Using Url Parameters in WordPress

In WordPress, you can use parameters in your URLs to pass data to your site and retrieve it in your PHP code. This is useful for creating dynamic and customizable URLs that can be used to filter content, search for specific information, and more.

To use parameters in your URLs, you can add a question mark followed by the name of the parameter and its value, like this:

www.example.com/?param=name

In this example, “param” is the name of the parameter and “name” is its value.

To retrieve the value of the parameter in your PHP code, you can use the $_GET array, like this:

$param = $_GET['param'];

if (isset($_GET['param'])) {
  $param = $_GET['param'];
} else {
  //Handle the case where there is no parameter
}

This will retrieve the value of the “param” parameter and store it in the $param variable.

You can then use this variable in your code to filter content, search for specific information, or perform other actions based on the value of the parameter.

For example, you could use the following code to retrieve all posts with a specific title:

$title = $_GET['param'];
$args = array('post_type' => 'post', 'posts_per_page' => -1, 'title' => $title);
$the_query = new WP_Query($args);

This code will retrieve all posts with the specified title, based on the value of the “param” parameter in the URL.

By using parameters in your URLs and retrieving them in your PHP code, you can create dynamic and customizable content that can be easily filtered and searched by users. This is a powerful feature of WordPress that can help you build more flexible and user-friendly websites.
