It has saved over 435 billion Web pages, which probably isn’t all the content on the Internet.

Steps to access old, deleted web pages on Internet are here:

• Open website of Wayback Machine i.e. www.archive.org.
• Enter the URL of the website that you want to access in the search box on the top of the website.

1. Open the search engine you like. Google’s caching is very good, so we suggest you use it.
2. Paste the link of the missing webpage in the search bar if you know it, or just search for the page to find the link you need.
3. Under the blue text of the link, you’ll see a line of green text, which is the URL of the webpage. Click the down arrow next to the green URL text.
4. Click Cached. This will show you a saved version of the page you wanted, along with details of when the backup was made.
5. If this page does not load properly, you can try clicking the Text-only version on the top right side. This will lose all images that were on the page, but if it isn’t loading correctly, this will still let you get to the important data you needed.

As I have told you two ways to get your old data or webpages. WayBack Machine can provide you more than 1,2 or 5-year-old data but search engine cache can only provide a few days back data. So, It’s on your requirement how you need to use this.

Today we will see how we can do an embedded signing with DocuSign in Core PHP or any Other. If you are reading my blog which means you also want to integrate DocuSign with your Application. Please follow the below instruction to integrate DocuSign in one shot.

Step: 1 Create a developer account on DocuSign

I Know, You that stuff very well and you already your DocuSign developer account. But dude let me clear few things for you that will help you to understand the DocuSign API and structure.

Credits: codeHunger

Here, You need to create APP Like DemoApp for your project. Account id, Integration key ( Client_id / ds_client_id), Secret Key and Refer Url. These 3 things are very necessary.

Suggestion: I personally Suggest you to create ds_config.php file with all configuration constant to handle the whole API.

Step: 2 Create an DocuSign Folder on Xampp.

create a folder in your Xampp or Server. here, I also suggest, test on xampp and than use composer. if you don’t know about don’t worry just follow my steps.

First install composer from https://getcomposer.org/download/. than you need to install DocuSign Library using Command.

after installing composer, open your in the right folder for docusign.

Step: 3 Install DocuSign Package

Composer require docusign/esign-client

After this Command, you have vendor folder which contain packages, src folder which contain our Base Class which handle all API, and doc folder contain PDF file which need to signature. and index.php file is base file which can be Laravel routes, CodeIgniter routes or controller,  or any file which handle routes. and ds_config.php as i already told you above.

suggestion: you can use .env in replacement of ds_config if you are using Laravel or any other framework.

Step: 4 Collect all code and Files as Given below

index.php file code:

<?php 

require_once dirname(__FILE__). '/ds_config.php';
require_once dirname(__FILE__). '/src/DocuSignController.php';

$docuSign = new DocuSignController();

if (session_status() == PHP_SESSION_NONE) {
    session_start();
}

$authData = @$_SESSION['authData'];
if(@$_GET['page']=='connect'){
   $docuSign->connect(); 
}elseif(@$_GET['page']=='sign'){

   $docuSign->signDocument();
}
else{
  if(@$_GET['code'] && ( !array_key_exists('authData',$_SESSION) || property_exists($authData,'error') )){
        $docuSign->callback();
  }
  //session_destroy();
  $docuSign->index();
}
?>

Src folder code and structure:

Here in src folder, we have 2 files one is index.php ( view ) and another DocuSignController.php Class which contain all API. In CodeIgniter you can use it as custom library, in Laravel you can use it as Controller or Service.

So, Here Index.php ( view ) code:

} // end of class

After connect, if everything is correct than you will get code variable in url. and than click on sign document. after this you need to authorized DocuSign with admin account details.

I hope, this blog helps you to install docuSign. at time i was so confused with docuSign documentation and git code examples. but now you have everything.

You can also download DocuSign API code from my Github

This problem comes when you are using the Nigix Linux server or Apache Linux server. and also your project is in a subdirectory Like: /var/www/example.com/app  or  /var/www/html/app.

As you Codeigniter routes working .htaccess file and the problem is also here. but changing anything related to the .htaccess file you need to answer few things.

My CodeIgniter config.php file should like given below:

$base_url   = (isset($_SERVER['HTTPS']) ? "https://" : "http://").$_SERVER['HTTP_HOST'];
$base_url  .= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
$config['base_url'] = $base_url;
$config['indexpage’] = “;
$config['uri_protocol’] = 'REQUEST_URI’;

My CodeIgniter .htaccess file should be like given below:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUESTFILENAME} !-f
RewriteCond %{REQUESTFILENAME} !-d
RewriteCond $1 !^(index.php|assets|upload|robots.txt|..css)
RewriteRule ^(.)$ index.php?/$1 [L]

So, if this is all good with your project that means your code and .htaccess file is good and you need to access the server terminal or server, support team.

Also, read about the top richest Indian blogger and how to earn money via blogging.

For Apache Linux server:

I believe that you need to enable AllowOverride in order for your .htaccess to take effect.

To do that you need to add the following in your Vhost:

<Directory /var/www/learnphponline.in/app>
   Options Indexes FollowSymLinks
   AllowOverride All
   Require all granted
</Directory>

Note:- that you need to update the /var/www/learnphponline.in/public part to match your document root. Then run a config test and restart Apache. After that, the rules that you have in your .htaccess file would take effect.

