Facebook style profile photo upload + Resize Image + Saving into database


Introduction:

My last article was “How to build Facebook style profile photo upload using PHP + JQuery + Ajax Part1”. . This is continuation of my last article, last tutorial I show you how to upload profile picture using jquery, ajax, in this tutorial I will show you how to create thumbnail to fit the profile picture and saving into database.

Profile Picture Upload and Thumbnail Creation:

To achieve this I am using Cygnite PHP framework, if you had built application already, would like to use tiny component rather than using entire framework, you can use standalone Cygnite File component for image uploading and creating thumbnail image.



In previous tutorial we already created controller, view and js files. Open apps/controllers/ProfileController.php, import namespace to include thumbnail component, and add below code after uploading the file upload success to generate thumbnail image. I am adding piece of code to upload, creating thumbnail image and saving into database below, you can update below code into our ProfileController.php uploadAction() as discussed in the part1 tutorial.



use Apps\Models\Profile;
use Cygnite\Common\File\Thumbnail\Image; // available in dev-master 
use Apps\Components\Thumbnail\Image; //available in v1.2.4


$status = Upload::process(function($upload)
{
    $upload->file = 'document'; // Your file input element name
    $upload->ext = array("JPG", "PNG"); // Add validation for image upload
    //$upload->size = '6144';// limit the size

    if  (isset($_FILES['document']))  {

        $fileArray = array();
        $fileArray = pathinfo($_FILES['document']['name']);

        if ($upload->save(array("destination"=> "upload",  "fileName"=>$fileArray['filename'])) ) {

            // Create thumbnail object
            $thumb = new Image();
            $thumb->setRootDir(CYGNITE_BASE);
            $thumb->directory = 'upload/'.$_FILES['document']['name'];
            $thumb->fixedWidth = 100;
            $thumb->fixedHeight = 100;
            $thumb->thumbPath = 'upload/thumbnail/';
            $thumb->thumbName = $fileArray['filename'];

            if ( $thumb->resize() ) {

                // Save profile information into database
                 $profile = new Profile();
                 $profile->name = 'Sanjoy Dey';
                 $profile->original_image_path = CYGNITE_BASE.'upload/';
                 $profile->image = $_FILES['document']['name'];
                 $profile->thumbnail_image_path = CYGNITE_BASE.'upload/thumbnail/';
                 $profile->save();
            }

            $response= array('status' => true, 'msg' => 'Profile Picture Uploaded Successfully!' );
        } else {
            $response = array('status' => false, 'msg' => implode(', \n', $upload->getError()) );
        }
        header('Content-type: application/json');
        return  json_encode($response);
    }
});

echo $status ;



We are storing the thumbnail image into /cygnite/upload/thumbnail/ directory and saving into table 'profile'.

We will save the thumbnail image path and original image path into database as above. let me assume you have already set database connection into apps/configs/database.php

If you are building session based application. You can simply check user session id to identify user profile image and display it.

Using Standalone Cygnite File Thumbnail Component for creating thumbnail image:

If you are using standalone file thumbnail component to create thumbnail image (Discussed in previous post) than install file component from composer repository and below code to resize.


 require 'vendor/autoload.php';

 use Cygnite\Common\File\Thumbnail\Image;


 $thumb = new Image();
 $thumb->setRootDir(getcwd());
 $thumb->directory = getcwd().'/upload/profile-picture.jpg';// your dynamic image path
 $thumb->fixedWidth = 100;
 $thumb->fixedHeight = 100;
 $thumb->thumbPath = 'upload/thumbnail/';
 $thumb->thumbName = 'profile_thumbnail_image';
        
 if ( $thumb->resize() ) {
    // success
 }

Facebook style profile picture upload using PHP + JQuery +Ajax Part1


Introduction:

Hello Friends! 

In the last article we talked about “How to build Facebook style Autocomplete using Angular JS, Cygnite PHP, Mysql and Bootstrap template” . Recently I received a request from one of my reader that “How to build Facebook style profile photo upload, creating thumbnail and save into server ?”. I will write the same here today. You might have notice in many social network site, in profile page when you mouseover in your photo "Update Picture" or "Upload Photo" displays. It's looks cool, as it is not displaying such old type of file upload html element. In this post I will not be able to cover whole tutorial. So I decided to divide the post into part. In this tutorial I will tell you the best way to make "Facebook style profile photo upload using PHP, JQuery and Ajax."

