Creating audio player with wp_audio_shortcode in WordPress

The wp_audio_shortcode function in WordPress is a built-in function designed to handle audio files. It is responsible for generating the necessary HTML output for audio files that are embedded in posts, pages, or custom post types using shortcodes.

This function is part of the WordPress Shortcode API, a set of functions allowing developers to create shortcodes which users can type into post text. The wp_audio_shortcode function specifically handles the audio shortcode, translating it into the appropriate HTML markup for an audio player.

When a WordPress shortcode for an audio file is encountered in the content, the wp_audio_shortcode function processes it and generates the necessary HTML for an audio player that can play the specified audio file. The audio player’s appearance and functionality may vary depending on the browser and the settings specified in the shortcode.

By using this function, WordPress ensures a consistent and standardized way of embedding audio files across different themes and plugins. This function also abstracts the complexities of generating the necessary HTML for an audio player, making it easier for users to embed audio files in their content.

Parameters Accepted by the wp_audio_shortcode Function

The wp_audio_shortcode function in WordPress accepts two parameters:

  • $attr (array), which is a required parameter. This represents the attributes of the audio shortcode.
  • $content (string), which is an optional parameter. This parameter has a default value of an empty string (”) and represents the shortcode content.

If the function does not accept any parameters, it will be explicitly stated.

Return Value of the wp_audio_shortcode Function

The wp_audio_shortcode function returns either a string or void. The returned string is the HTML content that is used to display the audio. If there is no return value, the function will return void.

Examples

How to use wp_audio_shortcode to display an audio file

The wp_audio_shortcode function is commonly used to display an audio file on a WordPress page or post. Here is a basic usage:

$attr = array(
 'src' => 'http://example.com/wp-content/uploads/my-audio-file.mp3',
 'loop' => '',
 'autoplay' => '',
 'preload' => 'none'
);
echo wp_audio_shortcode( $attr );

This code snippet uses the wp_audio_shortcode function to display an audio player on a WordPress page or post. The audio file is specified by the ‘src’ attribute in the $attr array. The ‘loop’, ‘autoplay’, and ‘preload’ attributes are set to empty strings, meaning that the audio file will not loop or autoplay, and it will not preload when the page loads.

How to use wp_audio_shortcode with autoplay

Here is an example of using the wp_audio_shortcode function with the ‘autoplay’ attribute set to ‘on’, meaning the audio file will automatically play when the page loads:

$attr = array(
 'src' => 'http://example.com/wp-content/uploads/my-audio-file.mp3',
 'autoplay' => 'on'
);
echo wp_audio_shortcode( $attr );

This code snippet is similar to the previous one, but the ‘autoplay’ attribute is set to ‘on’. This means that the audio file will automatically start playing when the page loads.

How to use wp_audio_shortcode with loop

Here is an example of using the wp_audio_shortcode function with the ‘loop’ attribute set to ‘on’, meaning the audio file will automatically loop when it reaches the end:

$attr = array(
 'src' => 'http://example.com/wp-content/uploads/my-audio-file.mp3',
 'loop' => 'on'
);
echo wp_audio_shortcode( $attr );

This code snippet is similar to the previous ones, but the ‘loop’ attribute is set to ‘on’. This means that the audio file will automatically start over from the beginning when it reaches the end.
