Function Name: get_avatar
The get_avatar function in WordPress retrieves the avatar (profile picture) of a user based on their email address or user ID. This function is commonly used in WordPress themes to display the author’s avatar or the avatar of a commenter.
The get_avatar function takes three optional parameters: user ID or email address, size of the avatar (default size is 96 pixels), and a fallback image URL in case the user doesn’t have an avatar. The function returns the HTML code to display the avatar.
Example Usage:
To display the avatar of the current post author with a size of 150 pixels, you can use the following code:
<?php echo get_avatar( get_the_author_meta( 'ID' ), 150 ); ?>This will display the author’s avatar with a size of 150 pixels. If the author doesn’t have an avatar, the function will use the default Gravatar image.
