You can see my working example here:

I ended up using my own solution loosely based off the developers last reply and my previous attempts. I am not an expert programmer by any means though, so I don’t know if this would be considered a proper or efficient way, but it is working for my site.

Here was my solution, this was added to my child theme’s functions.php file:

// Set Vehicle Filter for Session//
function vehicle_filter_setcookie() {
    //Detect WOOF get variables in URL and save to session data if they exist//
    if (!is_admin() && isset($_GET['vehicle']) && isset($_GET['product_make'])) {
        $_SESSION['ses_product_make'] = $_GET['product_make'];
    }

    //This IF statement prevents WOOF results from overriding homepage content//
    if (!is_admin() && $_SERVER["REQUEST_URI"] != '/' && isset($_SESSION['ses_product_make'])) {
        $_GET['product_make'] = $_SESSION['ses_product_make'];
    }
    //Unset WOOF selections if 'reset_vehicle' variable is posted//
    if (isset($_POST['reset_vehicle'])) {
        unset($_GET['product_make']);
        unset($_SESSION['ses_product_make']);
    }
}
add_action( 'init', 'vehicle_filter_setcookie' );

Then I created a form to clear the session data, therefor clearing WOOF settings. This is what I used for that:

<form action="" method="post">
	<input type="hidden" name="reset_vehicle" value="true" />
	<button>CHANGE VEHICLE</button>
</form>

I tried this with no luck…

In functions.php

// Set Vehicle Filter for Session//
function vehicle_filter_setcookie() {
    if (!is_admin() && isset($_GET['vehicle']) && isset($_GET['product_make'])) {
        $_SESSION['product_make'] = $_GET['product_make'];
    }
//Reset post/session data if reset_vehicle is posted
    if (isset($_POST['reset_vehicle'])) {
        unset($_GET['product_make']);
        unset($_SESSION['product_make']);
    }
}
add_action( 'init', 'vehicle_filter_setcookie' );

function vehicle_filter_restore() {
    return apply_filters('woof_get_request_data', $_SESSION);
}

In my header.php file:

<?php
    if (is_woocommerce()){
        vehicle_filter_restore();
    }
?>

Am I doing it wrong?

Thank you for your reply RealMag777,

Can you please give me an example of how I would use the get_request_data() function in my script I posted above?

The knowledge-base you linked doesn’t show any examples of usage or any description of what the function does…

Thank you!!
