I want to break a table of data into Pages so that I don't have to scroll down too much when searching for a record.
Up to now my research has found me some ways of doing this but all of them include about 100+ lines of coding/script.
Now I want to say that I am NOT LAZY, but I do wonder whether this is really neccessary or if there is a shorter and simpler way.
Assuming that I can write a Where clause + IF statement and what else not might be included in getting or posting data with less than 100 lines of script, I can't help to think that it cannot be right having to have such a long script just to add pages to a table of data..
Anyone know a/some good links or easy scripts? Or is this rly something that requires that much script?
Cheers!
Found a solution ..

I am having an issue with a pagination script that I found on the internet but can no longer find the exact one.
The issue is that clicking the previous/next or any page number on the menu does not show the next set of values, presumably the LIMIT OFFSET in my SELECT statement isn't doing as it should, but I am unsure as to why. jobs.php?action=listActiveJob&page=1&ipp (ipp being in thr paginator lcass below as 5), this show the first 5 as expected, when clicking next or page 2 for example the URL changes to jobs.php?action=listActiveJob&page=2&ipp=5 but the same 5 results are shown.
jobs.php contains a lot of code that control several pages, but here is the code that controls this list
function listActiveJob() {
$results = array();
$data = Job::getActiveList();
$results['activejobs'] = $data['results'];
$results['totalRows'] = $data['totalRows'];
require( TEMPLATE_PATH . "/job/listActiveJob.php" );
}
In anouther file(Job.php), here is the code for $data = Job::getActiveList();
public static function getActiveList() {
$conn = new PDO( DB_DSN, DB_USERNAME, DB_PASSWORD );
$pages = new Paginator;
$pages->items_total = 50;
$pages->paginate();
$sql = "SELECT SQL_CALC_FOUND_ROWS job_code, job_id, job_status, job_quoteid, job_contactid, job_companyid, job_schedulestatus, job_schedulestatus2, job_schedulestatus3
FROM jobs WHERE job_status='Active'
ORDER BY job_id DESC ".$pages->limit;
$st = $conn->prepare( $sql );
$st->execute();
$list = array();
while ( $row = $st->fetch() ) {
$job = new Job( $row );
$list[] = $job;
}
$sql = "SELECT FOUND_ROWS() AS totalRows";
$totalRows = $conn->query( $sql )->fetch();
$conn = null;
return ( array ( "results" => $list, "totalRows" => $totalRows[0] ) );
}
the list is then in listActiveJob.php and is a simple foreach
<?php foreach ( $results['activejobs'] as $job ) {
//BLA BLA LIST
}?>
here is the code at the bottom of listActiveJob.php to show and control the pagination.
<?php
$pages = new Paginator;
$pages->items_total = $results['totalRows'];
$pages->paginate();
?>
<p><?php echo $pages->display_pages();?></p>
<p><?php echo '<span class="paginationbox" style="\"margin-left:25px;\""> '. $pages->display_jump_menu() . '</span>'; ?></p>

I hope I have explained this well enough and greatly appreciate any help getting me in the right direction
I'm assuming that .$pages->limit in your sql statement in public static function getActiveList() adds the MySQL Limit statement to your query. However, I don't see where and how it's created in your code above. Since you're always returning the same data set, you might want to have a look there.
In my database query, it returns set of image names. I want to display them in a small size window (say 3x3), if there are more images (>9) it will populate to the next window by a tab or a specific symbol. People can click to that symbol to open the next window. I also want to recognize which image is chosen by user.
The idea of display is something like emoticon window in this image.
Do you have any idea I can make it in php ?
Here is what I am trying, please feel free to correct my code:
<?php include "dbConnector.php" ; ?>
<table>
<tr>
<?php
require_once ("paginator.php");
$pages = new Paginator; //ew paginator object to play with and initializes the default values behind the scenes
$connector= new DbConnector();
$queryObj = mysql_query("SELECT COUNT(*) FROM `mydb`.`images`");
$num_rows = mysql_num_rows($queryObj);
$pages->items_total = $num_rows; //assigns total number of records to our paginator's items_total property
$pages->mid_range = 7;//number of page links to display.
$pages->paginate();//ell the paginator to get to work and paginate
$x = mysql_query( "SELECT * FROM `mydb`.`images` ORDER BY `name` DESC $pages->limit");
$i = 0;
while($row = mysql_fetch_assoc($x))
{
$i++;
echo "<td><img src='imagefolder/".$row['name'].".png'/></td>";
if ($i % 3 == 0) {
echo '</tr><tr>';}
}
echo "Page $pages->current_page of $pages->num_pages";
echo $pages->display_pages();//displays our page numbers
?>
</tr>
<table>
The dbConnector.php as requested:
<?php
define("EW_CONN_PORT", 3306, TRUE);
define("EW_CONN_HOST", "localhost", TRUE);
define("EW_CONN_DB", "server", TRUE);
define("EW_CONN_USER", "root", TRUE);
define("EW_CONN_PASS", "admin", TRUE);
class DbConnector {
// Database connection
var $theQuery;
var $link;
function DbConnector(){
// Get the main settings from the array we just loaded
$host = 'localhost';
$db = 'mydb';
$user = 'root';
$pass = '';
// Connect to the database
$this->link = mysql_connect($host, $user, $pass);
mysql_select_db($db);
register_shutdown_function(array(&$this, 'close'));
}
//*** Function: query, Purpose: Execute a database query ***
function query($query) {
$this->theQuery = $query;
return mysql_query($query, $this->link);
}
//*** Function: fetchArray, Purpose: Get array of query results ***
function fetchArray($result) {
return mysql_fetch_array($result);
}
//*** Function: close, Purpose: Close the connection ***

