Dynamically generated URL and Content page

Question

I am in need of some advice. I have a section on my home page dynamically pulling in a list of terms from a custom table in the WP db. I have made a unique custom URL for each of these terms based on test code:

<a href="<?php bloginfo('url'); ?>/test-directory/test-code/<?php echo $record->test_code; ?>">

This works fine. My next step is to have these URLs, when clicked, load the accompanying dynamic content into a template. I tried the code below to create rewrite rules to point to a template but it just isn't working. It doesn't load the template but the default blog template. I am using a child theme but this should work:

function my_add_query_vars( $qvars ) {
    $qvars[] = 'test-directory';
        $qvars[] = 'test-code';
        return $qvars;
}

add_action('query_vars', 'my_add_query_vars');


function my_add_rewrite_rules( $wp_rewrite ) {
    $newrules = array();
    $new_rules['^test-directory/(.*)/(.*)'] = 'index.php?test-directory=$matches[1]test-code=$matches[2]';
    $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
}

add_action('generate_rewrite_rules', 'my_add_rewrite_rules');

function my_template_redirect() {
    if( get_query_var('test-code') ) {
        include_once(locate_template('template-faq-fullwidth.php', true));
        exit();
    }
}

add_action('template_redirect','template_redirect');

Any help is appreciated as always.Thanks.

Firstly, don't forget to always flush your rewrite rules by going to Settings -> Permalinks and just clicking on Save Changes

Now on your problem, it seems that you're missing an '&' in your query:

$new_rules['^test-directory/(.*)/(.*)'] = 'index.php?test-directory=$matches[1]&test-code=$matches[2]';

Notice the & after $matches[1]

On the other hand, your 'template_redirect' action is not calling the correct function (template_redirect instead of my_template_redirect)
