Date control using JavaScript

Date control is a combination of three drop downs with month, day and year valus. It can be used as an alternative to the date picker control. Suppose a user needs to select a date before/after 10 years. At this point selecting the date with a date picker will not be easy and time consuming. So, in this situation, this control may be helpful.

Paging using PHP and MySQL

I have coded a class for paging, you may find it here.

### Code for Paging Starts ###
//index no of the page
$pageIndex = ((int)$_REQUEST['pageIndex'] == 0) ? 1 : (int)$_REQUEST['pageIndex'];
 
//number of rows
$rowPerPage = 10;
 
//counting total number of rows
$sql = 'SELECT COUNT(*)
        FROM {your_table_name}
        WHERE {IF ANY CONDITION}';
 
$query = mysql_query($sql, $link_identifier);
$row = mysql_fetch_row($query);
 
// total records
$totalRecords = $row[0];
 
// number of pages
$totalPages = ceil($totalRecords/$rowPerPage);
 
if($pageIndex > $totalPages)
{
    $pageIndex = $totalPages;
}
 
$startIndex = ($pageIndex - 1) * $rowPerPage;
 
if($totalRecords > $rowPerPage)
{
    $endIndex = $startIndex + $rowPerPage;
}
else
{
    $endIndex = $totalRecords;
}
 
if($pageIndex == $totalPages)
{
    if($totalRecords > $totalPages * $rowPerPage)
    {
        $endIndex = $totalRecords;
    }
}
 
if($totalRecords > 0)
{
    $rangeStart = $startIndex+1;
 
    if(($totalRecords > $rowPerPage) || ($pageIndex == $totalPages))
    {
        $rangeEnd = $totalRecords;
    }
    else
    {
        $rangeEnd = $endIndex;
    }
 
    $range = 'Showing '  . $rangeStart.' - '.$rangeEnd.' of '.$totalRecords;
}
 
// link for next page
$nextLink = 'page_name.php?pageIndex='.($pageIndex + 1);
 
// link for previous page
$previousLink = 'page_name.php?pageIndex='.($pageIndex - 1);
 
// fetching data using pagination
$sql = "SELECT *
            FROM {your_table_name}
            WHERE {IF ANY CONDITION}
            LIMIT $startIndex, $rowPerPage";
 
$query = mysql_query($sql, $link_identifier);
 
### Code for Paging Ends ###

Now use the resource ‘$query’ and do what you want to do.
