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

1. <?php

2. $thumbnail_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'thumbnail');

3. echo $thumbnail_image_url[0];

4. ?>

获取特色图像：中

1. <?php

2. $medium_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'medium');

3. echo $medium_image_url[0];

4. ?>

获取特色图像：大

1. <?php

2. $large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'large');

3. echo $large_image_url[0];

4. ?>

获取特色图像：完整

1. <?php

2. $full_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');

3. echo $full_image_url[0];

4. ?>

获取特色图像：指定 100×100

1. <?php

2. $array_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), array(100,100));

3. echo $array_image_url[0];

4. ?>
