after update go to previous page

[Valkyrian]

Hi,

My products (records) are selected with a number of pages. Then I use
navigationbuttons like first | next | previous | last, to the next or the previous.

like

<a href="<?php printf("%s?pageNum_Recordset1=%d%s", $currentPage, 0, $queryString_Recordset1); ?>">
  <input name="faktura_datum" type="text" id="faktura_datum" value="<? echo $date; ?>" />
  First</a></strong></span></span> | <a href="<?php printf("%s?pageNum_Recordset1=%d%s", $currentPage, max(0, $pageNum_Recordset1 - 1), $queryString_Recordset1); ?>">Previous</a>.....

How Can I go back to the previous page, after updating a record withe the Dream Weaver
"Update Record - Server Behavior" ?

$updateGoTo = "cms.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
    $updateGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $updateGoTo));
}

Now it jumps to the first page after updating and do I have to search to the
page where I was working on. I'm using PHP and MySql

You could use a session variable to keep track of the page number.

session_start();
if(!isset($_SESSION['page'])){
   $lastpage = 1;
}else{
   $lastpage = $_SESSION['page'];
}

//get $max_pages from a mysql_num_rows() - based function?

if(isset($_GET['nav']) && is_int($_GET['nav']) && in_array($_GET['nav'],range(1,$max_pages)){
  $page = $_GET['nav'];
}else{
   $page = (in_array($lastpage,range(1,$max_pages))) ? $lastpage : 1;
}

$_SESSION['page'] = $page;

$link_array = ('first'=>array(1,'« first'),'prev'=>array($page-1,'< previous'),'next'=>array($page+1,'next >'),'last'=>array($max_pages,'last »'));

if($page == 1){
  unset($link_array['first']);
  unset($link_array['prev']);
}elseif($page == $max_pages){
  unset($link_array['prev']);
  unset($link_array['last']);
}

foreach($link_array as $link){
  $link_r[] = "<a href=\"?nav={$link[0]}\">{$link[1]}</a>";
}
$linkstring = "<p>" . implode(" | ", $link_r) . "</p>";

//...

echo $linkstring;

No idea if that works, off top of my head. If you have an update form in this file and you're updating a record in the view, it show return to the same 'page' after form submission.

Thank you ardav but I couldn't get that to work out.

Moore specific, I have one page that lists customers etc. with Dreamweaver recordset pagination to show 50 records at the time.

Master page (adminTest.php)

<?php require_once('xxxxx.php'); ?>

  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {

If I hit next button a couple of times I will get to a page with address like:

adminTest.php?pageNum_Recordset1=1&totalRows_Recordset1=2548

or

adminTest.php?pageNum_Recordset1=4&totalRows_Recordset1=2548

Now if I want to edit a record at lets say

adminTest.php?pageNum_Recordset1=49&totalRows_Recordset1=2548&recordID =248

I click a button to go to the update page.

After update I want to go back to previous page in this case

adminTest.php?pageNum_Recordset1=49&totalRows_Recordset1=2548&recordID =248

But I only comes to the first page in the pagination, of course because I puted that address in

$updateGoTo = "adminTest.php";

Is there a way to fix this, I have played around with session variables but didn't get it to rock

[Karthik_pranas]

You should pass the query_string values to detail.php as

detail.php?pageNum_Recordset1=49&totalRows_Recordset1=2548&recordID =248

and get the values using $_GET in your previous page.

[Valkyrian]

Tank you Karthik_pranas!

Unnfortunately I'm not clever enough to do this, could you be Moore precise please?

Thankyou for your efforts

[Valkyrian]

Ok!

This is what I did:

Master page (adminTest.php)

<?php
session_start(); 
$_SESSION['uri'] = $_SERVER['REQUEST_URI'];
?>

and in
Update Page (detail.php)

$updateGoTo = $_SESSION['uri'];
  if (isset($_SERVER['QUERY_STRING'])) {
    $updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
    $updateGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $updateGoTo));
}

That leads back to previous page in pagination after update, pretty simple I think :)

Any comments, thoughts, complains, bads, goods......?
