[SOLVED] Passing variables

unai · October 15, 2009

Hi Guys, I am having some in passing variables to another page. I think, maybe the variable is

passing empty, but I can't see why. Below is the code for the pages that variable has to go from

and to. Thanks!

From page

<?php

require_once('../includes/functions.php');

require_once('../includes/session.php');

//require_once('../includes/user.php');

require_once('../includes/pagination.php');

require_once('../includes/lyrics.php');

//1. the current page number ($current_page)

$page = !empty($_GET['page']) ? (int)$_GET['page'] : 1;

//2. records per page ($per_page)

$per_page = 6;

//3. total record count ($total_count)

$total_count = Lyrics::count_all();

// Find all lyrics

//use pagination instead

//$lyrics = Lyrics::find_all();

$pagination = new Pagination($page, $per_page, $total_count);

// Instead of finding all records, just find the records for this page

$sql = "SELECT * FROM lyrics ";

$sql .= "LIMIT {$per_page} ";

$sql .= "OFFSET {$pagination->offset()}";

$lyrics = Lyrics::find_by_sql($sql);

// Need to add ?page=$page to all links we want to

// maintain the current page (or store $page in $session)

?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN""DTD/xhtml1-strict.dtd">

<head>

<title>Capoeira Village - lyrics</title>

</head>

<html>

<body>

<?php include("../public/layouts/header.php"); ?>

<h1 class="welcome">Capoeira Lyrics</h1>

</div>

<ul>

<?php foreach($lyrics as $lyric): ?>

<li><a href="details.php?lyrics_name=<?php echo $lyric->lyrics_name; ?> "><?php echo $lyric->lyrics_name; ?></a></li>

<?php endforeach; ?>

</ul>

</div>

<ul>

<?php

if($pagination->total_pages() > 1) {

if($pagination->has_previous_page()) {

echo "<li><a href=\"index.php?page=";

echo $pagination->previous_page();

echo "\">« Previous</a></li> ";

}

for($i=1; $i <= $pagination->total_pages(); $i++) {

if($i == $page) {

echo " <span class=\"selected\">{$i}</span> ";

} else{

echo " <li><a href=\"index.php?page={$i}\">{$i}</a></li> ";

}

if($pagination->has_next_page()) {

echo "<li><a href=\"index.php?page=";

echo $pagination->next_page();

echo "\">Next »</a></li> ";

}

$page = $_GET['page'];

?>

</ul>

</div>

</body>

</html>

to page

<?php

require_once('../includes/functions.php');

require_once('../includes/session.php');

//require_once('../includes/user.php');

require_once('../includes/pagination.php');

require_once('../includes/lyrics.php');

require_once('../includes/database.php');

//if (!$session->is_logged_in()){ redirect_to("login.php");}

$lyrics = Lyrics::find_by_name($sql = ($_GET['lyrics_name']));

$page = $_GET['page'];

?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN""DTD/xhtml1-strict.dtd">

<head>

<title><?php echo $lyrics->lyrics_name; ?></title>

</head>

<body>

<?php include("../public/layouts/header.php"); ?>

</div>

<?php echo $pages; ?>

</div>

</body>

</html>

Thanks again!!!

I didn't explained my problem before, sorry about that.

I am trying to pass the two variables to another page, um is the name of the song, $song_name,

the other is the page number, the original page is list of song names displayed using pagination,

I could do it when I wasn't using object oriented. I've tried passing it through the Url and with session but no joy. Again thanks!!

sessions are the way to go.....

page1.php

<?php
session_start(); // THIS IS THE MOST IMPORTANT PART

$_SESSION['item_1'] = 'This is the correct';
$_SESSION['item_2'] = 'way to use a session var';


?>

page2.php

<?php
session_start(); // GOT TO START IT AGAIN

echo $_SESSION['item_1'].' '.$_SESSION['item_2'];

?>

Should output

This is the correct way to use a session var

Thank you Chronister, but the problem, a think, is that the variable is not passing to the other page,

maybe the way the variable $page is being used in the code, $page is an attribute of the pagination

class and I am trying to use it twice in the same page, it is confusing me some how. Thanks anyway.

from

<?php echo $pages; ?>

to

<?php echo $page; ?>

Hi Warz I echoed on the page I want to send the variable two, that's way I know the variable is going empty. The same variable is being used on the page for the pagination, check the code and you will see it, and it works, I send it through the Url and it works, thank you anyway!

Hey Warz, I didn't understand at first what you meant, I thought it was to echo the variable to see

if it wasn't empty, it was a situation of overlooking the problem, what a silly mistake. Thanks a lot.
