Pagination in PDO PHP

Question

im trying to learn pagination with PHP/PDO.

            $limit = 20;
            $sth = $conn->prepare(\"SELECT * FROM directory WHERE user_active != \'\'         


        

Answer 1

Please use Below code for Pagination using PDO:

    



getMessage();    }
// No. of adjacent pages shown on each side
$adjacents = 2;
// We will assign variable here for entry By. you can use your variables here.
$EntryBy = "furqan.aziz";
// We Will prepare SQL Query
$STM = $dbh->prepare("SELECT ServerName FROM statstracker WHERE EntryBy = :EntryBy");
// bind paramenters, Named paramenters alaways start with colon(:)
$STM->bindParam(':EntryBy', $EntryBy);
// For Executing prepared statement we will use below function
$STM->execute();
// Count no. of records 
$Records = $STM->rowCount();
// Your File Name will be the same like your php page name which is index.php
$targetpage = "index.php";
// Below is setting for no. of records per page.
$limit = 10; 
$page = $_GET['page'];
if($page) 
//First Item to dipaly on this page
    $start = ($page - 1) * $limit;          
else
//if no page variable is given, set start to 0
    $start = 0;                             
// Get data using PDO prepare Query.
$STM2 = $dbh->prepare("SELECT `SrNo`, `ServerName`, `HiMemUti`, `AvgMemUti`, `HiCpuUti`, `AvgCpuUti`, `HiIOPerSec`, `AvgIOPerSec`, `HiDiskUsage`, `AvgDsikUsage`, `EntryBy` FROM statstracker WHERE EntryBy = :EntryBy ORDER BY SrNo LIMIT $start, $limit");
// bind paramenters, Named paramenters alaways start with colon(:)
$STM2->bindParam(':EntryBy', $EntryBy);
// For Executing prepared statement we will use below function
$STM2->execute();
// We will fetch records like this and use foreach loop to show multiple Results later in bottom of the page.
 $STMrecords = $STM2->fetchAll();
// Setup page variables for display. If no page variable is given, default to 1.
if ($page == 0) $page = 1;
//previous page is page - 1                 
$prev = $page - 1;
//next page is page + 1                     
$next = $page + 1;
//lastpage is = total Records / items per page, rounded up.                         
$lastpage = ceil($Records/$limit);
//last page minus 1 
$lpm1 = $lastpage - 1;                      
//Now we apply our rules and draw the pagination object. We're actually saving the code to a variable in case we want to draw it more than once.
$pagination = "";
if($lastpage > 1)
{   
    $pagination .= "
";
    //previous button
    if ($page > 1) 
        $pagination.= "Previous";
    else
        $pagination.= "Previous"; 

    //pages 
    if ($lastpage < 7 + ($adjacents * 2))   //not enough pages to bother breaking it up
    {   
        for ($counter = 1; $counter <= $lastpage; $counter++)
        {
            if ($counter == $page)
                $pagination.= "$counter";
            else

        }
    }

    {
