Limit Pagination pages in PhP

Question

I have a hash database on my own site, and I wanted to paginate (because 210.000hashes won't load easily without slowing down the site)

now I have paginated my stuff, but I get about 21.000 pages how can I limit this to about 100pages???

$sql = "SELECT * FROM hashes";
$rs_result = mysql_query($sql); //run the query
$total_records = mysql_num_rows($rs_result);  //count number of records
$total_pages = ceil($total_records / $num_rec_per_page); 

echo "<a href='?page=1'>".'|<'."</a> "; // Goto 1st page  

for ($i=1; $i<=$total_pages; $i++) { 
        echo "<a href='?page=".$i."'>".$i."</a> "; 
}; 
echo "<a href='?page=$total_pages'>".'>|'."</a> "; // Goto last page

Please don't mind the crappy way I made it, I just want it to work, not look pretty :)

Answer 1

Pagination in php

Limit the number of items per page by

if(isset($_GET['page']))
    $page=$_GET['page'];
else 
    $page=1;

$max_results=6;
$from=( ($page * $max_results) - $max_results);     

in this i limit 6( $max_results=6; ) items per page you can change according to your need

Use the query to limit the results

$search=mysql_query("SELECT * FROM `hashes` LIMIT $from,$max_results"); 
$total_results=mysql_result(mysql_query("select count(*) as num from `hashes`"),0);
while($r=mysql_fetch_object($search))
{//your code}

Pagination concept to provide links for pages

$total_pages=ceil($total_results/$max_results);
if($total_results>$max_results)
{
if($page>1)
{
    $prev=($page-1);
    echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$prev\" style='text-decoration:none'>&nbsp;<< Previous&nbsp;</a>";
}
for($i=1;$i<=$total_pages;$i++)
{
    if($page==$i)
    {
        echo $i."";
    }
    else
    {
        echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$i\" style='text-decoration:none'>&nbsp;$i&nbsp;</a>";
    }
}
if($page<$total_pages)
{
    $next=($page+1);
    echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$next\" style='text-decoration:none'>&nbsp;Next>></a>";
}
}

考虑在sql查询中使用LIMIT子句-这将是有效的并且可以解决您的问题

Answer 3

This piece of code made it work for me :) (the '5' pieces still gotta be editted with the $max_pages

$max_pages = 10;
$rs_result = mysql_query($sql); //run the query
$total_records = mysql_num_rows($rs_result);  //count number of records
$total_pages = ceil($total_records / $num_rec_per_page); 

echo "<a href='?page=1'>".'|<'."</a> "; // Goto 1st page  

for ($i = max(1, $page - 5); $i <= min($page + 5, $total_pages); $i++) { 
            echo "<a href='?page=".$i."'>".$i."</a> "; 
}; 
echo "<a href='?page=$total_pages'>".'>|'."</a> "; // Goto last page
