Function Name: wp_get_themes
WordPress is all about themes that define the overall look and feel of a website. The wp_get_themes function is a core WordPress function that retrieves an array of installed themes. This function provides a list of all installed themes, including both active and inactive ones, with their details such as name, version, author, description, etc.
This function is very useful for theme developers who want to create a theme selection interface for their users. It can be used to retrieve all available themes and display them in a dropdown list or a grid of thumbnails. It can also be used to check if a theme is installed or not, which can be helpful for plugin developers who want to check if a specific theme is installed before performing certain actions.
Here’s an example usage code for wp_get_themes:
$themes = wp_get_themes();
foreach ($themes as $theme) {
echo '<h2>' . $theme->name . '</h2>';
echo '<p>' . $theme->description .'</p>';
echo '<img src="' . $theme->get_screenshot() . '" alt="' . $theme->name . ' Screenshot">';
}In this example, we’re using a foreach loop to iterate through all the themes and display their name, description, and screenshot. The get_screenshot() method is a theme class method that returns the URL of the theme’s screenshot image. This code can be used in a WordPress theme or plugin to display a list of all available themes and their details.
