Buenas!<\/p>\n
En el menu de administraci\u00f3n de WordPress tengo creados varios \u00abcustom-posts\u00bb cada uno con sus posts. Ahora en uno de esos post personalizados he creado un campo que recupera todos los posts de los posts personalizados. El problema es que necesitar\u00eda que los ordenara de la siguiente manera:<\/p>\n
Post Personalizado 1:
\nPosts
\nPost Personalizado 2:
\nPosts
\n…<\/p>\n
Os paso el c\u00f3digo que crea el campo y recupera y guarda los datos de select:<\/p>\n
