Extracting a parameter from a URL in WordPress

Extracting a Parameter from a URL in WordPress: Demystifying the Mechanics 🧩

So, you want to extract a parameter from a URL in your beloved WordPress site, eh? 🌐 No worries! We've got your back! In this guide, we will unravel the mechanics behind extracting those sneaky parameters and equip you with simple solutions. Let's dive in, shall we? 💪

The Scenario 🤔

Imagine this: you have a URL like www.fioriapts.com/?ppc=1, and you want to extract that parameter value (in this case, 1) within your WordPress site. But how do you go about doing that? 🤷‍♂️

The Function You'll Love ❤️

You might be thinking, "Oh, I can write a function in the functions.php file to handle this!" 🤓 And you're absolutely right! WordPress provides us with a nifty function called get_query_var() that does wonders when it comes to extracting URL parameters.

Solution 1: Basic Extraction 🧰

Let's start with the basics. To extract a parameter, you can use the following code snippet:

$parameter = get_query_var('ppc');

BOOM! 💥 Just like that, you have extracted the value of the "ppc" parameter from the URL! You can now use the $parameter variable in your PHP code as you please. 🎉

Solution 2: Default Value 🔄

But wait, there's more! What if the parameter doesn't exist in the URL? No worries! You can provide a default value to fallback on using the following code:

$parameter = get_query_var('ppc', 'default_value');

With this solution, if the "ppc" parameter is not present, the $parameter variable will be set to the default value you specify. How convenient! 😎

Solution 3: Handling URL Rewrites 🌈

Now, let's say you have friendly, pretty, and SEO-friendly URLs like www.fioriapts.com/ppc/1 instead of www.fioriapts.com/?ppc=1. Fear not! We have a solution for you too! 😮

To extract the parameter in this scenario, you need to modify your functions.php file and add the following code:

function custom_rewrite_rule() {
    add_rewrite_rule('^ppc/([^/]*)/?','index.php?ppc=$matches[1]','top');
}
add_action('init', 'custom_rewrite_rule', 10, 0);

With this solution, you can now extract the parameter using the same code as before:

$parameter = get_query_var('ppc');
