In WordPress, getting the base URL is an essential task that you need to perform frequently. The base URL is the part of your site address that remains the same regardless of the page or post the user is viewing. It's needed for many functionalities, such as links or redirection, where you have to direct the user to a unique address.
There are several methods to get the base URL in WordPress, but it can be confusing for beginner developers to understand the correct way. Therefore, we will discuss different methods to get the base URL in WordPress and explain each method with useful code examples.
Method 1: Using The WordPress Function home_url()
The simplest and most commonly used method to get the base URL in WordPress is by using the home_url() function. This function returns the base URL of your WordPress website.
Code Example:
Explanation:
The home_url() function returns the home URL of your WordPress website with proper HTTP or HTTPS protocol. If you want to set a path or parameter with the base URL, you can pass them as a parameter to the function.
For example, to get the base URL with custom parameters, use the following code:
Code Example:
Method 2: Using WordPress Function site_url()
Another WordPress core function to retrieve the base URL is site_url(). This function works the same as home_url(), and it returns the same URL with the same protocol as the home_url(). The only difference is that this function is used to get the URL for the WordPress installation directory.
Code Example:
Explanation:
The site_url() function returns the location of the home or site directory where WordPress core files are stored. The home_url() function is the recommended way to get the base URL in WordPress, but you can use this function if you want to point to the location of your WordPress installation directory.
Method 3: Using Relative URL
A relative URL is a URL that only contains the path from the current page or post and not the entire URL. When working with relative URLs, you can use the forward-slash '/' to point to the base URL.
Code Example:
Explanation:
The '/' in the above code will refer to the base URL of your WordPress website. When working with relative URLs, it's essential to note that they are relative to the page or post root directory. Therefore, be careful to use relative URLs when pointing to different pages or websites.
Method 4: Using $_SERVER SuperGlobal Variable
Another way to retrieve the base URL in WordPress is by using the $_SERVER superglobal variable. This variable contains information about the server environment, including the URL and base URL.
Code Example:
Explanation:
The $_SERVER['HTTP_HOST'] contains the domain name of the server where the WordPress website is hosted. We add 'http://' in front of the domain name, so the URL becomes an absolute URL.
Method 5: Using The WordPress Function get_bloginfo()
The get_bloginfo() function retrieves the blog information of the current WordPress website, such as the site title, tagline, URL, and more. We can retrieve the base URL from this function using the 'url' parameter.
Code Example:
Explanation:
The above code will retrieve the base URL of your WordPress website by using the 'url' parameter in the get_bloginfo() function. It's necessary to know that the 'url' parameter only works with a single-site WordPress website. If you're using a WordPress multisite installation, use the 'siteurl' parameter instead of 'url.'
Conclusion:
We have discussed multiple ways to retrieve the base URL of your WordPress website with code examples that you can directly use in your functions.php file or theme files. Always use the home_url() function to get the base URL if you're unsure which function to use. We hope this article helped you understand the importance and usage of different methods to get the base URL in WordPress.