To build this app, I am using Cygnite PHP Framework, JQuery, Ajax, Bootstrap template etc. Using framework make my job easier (Since bootstrap theme, inbuilt libraries, MVC, Widget etc), well structured, also gives flexibility to maintain code. If you don't wish use entire framework you can also use Cygnite File Component to do the same.

Installing Composer and Cygnite Framework:

So the first step is to install Cygnite framework to build our application, I am not going to write "How to install Cygnite PHP Framework", as it has covered in my previous article. Below links for Installation of Cygnite Framework but Cygnite v1.2.4 doesn't include File Upload feature, so please update composer.json to download latest framework code (dev-master) or manually update the framework core.

Cygnite Framework- Composer Installation

Manual Download from GITHUB

  Live Demo   Download

Step 1:
Let me consider you have already Cygnite installed into your machine. I have installed it into /www/cygnite/ directory. Now create a controller called ProfileController.php into your /cygnite/apps/controllers/ProfileController.php.

We will render the default view page using indexAction. We are not using layout here, but you can also use layout to make your view page much modular, flexible. Paste below code into your controller to call your view page.

 


namespace Apps\Controllers;

use Cygnite\Foundation\Application;
use Cygnite\Mvc\Controller\AbstractBaseController;
use Apps\Models\Country;
use Cygnite\Common\File\Upload\Upload;
use Cygnite\Common\UrlManager\Url;
use Cygnite\FormBuilder\Form;

class ProfileController extends AbstractBaseController
{
   protected $templateEngine = false;

   //Plain PHP layout
   //protected $layout = 'layout.base';
  /*
   * Your constructor.
   * @access public
   *
   */
   public function __construct()
   {
      parent::__construct();
   }

  /**
   * Default method for your controller. Render welcome page to user
   * @access public
   *
   */
  public function indexAction()
  { 
     $this->render('index');
  }


   // Upload profile picture
  public function uploadAction()
  {
    $status = Upload::process(function($upload)
    {
        $upload->file = 'document'; // Your file input element name
        $upload->ext = array("JPG", "PNG"); // Add validation for image upload
        //$upload->size = '6144';// limit the size

        if  (isset($_FILES['document'])) {

            if ($upload->save(array("destination"=> "upload",  "fileName"=>"user_profile_".time()))) {

                $response= array('status' => true, 'msg' => 'Uploaded Successfully!' );
            } else {
                $response = array('status' => false, 'msg' => implode(', \n', $upload->getError()) );
            }

            header('Content-type: application/json');
            return  json_encode($response);

        }
    });

    echo $status ;
  }
}


Step 2:
When you create a new controller you also need to create a folder into views/ as same name as controller but lowercase inside /cygnite/apps/views/ directory. I am creating my view page called index.view.php inside /apps/views/profile/index.view.php and paste below code to render our profile default image.



<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="col-sm-9">
    <form enctype="multipart/form-data">
        <div id="profile">
         <a href="javascript:void(0);">
             <img src="<?php echo Url::getBase(); ?>/assets/img/no_image.jpg" class="profile-image"  id="profileImg"/>
               <span id="uploadTrigger"><b>Update Picture</b></span>
               <input name="document"  type="file"  id="file-id" class="active"/>
             </a>
        </div>
        <div style="top:2px;"> </div>
        <div id="status_msg"> </div>
    </form>

</div>

Step 3:
Create a js file called profile.js into cygnite/assets/js/profile.js and paste below code. Cygnite is shipped with bootstrap so you can use it or use cdn link.



$(document).ready(function () {

    $("#uploadTrigger").on('click', function(event) {
        $("#file-id").trigger('click');
    });

//$('.hidden').removeClass('hidden').addClass( 'active');

$(":file").change(function() {

    var file = this.files[0],  name = file.name, size = file.size, type = file.type;
    //Your validation
    var imageType = new Array("image/png","image/jpeg", "image/gif", "image/bmp");

    if(jQuery.inArray(type, imageType )  == -1) {
        $("#status_msg").html("Valid file formats are: jpg, jpeg,png, gif").css('color', '#F00000');
        return false;
    }  else {

        $("#status_msg").html(" ");
        if ($("#file-id").val() !== '') {
            var formData = new FormData($('form')[0]);

            $.ajax({
                url: 'upload',  //Server script to process data
                type: 'POST',
                //Ajax events
                beforeSend: function () {
                    $('#profileImg').addClass( 'profile-image-loading')
                                    .removeClass('profile-image')
                                    .attr('src', '/assets/img/fb_loading.gif');
                },
                success: function (data) {

                    if (data.status) {
                        var reader = new FileReader();
                        reader.onload = function (e) {

