[SOLVED] Pagination and Jump Menu

issso · October 5, 2007

Hi everyone,

I have been working on a pagination script for an online product catalog site I'm building.

I'm having a problem with next and prev links, they're not working as they should

I'm not getting the next set of results nor the previous, I keep getting the same page.

Truly appreciate any help.

Thanks

Here's the test page:

http://iz.myftp.org/eb/HTML/products3.php?cat=2&ppp=5

And the code is below:

<script type="text/JavaScript">

function MM_jumpMenu(targ,selObj,restore){ //v3.0
  eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
  if (restore) selObj.selectedIndex=0;
}

</script>

<link href="eb.css" rel="stylesheet" type="text/css" />

</head>

<body>

<?

$catid			= $_GET["cat"];            
$max_results	= $_GET["ppp"]; 

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


$from = (($page * $max_results) - $max_results); 


$sql = mysql_query("SELECT * FROM items LIMIT $from, $max_results");

$total_results = mysql_result(mysql_query("SELECT COUNT(*) as Num FROM items WHERE cat_id = '$catid'"),0);

double check that $page is being updated to the next page. echo it after you set it... so put it in like this:

if(!isset($_GET['page'])){
	$page = 1;
} else {
	$page = $_GET['page'];
}
echo $page;

put a few more echo statements in just to try and narrow down the problem.

Change $query3 to the follwoing

$query3="SELECT * FROM items where cat_id = '$catid' LIMIT $from, $max_results";

JasonLewis · October 6, 2007

on wat madtechie said, why do you have this query...

$sql = mysql_query("SELECT * FROM items LIMIT $from, $max_results");

when it isnt even used any where else?

looks like you wrote that query then wrote $query3 later on which does the same except selects only for a certain category.

Thanks a lot guys, that did it!

ProjectFear, I put the echo statement, and it's returning the correct page.

But you were right about the $sql query, it wasn't used anywhere, and I was relying on it to give me the results

limited by $from, $max_results

MadTechie, thanks for your revised query, it works now and I deleted the $sql query.

Here's the updated page:

http://iz.myftp.org/eb/HTML/products3.php?cat=2&ppp=5

I knew there was mix up in my code, because I wrote each part of this seperatly, I did the jump menu first then I Was trying the pagination.

Thanks a lot guys you were a great help.

Regards
