Negli ultimi post<\/a>, sappiamo che uno dei metodi per aumentare le visualizzazioni di pagina \u00e8 mostrare un elenco di post in passato. Un altro metodo \u00e8 mostrare post casuali. Ovviamente, stiamo mostrando i post usando la miniatura nel post, che attirer\u00e0 l’attenzione. Quindi l’idea migliore \u00e8 metterlo sotto il menu di navigazione (qualcosa come il contenuto della corrispondenza di Google<\/a> ).<\/p>\n

Dovresti prima definire una funzione per recuperare la prima immagine nel post. Da utilizzare se l'[immagine caratteristica] non \u00e8 definita per un post.<\/p>\n

\u00a0function catch_first_image($post_id) {\n\u00a0 \u00a0ob_start();\n\u00a0 \u00a0ob_end_clean();\n\u00a0 \u00a0$related_post = get_post($post_id);\n\u00a0 \u00a0$content = $related_post->post_content;\n\u00a0 \u00a0$output = preg_match_all('\/<img.+src=['\"]([^'\"]+)['\"].*>\/i', $content, $matches);\n\u00a0 \u00a0return $matches[1][0];\n\u00a0} <\/code><\/pre>\n
Quindi inserisci quanto segue da qualche parte, ad esempio Single.php. Puoi regolare il numero di post ($num = 4) di conseguenza.<\/p>\n
<style>\n.justyyimg {max-width:120px; height: 120px;}\n<\/style>\n\u00a0\n<div id=\"related-posts\">\n\u00a0 \u00a0 <div class=\"related\" class=\"clearfix\">\n\u00a0 \u00a0 \u00a0 <?php \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\n\u00a0 \u00a0 \u00a0 $post_num = 4;\n\u00a0 \u00a0 \u00a0 $exclude_id = $post->id; \n\u00a0 \u00a0 \u00a0 $args = array(\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 'post_status' => 'publish',\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 'post__not_in' => explode(',', $exclude_id),\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 'orderby' => 'rand',\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 'posts_per_page' => $post_num\n\u00a0 \u00a0 \u00a0 );\n\u00a0 \u00a0 \u00a0 query_posts($args);\n\u00a0 \u00a0 \u00a0 while( have_posts()) { the_post(); ?>\n\u00a0 \u00a0 \u00a0 <a href=\"<?php echo the_permalink(); ?>\" title=\"<?php the_title(); ?>\" >\n\u00a0 \u00a0 \u00a0 <?php \n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 if (has_post_thumbnail()) {\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 the_post_thumbnail();\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 } else {\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 $img = catch_first_image(get_the_id());\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 if (strlen($img)) {\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 echo \"<img alt='\".get_the_title().\"' class='justyyimg' src=\"\".$img.\"\"\/>\";\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 } else {\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 echo \"<img alt='\".get_the_title().\"' class='justyyimg' src=\"<a class=\"vglnk\" target=\"_blank\" href=\"https:\/\/justyy.com\/jpg\/\".mt_rand\" rel=\"nofollow\"><span>https<\/span><span>:\/\/<\/span><span>justyy<\/span><span>.<\/span><span>com<\/span><span>\/<\/span><span>jpg<\/span><span>\/\".<\/span><span>mt<\/span><span>_<\/span><span>rand<\/span><\/a>(1, 20).\".jpg\"\/>\";\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 }\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 }\n\u00a0 \u00a0 \u00a0 ?><\/a>\n\u00a0 \u00a0 \u00a0 <?php\n\u00a0 \u00a0 \u00a0 \u00a0 $exclude_id .= ','. get_the_id(); \u00a0 \u00a0 \u00a0 \u00a0 \n\u00a0 \u00a0 \u00a0 } \n\u00a0 \u00a0 \u00a0 wp_reset_query();\n\u00a0 \u00a0 \u00a0 ?>\n\u00a0 \u00a0 <\/div>\n<\/div> \u00a0 \u00a0 \u00a0 \u00a0 \u00a0<\/code><\/pre>\n
Usiamo has_post_thumbnail()<\/strong> per verificare prima l’esistenza delle miniature dei post.<\/p>\n
