wordpress 特色图像功能

在主题的functions.php中添加如下代码

//使WordPress支持post thumbnail
if ( function_exists( 'add_theme_support' ) ) {
    add_theme_support( 'post-thumbnails' );
}

如何调用特色图像

<?php
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
    the_post_thumbnail();
}
?>
<?php the_content(); ?>

WordPress获取特色图像地址主要需要用到两个函数get_post_thumbnail_id和wp_get_attachment_image_src。下面是分别获取小、中、大、完整、指定图片规格的图片地址的方法。

获取特色图像：小

$thumbnail_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'thumbnail');
echo $thumbnail_image_url[0];

获取特色图像：中

$medium_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'medium');
echo $medium_image_url[0];

获取特色图像：大

$large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'large');
echo $large_image_url[0];

获取特色图像：完整

$full_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
echo $full_image_url[0];

获取特色图像：指定100×100

$array_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), array(100,100));
echo $array_image_url[0];
