Como me gusta compartir cosas que hago , aquí está mi paginación , se puede poner paginación de valores captados de un archivo plano o paginar entradas que se lean de un directorio como fotos , etc , se puede indicar el numero de elementos agrupados como de elementos a mostrar por cada página cambiando los valores , al contrario ..... de lo que "algunos opinan" o dicen mucha gente , aquí se entra para obtener ideas , de como hacer las cosas ..... no para que le hagan ningún trabajo , seamos un poquito ecúanimes .....
Un saludo , espero que les guste y se está abierto a cualquier modificación y ayuda que mejore el script , un saludo nuevamente |
