How to use the get_post_embed_html function in WordPress

The get_post_embed_html function in WordPress is designed to generate HTML markup for embedding a post into an external site or application. This function plays a pivotal role in the WordPress oEmbed feature, which allows the embedding of WordPress posts into other websites.

When the get_post_embed_html function is called, it returns an HTML string that represents the post. This HTML string can then be used in the context of another website or application, allowing the post to be displayed outside of its original WordPress environment.

The HTML string returned by the get_post_embed_html function includes the post’s title, an excerpt of its content, and a link back to the original post. The function also includes the necessary scripts and styles to ensure that the embedded post is displayed properly.

The get_post_embed_html function is part of WordPress’s larger system for handling oEmbeds, which includes several other functions and filters. This system allows WordPress to handle both the embedding of its own posts into other sites, and the embedding of external content into WordPress posts.

Parameters Accepted by the get_post_embed_html Function

The get_post_embed_html function in WordPress accepts three parameters. These parameters are as follows:

  • $width (int): This is a mandatory parameter which specifies the width for the response.
  • $height (int): This is also a required parameter, and it defines the height for the response.
  • $post (int|WP_Post): This parameter is optional with a default value of null. It represents the post ID or object. If not specified, the global $post is used by default.

Return Value of the get_post_embed_html Function

The get_post_embed_html function returns a string or a boolean false. The function will return the embed code if the operation is successful. If the post does not exist, the function will return false.

If the function does not accept any parameters, it will be explicitly stated. However, in the case of the get_post_embed_html function, it does accept parameters as detailed above.

Examples

How to Get the Embed HTML of a Post with Specific Width and Height

This example demonstrates how to use the get_post_embed_html function to get the embed HTML of a specific post with a specified width and height.

$post_id = 123; // replace with your post ID
$width = 600; // replace with your desired width
$height = 400; // replace with your desired height

$embed_html = get_post_embed_html($width, $height, $post_id);

if ($embed_html !== false) {
 echo $embed_html;
} else {
 echo "The post does not exist.";
}

In this code snippet, we first specify the post ID, width, and height. We then call the get_post_embed_html function with these parameters. If the function returns a string (the embed HTML), we output it. If the function returns false (indicating that the post doesn’t exist), we output a message to that effect.

How to Get the Embed HTML of the Current Post

This example demonstrates how to use the get_post_embed_html function to get the embed HTML of the current post in the loop.

$width = 600; // replace with your desired width
$height = 400; // replace with your desired height

$embed_html = get_post_embed_html($width, $height);

if ($embed_html !== false) {
 echo $embed_html;
} else {
 echo "The post does not exist.";
}

In this code snippet, we do not specify a post ID when calling the get_post_embed_html function. This means that the function will use the global $post variable, which represents the current post in the loop. The rest of the code is the same as in the previous example.

Conclusion

The get_post_embed_html function in WordPress is a tool that retrieves the HTML needed to display a post in an iframe. This function is typically used when you want to embed a WordPress post into another website. The HTML that this function generates includes the necessary code to display the post’s title, content, and metadata, formatted in a way that is suitable for embedding. By understanding and utilizing the get_post_embed_html function, developers can seamlessly integrate WordPress post content into other web platforms.
