En las \u00faltimas publicaciones<\/a>, sabemos que uno de los m\u00e9todos para aumentar las visitas a la p\u00e1gina es mostrar una lista de las publicaciones anteriores. Otro m\u00e9todo es mostrar publicaciones aleatorias. Por supuesto, estamos mostrando las publicaciones usando la miniatura en la publicaci\u00f3n, lo que llamar\u00e1 la atenci\u00f3n. As\u00ed que la mejor idea es ponerlo debajo del men\u00fa de navegaci\u00f3n (algo as\u00ed como el contenido de coincidencia de Google<\/a> ).<\/p>\n

Primero debe definir una funci\u00f3n para recuperar la primera imagen en la publicaci\u00f3n. Esto se debe usar si la [Imagen destacada] no est\u00e1 definida para una publicaci\u00f3n.<\/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 $matches[1][0];\n\u00a0} <\/code><\/pre>\n
Luego coloque lo siguiente en alg\u00fan lugar que desee, por ejemplo, Single.php. Puede ajustar el n\u00famero de publicaciones ($num = 4) en consecuencia.<\/p>\n
