Function and usage of print_embed_styles() in wordpress


Answers ( 1 )


    The print_embed_styles() function in WordPress is used to print the CSS styles in the header of an embed iframe. This function is particularly useful when you are embedding content from your WordPress site into another website and want to maintain consistent styling. Here's a detailed explanation and an example of how it's used:

    Function: print_embed_styles()

    • Purpose: To print CSS styles in the embed iframe header.
    • Usage: This function is typically used in the WordPress embed template.
    • Behavior: When content from a WordPress site is embedded on another site, WordPress generates an iframe to display this content. The print_embed_styles() function ensures that the necessary CSS styles are included in this iframe, so the embedded content maintains the styling of the original WordPress site.
    • Location: This function is usually called in the wp-includes/embed-template.php file, which is part of the WordPress core.

    Sample Usage:

        // This code would typically be placed in the embed template file
        function theme_embed_styles() {
            // Custom embed styles
            echo '<style type="text/css">
                body { background-color: #f3f3f3; }
                .post { border: 1px solid #ddd; padding: 20px; }
        add_action( 'embed_head', 'theme_embed_styles' );
    • In this example, theme_embed_styles() is a custom function that defines additional CSS styles for embedded content.
    • The add_action() function hooks theme_embed_styles to the embed_head action, which is triggered in the head section of the embed template.
    • When the embed template is loaded, the theme_embed_styles() function is executed, and the defined CSS styles are printed in the head of the document, thereby styling the embedded content.

    This is a simplified example. In a real-world scenario, you might have more complex styles or even include external style sheets. The key point is that print_embed_styles() is central to ensuring that embedded WordPress content looks consistent and maintains the styling of the source site.
