Definition: The `/wp-includes/link.php` file in WordPress typically contains JavaScript code that is used to link external resources (like images, videos or other files) to the website.
Definition:
-
WP-includes
: This part refers to the WordPress includes folder, which is included at the very beginning of every page's HTML source. It contains all the necessary WordPress components and plugins required by any webpage to be rendered properly.
- `/wp-includes/link.php`: This is a PHP script that runs after the initial HTML markup has been written into the `html` tag inside the `
` or `` tags.
Purpose:
The `/wp-includes/link.php` file provides an easy way for WordPress users to link their resources (like images, videos, etc.) to the website. It is especially useful if you're trying to add external links to your site but want to make sure they are properly referenced in all of your other files.
Structure:
- `/wp-includes/link.php`: The root of the script file.
- `function wp_link()`: This function defines what happens when a link is clicked. It sets some global variables, such as the URL where the link should be displayed on the website (in this case, it's "index.php").
- `if (isset($GLOBALS['wp_current_url'])) {` (PHP statement): The check to see if there are any external links in the current URL.
- `$wp_link = 'http://example.com';` (PHP statement): The link that is being linked to.
- `$GLOBALS['wp_current_url'] = $wp_link;` (PHP statement): Sets a new global variable that holds the current URL for WordPress.
Example of Usage:
If you want to link an external image, you could do something like this:
```
media_large_link) . '">Please, see it!';
} else {
echo 'No such post';
}
}
?>
```
This script would set the `wp_current_url` variable to a URL with an image link and then display that link on your website.
