Add Pagination To This Php Script

bsnmcahi · October 25, 2012

Hi all! I have this script here I want to add paging to it so that the table only shows 15 rows at a time then offers page numbers below like 1-15, 16-31 etc..

As this is not an SQL database how would I do this??

Any help would be great..

Thanks

Martin

You can paginate an array of data by simply replacing the sql logic with equivalent array functions -

<?php
// pagination from db -> array

$arr = range(1,32); // simulate data

$rows_per_page = 15;

// get total number of rows
/*
$query = "SELECT count(*) FROM table WHERE ...";
$result = mysql_query($query, $db) or trigger_error("SQL", E_USER_ERROR);
list($numrows) = mysql_fetch_row($result);
*/
$numrows = count($arr);

// Calculate number of $lastpage
$lastpage = ceil($numrows/$rows_per_page);

// condition inputs/set default
if (isset($_GET['pageno'])) {
  $pageno = $_GET['pageno'];
} else {
  $pageno = 1;
}

// validate/limit requested $pageno
$pageno = (int)$pageno;
if ($pageno > $lastpage) {
  $pageno = $lastpage;
}
if ($pageno < 1) {
  $pageno = 1;
}

// Find starting array index that corresponds to the requested page no
$start = ($pageno - 1) * $rows_per_page;

// database query
/*
$query = "SELECT * FROM table $limit";
$result = mysql_query($query, $db) or trigger_error("SQL", E_USER_ERROR);
//... process contents of $result ...
*/

$page = array_slice($arr, $start, $rows_per_page, true);
foreach ($page as $key=>$value){
   echo "Key: $key, Value: $value<br />";
}

echo "<br />";

// first/prev pagination hyperlinks
if ($pageno == 1) {
  echo " FIRST PREV ";
} else {
  echo " <a href='?pageno=1'>FIRST</a> ";
  $prevpage = $pageno-1;
  echo " <a href='?pageno=$prevpage'>PREV</a> ";
}

// Display current page or pages
echo " ( Page $pageno of $lastpage ) ";

// next/last pagination hyperlinks
if ($pageno == $lastpage) {
  echo " NEXT LAST ";
} else {
  $nextpage = $pageno+1;
  echo " <a href='?pageno=$nextpage'>NEXT</a> ";
  echo " <a href='?pageno=$lastpage'>LAST</a> ";
}
?>
