在WordPress主题中除以零错误

我最近购买了一个WordPress主题,可以对照片进行精美的画廊展示,并且在主页上出现了以下错误。

警告:在第36行的/home/content/21/4913121/html/stsudios/wp-content/themes/dt-chocolate/front-gal.php中将其除以

警告:在第48行的/home/content/21/4913121/html/stsudios/wp-content/themes/dt-chocolate/front-gal.php中除以零

以下是第50行的代码 - /**/的行是麻烦的。任何帮助表示赞赏!

<?php

global $postgallery;
$show = $postgallery->get_post_option('show');
$arr = $postgallery->get_post_option('show_'.$show);
$arr = explode(",", $arr);
$arr = (array)$arr;

//$myterms = get_terms('dt_gallery_cat');
$myterms = apply_filters( 'taxonomy-images-get-terms', '', array('taxonomy'=> 'dt_gallery_cat'));

$images = array();

global $term, $h;

foreach ($myterms as $term)
{

   if ($show == "all")
   {

   }
   elseif ($show == "only")
   {
      if ( !in_array( $term->term_id, $arr ) )
         continue;
   }
   elseif ($show == "except")
   {
      if ( in_array( $term->term_id, $arr ) )
         continue;
   }

   $term->pic = wp_get_attachment_image_src( $term->image_id, 'full' );

   $k = $term->pic[1] / $term->pic[2];

   /**/$term->pic = $term->pic[0];/**/

   $size = taxonomy_get_size( $term->term_id );
   if ($size == "s")
      $w = 220;
   if ($size == "m")
      $w = 460;
   if ($size == "l")
      $w = 700;

   /**/$h = ceil($w / $k);/**/

   $term->pic = get_template_directory_uri().'/thumb.php?src='.$term->pic.'&amp;w='.$w.'&amp;h='.$h.'&amp;zc=1';

答案 0 :(得分:2)

如果您添加一些代码来检查值是否为零,则应该停止执行此操作,但可能存在更大的问题。

if ( $term->pic[1] == 0 || $term->pic[2] == 0 ) return

和/或

$h = ( $w > 0 && $k > 0 ) ? ceil($w / $k) : 0;

这些值可能不应该为零,因此可能会出现其他问题。也许您的图片不是代码可读的格式......或者您尚未上传任何
