WordPress获取文章所有图片和图片数量

如果想用WordPress做成图片站或者CMS，主页可能需要获取文章所有图片，那么如何实现呢？下面教大家WordPress获取文章所有图片和数量方法：

wordpress主题获取文章中的所有图片

function hui_get_thumbnail( $single=true, $must=true ) { global $post; $html = ''; if ( has_post_thumbnail() ) { $domsxe = simplexml_load_string(get_the_post_thumbnail()); $src = $domsxe->attributes()->src; $src_array = wp_get_attachment_image_src(hui_get_attachment_id_from_src($src), 'thumbnail'); $html = sprintf('<li><img src="%s" /></li>', $src_array[0]); } else { $content = $post->post_content; preg_match_all('/<img.*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)?>/sim', $content, $strResult, PREG_PATTERN_ORDER); $images = $strResult[1]; $counter = count($strResult[1]); $i = 0; foreach($images as $src){ $i++; $src2 = wp_get_attachment_image_src(hui_get_attachment_id_from_src($src), 'thumbnail'); $src2 = $src2[0]; if( !$src2 && true ){ $src = $src; }else{ $src = $src2; } $item = sprintf('<li><img src="%s" /></li>', $src); if( $single){ return $item; break; } $html .= $item; if( ($counter >= 4 && $counter < 8 && $i >= 4) || ($counter >= 8 && $i >= 8) || ($counter > 0 && $counter < 4 && $i >= $counter) ){ break; } } } return $html;}function hui_get_attachment_id_from_src ($link) { global $wpdb; $link = preg_replace('/-\d+x\d+(?=\.(jpg|jpeg|png|gif)$)/i', '', $link); return $wpdb->get_var("SELECT ID FROM {$wpdb->posts} WHERE guid='$link'");}

wordpress主题前台调用代码放在需要显示的位置上

<?php echo hui_get_thumbnail(false,true);?>

获取wordpress文章内容中的图片数量值

if( !function_exists('get_post_images_number') ){ function get_post_images_number(){ global $post; $content = $post->post_content; preg_match_all('/<img.*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)?>/sim', $content, $result, PREG_PATTERN_ORDER); return count($result[1]); } } 

wordpress前台显示代码

<?php echo get_post_images_number().'张图片' ?>
