I have a database field with large text. If there is a tag inside <!-- new page --> I want to paginate by that tag.
What I'm trying to do is something like WordPress has, when you insert a tag such as <!-- new page --> I want to create a new page.
Say I have this text from a database
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque elementum magna in nulla ultrices, eu pulvinar nulla auctor. Praesent auctor ut dui vitae feugiat.
<!-- new page -->
Sed risus nisl, tristique sed tristique et, auctor eu augue. In hac habitasse platea dictumst. Fusce a ipsum ligula. Aliquam vestibulum ligula ut ligula porta gravida. Curabitur tincidunt a est vitae eleifend. Duis ullamcorper nunc sapien, quis molestie tellus ornare vel. Nullam in mi eros.
How would I make the second paragraph appear on a new page?
Something like this http://en.support.wordpress.com/splitting-content/nextpage/

i hope my code will be helpfull :
<?php
//in this example :
//first you have to create a database with name : blog
// create table : article (id as primary key, name , content)
// here we supposed that in the content you have your tags <!-- new page -->
// also i supposed the name of this file as : pagination.php
//Getting the id of article:
//=========================
if(isset($_GET['id']))
$id_article = $_GET['id'];
else
$id_article = 1;
//Connexion to database :
//======================
$user="root";
$pass="root";
$db="blog";
$host="localhost";
$pdo_options[PDO::ATTR_ERRMODE] = PDO::ERRMODE_EXCEPTION;
$bdd = new PDO('mysql:host='.$host.';dbname='.$db, $user, $pass, $pdo_options);
$bdd->query("SET NAMES 'utf8'");
$response = $bdd->query('SELECT * FROM articles WHERE id='.$id_article);
$tab_content = array();
$data = $response->fetch()
echo'<div >';
$tab_content = explode('<!-- new page -->',$data['content']);
$count_pages = count($tab_content);
if($count_pages){
//in the case that you have somme tags :
//=====================================
echo $tab_content[$page];
echo '<br>';
for($i=1;$i<$count_pages;$i++)
echo ''.$i.' ';
}
else{
//if no tags '<!-- new page -->' in your content:
//===============================================
echo $data['content'];
}
echo '</div>';
$response->closeCursor();
?>
