I am using the following code for pagination with php5 and mysql 4.1.x
The pages advance by clicking on the "Next" or "Last" link
However the url does not advance past this in the url field
http://localhost/page.php?pagenum=2
Also the page count does not increase past
"--Page 1 of 50--" at the bottom of the page regardless of how many
pages forward I have clicked.
If anyone could point me in the right direction to fix this, it would be
much appreciated.
Code:
// Connects to your Database
mysql_connect("dev", localhost", "user", "password") or die(mysql_error());
mysql_select_db("mydatabase") or die(mysql_error());
//This checks to see if there is a page number. If not, it will set it
to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
}
//Here we count the number of results
//Edit $data to be your query
$data = mysql_query("SELECT * FROM main") or die(mysql_error());
$rows = mysql_num_rows($data);
//This is the number of results displayed per page
$page_rows = 8;
//This tells us the page number of our last page
$last = ceil($rows/$page_rows);
//this makes sure the page number isn't below one, or more than our
maximum pages
if ($pagenum < 1)
{
$pagenum = 1;
}
elseif ($pagenum > $last)
{
$pagenum = $last;
}
//This sets range that we will display in our query
$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;
//This is your query again, the same one... the only difference is we
add $max into it
$data_p = mysql_query("SELECT * from main $max") or die(mysql_error());
//This is where you display your query results
while($info = mysql_fetch_array( $data_p ))
{
Print $info['id'];
echo "<br>";
Print $info['bio'];
echo "<br>";
}
echo "<p>";
// This shows the user what page they are on, and the total number of pages
echo " --Page $pagenum of $last-- <p>";
// First we check if we are on page one. If we are then we don't need a
link to the previous page or the first page so we do nothing. If we
aren't then we generate links to the first page, and to the previous page.
if ($pagenum == 1)
{
}
else
{
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=1'> <<-First</a> ";
echo " ";
$previous = $pagenum-1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$previous'> <-Previous</a> ";
}
//just a spacer
echo " ---- ";
//This does the same as above, only checking if we are on the last page,
and then generating the Next and Last links
if ($pagenum == $last)
{
}
else {
$next = $pagenum+1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$next'>Next -></a> ";
echo " ";
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$last'>Last ->></a> ";
}
?>