For Nginx, PHP-FPM:

find the file nginx.conf and add this code:

location / {
    # nginx won't display 404, we leave this to Rails
    try_files $uri @passenger;
}

location @passenger {
   passenger_app_root /var/www/learnphponline.in/;
   passenger_document_root /var/www/learnphponline.in/app/;
   passenger_enabled on;
}

Summary for the CodeIgniter routing problem

Hope this will help you or at least you get an idea of what issue you are facing. Migration from one server to another or from localhost to live server will create this kind of issue. But if you have proper support from the server team or admin then it will be very easy for you to solve this.

It is not very complex but sometimes very essential when we need the latest version of PHP for a new project without changing the current local server settings. So, I am trying to cover changing the version by keeping the old version manually.

Latest Version of PHP in 2021

Now we have the PHP 8.0.2 version and more latest versions will be on the way. And PHP 8 has many features as given below.

• PHP 8.0 is a major update of the PHP language.
• It contains many new features and optimizations including named arguments, union types, attributes, constructor property promotion, match expression, null safe operator, JIT.
• PHP 8 has improvements in the type system, error handling, and consistency.
• PHP 8.0 improves speed and compiling.

Now, I am going to tell you How to Upgrade PHP Version 7 to 8 in Xampp

Step1: Download PHP 8.0.2 Version from its official website. click to download PHP 8.0.2.  You need to download Thread safe version.

after download the PHP latest version. you need to create a new folder named “php” and extract the downloaded zip inside the PHP folder you recently created.

Step 2: Go to your XAMPP installation directory ( C:\xampp\php ) and rename your old PHP directory with an old version prefix like PHP to PHP_old or PHP_7_4. Now copy & paste the extracted new PHP folder here. You can see this in the given image below. I have changed my PHP folder name to php7.2. and the PHP folder is the latest version.

Step 3: After the rename of the old php folder to php7.2 or something else. Now you need to move the new “php” to xampp directory.

Step4: Next, open httpd-xampp.conf from the XAMPP dashboard configuration panel. as you can see in the given below image.

On the PHP-Module setup section, comment these two lines and add the two lines below

#
# PHP-Module setup
#
LoadFile “/xampp/php/php8ts.dll”
LoadFile “/xampp/php/libpq.dll”
LoadModule php_module “/xampp/php/php8apache2_4.dll”
LoadFile “C:/xampp/php/libsqlite3.dll”

That’s it. Now restart your XAMPP server and keep coding. Now you can check your php version via using the php_info() function or you can also use the command: php -v

Summary for Upgrade PHP Version 7 to 8 in Xampp

May in some cases you will face an error or issue. so, I recommend you restart your system once and check it again. if the error is still there or Xampp apache is not running so, you have 2 scenarios.

1. Your PHP new version does not download or extracted correctly. or you have downloaded the wrong zip file.
2. you did a mistake in the editing of httpd-xampp.conf file.

Updating WordPress is just a 20-second task and it takes me 3 days. so, finally, after so much research I got my solution and now I will share it with you.

Diagnosing the “Installation Failed: Could Not Create Directory.” Error in WordPress (2 Methods)

The good news about this error is that it’s relatively easy to fix. Most of the time, correcting your permissions will clear everything right up. Before you start work on that solution, however, you may want to make sure that it can actually solve your problem.

Below, we’ve outlined two methods for determining whether your site is experiencing a permissions-related error.

1. Use the WordPress Site Health Tool
2. Check Your Server’s Error Log

So let’s discuss why this issue (Unable to Update WordPress) comes?

As I observed the issue very deeply and I found a few main issues are given  below:

1. WordPress files or directory is missing. You can download WordPress manually and add the missing file or replace the whole directory.
2. WordPress files or directory permission should not be as per guidelines. you can download WP Security Plugin and go to the file system security page to check files and directory permissions.

   

3. if you tried both methods given above then definitely you are using Dedicated Linux Server (Redhat, Centos, or any other). So in this case you need to update your directory user and its group. sudo chown -R apache:apache /path/to/WordPress.

This command will help you. for Linux servers, you can use this command as given below.

sudo chown -R apache:apache /var/www/html/WordPress

Here, the WordPress means your directory if your WordPress is in the main directory then remove the “WordPress” word from the end. this will update your user and group from root to apache. after this command, you can check file and directory status by ls -l  command.

after this command now you can try again to update WordPress from your admin panel. if you again failed that means you have an issue as I had.

Errors on your WordPress site can slow down your work and create serious inconveniences for both you and your users. For instance, the “Installation failed: Could not create directory” message can prevent you from providing a key feature or functionality.

Now Please follow my steps very carefully and I am expecting that you tried all ways given above. So, Here you need to only 2 last commands for this problem.

The final way to solve this issue “Unable to Update WordPress”:

Let’s get started! just enter the command given below to check your files. It’s again the “Ls” (Listing) command.

ls -Z /var/www/html/path_to_your_website_folder/

After this command, you will get the result given below. if you saw the same something is this. that means your user and group is apache: apache.

Now step 2  is run the command again given below:

chcon -R --type httpd_sys_rw_content_t /var/www/html/rr/path_to_your_website_folder/

So, After this command, your WordPress will upgrade to the latest version. I hope my blog will be helpful to you. Please share this on social media so it will rank high for others. You can also read about, How to earn money with any investment. and Top freelancing languages.

Summary for Unable to update WordPress to the latest version.

Here, sometimes Linux terminals without full knowledge will be tough for any developer. So, I recommend getting some knowledge about Linux basic commands in your free time. WordPress has many security loops and I personally recommend you to make your WordPress website secure with security plugins like Wordfenece or WP security.
