displaying a post thumbnail depending on category in Wordpress?

本文关键字：略图显示 Wordpress 根据 | 更新日期: 2023-09-27

是否可以根据类别ID显示特定的帖子缩略图，如下所示：

<?php if ( has_post_thumbnail() ) {
      if ( cat = 2 ) {
      echo '<img src="image1.jpg" width="" height="" class="live-holder-img" />';
      } elseif( cat = 3 ) {
      echo '<img src="image2.jpg" width="" height="" class="live-holder-img" />';
      } else {
      echo '<img src="default.jpg" width="" height="" class="default" />'
      }
 ?>

您可能想查看类别模板： http://codex.wordpress.org/Category_Templates

快速的解决方案是这样的：

if (is_category('1')) {
    echo '<img src="image1.jpg" width="" height="" class="live-holder-img" />';
} else if (is_category('2')) {
    echo '<img src="image2.jpg" width="" height="" class="live-holder-img" />';
} else {
    echo '<img src="default.jpg" width="" height="" class="default" />';
}
//you can also do this by name
if (is_category('Category A')) {
    echo '<img src="image1.jpg" width="" height="" class="live-holder-img" />';
} else if (is_category('Category B')) {
    echo '<img src="image2.jpg" width="" height="" class="live-holder-img" />';
} else {
    echo '<img src="default.jpg" width="" height="" class="default" />';
}

is_category函数参考：http://codex.wordpress.org/Function_Reference/is_category
