WordPress có chức năng cho chúng ta chọn hình ảnh bất kỳ nào đó để đặt làm hình đại diện cho bài viết! Bằng cách vào mục Featured Image.
Hôm nay mình xin chia sẻ cho các bạn một thủ thuật nhỏ, giúp lấy hình ảnh đầu tiên trong bài viết của mình làm hình đại diện. Mục đính của cách làm này là giúp bạn đỡ thời gian, và tiết kiệm băng thông cũng như dung lượng host.
Đầu tiên bản mở file functions.php nằm trong themes của bạn, sau đó chèn đoạn code sau vào giữa cặp thẻ <?php ?>.
PHP: 
/** Get The First Image From a Post **/
functioncatch_that_image() {
global$post,$posts;
$first_img='';
ob_start();
ob_end_clean();
$output= preg_match_all('/<img. src=[\'"]([^\'"] )[\'"].*>/i',$post->post_content,$matches);
$first_img=$matches[1][0];
if(empty($first_img)) {
$first_img= get_template_directory_uri()."/images/no_images.jpg";/** Hình ảnh mặc định khi trong bài viết không có bất kỳ hỉnh ảnh nào. **/
}
return$first_img;
}
Để sử dụng chúng ta chỉ cần chèn đoạn code sau vào nơi cần hiển thị:
PHP: 
<a href="<?php the_permalink(); ?>">
<?php
echo'<img src="'. catch_that_image() .'"/>';
?>
</a>
Đến đây là các bạn đã có hình ảnh đại diện bài viết như ý muốn mà lại không tốn thời gian cũng như dung lượng host.chúc bạn thành công.
