¿Donde esta el fallo en este codigo PHP que a veces no guarda las variables?

Como podreis ver aqui:

http://www.vallromanesverd.es/es/5-mascotas

en la parte central inferior aparecen 3 tabs, "Destacados", "Novedades" y "Mas Vendidos"; el problema esta en que en "Novedades" las imágenes de los productos son correctas, pero en las otras 2 tabs ("Destacados" y "Mas Vendidos") a veces repite las imágenes del producto anterior y no se corresponden.

Os coloco el código PHP separandolo por cada una de esas tabs.

Por cierto y como ultima cosa, este es el código que obtiene la opinión inferior, lo digo para que lo reviséis ya que aunque hay mas de 20 opiniones casi siempre pone la misma.

Ahora solo toca encontrar el "error" y sabes porque repite a veces la imagen de los productos anteriores.

Un saludo y muchas gracias por todo.

PD: Perdón por tanto código.

Hola:

¿Aún tienes el problema o ya lo solucionaste (creo que no lo has arreglado, pero no estoy seguro)?
victor5atodogas · · Solicitar retirada
Si, esta solucionado; este codigo es respecto a mostrar productos en "categorias vacias" en una tienda online; no funcionaba porque esa tienda tenia un "error" y en la SQL hay una consulta que busca la imagen destacada, pero esta tienda no tenia todas las imagenes como destacadas, asi que lo solucione.
