Question

Can anyone help in this php page navigation script switch on counting normal serial number? In this script there is a var called \"page_id\" - I want this var to store the real

Answer 1

I were helped by one of the programmers with my above script. So here is a worked example of the reversed page navigation on PHP.

0)$imax=$imax+1;

if($activepage == ''){
$for_start=$imax;
$activepage = $imax-1;
}
$next = $activepage - 1; if ($next<0){$next=0;}
$end =0;
$prev = $activepage + 1; if ($prev>=$imax){$prev=$imax-1;}
$start=  $imax;
if($activepage >= 0){
$for_start = $activepage + $rad + 1;
if($for_start<$rad*2+1)$for_start = $rad*2+1;
if($for_start>=$imax){ $for_start=$imax; }
}

$meter = $rad*2+1;  //$rad; ---------------------
$new_meter = $for_start-1;
if($activepage < $imax-1){
$str .= ' <<< End • < Forward | ';
}
for($i=$for_start-1; $i>-1; $i--){
$meter--;
//$new_meter++;
//$line = '|'; if ($meter=='0'){ $line = ''; }
$line = ''; if ($i>0)$line = '|';
if($i<>$activepage){
$str .= " ".($i)." ".$line." ";
} else {
$str .= " [".($i)."] ".$line." ";
}

if($meter=='0'){ break; }
}
if($activepage > 0){
$str .= " | Back > • Start >>> ";
}

return $str;

}

if(is_numeric($_GET["page"])) $page = $_GET["page"];
$navigation = navigation($onpage, $page); // detect navigation

echo $navigation;
?>

$page = keeps the page number from the reversed order

$page_id = keeps the real page by serial order. so you can make SELECT queries to database and ORDER BY id DESC use.
