Yes. WordPress.com is safer than WordPress.org because WordPress.com has a community and a team which keeps a check on security standards. On the other hand, in WordPress.org you will be more reliant on your web hosting provider. If you are using WordPress.org you need to make sure that your host maintains a gold level security standards.

WordPress.com and WordPress.org are two different platforms with different approaches to security.

WordPress.com is a hosting service that provides users with a managed WordPress platform. In this case, security is managed by the WordPress.com team, who handles all the server maintenance, software updates, and security measures. WordPress.com also has strict security protocols, including SSL certificates, DDoS protection, and firewalls. They also monitor all sites on their platform for suspicious activity and malware.

This means that users are responsible for their own website's security, including server maintenance, software updates, and implementing security measures. While WordPress.org is secure, the level of security depends on the individual user's implementation of security measures.

So, in terms of security, WordPress.com may be considered more secure because the platform is managed by a team of experts responsible for maintaining security protocols. However, this also means users have limited control over their site's security measures. In contrast, WordPress.org gives users more control over their site's security measures but also requires them to maintain and implement those measures.

WordPress.com and WordPress.org are two different platforms that offer WordPress content management system (CMS) for creating and managing websites.

WordPress.com is a fully hosted platform that handles all the technical aspects of running a website, including hosting, security, and backups. On the other hand, WordPress.org is self-hosted, which means you need to find your hosting provider to host your website.

WordPress.com offers limited customization options and doesn't allow access to the website's core files. In contrast, WordPress.org offers full customization options, allowing you to modify the code and access the website's core files.

WordPress.com offers a limited number of themes and plugins to choose from, whereas WordPress.org offers an extensive library of themes and plugins that you can use to customize your website.

WordPress.com doesn't allow you to monetize your website with ads unless you upgrade to a paid plan. However, with WordPress.org, you have complete control over your website, including the ability to monetize it with ads and other methods.

WordPress.com offers various pricing plans, from free to premium plans with advanced features. In contrast, WordPress.org is free, but you must pay for hosting and other website-related services.

WordPress.com is a great platform for beginners who want an easy-to-use website builder. At the same time, WordPress.org is more suitable for advanced users who want complete control and customization options over their websites.

• Keep WordPress updated: WordPress regularly releases updates that address security vulnerabilities, so keeping your WordPress installation up-to-date is crucial to ensure the security of your site.
• Use strong passwords: Strong passwords include letters, numbers, and special characters. You can ignore easily guessable passwords such as "Your Name" or "123456".
• Limit Login attempts: This can help prevent brute force attacks. You can use a plugin like Limit Login Attempts Reloaded to limit the number of login attempts.
• Use a secure hosting provider: Choose a hosting provider that has a good reputation for security and provides SSL encryption.
• Use two-factor authentication (2FA): Two-factor authentication adds an extra layer of security to your site. You can use a plugin like Google Authenticator or Authy to enable 2FA.
• Use security plugins: Security plugins like Wordfence, Sucuri, or iThemes Security can help to identify and block potential security threats.
• Remove unnecessary plugins and themes: Unnecessary plugins and themes can pose a security risk. You should delete any plugins and themes you don't use.
• Regularly back up your site: Regularly backing up your site can help you restore your site in case of a security breach or a website crash.

By following these steps, you can significantly improve the security of your WordPress site.

To create a custom taxonomy in WordPress, follow these steps:

• Open the functions.php file in your WordPress theme's directory.
• Add the following code to register a new taxonomy:

  function custom_taxonomy() {
  $labels = array(
    'name'                       => 'Taxonomy Name',
    'singular_name'              => 'Taxonomy Singular Name',
    'menu_name'                  => 'Menu Name',
    'all_items'                  => 'All Items',
    'parent_item'                => 'Parent Item',
    'parent_item_colon'          => 'Parent Item:',
    'new_item_name'              => 'New Item Name',
    'add_new_item'               => 'Add New Item',
    'edit_item'                  => 'Edit Item',
    'update_item'                => 'Update Item',
    'separate_items_with_commas' => 'Separate items with commas',
    'search_items'               => 'Search Items',
    'add_or_remove_items'        => 'Add or remove items',
    'choose_from_most_used'      => 'Choose from the considerable used items',
    'not_found'                  => 'Not Found',
    'no_terms'                   => 'No items',
    'items_list_navigation'      => 'Items list navigation',
    'items_list'                 => 'Items list',
    'back_to_items'              => 'Back to items'
  );
  $args = array(
    'labels'                     => $labels,
    'hierarchical'               => true,
    'public'                     => true,
    'show_ui'                    => true,
    'show_admin_column'          => true,
    'show_in_nav_menus'          => true,
    'show_tagcloud'              => true,
    'rewrite'                    => array( 'slug' => 'taxonomy' )
  );
  register_taxonomy( 'taxonomy', array( 'post' ), $args );
}
add_action( 'init', 'custom_taxonomy', 0 );

