In this tutorials we will create Jquery Ajax price range slider with PHP,Mysql .This is very useful for user that allow to filter data/items based on rang slider drag rather than typing price .
Nowadays , this is quite common requirements for websites that have products to display or sell .
Generally the website can be accessed by typing http://server_ip/~cpanelusername/ on the server’s cpanel without Domain name Server ( DNS ) pointing . But in some hosting provider disable this feature due to security reasons . Thus ‘mod_userdir’ is disabled and you can’t enable it on your shared hosting . However , we have an alternate method to test our new server . Follow below tutorials : http://unitedwebsoft.in/blog/access-website-without-domain-name-assigned/
Any web application may need send email through it’s script. In PHP, we use mail() function to send from web server .However sometimes it may cause delivery issue.
Means when we send email from php using just mail() function , sometimes recipient don’t receive the mail .To overcome this issue we need SMTP to send email in php .

Photo Galley is a most used section in any website . We can use photo gallery to display portfolio images , event’s photos, client’s logo etc . Today we will creating a dynamic photo gallery using Jquery in PHP, Mysql.

Most of the time when creating email template in PHP , we may need to separate some files and include these .
But including these files with shorthand cause some display problem .
<?=include('includes/header.php');?>
Well, short tags are used for simple variable output and not a piece of HTML .
So we have to use like below .
Short tags were, for a time, the standard in the PHP world; however, they do have the major drawback of conflicting with XML headers and, therefore, have somewhat fallen by the wayside .
In our experience most servers do have short tags enabled.
<?=
is far more convenient than typing
<?php echo
From PHP 5.4.0 the short_open_tag mandate does exclude the short echo tag ! This is essential as the utilization of all other short echos is viewed as vain. In any case the utilization of the short echo tag is supported starting now and into the foreseeable future. It provides for a smoother and tidier code-base – esp. in view documents. So for PHP >= 5.4.0 can be utilized without setting short_open_tag. Kindly don’t utilize the other short tag in your code .

Pagination is very important part in any web project .Because all large records of items can’t load in a single page . We require pagination to show these items in multiple pages . Well Jquery,Ajax pagination enhance user experience on your website . So, today i am writing tutorials onPHPpagination with Jquery,Ajax.
We will use PHP to fetch post from Mysql database with pagination . Jquery,Ajax will do the work for loading records according to pagination click without page reloading .
We should have below files before starting any work .
We have to create a table ‘posts’ to store records , Find below sql code to create ‘posts’ database table .
CREATE TABLE `posts`(`id`int(11) NOT NULL AUTO_INCREMENT,`title` varchar(255) COLLATE utf8_unicode_ci NOT NULL,`content` text COLLATE utf8_unicode_ci NOT NULL,`created` datetime NOT NULL,`modified` datetime NOT NULL,`status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '1=Active, 0=Inactive',
PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
Pagination Class
We have created a paginator class to show pagination . Find below some basic configuration in this class that you can customize as per your requirements .
baseURL – baseURL holds the URL to send Ajax request . totalRows – Total number of records. perPage – How many records you want to display on per page. contentDiv – Give the ID of the element where the pagination data would be displayed.
This file contains some Jquery, PHP, and HTML code. Full script of index.php file have mentioned separately below.
Jquery: Include the jQuery library to working with jQuery and Ajax. Also, some jQuery would require for show and hide loading overlay at the time of Ajax request.
<scriptsrc="jquery.js"></script><scripttype="text/javascript">// Show loading overlay when ajax request starts
$( document ).ajaxStart(function(){
$('.loading-overlay').show();});// Hide loading overlay when ajax request completes
$( document ).ajaxStop(function(){
$('.loading-overlay').hide();});</script>
PHP & HTML :
With the pagination links, will will display limited no. of records . To display the pagination links, you have to create an object of the Pagination class. Also, you can pass the configuration of the pagination links within Pagination class. Call the createLinks() function of the Pagination class to displaying the pagination links.
<divclass="post-wrapper"><divclass="loading-overlay"><divclass="overlay-content">Loading.....</div></div><divid="posts_content"><?php
//Include Pagination class file
include('pagination.php');//Include database configuration file
include('config.php');
$limit =10;//Get the total number of rows
$queryNum = $db->query("SELECT COUNT(*) as postNum FROM posts");
$resultNum = $queryNum->fetch_assoc();
$rowCount = $resultNum['postNum'];//Initialize Pagination class and create object
$pagConfig = array('baseURL'=>'getData.php','totalRows'=>$rowCount,'perPage'=>$limit,'contentDiv'=>'posts_content');
$pagination =newPagination($pagConfig);//Get rows
$query = $db->query("SELECT * FROM posts RDER BY id DESC LIMIT $limit");if($rowCount >0){?><divclass="posts_list"><?php
while($row = $query->fetch_assoc()){
$postID = $row['id'];?><divclass="list_item"><ahref="javascript:void(0);"><h2><?php echo $row["title"];?></h2></a></div><?php }?></div><?php echo $pagination->createLinks();?><?php }?></div></div>
get_data.php File
This page called by Ajax. Here We’ll get the page number of the pagination link and fetch the respective posts data.
query(“SELECT COUNT(*) as postNum FROM posts”); $resultNum = $queryNum->fetch_assoc(); $rowCount = $resultNum[‘postNum’];
//initialize Pagination class $pagConfig = array(‘baseURL’=>’getData.php’, ‘totalRows’=>$rowCount, ‘currentPage’=>$start, ‘perPage’=>$limit, ‘contentDiv’=>’posts_content’); $pagination = new Pagination($pagConfig);
//get rows $query = $db->query(“SELECT * FROM posts ORDER BY id DESC LIMIT $start,$limit”);
if($rowCount > 0){ ?>
fetch_assoc()){ $postID = $row[‘id’]; ?>
createLinks(); ?>
CSS (style.css)
Below css used for pagination links layout , you can customize it as per your website designs.
