PHP & MySQL Pagination

I have a MySQL query

SELECT * FROM 'redirect'
WHERE 'user_id'= \''.$_SESSION['user_id'].开发者_C百科' \' 
ORDER BY 'timestamp'`

I want to paginate 10 results per page. How Can I do it?


Here is a nice starting point:

<?php

// insert your mysql connection code here

$perPage = 10;
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$startAt = $perPage * ($page - 1);

$query = "SELECT COUNT(*) as total FROM redirect
WHERE user_id = '".$_SESSION['user_id']."'";
$r = mysql_fetch_assoc(mysql_query($query));

$totalPages = ceil($r['total'] / $perPage);

$links = "";
for ($i = 1; $i <= $totalPages; $i++) {
  $links .= ($i != $page ) 
            ? "<a href='index.php?page=$i'>Page $i</a> "
            : "$page ";
}


$r = mysql_query($query);

$query = "SELECT * FROM 'redirect'
WHERE 'user_id'= \''.$_SESSION['user_id'].' \' 
ORDER BY 'timestamp' LIMIT $startAt, $perPage";

$r = mysql_query($query);

// display results here the way you want

echo $links; // show links to other pages


Use LIMIT.

SELECT *
FROM redirect
WHERE user_id = '35251' 
ORDER BY timestamp
LIMIT 40, 10

40 is how many records to skip, 10 is how many to display.

There are also a few problems with your PHP. You use backticks (not single quotes) to surround table and column names. And you shouldn't use string concatenation to build your query.


Here is my code
which contains next and Previous button

<?php  
    $limit = 3;  //set  Number of entries to show in a page.
    // Look for a GET variable page if not found default is 1.        
    if (isset($_GET["page"])) {    
    $page  = $_GET["page"];    
    }    
    else { $page=1;    
    } 
    //determine the sql LIMIT starting number for the results on the displaying page  
    $page_index = ($page-1) * $limit;      // 0

    $All_Users=mysqli_query($con,"select * from users limit $page_index, $limit");
    while($row=mysqli_fetch_array($All_Users))
    {
        //show  data in table or where you want..
    }
    $all_data=mysqli_query($con,"select count(*) from users");
    $user_count = mysqli_fetch_row($all_data);   // say total count 9  
    $total_records = $user_count[0];   //9
    $total_pages = ceil($total_records / $limit);    // 9/3=  3
    if($page >= 2){
        echo "<a href='blog.php?page=".($page-1)."' class='btn 
     customBtn2'>Previous</a>";
      }
    
    if($page<$total_pages) {
        echo "<a href='blog.php?page=".($page+1)."' class='btn customBtn2'>NEXT</a>";   
    }       
?>


Use the LIMIT clausule of the query to limit the amount of results you retrieve from the database.
