Hi gurus!

Recently i am facing a tiny problem. I want to do is pagination like (<< PREVIOUS | INDEX | NEXT >>).

My codes are below.

 

Regards

 

<?php
    $SQL = mysql_query("SELECT id FROM blogmaster ORDER BY id DESC");
    while($ROW = mysql_fetch_array($SQL))
    {
        $MYARRAY[] = $ROW['id'];
    }
    
    $ARRAYCOUNT = count($MYARRAY);
    if($MYARRAY[0] != $_GET['id'])
    {
        $DESC = $MYARRAY[0] + 1;
        
        echo '<a href="/blog/detail.php?id=' .$MYARRAY[$DESC]. '" class="p-link"><< PREV</a>  ';
    }
    echo '<a href="/blog/index.php" class="p-link">INDEX</a>  ';
    if($MYARRAY[$ARRAYCOUNT] != $_GET['id'])
    {
        $ASC = $MYARRAY[$ARRAYCOUNT] - 1;
        
        echo '<a href="/blog/detail.php?id=' .$MYARRAY[$ASC]. '" class="p-link">NEXT >></a>  ';
    }
?>

 

Also how can i paginate something like <<PREV | 1 2 3 4 5 | NEXT>> when user reach page #5 and click NEXT link then page number should change <<PREV | 6 7 8 9 10 | NEXT>>

// Current Page
$page = 1;

// How many records are we showing on a single page?
$records_per_page = 10;

// Calculate the lowest row of data to fetch from the database
$minimum_row = ($page-1) * $records_per_page; // = 0

$query = "SELECT * FROM table LIMIT $minimum_row, $records_per_page";
$result = mysql_query($query) or die("MySQL Error");
if (mysql_num_rows($result) > 0) {
// Deal with your data
}
mysql_free_result($result);

if ($page > 1) {
echo 'Previous Page';
}

// To work out if we should display a next page link we have to find out how many records there are.
$query = "SELECT COUNT(*) AS 'total' FROM table";
$result = mysql_query($query) or die("MySQL Error");
$num_records = mysql_fetch_object($result)->total;

// Work out maximum amount of pages
$max_page = floor($num_records/$records_per_page);

if ($page < $max_page) {
echo 'Next Page';
}

 

I haven't tested the code, and you could probably optimize it a little more.

 

The benefit of running it this way is that you don't fetch every record from the database meaning you use a lot less memory.

Dear micmania 1

Thanks for your afford and code. Unfortunately this is not what i am looking for.

Let's say i have 10 records in my DB and those records are:

 

4

5

9

10

11

19

28

47

48

62

 

And again let's say my visitor arrived index.php at first time. So, visitor will see record #62(because ORDER BY id DESC LIMIT 1).

When visitor click the NEXT >> page i want to get record #48 (as you can see between #48 and #62 is empty).

How can i skip those empty record lines and assign #48 into anchor <a href="index.php?id=48">NEXT >></a>

 

My displaying order is newer to older so NEXT means older record and PREV means newer record.

$id = 10;

$query = "SELECT id, (SELECT id FROM table WHERE id>'$id' ORDER BY id DESC LIMIT 1) AS 'prev',  (SELECT id FROM table WHERE id<'$id' ORDER BY id DESC LIMIT 1) AS 'next' WHERE id='$id' LIMIT 1";

 

EDIT: Changes to subqueries.
