    The has_header_video() function in WordPress is designed to check whether a header video is set for the current theme. This is a simple yet useful function, particularly for themes that support video headers. Here's a detailed explanation and sample usage:

    • Function Signature: has_header_video(): bool
    • Purpose: To determine if a header video is currently set in the theme.
    • Return Type: This function returns a boolean value (bool).

    Description:

    The has_header_video() function is part of WordPress's theme customization API. It's used to check if a header video has been set for the current theme. This is useful when your theme allows for a video to be displayed in the header area, and you want to dynamically change the layout or style of your site based on whether a header video is present.

    See Also:

    • get_header_video_url(): While has_header_video() checks for the existence of a header video, get_header_video_url() retrieves the URL of the current header video if it's set. You can use these two functions together to first check if a header video is present and then retrieve its URL.

    Sample Usage:

    if ( has_header_video() ) {
        echo '<div class="header-video">';
        the_custom_header_markup(); // Outputs the header video markup
        echo '</div>';
    } else {
        // Fallback content if no header video is set
        echo '<div class="header-image">';
        the_header_image_tag(); // Outputs the header image tag
        echo '</div>';
    }
    

    In this example, the has_header_video() function is used in a conditional statement to check if a header video is set. If it is, the theme outputs the necessary markup to display the video. If not, it falls back to displaying a header image.

    This function is particularly handy for theme developers who want to provide a dynamic and engaging user experience by utilizing multimedia elements like videos in the theme design.
