崇高片段：pageit

Posted 2021-02-23

This is a quick sublime snippet to quickly setup a DB table for pagination. Ideally from here you will be into a smarty template.

<snippet>
  <content><![CDATA[
 
$offset = 0;
$page = 1;
$pp = 6;
$table = "users";
$field = "user_created_timestamp";
$dir = "DESC";
 
if( isset( $_GET['p'] ) ) {
  $page = intval( $_GET['p'] );
  $offset = ( $page - 1 ) * $pp;
}
 
// get the total
$q = "SELECT COUNT( * ) AS total FROM $table";
$qr = dbQuery( $q );
$qrow = dbFetchArray( $qr );
$total = $qrow['total'];
 
 
// Do the real select
$q = "SELECT * FROM ".$table." ORDER BY ".$field." ".$dir." LIMIT ".$pp." OFFSET ".$offset;
$qr = dbQuery( $q );
 
$assigns['total'] = $total;
$totalpages = ceil( $total / $pp );
$assigns['totalpages'] = $totalpages;
$assigns['items'] = dbFetchAllArray( $qr );
 
$prev = false;
$first = false;
$next = true;
$last = true;
 
if( $offset != 0 ) {
  $prev = true;
  $first = true;
}
 
if( $page == $totalpages ) {
  $next = false;
  $last = false;
}
 
$assigns['prevpage'] = $page - 1;
$assigns['nextpage'] = $page + 1;
$assigns['first'] = $first;
$assigns['prev'] = $prev;
$assigns['next'] = $next;
$assigns['last'] = $last;
