What is the purpose of the php.ini file?

 The PHP configuration file, php.ini, is the final and most immediate way to affect PHP's functionality. The php.ini file is read each time PHP is initialized. in other words, whenever httpd is restarted for the module version or with each script execution for the CGI version.

How do you enable error reporting in PHP?

 PHP allows us to choose whether or not to display errors to users. There are three ways to enable or disable error reporting in PHP:

Method 1: You can turn the display error parameter in the php.ini file on or off. When it’s on, errors are shown; when it’s off, there are no errors shown or reported. To do this, locate the display error parameter in the php.ini file, then set its value to “on.” Restart the web server's various services. The PHP script's errors will now be visible to end users. Set the display error parameter to “off” to stop reporting errors. The off argument indicates that users won't see any errors.

Method 2: Using the mini set() function is the second way to enable or stop error reporting. The ability to modify the configuration options in the php.ini file is a built-in feature of the PHP programming language. It requires two inputs: the name of the setting you want to change and the value you want to assign.

Method 3: You can also utilize the error reporting() function, a native PHP function, to enable error reporting. This function controls which PHP faults are reported and sets the error reporting directive during runtime. Given that PHP has multiple error levels, this method also aids in setting the various levels for the runtime (duration) of your script. This function accepts parameters for error names like E ERROR, E WARNING, E PARSE, etc., allowing these errors to be reported.

How to Create Custom Post Types in WordPress

 We only get three built-in content types at the backend when we install WordPress, i.e., posts, pages, and media. However, today WordPress has become quite flexible and advanced.

The approach to adding more post types also has expanded. The diversified usage demands more content types because posts, pages, and media are not enough, and here is where WordPress custom post type comes in handy.

What Is a WordPress Custom Post Type?

Custom post types are used to convert a regular WordPress website into a content management system. As the name suggests, you can use custom post types to create various content types for your website.

Besides that, one can find several post types available by default in WordPress installation, including:

• Post – blog post
• Page – static page
• Attachment – attached media
• Revision – post revision
• Navigation Menu – nav menu
• WordPress supports an unlimited number of Custom Post Types. You can create your custom posts and call them up wherever you want.
• For example, if you run a News website and want to add a custom post type titled “News.” Once created, the news post-type would have its own menu in the WordPress dashboard admin area. Additionally, you can create multiple post types, such as Movies, Portfolios, etc.

• Follow the steps below to create a custom post type on a WordPress website:

  • Navigate to the function.php file from your WordPress theme directory
  • Add the following code to the function.php file
  1. /* Custom Post Type Start */
  3. function create_posttype() {
  4. register_post_type( 'news',
  5. // CPT Options
  7. array(
  8. 'labels' => array(
  9. 'name' => __( 'news' ),
  10. 'singular_name' => __( 'News' )
  11. ),
  12. 'public' => true,
  13. 'has_archive' => false,
  14. 'rewrite' => array('slug' => 'news'),
  15. )
  16. );
  17. }
  18. // Hooking up our function to theme setup
  19. add_action( 'init', 'create_posttype' );
  21. /* Custom Post Type End */
  • Once you’ve added the code, the News post-type will automatically appear in the admin area

  

  • When creating custom post types, it is necessary to use init for the hook in add_action(), and the register_post_type() function will take the arguments
  1. /*Custom Post type start*/
  3. function cw_post_type_news() {
  5. $supports = array(
  6. 'title', // post title
  7. 'editor', // post content
  8. 'author', // post author
  9. 'thumbnail', // featured images
  10. 'excerpt', // post excerpt
  11. 'custom-fields', // custom fields
  12. 'comments', // post comments
  13. 'revisions', // post revisions
  14. 'post-formats', // post formats
  15. );
  17. $labels = array(
  18. 'name' => _x('news', 'plural'),
  19. 'singular_name' => _x('news', 'singular'),
  20. 'menu_name' => _x('news', 'admin menu'),
  21. 'name_admin_bar' => _x('news', 'admin bar'),
  22. 'add_new' => _x('Add New', 'add new'),
  23. 'add_new_item' => __('Add New news'),
  24. 'new_item' => __('New news'),
  25. 'edit_item' => __('Edit news'),
  26. 'view_item' => __('View news'),
  27. 'all_items' => __('All news'),
  28. 'search_items' => __('Search news'),
  29. 'not_found' => __('No news found.'),
  30. );
  32. $args = array(
  33. 'supports' => $supports,
  34. 'labels' => $labels,
  35. 'public' => true,
  36. 'query_var' => true,
  37. 'rewrite' => array('slug' => 'news'),
  38. 'has_archive' => true,
  39. 'hierarchical' => false,
  40. );
  41. register_post_type('news', $args);
  42. }
  43. add_action('init', 'cw_post_type_news');
  45. /*Custom Post type end*/

  $supports: Specifies that the post type is compatible and supports all essential features.

  $labels: Specifies that the post type is referred correctly to the admin area.

  $args: Specifies a permalink slug of the news and a menu position located just beneath the Posts menu.
