A WordPress theme detector is a tool that can analyze a website and determine which WordPress theme is being used to design the site. These tools work by analyzing the source code of a website and looking for specific patterns or code snippets that are associated with a particular theme.
There are many theme detectors available online, and they are often free to use. Some popular options include:
- What WordPress Theme Is That? (https://whatwpthemeisthat.com/)
- WordPress Theme Detector (https://www.wpthemedetector.com/)
- IsItWP (https://isitwp.com/wordpress-theme-detector/)
- Theme Detector (https://themedetector.com/)
Keep in mind that a WordPress site can be customized in many ways so it’s possible that a theme detector might not always correctly identify the theme that is being used or might not correctly identify a theme that has been heavily customized.
Also, Detecting the theme alone won’t give much of an insight as all the major theme providers like Divi, Avada etc have a similar structure, So usually it’s important to find the theme along with the plugins being used on the website, as that would give an idea of what sort of functionalities the website have.
Here is an example of a simple PHP script that you can use to detect the WordPress theme being used on a website:
<?php
$theme_data = wp_get_theme();
echo '<h2>' . $theme_data->Name . '</h2>';
echo '<p>' . $theme_data->Version . '</p>';
echo '<p>' . $theme_data->Template . '</p>';
echo '<p>' . $theme_data->Author . '</p>';
echo '<p>' . $theme_data->AuthorURI . '</p>';
?>
This script uses the wp_get_theme()
function to get information about the currently active WordPress theme. The information that is returned includes the name of the theme, its version, the template it is based on, and the author and author URI.
You can use this script in your WordPress site by creating a new page template, copying this code and pasting it into the template file, and then creating a new page that uses the new template.
Please note this script assumes that you are working on a WordPress site and have the knowledge of how to create a page template. Also, this script will work only if you put this code on the site where WordPress is installed, otherwise, it will return an error.
It is important to note that this script is just a basic example and it’s not a full-featured WordPress theme detector. It will return the data of the current theme activated on the website. Also, the same data can be seen by going to Appearance->Themes on the WordPress Dashboard.
Here’s an example of how you might use JavaScript to detect the WordPress theme being used on a website:
<!DOCTYPE html> <html> <head> <script> function detectWordPressTheme() { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { var themeData = JSON.parse(this.responseText); var themeName = themeData.name; var themeAuthor = themeData.author; var themeVersion = themeData.version; document.getElementById("theme-name").innerHTML = themeName; document.getElementById("theme-author").innerHTML = themeAuthor; document.getElementById("theme-version").innerHTML = themeVersion; } }; xhttp.open("GET", "/wp-json/wp/v2/themes", true); xhttp.send(); } </script> </head> <body onload="detectWordPressTheme()"> <h2>Theme Name: <span id="theme-name"></span></h2> <p>Theme Author: <span id="theme-author"></span></p> <p>Theme Version: <span id="theme-version"></span></p> </body> </html>
This code uses the XMLHttpRequest()
object to make a GET request to the /wp-json/wp/v2/themes
endpoint of a WordPress site. The endpoint returns a JSON object containing information about all the installed themes on the site. The code then parses the response and extracts the name, author, and version of the currently active theme, and displays it in the corresponding elements in the HTML body.
The onload
attribute in the body element runs the detectWordPressTheme function when the page is loaded, which is where the Xmlhttprequest is sent. This means that this code will only work when you run this HTML file on a server with WordPress running on the same domain, otherwise the request will fail.
This is a basic example and it’s not a full-featured WordPress theme detector. It will return the data of the current theme activated on the website. This code snippet also assumes that the WordPress site has the REST API enabled and accessible.
Keep in mind that the above script will not work if you open the HTML file from your local machine, it must be run on a web server that has WordPress installed on it.