                        $('.profile-image-loading')
                            .addClass('profile-image')
                            .removeClass('profile-image-loading')
                            .attr('src', e.target.result);
                           return false;
                        }
                        reader.readAsDataURL(file);

                        $("#status_msg").html(data['msg']).css('color', '#009900');
                    } else {
                        $("#status_msg").html(data['msg']).css('color', '#F00000');
                        return false;
                    }
                },
                // Form data
                data: formData,
                //Options to tell jQuery not to process data or worry about content-type.
                cache: false,
                contentType: false,
                processData: false
            });
        } else {
        alert("Please select valid image.");
        return false;
        }
        }

});

});


Using Standalone Cygnie File Component for File Upload:

If you have already built an application and willing to use only standalone file component you can simply install Cygnite/File component using composer. I have installed composer globally in my system.

Create a composer.json file into your root directory where you want to install component, paste below code and save it.


{
  "require": {
    "php": ">=5.4.0",
    "cygnite/file" : "dev-master"  
  },
  "autoload": {
    "psr-0": {
        "Cygnite\\Common\\File": "cygnite/file/"
     }
   }
}


Now open terminal/command prompt, change to your project directory where composer.json exists and issue below command to install File Upload Component to do the same stuff.



composer install 


I am creating index.php file to access Cygnite File component, and below code to access File Upload feature.




require 'vendor/autoload.php';

use Cygnite\Common\File\Upload\Upload;

$upload = new Upload();

//$upload->setUploadSize(62092);
$upload->file = 'document';
$upload->ext = array("JPG");
$upload->size = '1024';

if(isset($_FILES['document'])) {

    if ( $upload->save(array("destination"=> "upload", /* "fileName"=>"demo_icon","multiUpload"=>true*/)) ) {
        $response = json_encode(array('status' => true, 'msg' => 'Uploaded Successfully!' ));
    }  else {
        $response = json_encode(array('status' => false, 'msg' => $upload->getError() ));
    }

    echo header('Content-type: application/json') .$response;exit;
}


Or you can also use Closure beautiful syntax as below.



require 'vendor/autoload.php';

use Cygnite\Common\File\Upload\Upload;

function fileUpload()
{
    $status = Upload::process( function($upload)   {
        $upload->file = 'document';
        $upload->ext = array("JPG");
        $upload->size = '5000000';

        if  (isset($_FILES['document'])) {

            if ( $upload->save(array("destination"=> "upload",  "fileName"=>"demo_".time(),/*"multiUpload"=>true*/)) ) {
                $response= array('status' => true, 'msg' => 'Uploaded Successfully!' );
            }  else {
                $response = array('status' => false, 'msg' => implode(', \n', $upload->getError()) );
            }

            header('Content-type: application/json');
            return  json_encode($response);
        }
    });

    echo $status ;
}


Now you can call the fileUpload function as usual in core php and calling this method in ajax url will process your ajax file upload. Don't forget to Include all above necessary css and jquery files in order to make the app work.

Finally go to browser and call the application by issuing below url.



http://localhost/cygnite/index.php/profile/

Facebook style wall posting using Cygnite PHP Framework, Jquery, Ajax


Introduction:

The last article was about “Reading and importing CSV file into database using PHP” . Today I have interesting thing for you guys. Are you looking for social script as facebook comment posting with MVC architecture? Which contains share thoughts on wall, comment posting, delete using jquery, load more, ajax, you want to share Facebook like video. You may get many script from different sites but mostly paid and not modular MVC architecture and you will end up restructuring into MVC. So I thought to share with you the application where you will find all these features and many more on coming days. Also you can find the script hosted on GITHUB.

Step 1:

Download and extract (wallscript-master.zip) the code from GITHUB. Rename wallscript-master to wallscript.

Step 2:

Configure your database name into /wallscript/apps/configs/database.php. I have configured database: “tutorials” localhost with empty password, you can change if you have different.

Step 3:

Find the demo sql script inside /wallscript/apps/database/wallscript.sql. Run the sql file into your database using phpmyadmin or Mysql Workbench.

Step 4:

That's all. You are done. Now go to your browser and type url : http://localhost/wallscript/ You can see the screen as below.


Extract video from url:



 

Conclusion:

Hope this small application is useful. You may alter the script to build much more features like Facebook or any other social network. 

