How to get selected category id after 1st page in pagination?
- by Surjay
//$id=$_REQUEST['category'];
//$catid=mysql_escape_string($id);
$catid = isset($_GET['category']) ? (int)$_GET['category'] : 0;
$recordsPerPage =4;
0
// //default startup page
$pageNum = 1;
if(isset($_GET['p']))
{
$pageNum = $_GET['p'];
settype($pageNum, 'integer');
}
$offset = ($pageNum - 1) * $recordsPerPage;
//set the number of columns
$columns = 1;
//set the number of columns
$columns = 1;
$query = "SELECT temp_id, temp_img, temp_header, temp_resize, temp_small, temp_name, temp_type, cat_id, col_id, artist_id FROM templates where cat_id = '{$catid}' ORDER BY temp_id DESC LIMIT $offset, $recordsPerPage";
$result = mysql_query($query);
//we add this line because we need to know the number of rows
$num_rows = mysql_num_rows($result);
echo "";
//changed this to a for loop so we can use the number of rows
for($i = 0; $i < $num_rows; $i++) {
while($row = mysql_fetch_array($result)){
if($i % $columns == 0) {
//if there is no remainder, we want to start a new row
echo "";
}
echo ...........my data(s).
if(($i % $columns) == ($columns - 1) || ($i + 1) == $num_rows) {
echo "";
}
}
}
echo "";
//}

<div class="pagination">
<?
$query = "SELECT COUNT( temp_id ) AS `temp_date` FROM `templates` where cat_id ='{$catid}'";

Here my ajax code:
function GetXmlHttpObject(handler)
{
var objXMLHttp=null
if (window.XMLHttpRequest)
{
objXMLHttp=new XMLHttpRequest()
}
else if (window.ActiveXObject)
{
objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP")
}
return objXMLHttp
}
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtResult").innerHTML=xmlHttp.responseText
}
else
{
//alert(xmlHttp.status);
}
}
function htmlData(url, qStr)
{
if (url.length==0)
{
document.getElementById("txtResult").innerHTML="";
return;
}
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request");
return;
}
url=url+"?"+qStr;
url=url+"&sid="+Math.random();
xmlHttp.onreadystatechange=stateChanged;
xmlHttp.open("GET",url,true) ;
xmlHttp.send(null);
}