• Save the functions.php file.
• Go to your WordPress admin panel and click on 'Posts' or 'Pages', depending on the post type you assigned your taxonomy to.
• Click on 'Add New' or edit an existing post/page.
• In the right sidebar, you should now see a box labeled with the name of your taxonomy. You can add new terms by clicking the '+ Add New Taxonomy' link.

That's it! You have now created a custom taxonomy in WordPress.

Here are the steps to successfully change the Homepage URL in Wordpress. Go to the function.php file in your WP theme and use this code:

function redirect_homepage() {
   if( ! is_home() && ! is_front_page() )
   return;
   wp_redirect( 'http://siteurl.com/news', 301 );
   exit;
}
add_action( 'template_redirect', 'redirect_homepage' );

We can do it 2 ways

• Before installation : Go to wp_config.php file and rename $table_prefix = 'wp_'; whatever you want.
• After installation : Go to phpmyadmin -> select your databse -> check all tables -> Add/Update table prefix.

$args = array( 'post_type' => 'blog', 'posts_per_page' => 10 );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
   the_title();
   echo '<div class="entry-content">';
     the_content();
   echo '</div>';
endwhile;

In Wordpress, an importer is a tool, which is used to migrate content from an existing WP website to another one. This tool can also be used to move a website from the localhost, i.e. local server to an online hosted server.

Using WordPress importer, you can migrate different data like:

• New Posts, pages, or other custom created post types
• Comments in posts
• Custom fields and post metadata
• Categories, tags, and other terms from custom taxonomies section
• Authors on the website

Custom posts types in WordPress are the new post types that developers can create. You can add a custom post type via the register_post_type() function, which allows the developers to define the new post type by labels, features, and availability.

Or we can also create custom post type with the helps of plugins.

• Custom Post Type UI
• Custom Field

Shortcodes in WordPress are specific codes that allow the developers to do various tasks with minimal effort. Shortcodes are used to simplify tasks such as creating objects or embedding files that require lots of coding in a single line. A Shortcode is synonymous to the shortcut. WordPress has five built-in shortcodes- audio, embed, caption, video, and gallery.

Yes. WordPress has all the tools and features to prevent any malicious attacks or brute force attacks on your website. All you need is to make sure you have completed these tasks given below.

Make a strong password and username for your WordPress admin login page and not only this, but the users which have been given editing permissions by you must also have strong passwords.

Having a good firewall can save you from trouble. It doesn't guarantee to eliminate brute force attacks but it can save you from malicious attacks. Make sure to have two-factor authentication or 2FA. WordPress will ask you for confirmation before login in either on your mobile or by email. There is a simple free plugin called Limit Login Attempts Reloaded which will limit the number of logins on your login page. And finally, Always keep your WordPress updated. WordPress brings all new security features on every update.

A Sidebar in WordPress is an area where widgets can be used with a theme and this area is also termed as a Widgetized area. In WordPress, sidebar is created by using a function named as register_sidebar() function. The widget zed area should be registered in WordPress supported the theme as they are presentational. The sidebar function takes only one argument of an associative array of parameters that set the options for the widget area. Wrap $args array and register_sidebar() both are separate functions that can be called on ‘widgets_init’ hooks. In short, with the use of register_sidebar() method/ function users can add sidebars to WordPress. Syntax code for the creation of sidebar-

$args = array(
   'name' => __( 'Sidebar name', 'theme_text_domain' ),
   'id' => 'unique-sidebar-id',
   'description' => '',
   'class' => '', 'before_widget' => '<li id="%1$s" class="widget %2$s">',
   'after_widget' => '</li>',
   'before_title' => '<h2 class="widgettitle">',
   'after_title' => '</h2>'

);

There are many ways when WordPress can interact with databases like using functions like get_posts(), wp_get_post_terms(), wp_query(), and $wpdb(). From all these functions the most effective function to get a database table out of WordPress is the $wpdb() function. $wpdb is a global function and hence is declared with global keyword.

global $wpdb;

Widget is defined as a configurable code snippet which makes it possible to customize the functionality and appearance of a WordPress blog. Users can access the widgets page form the appearance menu effectively. Widgets in WordPress allow you to drag and drop the elements into the sidebar of your website. WordPress is featured with a standard set of widgets that you can use with any theme of WordPress. In order to create a customer widget in WordPress, it is important for the customers.

