
    $count = 1;
    $termoutput = array();
    foreach( $terms as $term ):

      echo "'".$term->slug."'"; 
      $termoutput[] = $term->slug;

      if ($count < $total) {
        echo ', ';
      }
      $count++;
    endforeach;
  endif; 
?>


<?php 
    query_posts( array(  
        'post_type' => 'posttypename', 
        'posts_per_page' => -1, 
        'orderby' => 'title',
        'order' => 'ASC',
        'tax_query' => array( 
          array( 
              'taxonomy' => 'systems', 
              'field' => 'slug', 
             'terms' => $termoutput
           ) 
       ) 

    ) );    
 ?>

This will store $term->slug to $termoutput[] as an array.
