How do I add a filter button to this pagination?
- by ClarkSKent
Hey, I want to add a button(link), that when clicked will filter the pagination results.
I'm new to php (and programming in general) and would like to add a button like 'Automotive' and when clicked it updates the 2 mysql queries in my pagination script, seen here:
As you can see, the category automotive is hardcoded in, I want it to be dynamic, so when a link is clicked it places whatever the id or class is in the category part of the query.
1:
$record_count = mysql_num_rows(mysql_query("SELECT * FROM explore WHERE category='automotive'"));
2:
$get = mysql_query("SELECT * FROM explore WHERE category='automotive' LIMIT $start, $per_page");
This is the entire current php pagination script that I am using:
<?php
//connecting to the database
$error = "Could not connect to the database";
mysql_connect('localhost','root','root') or die($error);
mysql_select_db('ajax_demo') or die($error);
//max displayed per page
$per_page = 2;
//get start variable
$start = $_GET['start'];
//count records
$record_count = mysql_num_rows(mysql_query("SELECT * FROM explore WHERE category='automotive'"));
//count max pages
$max_pages = $record_count / $per_page; //may come out as decimal
if (!$start)
$start = 0;
//display data
$get = mysql_query("SELECT * FROM explore WHERE category='automotive' LIMIT $start, $per_page");
while ($row = mysql_fetch_assoc($get))
{
// get data
$name = $row['id'];
$age = $row['site_name'];
echo $name." (".$age.")<br />";
}
//setup prev and next variables
$prev = $start - $per_page;
$next = $start + $per_page;
//show prev button
if (!($start<=0))
echo "<a href='pagi_test.php?start=$prev'>Prev</a> ";
//show page numbers
//set variable for first page
$i=1;
for ($x=0;$x<$record_count;$x=$x+$per_page)
{
if ($start!=$x)
echo " <a href='pagi_test.php?start=$x'>$i</a> ";
else
echo " <a href='pagi_test.php?start=$x'><b>$i</b></a> ";
$i++;
}
//show next button
if (!($start>=$record_count-$per_page))
echo " <a href='pagi_test.php?start=$next'>Next</a>";
?>