• In order to create a site-specific plugin, paste the code functions .php file (theme’s file)
• add your code to appearance >> widgets pages
• register with ‘wpb_widget’ and load customer widgets

WordPress has many advantages but sometimes it can get costly for small businesses. This happens when you have a big website and less knowledge to even edit content.

WordPress, CMS requires regular maintenance every 2-3 months for which you need to hire a WordPress developer. These developers will make your website more of a code reliable than plugins reliable. When this happens you will not be able to customize and edit pages and content by yourself and hire more developers instead which will increase the cost of the project.

The second thing is when your website deals with a piece of sensitive information or you are worried more about your website's security, you should not use WordPress because it is prone to attacks by hackers. 1/3rd of all websites are created on WordPress and hence it becomes popular among hackers too since they have too many targets.

Here is a list of some best picks which we think will do the honors. Name any 3-4 and be sure to study about them in brief.

• Yoast SEO

A template tag <template> is a container that is used to store the hidden HTML syntax from the users while loading a page. You use it in JavaScript.

The extension of any parent theme present in WordPress is defined as a child theme. Any update to undo the changes in the child theme, if we make changes to the parent theme. While developers work on a child theme, the customizations and changes will be preserved on an update.

There will be two possible reasons:

First, you are not logged in to your wp-admin and see the sidebar without widgets. Second, you must have made some tweaks to your theme and that's why it's not showing up properly. The solution will be to deactivate and reactivate the theme and roll back to previous changes.

If the problem persists you need to reach out to the WP developer.

To enable debug mode in WordPress, developers have to edit the wp-config.php file and change the WP_DEBUG constant value to true condition.

This hacking situation is common nowadays. The more your website grows, the more chance it will have to be hacked. On starting a new website you need to know one sure thing which is, how to create a backup of your data and WordPress core files. Without this knowledge you can get rid of the hackers but with the cost of your data which is a nightmare for every admin. So always have a backup of your website's core files and the data. Now if you have that, the rest of the tasks are easy.

• Change the password immediately.
• Remove all the suspicious users and change all of their permissions to view content only. Talk to them and Change their passwords also.
• Run a good antivirus plugin and eliminate all the malicious and infected content.
• Update all your plugins, themes, or even WordPress.
• Clean your sitemaps.
• Reinstall your plugins, themes, and WordPress core.
• Remove the files which your antivirus can't remove and restore them with your backup file.
• Activate your firewall and antivirus for future attacks.
• Ask for third-party antivirus agencies if the damage is huge and you are unable to solve it on your own.

Permalinks are the permanent Full URLs to your website blog posts and pages, as well as your tag archives and category. It is the web address used to link to your content. WordPress allows us to create a custom URL structure for your permalinks and archives. It can improve the usability and forward-compatibility of your website's links.

This section can be located in

Settings → Permalinks

We can create templates for various purpose like if we want to make a different layout rather than a home page or if we want to display custom posts types like news than we can create a template and merely display all news there.

Steps to create template in wordpress themes.

• Create a news.php file on root in theme folder.
• Insert get_header(); and get_footer(); in news.php page
• Add in top of this created page. Now this template name is "News Template".

To make your static page as a front page you have to follow these steps

• Goto Admin Panel
• Select "A Static Page"
• Choose you page from "Front page" section
• Now your selected page from Front Page is set default front page.

It is provided by WordPress to allow your plugin to ' hook into' the whole WordPress; that is, to call functions in the plugin at particular times according to your need and thereby set your plugin in motion.

There are two kinds of hooks:

• Actions hook
• Filters hook

1. Actions Hook

Actions Hook are triggered by particular events that take place in WordPress such as changing themes, publishing a post, or displaying an administration screen. It is a custom PHP function defined in your plugin and hooked, i.e., set to respond, to some of these events.

Actions offently do one or more of the following things

• Modify database data
• Send an email message
• Modify the generated administration screen or front end page sent to a user web browser.

Here are some Actions Functions listed

• has_action()
• do_action()
• add_action()
• remove_action() etc

2. Filters Hook

Filters Hook are functions that WordPress passes data through, at certain points in execution, just before taking some action with the data. It sits between the database and the browser and between the browser and the database; all most all input and output in WordPress pass through at least one filter hook.

The necessary steps to add your filters to WordPress are listed:

• Create the PHP function that filters the data
• Hook to the screen in WordPress, by calling add_filter()
• Put your PHP function in a plugin file and activate it.

