I am trying to implement a simple php pagenation script however it only seems to work on the first result only. Please see the code below:
can anyone help with this???
I know the issue is that $pagenum isn’t being updated with each pass however I have no clue as to where to update it.
//connects to database
mysql_connect("localhost","root","") or die('Could not connect to mysql server' . mysql_error());
mysql_select_db("joomla") or die ('Could not connect to database' . mysql_error());
//This checks to see if there is a page number. If not, it will set it to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
echo $pagenum;
}
//Here we count the number of results
$data = mysql_query("SELECT * FROM jos_content") or die ('Could not query database' . mysql_error());
$rows = mysql_num_rows($data);
//This is the number of results displayed per page
$page_rows = 6;
//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 the range to 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 jos_content $max") or die(mysql_error());
//This is where you display your query results
while($info = mysql_fetch_array($data_p))
{
echo "<a href='article_desc.php?id=".$info['id']."'>".$info['title']."</a>";
echo "<hr />";
}
// 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> ";
}
