dentro de la funcion

Code Select Expand

function theme_linktree($force_show = false)


esta  nuestro  Breadcrumb De SMF, exactamente  en el archivo Index.template.php de nuestro tema.

no te tengo que explicar que es esto o para que sirve, Esta información es redundante y existen muchos artículos en Internet que te explican detalladamente que significa microdata y cual es su función.
pero te dejo el link para que te informes, Esto para que sepas que estamos haciendo
https://developers.google.com/search/docs/data-types/breadcrumbs

Buscaremos  y reemplazaremos esto

Parece interesante algo había leído pero no había tenido tiempo de entenderlo del todo... ya lo mirare y probare en un smf de pruebas tengo!


Saludos!

[^SoporteGSM^]

Basicamente para que sirve este microdata???

[vicram10]

interesante, gracias dhayzon

[jclconsultor]

Buenas tardes Dhayzon, gracias por tu idea, la tome y la efectúe de otra versión como schema, para evitar un efecto que me causa en mi tema bellacita del Forotailandia, anexo como la realice, saludos.

NOTA: A igual que la versión realizada por ti, solo tienes que copiar la función y listo, pruebas con la herramienta de google y indexa, saludos.

Disculpen todos, pero seguí validando ya que en mi tema bellacita se repite 2 veces el esquema y agregue unos cambios con variables globales que impide que se repita el schema en el tema, quedando perfecto:

Nota: por razones de limitacion por politicas de span en el foro, en donde indica la url: schema.org hay que colocar h t t p: / / schema.org, en forma correcta.

Como seria el ajuste en 2.1 RC1???

[Diego Andrés]

Es un poco diferente, pero debería de ser adaptable sin mucho esfuerzo.

Como seria la adaptacion?
