WordPress 獲取文章內容頁特色圖像地址

WordPress獲取特色圖像地址主要需要用到兩個函數get_post_thumbnail_id和wp_get_attachment_image_src。下面是分別獲取小、中、大、完整、指定圖片規格的圖片地址的方法

獲取特色圖像：小

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

獲取特色圖像：中

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

獲取特色圖像：大

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

獲取特色圖像：完整

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

獲取特色圖像：指定100x100

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