$pages = new Paginator;
$pages->items_total = $num_rows[0];

$pages->paginate();

I hope someone can help! Tnx in advance
I have a php website which has to display list of items on a page in paginated format.I achieved this using php but now I want to add ajax functionality to it.So I added this function to be called on the click of the page no in the paginated portion.
Ajax/Jquery function:(.paginate is the class for the page links)
$(document).ready(function()
{
$('.paginate').live('click', function(e)
{
//alert("Here");
e.preventDefault();
var btnPage = $(this);
//alert(btnPage.attr('href')); /RealEstate/process.php?page=3&ipp=2&venue=Array $('#temp').load($(this).attr("href")+' #temp');
var getUrl = btnPage.attr('href');
//var dataLocality = { 'locality[]' : []};
//alert(getUrl);
$.ajax(
{
url:btnPage.attr('href'),
success : function(resp)
{
// replace current results with new results.
$('#project_section').html(resp);
},
error : function()
{
window.location.href = btnPage.attr('href');
}
});
});
});
My paginate function is somewhat like this:
function paginate()
{
if(!isset($this->default_ipp)) $this->default_ipp='2';
if($_GET['ipp'] == 'All')
{
$this->num_pages = 1;
}
else
{
if(!is_numeric($this->items_per_page) OR $this->items_per_page <= 0) $this->items_per_page = $this->default_ipp;
$this->num_pages = ceil($this->items_total/$this->items_per_page);
}
$this->current_page = (isset($_GET['page'])) ? (int) $_GET['page'] : 1 ; // must be numeric > 0
$prev_page = $this->current_page-1;
$next_page = $this->current_page+1;
if($_GET)
{

$this->limit = ($_GET['ipp'] == 'All') ? "":" LIMIT $this->low,$this->items_per_page";
}
On the page where I want to display the paginated div,i am getting the entire page as response instead of the paginated div.I have separated the paginated div to a separate page and included it(added code below) on the display page,but not working.
<div id="project_section">
<?php include_once("cityPropertySearchResults.php");?>
</div>
Can someone throw some light over it?
UPDATED:
I found something similar here
This works for the links but now,all the js files go on loading again and again,recursively.
Thanks for your time.
First assign the limit start as 0 after the first page load increase the limit start values as the limit per page and pass that value through the ajax and in the query use that limit start (e.g SELECT * FROM tbl LIMIT 0,10;)
I am working on a PHP-Mysql based website which has some large lists to display(for example product lists).Now I had to break it down to pages for the convenience of the user.So I have added pagination using PHP.Now this does a page refresh each time I click on the page number.So I have a base with PHP/MySQL and want to add Ajax/jquery to it for avoiding unnecessary page refresh.How can I add pagination to the existing code that I have??
Here is the php code for reference.
<div class="flt width710">
<div style="margin-top:10px;" class="flt mapnewalert"> <?php //echo ucfirst($_SESSION['$city']) ?></div>
<div style="float:right" id="toppagesel">
<?php
echo $pages->display_pages();
echo $pages->display_items_per_page();
//echo "<span class=\"\">".$pages->display_jump_menu()."</span>";
$query = "SELECT * from properties,locality,cities where properties.city_id='".$_SESSION['$cityId']."' and properties.locality_id=locality.locality_id and properties.city_id=cities.city_id $pages->limit";
$result = mysql_query($query) or die(mysql_error());
//$getProperty = $propertyDetails->getPropertyDetailsByCityIdPaginate($_SESSION['$cityId'],$limit);
?>
<?php //echo $pages->display_pages(); ?><?php //echo $pages->display_items_per_page();?>
</div>
</div>
And the pagination class:

var $items_per_page;

How can I achieve it??I referred other threads and tried but couldn't get it working in my context.I am a newbie to ajax jquery part so sorry if its a easy task!! :P
PS: Is this possible in the current scenario or do I have to make the changes to my pagination class and php code.Please throw some light on it!!
Thanks
There are many JavaScript pagination library will help you to simplify your work,
can you try this pagination library,

success : function(resp)
{
// replace current results with new results.
$('#project_section').html(resp);
},
error : function()
{
window.location.href = btnPage.attr('href');
}
});
});
});

I got the answer here
Thanks
