En esta unidad vamos a ver una serie de buenas pr\u00e1cticas con c\u00f3digo PHP<\/strong> de la mejor forma para que podamos dejar de mezclar c\u00f3digo PHP<\/strong> con c\u00f3digo HTML.<\/strong><\/p>\n\n\n\n\n\n\n\n

The Loop<\/h2>\n\n\n\n

Hoy vamos a ver un concepto que se denomina the_loop,<\/em> que es el proceso que nos va a permitir traer las publicaciones, las entradas a nuestro WP.<\/strong><\/p>\n\n\n\n

L\u00f3gica de nuestro loop<\/h3>\n\n\n\n

Los pasos que vamos a tener que hacer son:<\/p>\n\n\n\n

    \n
  • Si hay entradas\n
      \n
    • Mientras hay entradas<\/li>\n\n\n\n
    • Muestra la info de las entradas<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Si no hay entradas\n
        \n
      • No hay entradas publicadas<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

        Nos permite invocar el t\u00edtulo,<\/strong> la hora.<\/strong><\/p>\n\n\n\n

        M\u00e9todo the_post()<\/h3>\n\n\n\n

        Nos permite ver la informaci\u00f3n de las entradas (t\u00edtulo, contenido, im\u00e1gen destacada, categor\u00eda, tags\u2026).<\/strong> Mostrar\u00e1 el n\u00famero de entradas que tengamos configuradas en nuestro WP.<\/p>\n\n\n\n

        Acceder a las propiedades<\/h3>\n\n\n\n

        Lo que hacemos es invocar cada uno de los distintos contenidos que tenemos mediante diferentes funciones que existen.<\/p>\n\n\n\n

          \n
        • the_title()<\/em><\/strong>: imprime el t\u00edtulo. Nos muestra las \u00faltimas 5 publicaciones.<\/li>\n\n\n\n
        • the_permalink()<\/em><\/strong>: nos da la URL amigable de como nosotros configuramos los enlaces permanentes para cada una de estas publicaciones.<\/li>\n\n\n\n
        • the_date(<\/em><\/strong>): muestra la fecha, depende de como la hayamos configurado en nuestro WP.<\/strong> NO USAR<\/li>\n\n\n\n
        • the_time()<\/em><\/strong>: muestra la hora o fecha (the_time(\u2018d-M-Y\u2019);). Utilizar esta<\/li>\n\n\n\n
        • the_excerpt()<\/em><\/strong>: nos muestra un estracto de nuestras publicaciones.<\/li>\n\n\n\n
        • the_category()<\/em><\/strong>: muestra las categor\u00edas. Imprime una lista de categor\u00edas<\/li>\n\n\n\n
        • the_tags()<\/em><\/strong>: muestra las etiquetas. Muestra una lista separada por comas con todas las etiquetas.<\/li>\n\n\n\n
        • the_author()<\/em><\/strong>: muestra el autor.<\/li>\n\n\n\n
        • the_content()<\/em><\/strong>: trae todo el contenido de la publicaci\u00f3n.<\/li>\n<\/ul>\n\n\n\n

          Cuando terminemos el proceso del while<\/h2>\n\n\n\n

          Es importante resetear todo el proceso del loop mediante la siguiente funci\u00f3n:<\/p>\n\n\n\n

            \n
          • rewind_posts();<\/em><\/strong><\/li>\n<\/ul>\n\n\n\n

            Que limpia el cach\u00e9. Mejora la carga de nuestras publicaciones. Se coloca debajo del endif.<\/em><\/strong><\/p>\n\n\n\n

            Con las poquitas funciones que tenemos que saber de WP,<\/strong> podemos si somos Frontends personalizar lo que queramos de nuestro WP.<\/strong><\/p>\n\n\n\n

            B\u00fasquedas personalizadas<\/h2>\n\n\n\n

            Para b\u00fasquedas personalizadas usamos una funci\u00f3n que tiene que ir antes del loop<\/strong> de entradas.<\/p>\n\n\n\n

              \n
            • query_posts();<\/em><\/strong><\/li>\n<\/ul>\n\n\n\n

              Ejm<\/strong><\/p>\n\n\n\n

              query_posts( 'order=ASC&category_name=gigantes&por_per_page=3');<\/pre>\n\n\n\n
              Mostrar\u00e1 de m\u00e1s antiguo a m\u00e1s moderno y categor\u00eda gigantes y de 3 en 3. Dar una visita a query_post()<\/em><\/strong> para ver las opciones que tenemos que se pueden pasar como par\u00e1metros.<\/p>\n","protected":false},"excerpt":{"rendered":"
