Guys,

 

How could I keep values when isset() is clicked and after that a link is clicked which does something. I have paging inside if (isset(submit)) and when clicked next on paging everything goes back to previous state it doesn't keep values for filtering.

 

Below is code, I'm using. Please, help...

Form

		<form method="GET" action="<?php echo $_SERVER['PHP_SELF']; ?>">
		<input type="hidden" name="id" value="<?php echo "$id_kalkulacije"; ?>">
		   Upišite podgrupu proizvoda: <input type="text" name="podgrupa_proz">
		   <input type="submit" name="submit1" value="Traži">
		</form>

Php code

else if (isset($_GET["submit1"])) {

//pretraživanje po kategoriji
$id_kalkulacije = $_GET["id"];
$podgrupa_proz = $_GET["podgrupa_proz"];
$_SESSION["podgrupa_proz"] = $podgrupa_proz;

//Početak paginga
		if (isset($_GET['pageno'])) {
   			$pageno = $_GET['pageno'];
		} else {
   			$pageno = 1;
		} // if
		
		$upit11 = mysql_query("SELECT id FROM kalkulacija_stavke WHERE id_kalkulacija = '$id_kalkulacije' AND podgrupa_proizvoda LIKE '%".$_SESSION["podgrupa_proz"]."%'") or die (mysql_error());
		$brojcanik = mysql_num_rows($upit11);
		$rows_per_page = 100;
		$lastpage = ceil($brojcanik/$rows_per_page);
		$pageno = (int)$pageno;

		if ($pageno > $lastpage) {
		   $pageno = $lastpage;
		} // if
		
		if ($pageno < 1) {
		   $pageno = 1;
		} // if
		
		$limit = 'LIMIT ' .($pageno - 1) * $rows_per_page .',' .$rows_per_page;

	if ($pageno == 1) {
   		echo " <font color='#990000'>Početak</font> || Natrag ";
	} else {
   		echo " <a href='{$_SERVER['PHP_SELF']}?pageno=1&id=$id_kalkulacije&podgrupa_proz=$podgrupa_proz'>Prva</a> | ";
	    $prevpage = $pageno-1;
	    echo " <a href='{$_SERVER['PHP_SELF']}?pageno=$prevpage&id=$id_kalkulacije&podgrupa_proz=$podgrupa_proz'>Natrag</a> ";
	} // if
	
		echo " ( <font color='grey'>Stranica - <b>$pageno</b> od <b>$lastpage</b></font> ) ";

	if ($pageno == $lastpage) {
   		echo " Naprijed || <font color='#990000'>Kraj</font> ";
	} else {
	   $nextpage = $pageno+1;
   	   echo " <a href='{$_SERVER['PHP_SELF']}?pageno=$nextpage&id=$id_kalkulacije&podgrupa_proz=$podgrupa_proz'>Naprijed</a> | ";
       echo " <a href='{$_SERVER['PHP_SELF']}?pageno=$lastpage&id=$id_kalkulacije&podgrupa_proz=$podgrupa_proz'>Posljednja</a> ";
	} // if
       echo " <br />Rezultata: ".$brojcanik." </p>";

I did store it in Session, but it doesn't work for some reason which I can't figure out. I do a session_start() in one of the include files I'm using, if you thought I didn't start the session.

 

Is it a problem with if (isset(submit)) that's not set when I click a link for next page on paging part??? If that is the problem how can I go around it?