Here are some Filters Functions listed

• has_filter()
• doing_filter()
• add_filter()
• remove_filter() etc

wp_

In WordPress, Posts is a dynamic entity that has a published or updated date and is displayed on the blog page.

Example: news, events etc

Pages do not have published or updated date. Hence there are useful for the static and timeless type of content.

Example, the “About Us” or “Contact Us”

The difference between pages and posts is that the WordPress page is a static entity and post is a dynamic entity.

• Goto admin panel -> setting -> click on the Discussion tab
• Under Default article settings uncheck the box next to Allow people to post comments on new articles
• Now click on Save Setting

This function is used by developers to retrieve the metadata of users. The usermeta function is capable to return an array or single metadata. The following syntax needs to be used to apply usermeta function.

get_user_meta( int $user_id, string $key = '', bool $single = false )

Avatar or Gravatar is an icon or representation of a user in a shared virtual reality, such as chat, forum, website or any other form of online community in which the user wants to have something to distinguish themselves from other users.

It usually an 80px by 80px image that the user will create by ownself.

A category is one of the predefined taxonomies in WordPress, and it is used to sort and group content into different sections. In new WordPress installation, "Uncategorized" is the default category. We can change the default category from Settings -> Writing screen. In WordPress post can be filed under many categories and can have both tags and categories.

For Example

A tag is one of the pre-defined taxonomy in WordPress. You can add tags to posts along with categories in WordPress. Tags are smaller in scope and focused on specific topics.

To change the default length of the excerpt in WordPress, we have to insert the below-mentioned syntax to the functions.php file and edit the amount of the words that we desire to be displayed in our excerpts.

add_filter( 'excerpt_length', function($length) {
    return X;
} );

Here above X is the number of words to be displayed.

In WordPress categories are hierarchical which means terms can have a relationship with each other like child and parent.
Example: You could have a Category called India, and under India, you could have categories called Delhi, Haryana, and U.P. Categories means for broad grouping of posts.

But Tags are NOT hierarchical which means no relationship between them. Tags means to describe specific details posts.

We can make many types of user types of role.

• Administrator Role
• Author Role
• Editor Role
• Subscriber Role
• Contributor Role

With the method is_plugin_active() we can check any particular plugin is active or not.

How to check

include_once( ABSPATH . 'wp-admin/includes/plugin.php' );

if ( is_plugin_active( 'plugin-directory/plugin-file.php' ) ) {
   // Activated
}

• Activation and deactivation function creation
• The main plugin file creation and fill the header information
• Script for uninstall creation.
• readme.txt file creation
• Use of proper functions and constants to detect paths of the plugin file.

Yes, we can rename the WordPress folder. If WordPress is already installed in our device, we have to log in to the weblog as the administrator and the change the required settings mentioned below.

• WordPress address (URI)
• Blog address( URI)

After the changes, we can rename the folder or directory with the use of the WordPress file in it.

Users have to first ensure that whether the themes they are using support the widget they are wishing to add. In some cases, the problem may occur when the function.php or file similar to that is missing. There are chances also this could happen if the user forgets to save the changes made in the widget or to refresh the older page display.

echo get_site_url();

In order to include JavaScript file in WordPress, a special function can be used namely wp_enqueue_script (). In WordPress, the preliminary goal of wp_enqueue_script () is to add a JavaScript file which is one of the WordPress action hooks. In order to use the wp_enqueue_script (), users should need to add JavaScript to each page on the WordPress site.

You we use get_the_post_thumbnail_url(); . You can use this inside loop or outside loop. If you are using this outside of loop then you have to pass post ID otherwise its optional in case inside loop.

We can use has_post_thumbnail() method to check the featured image is exists or not.

Users can make shortcodes with the use of WordPress Shortcode API, as it enables users to take benefits of existing theme features from any test-based area on WordPress site.

The shortcode functions can be created in three simpler steps-

1. Create function in function.php and register
function display_related_posts($array = array()) {
   <div class="col-md-12 remove-padding m-t20">Shortcode function defination</div>
}
add_shortcode('display_related_posts', 'display_related_posts');

2. Now you can call anywhere in file or editor with this function.
do_shortcode('[display_related_posts]');

We can use simplay WP_Query() with post_parent and post_type, then we can get all child pages of that particular parent page.

The following steps need to use in order to customize image sizes in the CSM WordPress. Edit your existing theme’s funcation.php file and add the following code add_image_size( 'image_size_name', 1000, 590 );