If you are finding this tutorial helpful, please don't forget to share with friends, also leave your comments below. Have a nice day. Keep visiting for interesting articles.


Auto reload page content every 3 sec using JQuery, Ajax & PHP


Hello Friends!

Did you read my last blog “How to auto resize textarea based on the user input?”

If you have noticed that the Facebook/Twitter social networking sites repetitively search for new comments/tweets to display to the end user. It is pretty simple concept, which we can achieve using a simple script. It is approx. 10 lines of code. 

I thought this may be helpful for newbie and here I am going to write about "How to auto reload partial page and display number of tweets" with very few steps.

Step 1:

Create a index.php file and paste below code into it. Don't forget to include Jquery and Ajax framework in your page.


  
  
  $(document).ready(function(){ 
   var auto= $('#tweets'), refreshed_content;	
       refreshed_content = setInterval(function(){
        auto.fadeOut('slow')
            .load("result.php?id=123").fadeIn("slow");
            }, 3000); 										
    console.log(refreshed_content);										 
    return false; 
  });
  

Above script will call result.php page on every 3 seconds and fetch the number of tweet count. Replace id=123 with logged in user id. Next we are going to place a div where tweets count will get displayed. 


<div class=”container”>
<div id="tweets"> </div> 
</div>

Now let us create result.php to perform twitter live search and return the tweet count to the user. Copy  below piece of code and paste it into result.php to perform live database search. Here user_id is referred to the logged in user id to search against the database.


$userid = (string) (isset($_GET['id'])) ? $_GET['id'] : '';

$link = mysql_connect("localhost", "root", "");
mysql_select_db("twitter", $link);
$sql = "Select * FROM user_tweets where user_id = '$userId' ";
$result = mysql_query($sql, $link);
$num_rows = mysql_num_rows($result);

echo "Total $num_rows new Tweets ";exit;


That’s it. We are done. 

This small script will automatically fetch the number of tweets on regular interval and display to end user. You may modified this script accordingly to create a live notification system. 

Hope it will be helpful. Please do not forget to leave your comment below & share with friends.



How to populate a select box using jQuery ajax json, php?





Hello Friends! With the help of Ajax and PHP you can easily populate a select box without refreshing the page. You can also do it using only PHP script but requires you to refresh the page every time you change the select box value. Here is a very simple and useful example how you can populate a select box without refreshing page.

Prerequisites

1. Latest version of JQuery.

2. Very basis understanding of JSON.

3. A server side scripting knowledge to respond to Ajax request. In this tutorial I am going to use PHP as a scripting language.

Code:

There are 4 parts in this DEMO.

HTML page

The JQuery & Ajax (Client side code)

JSON structure

Server side code to populate dynamic page.

HTML:


  <select id="category">

      <option value=""> Select Job Type</option>

      <option value="1">Technical </option>

      <option value="2"> QA </option>

  </select>

 <select id="sub-category">

      <option value=""> Select Area Lead</option>

  </select>


JQUERY & AJAX REQUEST:

Include latest version of Jquery in your HTML page. Below ajax script will call server side script to get JSON data and populate select box. Add below script in your page.

 


$(function(){ 
    $('#category').change(function() {
        
        $.ajax({
            type: "POST",
            url: 'https://appsntechinfo.com/demo/list_ajax',
            data: {'categoryID': $(this).val(),'isAjax':true},
            dataType:'json',
            success: function(data) {

               var select = $("#sub-category"), options = '';
               select.empty();

               for(var i=0;i<data.length; i++) {
                 options += "<option value='"+data[i].id+"'>"+ data[i].name +"</option>";              
               }

               select.append(options);
            }
        });
    });
});


And now in your server side page you may write below to fetch data from database.

SERVER SIDE SCRIPT:

We will first validate the category id and fetch data from database then return JSON response to UI.

 

if (isset($_POST['categoryID'])) {

    $id = trim($_POST['categoryID']);
    $result = array();
    $id = mysql_real_escape_string($id);
    $res = mysql_query("SELECT * FROM sub_categories WHERE category_id = $id");
    while ($row = mysql_fetch_array($res)) {

    $result[] = array(
      'id' => $row['subcatid'],
      'name' => $row['description']
    );

    }

    echo json_encode($result);
}

SAMPLE JSON:

 

[
  {"id":10, "name": "Anderson"},
  {"id":11, "name": "Shane"},
  {"id":12, "name": "Shelly"}
]
