Replace mcrypt_encrypt with openssl_encrypt

Simple Example :

$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $this->key, $input, MCRYPT_MODE_CBC, $iv);

$encrypted = openssl_encrypt($input, 'AES-128-CBC', $this->key, OPENSSL_RAW_DATA, $iv);

How to Setup Virtual Host in Windows

Step: 1

Create the Virtual Host

First, you need to navigate to D:\wamp64\bin\apache\apache2.4.27\conf\extra or wherever your WAMP files are located.

Then, edit httpd-vhosts.conf with any text editor. In my case, I am using Notepad++.

<VirtualHost lawrawel.samweb.com:80>
  ServerName lawrawel.samweb.com
  #ServerAlias localhost
  DocumentRoot "${INSTALL_DIR}/www/lawrawel_sep/sam_web"
  <Directory "${INSTALL_DIR}/www/lawrawel_sep/sam_web/">
    Options +Indexes +Includes +FollowSymLinks +MultiViews
    AllowOverride All
    Require local
  </Directory>
</VirtualHost>

#VirtualHost: Most web servers use port 80 as their default port. However, you can change the port to 8080, 8081 etc.
#DocumentRoot: The folder where files of a site will exist. In our case, the folder name is “sam_web”.
#ServerName: It is the URL for our virtual host.
#Directory: It is the directory of our virtual host.

Step: 2

Create the Host

Now, go to "C:\Windows\System32\drivers\etc\hosts"

Next, open Host file in your text editor.

Add the following line in the Host file.

127.0.0.1 lawrawel.samweb.com

Step: 3

#After you have done all the steps, restart wampserver for the configuration to be set.

#Open a browser and navigate to "lawrawel.samweb.com" You should see your website.

That’s it you have a running virtual host.

How to Calculate Time Difference in PHP

<?php
$start  = date_create('1989-04-01');
$end  = date_create(); // Current time and date
$diff   = date_diff( $start, $end );

echo 'The difference is ';
echo  $diff->y . ' years, ';
echo  $diff->m . ' months, ';
echo  $diff->d . ' days, ';
echo  $diff->h . ' hours, ';
echo  $diff->i . ' minutes, ';
echo  $diff->s . ' seconds';
// Output: The difference is 28 years, 5 months, 19 days, 20 hours, 34 minutes, 36 seconds

echo 'The difference in days : ' . $diff->days;
// Output: The difference in days : 10398

How to Send Email with Attachments via PHPMailer in WordPress

It is the PHP class which allows you send emails. Very simple I think. Let me tell you about attachments and show some examples.

So, first of all — if you want to attach something to the email, use the following pattern:

$phpmailer->AddAttachment('path to file', 'file name with extension');


Full example:


global $phpmailer; // define the global variable
if ( !is_object( $phpmailer ) || !is_a( $phpmailer, 'PHPMailer' ) ) { // check if $phpmailer object of class PHPMailer exists
// if not - include the necessary files
require_once ABSPATH . WPINC . '/class-phpmailer.php';
require_once ABSPATH . WPINC . '/class-smtp.php';
$phpmailer = new PHPMailer( true );
}
$phpmailer->ClearAttachments(); // clear all previous attachments if exist
$phpmailer->ClearCustomHeaders(); // the same about mail headers
$phpmailer->ClearReplyTos();
$phpmailer->From = 'misha@rudrastyh.com';
$phpmailer->FromName = 'Misha Rudrastyh';
$phpmailer->Subject = 'Plugin: ' . $plugin_display_name; // subject
$phpmailer->SingleTo = true;
$phpmailer->ContentType = 'text/html'; // Content Type
$phpmailer->IsHTML( true );
$phpmailer->CharSet = 'utf-8';
$phpmailer->ClearAllRecipients();
$phpmailer->AddAddress( $_POST['email'] ); // the recipient's address
$phpmailer->Body = '<p>Thanks for buying my plugin (the plugin archive is attached to this email).</p><p>If you have any questions, <a href="https://rudrastyh.com/contacts">contact me</a>.</p>';
$phpmailer->AddAttachment(getcwd() . '/plugins/' . $plugin_name . '.zip', $plugin_name . '.zip'); // add the attachment
$phpmailer->Send(); // the last thing - send the email

How to Book Appointment to Google Calendar

Step:1

Log into your Google Account, and then visit https://code.google.com/apis/console/. This will take you to a page that invites you to create a project with the Google API. Click on Create project….

