PHP MySQL (i) Paging/Paginierung Hilfe

Question

Ich arbeite an Paging/Paginierung Code, aber brauche etwas Hilfe.

Ich habe den Punkt erreicht, wo es alle Seitenzahlen auflistet und angeklickt werden kann. image of paging

Jetzt versuche ich es zu machen, wo es nur 5 Seiten vor und nach der aktuellen Seite ausgibt.

[Erste] [Previous] [6] [7] [8] [9] [10] [] [12] [13] [14] [15] [16] [weiter] [Last]

möchte wirklich etwas Hilfe auf dieser

Vielen Dank im Voraus!

Answer 1

Unter der Annahme, $ Seite ist die aktuelle Seitenzahl, versuchen zu ändern:

for ($upage=1; $upage <= $totalPages; $upage++)

zu

for ($upage=max(1,$page - 5); $upage <= min($totalPages, $page + 5); $upage++)
