pagination in php recent row first - php

Question

I've created different pages for 20 different rows in my php code, please have a look-
if(isset($_GET['page']))
{
$page = $_GET['page'];
}
else
{
$page = '';
}
if($page=='' || $page==1)
{
$page1=0;
}
else
{
$page1=($page*20)-20;
}
$query="SELECT * FROM issued_books limit $page1,20";
if($did_query_exec=mysqli_query($conn,$query))
{
while($query_exec=mysqli_fetch_array($did_query_exec, MYSQLI_ASSOC))
{
$isret = $query_exec["Date_returned"];
$dateret = $query_exec["Date_returned"];
$dateis = $query_exec['Date_issued'];
//echoing the values here
}
}
$query = "SELECT * FROM `issued_books`";
$Result = mysqli_query($conn, $query);
$cou = mysqli_num_rows($Result);
$a = $cou/20;
echo "</br></br>";
$a = ceil($a);
echo 'Page ';
for($b=$a; $b>=1; $b--)
{
echo "<a href='return-books.php?page=$b' style='text-decoration:none'>$b </a>";
}
The above code creates the link for all the pages with row 1 of page 1 contains the first record inserted by me.
I wish to display the recent most created record in row 1 of page 1
any kinda help would be really appreciated, thanks :)

Answer 1

You have to add ORDER BY with DESC:-
$query="SELECT * FROM `issued_books` ORDER BY id DESC limit $page1,20";
And
$query = "SELECT * FROM `issued_books` ORDER BY id DESC";
Note:- change the column name in ORDER BY according to your wish.
