Question

I am having some issues trying to create page navigation using php,

I have variable called $PageNo that I can navigate through using using next prev links -1 or +1.

eg.

echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=".($PageNo+1)."'>Next</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=".($PageNo-1)."'>Prev</a>";

but aswell as this is want to display direct links to the pages so i have a navigation like so

PREV 1 2 3 4 NEXT

echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=".($PageNo+1)."'>Next</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=1'>1</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=2'>2</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=3'>3</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=4'>4</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=".($PageNo-1)."'>Prev</a>";

If I know the total number of product pages is 4 how would you generate the links to give

echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=1'>1</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=2'>2</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=3'>3</a>";
echo "<a href='http://".$_SERVER["HTTP_HOST"]."/product.php?page=4'>4</a>";

Any help would be great.

Answer 1

You need to do the math, and then a little bit of code.

1. calculate the number os pages you need (based on the number os records and records per page)

2. Just use a for loop to do links like (not tested):

   for ($page = 1; $page <= $total_pg; ++$page) {
   echo “$page”;
   }

then, the product.php page reads that number and displays the subset of records