Step:2

You are now asked to activate the services you wish to use. Click the button next to Calendar API to enable the calendar. You will be redirected to a page with a Terms of Service. Read and accept this.

Step:3

Now click on credentials ->Create credentials->OAuth client ID

Then click Next. 

Step: 4

Enter Name, Site domain and Authorized redirect URIs

Step: 5

You will be taken back to the API Access screen, with your new Client ID and Client secret. You will need this information to generate your Refresh Token, and to configure your application.

This page will also have your API key for ‘Simple API Access’. You will also need this API Key for your final calendar application.

Step: 6

<?php

$cScope         =   'https://www.googleapis.com/auth/calendar';

$cClientID      =   '';

$cClientSecret  =   '';

$cRedirectURI   =   'urn:ietf:wg:oauth:2.0:oob';

  

$cAuthCode      =   '';

if (empty($cAuthCode)) {

    $rsParams = array(

                        'response_type' => 'code',

                        'client_id' => $cClientID,

                        'redirect_uri' => $cRedirectURI,

                        'access_type' => 'offline',

                        'scope' => $cScope,

                        'approval_prompt' => 'force'

                     );

    $cOauthURL = 'https://accounts.google.com/o/oauth2/auth?' . http_build_query($rsParams);

    echo("Go to\n$cOauthURL\nand enter the given value into this script under \$cAuthCode\n");

    exit();

} // ends if (empty($cAuthCode))

elseif (empty($cRefreshToken)) {

    $cTokenURL = 'https://accounts.google.com/o/oauth2/token';

    $rsPostData = array(

                        'code'          =>   $cAuthCode,

                        'client_id'     =>   $cClientID,

                        'client_secret' =>   $cClientSecret,

                        'redirect_uri'  =>   $cRedirectURI,

                        'grant_type'    =>   'authorization_code',

                        );

    $ch = curl_init();

  

    curl_setopt($ch, CURLOPT_URL, $cTokenURL);

    curl_setopt($ch, CURLOPT_POST, 1);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $rsPostData);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //For Localhost only

    $cTokenReturn = curl_exec($ch);

    $oToken = json_decode($cTokenReturn);

    echo("Here is your Refresh Token for your application.  Do not loose this!\n\n");

    echo("Refresh Token = '" . $oToken->refresh_token . "';\n");

} // ends

?>

Before running this script, you will need to enter your Client ID ($cClientID) and Client Secret ($cClientSecret) as we found on the API page with Google. Once these values are added, run this script from the command line like this: php oauth-setup.php. You should see output like this:

Step: 7

samx@samx-desktop:~/code$ php oauth-setup.php 
Go to
https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=##########################&redirect_uri=###############&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar 

and enter the given value into this script under $cAuthCode

Step: 8

Visit the website, grant permission to access your resources, and then copy the code on this page. This is your auth code, and is normally good for 3600 seconds or so.

Enter this code into the oauth-setup.php script in the $cAuthCode variable. Then run the script again: php oauth-setup.php. You should see output like this

thomas@thomas-desktop:~/code$ php oauth-setup.php 
Here is your Refresh Token for your application.  Do not loose this!

Refresh Token = '#####################################';

Now, copy down the Refresh Token and save it for later. You will need it to make subsequent requests to Google to get a valid Auth Code for a transaction.

Stay tuned for Part 3 of the tutorial, which will use the above information to make calendar requests to Google. And allow us to create a web application that uses Google Calendar as a backend for a scheduling application.
